1.2.1  RF Exposure Guidelines 
To  ensure  that  exposure  to  RF  electromagnetic  energy  is  within  the  FCC  allowable 
limits for occupational use and/or the exposure limit values in Annex A of EU Directive 
2004/40/EC, always adhere to the following guidelines: 
 DO NOT operate the radio without a proper antenna attached, as this may damage the radio and may 
also cause the FCC RF exposure limits and/or the exposure limit values in Annex A of EU Directive 
2004/40/EC to be exceeded. A proper antenna is the antenna supplied with this radio by Harris or an 
antenna specifically authorized by Harris for use with this radio. (Refer to Table 6-1.) 
 DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more 
than 50% of the time can cause FCC RF exposure compliance requirements and/or the exposure limit 
values in Annex A of EU Directive 2004/40/EC to be exceeded. The radio is transmitting when the 
“TX” indicator appears in the display. The radio will transmit by pressing the “PTT” (Push-To-Talk) 
button. 
 ALWAYS transmit using low power  when possible. In addition to conserving battery charge, low 
power can reduce RF exposure. 
WARNING
CAUTION

  14221-1100-2010, Rev. E 
15 
 ALWAYS use Harris authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). Use of 
unauthorized  accessories  may  cause  the  FCC  Occupational/Controlled  Exposure  RF  compliance 
requirements  and/or  the  exposure  limit  values  in  Annex  A  of  EU  Directive  2004/40/EC  to  be 
exceeded. (Refer to Table 1-1.) 
 As  noted  in  Table  1-1,  ALWAYS  keep  the  housing  of  the  transmitter  AT  LEAST  1.6  cm  (0.63 
inches) from the body and at least 2.5 cm (1.0 inch) from the face when transmitting to ensure FCC 
RF exposure compliance requirements and/or the exposure limit values in Annex A of EU Directive 
2004/40/EC are not exceeded. However, to provide the best sound quality to the recipients of your 
transmission, Harris recommends you hold the microphone at least 5 cm (2 inches) from mouth, and 
slightly off to one side.

1.3  OPERATING TIPS 
Antenna location and condition are important when operating a portable radio.  Operating the radio in low 
lying areas or terrain, under power lines or bridges, inside of a vehicle or in a metal framed building can 
severely reduce the range of the unit.  Mountains can also reduce the range of the unit.  
In areas where transmission or reception is poor, some improvement may be obtained by ensuring that the 
antenna is vertical.  Moving a few yards in another direction or moving to a higher elevation may also 
improve  communications.    Vehicular  operation  can  be  aided  with  the  use  of  an  externally  mounted 
antenna.  
Battery condition is another important factor in the trouble free operation of a portable radio.  Always 
properly charge the batteries.  
1.3.1  Efficient Radio Operation 
Keep the antenna in a vertical position when receiving or transmitting a message.  
Do  not  hold  the  antenna  when  receiving  a  message  and,  especially,  do  not  hold  when  transmitting  a 
message.  
Do NOT hold onto the antenna when the radio is powered on! 
1.3.2  Antenna Care and Replacement 
Do NOT use the portable radio with a damaged or missing antenna. A minor burn 
may  result  if  a  damaged  antenna  comes  into  contact  with  the  skin.  Replace  a 
damaged antenna immediately. Operating a portable radio with the antenna missing 
could cause personal injury, damage the radio, and may violate FCC regulations. 
Use only the supplied or approved antenna. Unauthorized antennas, modifications, 
or  attachments  could  cause  damage  to  the  radio  unit  and  may  violate  FCC 
regulations. (Refer to Table 6-1.)

1.3.5  Electric Blasting Caps  
To  prevent  accidental  detonation  of  electric  blasting  caps,  DO  NOT  use  two-way 
radios within 1000 feet of blasting operations. Always obey the "Turn Off Two-Way 
Radios" signs posted where electric blasting caps are being used. (OSHA Standard: 
1926.900) 
1.3.6  Potentially Explosive Atmospheres 
Areas  with  potentially  explosive  atmospheres  are  often,  but  not  always,  clearly 
marked. These may be fuelling areas, such as gas stations, fuel or chemical transfer 
or storage facilities, and areas where the air contains chemicals or particles, such as 
grain, dust, or metal powders. 
Sparks in such areas could cause an explosion or fire resulting in bodily injury or 
even death. 
Turn off two-way radios when in any area with a potentially explosive atmosphere. It 
is rare, but not impossible that a radio or its accessories could generate sparks.

2.2.1  Directives sur l’exposition aux RF 
AVERTISSEMENT
Pour s’assurer que l’exposition à l’énergie électromagnétique des RF se situe dans les 
limites acceptables de la FCC pour l’utilisation professionnelle, respectez toujours les 
directives suivantes : 
 N’utilisez PAS la radio sans qu’une antenne appropriée y soit connectée, car ceci peut endommager la 
radio et également causer un dépassement des limites d’exposition aux RF de la FCC. Une antenne 
appropriée est celle fournie par Harris avec cette radio, ou une antenne spécifiquement autorisée par 
Harris pour être utilisée avec cette radio. (Reportez-vous à Table 6-1.) 
 Ne  transmettez  PAS  pendant  plus  de  50 % de  la  durée  d’utilisation  totale  de  la  radio  (« cycle  de 
service de 50 % »). La transmission pendant plus de 50 % du temps peut causer un dépassement des 
exigences  de  conformité  de  la  FCC  en  matière  d’exposition  aux  RF.  La  radio  transmet  lorsque 
l’indicateur « TX » apparaît sur l’affichage. La radio transmet lorsqu’on appuie sur le bouton « PTT » 
(bouton de microphone). 
 Transmettez TOUJOURS en basse puissance lorsque possible. En plus de préserver la charge de la 
pile, une faible puissance réduit l’exposition aux RF. 
 Utilisez  TOUJOURS  des  accessoires  autorisés  Harris  (antennes,  piles,  pinces  de  ceinture,  haut-
parleurs/micros,  etc.).  L’utilisation  d’accessoires  non  autorisés  peut  entraîner  un  dépassement  des 
exigences  de  conformité  pour  une  exposition  aux  RF  professionnelle  ou  contrôlée  de  la  FCC. 
(Reportez-vous à Table 1-1.) 
 Tel qu’indiqué dans Table 1-1, conservez TOUJOURS l’appareil et son antenne à AU MOINS 1,6 cm 
(0,63 po) du corps, et à au moins 2,5 cm (1,0 po) du visage pendant la transmission, pour vous assurer 
de  ne  pas  dépasser  les  exigences  de  conformité  de  la  FCC  en  matière  d’exposition  aux  RF. 
Cependant,  pour  offrir  la  meilleure  qualité  sonore  aux  auditeurs  de  votre  transmission,  Harris 
recommande de tenir le microphone à au moins 5 cm (2 po) de votre bouche et légèrement déplacé 
sur un côté.

L’emplacement et l’état de l’antenne sont importants pour l’utilisation d’une radio portative. L’utilisation 
de la radio dans des zones de faible élévation, sous des lignes électriques ou des ponts, à l’intérieur d’un 
véhicule  ou  dans  un  immeuble  à  ossature  métallique,  peut  réduire  la  portée  de  l’appareil  de  manière 
considérable. Les montagnes peuvent également réduire la portée de l’unité.  
Dans les zones où la transmission ou la réception est insatisfaisante, certaines améliorations peuvent être 
obtenues  en  s’assurant  que  l’antenne  est  verticale.  Se  déplacer  de  quelques  mètres  dans  une  autre 
direction ou  à  un emplacement  plus  élevé peut  également améliorer  les  communications.  L’utilisation 
d’une antenne fixée à l’extérieur peut faciliter le fonctionnement dans un véhicule.  
L’état de la pile est un autre facteur important d’une utilisation sans tracas d’une radio portative. Chargez 
toujours correctement la pile.  
2.4.1  Utilisation Efficace de la Radio 
Gardez l’antenne dans une position verticale pendant la réception ou la transmission d’un message.

MISE EN GARDE
Ne tenez PAS l’antenne lorsque la radio est allumée! 
2.4.1.1  Entretien Et Remplacement De L’antenne 
MISE EN GARDE
N’utilisez  pas  la  radio  portative  si  son  antenne  est  endommagée  ou  absente.  Une 
brûlure légère peut se produire au contact d’une antenne endommagée avec la peau. 
Remplacez  immédiatement  une  antenne  endommagée.  L’utilisation  d’une  radio 
portative alors que l’antenne est absente peut causer des blessures, endommager la 
radio et pourrait enfreindre la réglementation de la FCC. 
AVERTISSEMENT
Utilisez  seulement  l’antenne  fournie  ou  une  antenne  approuvée.  Des  antennes  non 
autorisées, des modifications ou des ajouts à une antenne peuvent endommager la radio et 
enfreindre la réglementation de la FCC. (Reportez-vous à Table 6-1.) 
2.4.1.2  Appareils Électroniques 
AVERTISSEMENT
L’énergie  des  RF  provenant  de  radios  portatives  peut  affecter  certains  appareils 
électroniques.  La  majorité  de  l’équipement  électronique  moderne  dans les  voitures,  les 
hôpitaux, les maisons, etc. est blindé contre l’énergie des RF. Cependant, dans les zones 
où l’on vous demande de fermer l’équipement de radio bidirectionnelle, respectez toujours 
les règles. En cas de doute, éteignez-le! 
2.4.1.3  Avion 
MISE EN GARDE
 Éteignez toujours une radio portative avant d’embarquer à bord d’un avion! 
 Ne l’utilisez au sol qu’avec la permission de l’équipage. 
 NE l’utilisez PAS durant le vol! 
2.4.1.4  Détonateurs Électriques  
MISE EN GARDE
Pour prévenir la détonation accidentelle des détonateurs électriques, n’utilisez PAS 
de radios bidirectionnelles à moins de 305 m (1 000 pi) des opérations de détonation. 
Respectez toujours les indications « Éteindre les radios bidirectionnelles » situées là 
où des détonateurs électriques sont utilisés. (Norme OSHA : 1926.900)

2.4.1.5  Atmosphère Potentiellement Explosive 
MISE EN GARDE
Les  zones  ayant  une  atmosphère potentiellement explosive  sont  souvent, mais  pas 
toujours, identifiées clairement comme telles. Il peut s’agir de zones d’alimentation 
en  carburant,  comme  les  postes  d’essence,  les  installations  de  stockage  ou  de 
transfert  de  carburant  ou  de  produits  chimiques,  ainsi  que  les  zones  dont  l’air 
contient des produits chimiques ou des particules, comme des grains, de la poussière 
ou des poudres métalliques. 
Des étincelles dans de telles zones peuvent provoquer une explosion ou un incendie, 
causant ainsi des blessures ou même la mort. 
Éteignez  les  radios  bidirectionnelles  dans  toute  zone  ayant  une  atmosphère 
potentiellement  explosive.  Il  est  rare,  mais  pas  impossible  qu’une  radio  ou  ses 
accessoires produisent des étincelles.

3  CLEANING 
Keep the exterior of the radio, battery, antenna, and radio accessories clean.   
Periodically clean using the following procedures: 
1. To remove dust and dirt, clean using damp clean cloth (warm water and mild detergent soap). 
2. Follow by wiping with damp (warm water) clean cloth.  Wipe dry with clean cloth 
3. Remove the battery and wipe the battery and radio contacts using a soft dry cloth to remove dirt or 
grease.  This will ensure efficient power transfer from the battery to the radio. 
4. Remove any accessories and clean the accessories Universal Device Connector (UDC) contacts using 
a clean dry cloth.  When the UDC is not in use, cover the connector with the protective dust cap to 
prevent the build-up of dust or water particles. 
5. If the radio is used in a harsh environment (such as driving rain, salt fog, etc.), it may be necessary to 
periodically dry  and  clean  the  battery and  radio contacts  with a  soft dry cloth or  soft-bristle  non-
metallic brush. 
For more rigorous cleaning, use the following procedure: 
CAUTION
Do not use chemical cleaners, spray, or petroleum-based products.  They may damage 
the radio housing.  We recommend using Chemtronics® Electro-Wash® PR (ES-1603) or 
equivalent. 
1. Apply the cleaning solution to a clean damp cloth and clean the radio. 
Do not spray cleaning solution directly on radio.  To clean the radio in the speaker and 
microphone  areas,  carefully  wipe  these  areas but  prevent the  cleaning solution  from 
entering the speaker or microphone openings. 
2. Wipe off the radio with clean damp cloth using mild warm soapy water. 
3. Follow up by wiping off the radio with clean damp cloth using warm water only.

4  BATTERIES 
The XG-75P series portable radios use rechargeable, recyclable Nickel Metal Hydride (NiMH), Lithium-
Ion  (Li-Ion),  or  Lithium  Polymer  (Li-Poly)  batteries.    Please  read  the  battery  information  provided 
carefully to maximize the useful life of each type of battery. 
WARNING
Do not disassemble or modify Lithium battery packs.  Lithium battery packs are 
equipped  with  built-in  safety  and  protection  features.    Should  these  features  be 
disabled  or  tampered  with  in  any  way,  the  battery  pack  can  leak  electrolyte, 
overheat, emit smoke, burst, and/or ignite. 
If the battery is ruptured or is leaking electrolyte that results in skin or eye contact 
with the electrolyte, immediately flush the affected area with water. If the battery 
electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician 
immediately. 
4.1  CONDITIONING BATTERY PACKS 
4.1.1  Conditioning NiMH Battery Packs 
Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries 
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging 
and fully discharging the battery three (3) times using the tri-chemistry charger.  The first time the battery 
is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and 
discharging (cycling) the battery.  Refer to the appropriate charger manual for details. 
Failure  to  properly  condition  NiMH  battery  packs  before  initial  use  will  result  in 
shortened performance by the battery. 
4.1.2  Conditioning Li-Ion or Li-Poly packs 
Lithium battery packs do not suffer from memory effect and do not require conditioning.   
4.2  STORING LI-ION BATTERY PACKS 
If a battery pack is expected to be idle for a month or more, it should be properly prepared.  Li-Ion battery 
packs should not be stored fully charged.  Before storing the battery pack, discharge it to 40% capacity.  If 
the battery is not discharged prior to storage, its overall capacity may be reduced.  Although all battery 
packs experience some capacity loss  during storage, the  shelf  life  for  Li-Ion  battery  packs  is about  3 
months.  However, note that any capacity drop which occurs during storage is permanent and cannot be 
reversed. Li-Ion battery packs should be purchased and used immediately.  They should not be stock-
piled without a rotating stock plan.  
WARNING
CAUTION

  14221-1100-2010, Rev. E 
25 
4.3  CHARGING BATTERY PACKS 
Battery chargers are available from Harris with nominal charge times. Combinations include single and 
multi-position charge units.  
Harris  chargers  are  specifically  designed  for  charging  nickel-based  and  lithium  battery  packs.  The 
chargers  are  chemistry-specific  for  the  battery  packs  and  automatically  adjust  the  charging  profiles 
accordingly.  Refer to the appropriate charger manual for specific operating instructions.  
Observe the following guidelines when charging a battery pack: 
 Avoid high temperature during charging.  
 Discontinue use if the charger is overheating. 
 Only charge Harris battery packs using a charger approved for use by Harris. 
 Do not leave batteries in the charger indefinitely. For best results, leave the battery in the charger for 
two to six hours after the Green Ready LED comes on. Then place the battery pack into service and 
fully discharge (as indicated by the radio low battery warning) before re-charging. 
If any faults are encountered while charging the battery pack, consult the charger’s manual to determine 
the cause and possible corrective action. 
4.4  BATTERY PACK USAGE 
NiMH, Lithium-ion, and Lithium Polymer batteries vary in capacity and life cycle. NiMH, Lithium-Ion, 
and Lithium Polymer batteries require that basic usage guidelines be followed in order to optimize the 
battery runtime or shift life. 
The following guidelines will help optimize the battery runtime or shift life: 
 Ensure  Nickel-based  battery  packs  are  fully  discharged  (as  indicated  by  the  radio  low  battery 
warning) before re-charging.  Full discharge is not required for Lithium battery packs. 
 Periodically condition Nickel-based  battery packs.    The frequency should be  determined based on 
usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning) 
during routine use, the frequency of conditioning may be reduced.  Lithium-ion and Lithium Polymer 
batteries do not suffer from memory-effect and therefore do not require conditioning. 
Do not leave any Harris rechargeable batteries in a charger for more than a few days.

5  INTRODUCTION 
The XG-75P is available in two models: the Scan model with a limited 6-button front-mounted keypad 
and the System model with a 15-button DTMF front-mounted keypad.  The Harris XG-75P portable radio 
delivers  end-to-end  encrypted  digital  voice  and  IP  data  communications.    It  is  designed  to  support 
multiple operating modes including: 
 EDACS® (Enhanced Digital Access Communications System) or ProVoice™ Trunked Modes 
 P25 Trunked Mode 
 P25 Digital Conventional Mode 
 OpenSky® Trunked Protocol (700/800 MHz radio only) 
 Conventional Analog Mode 
The XG-75P portables can include all of these modes or just one. Additional modes of operation can be 
added with software updates. 
The  XG-75P  supports  a  full  range  of  advanced  digital  trunking  features,  including  talk  group  calls, 
priority scanning, emergency calls, late call entry, and dynamic reconfiguration. It performs autonomous 
roaming  for  wide  area  applications.  High  quality  voice  coding  and  robust  audio  components  assure 
speech clarity. 
In the trunked modes, the user selects a communications “operating” system (i.e., EDACS, ProVoice, or 
P25) and group. While communicating in a trunked mode, channel selection is transparent to the user and 
is controlled via digital communication with the system controller (e.g., a CSD in an EDACS system). 
This provides advanced programmable features and fast access to communication channels. 
In Conventional Analog mode, the user selects a channel and communicates directly on that channel.  A 
channel is a transmit/receive radio frequency pair. 
The exact  operation of the  radio will  depend on the operating mode, the radio’s  programming,  and the 
particular radio  system. Most features  described  in  this  manual can  be  enabled through programming. 
Consult your System Administrator for the particular features programmed into your XG-75P.  Then refer 
to the corresponding section(s) within this manual for feature and operation information. 
The  XG-75P series portable radios  operate  reliably even  under  adverse conditions. These  radios  meet 
MIL-STD-810G specifications for wind driven rain, humidity, and salt fog.

8.2  TRI-COLOR LED 
Figure 8-6: Tri-Color LED 
The Tri-Color LED changes color to indicate radio status and is visible from both the front and top of the 
radio (see Figure 8-6).   
In OpenSky mode the following radio states are reflected by the LED and the status they represent are:  
Green:    Receiving 
Red:    Transmitting 
Orange:  If the LED is flashing rapidly, the radio is receiving an emergency call.  If the 
LED is flashing every ½ second, the selected talk group is in the emergency state 
(although not transmitting).  If the selected talk group is in the emergency state, 
an asterisk will be displayed next to the talk group name. 
8.3  LOG IN TO THE NETWORK 
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled, 
requires the user to enter a User ID and password. 
The user will be prompted with “Pls Login” if one talk group in the selected profile can 
be encrypted. The user has to login to use that talk group in encrypted mode.  
1. Press *1 keys (Login command). 
2. Enter the full 10-digit User ID. 
3. Press the   key. 
4. Enter the password.  
5. Press the   key. 
The  User  ID  may  be  remembered  from  the  previous  log-in.  (Refer  to  Section  8.4  for  further  details 
regarding log-off commands.) The password will be established before the radio is put into operation. 
Contact the local OpenSky network administrator for more information. 
If necessary, contact radio system administration personnel for log-in assistance and/or 
radio-specific log-in instructions.

8.4  LOG OFF THE NETWORK 
The *0## command  de-registers the  radio.  Typically,  this is automatically performed when powering 
down the radio.  Using this method, the User ID is remembered by the radio, so only the password is 
needed at next log-in. If a user is logged in, it is necessary to log-off. 
8.5  PERSONALITY 
As illustrated in Figure 8-7, a personality defines the profiles and talk groups available to the user.  It is 
the structuring of a collection of profiles and privileges established by the OpenSky network administrator 
to provide the user with a comprehensive set of profiles to communicate effectively with the necessary 
talk groups or individuals. 
Personalities are stored on the network and downloaded over-the-air to the radio.  This process is called 
“provisioning.”    Provisioning  occurs  at  radio  power-up  (if  the  personality is not already stored in  the 
radio’s memory) and at user log-in (if the radio has been deregistered).  When changes are made to the 
personality, the radio is automatically re-provisioned. Each personality can contain up to 16 profiles and 
each profile can contain up to sixteen talk groups. 
8.5.1  Profiles 
As  stated  above,  each  profile  can  contain  up  to  16  talk  groups.    A  profile  also  defines  the  radio’s 
emergency behavior. All transmissions are made on the selected talk group (displayed on the top line of 
the dwell display).  The user can change the selected talk group to any of the other talk groups within the 
profile. 
Figure 8-7: Personality Structure Example 
8.5.2  Talk Groups 
A talk group represents a set of users that regularly need to communicate with one another.  There can be 
any number of authorized users assigned to a talk group. Talk groups are established and organized by the 
OpenSky network administrator.  An OpenSky talk group is similar to a channel within a conventional 
FM radio system.

8.6  OPENSKY DISPLAY OVERVIEW 
The 12-character x 3-line display shows the radio status.  The first two lines of the display are text lines 
that change in response to user interaction with the menu buttons.  Status icons appear in the bottom line 
(line 3) of the display (see Table 8-3).  
8.6.1  Display’s Top Line 
The  display’s  top  line  of  text  changes  as  the    and    buttons  are  pressed  to  scroll  through  the 
available menu options (see Table 8-5).  When the dwell display is present, the selected talk group will be 
displayed.  Other information, such as alert messages will scroll across the top line of the display. 
8.6.2  Display’s Second Line 
The second line will display information such as active menu, login prompt, emergency status, and dwell 
display messages as described in the following section.  
8.6.3  Dwell Display 
When not engaged in menu selection, the first two lines of the display default to the user-defined display, 
known as the “dwell display.”  The top line indicates the currently selected talk group.  The second line 
will display the currently selected profile, caller ID/alias2, received talk group, and current channel name 
if the channel menu is enabled.  Press the   button repeatedly to scroll through and view one of these 
second line options.  
8.7  ALERT TONES 
The  XG-75P  radio  also  provides  audible  Alert  Tones  or  “beeps”  to  indicate  the  various  operating 
conditions (see Table 8-4).

Toggles Scan Mode On/Off (Normal/Fixed, see details below) 
  If the Scan Mode is Normal when the Scan Mode is toggled Off, the Scan Mode will be Normal when 
toggled On again. 
  If the Scan Mode is Fixed when the Scan Mode is toggled Off, the Scan Mode will be Fixed when 
scan mode is toggled On again. 
  If the Scan Mode is Off when the radio boots up, the Scan Mode will be Normal when Scan Mode is 
toggled On. 
4# 
Lights/Tones On/Off 
Pressing 4# turns the TX/RX LEDs, Backlight, and Side Tones On/Off. 
If any of the TX/RX LEDs, Backlight, and/or Side Tones are On, and this quick key sequence is used, 
then all of the TX/RX LEDs, Backlight, and Side Tones are turned Off. 
If  the  radio  is  in  Stealth  mode,  this  quick  key  is  disabled  since  the  user  is  not  able  to  turn  on  the 
light/tones in stealth mode. 
5# 
This quick key sequence is used to set the current active profile to the default profile in the personality as 
defined in the UAS. 
6# 
XCOV & XCOV-TG Attach/Detach 
This  quick  key  sequence  is  used  to manually connect  to a  V-TAC.    When  attaching to a  V-TAC,  the 
radio’s programming determines whether to attach to the V-TAC in XCOV or XCOV-TG mode. 
  If the user attaches to a V-TAC manually, using the *61# or *62# command sequence, the radio is 
understood to be attached and this quick key sequence will detach the radio from the V-TAC. 
  If the user detaches manually from a V-TAC using the *60# command sequence, the radio is 
understood to be detached and this quick key sequence will attach the radio to a V-TAC. 
  At bootup, the radio is understood to be detached from a V-TAC.  If a radio automatically attaches to 
a V-TAC, the radio is still understood to be detached from a V-TAC and will attempt to attach to a V-
TAC. 
  If a radio manually attaches to a V-TAC and then is automatically detached from a V-TAC, the radio 
will attempt to attach to another V-TAC. 
7# 
This quick key sequence is used to transmit the RTT Automatic Normal Message to the console. 
8#

8.14  DUAL-TONE MULTI-FREQUENCY (SYSTEM MODEL ONLY) 
Dual-Tone  Multi-Frequency  (DTMF)  is  the  system  used  by  touch-tone  telephones.    DTMF  assigns  a 
specific tone frequency to each key so a microprocessor can easily identify its activation.  This allows for 
specific tasks such as entering a user ID and password, or selective calling. 
When a key on the DTMF keypad is pressed, the DTMF tone is played through the radio’s speaker. 
8.15  CHANGING THE ACTIVE PROFILE 
The radio can store up to 16 standard profiles, one of which is the currently active profile.  To change the 
currently active profile: 
1. Press the   or  buttons until “ProfileMenu” is displayed. 
2. Use   or    to scroll through the list of available profiles. 
3. Profile becomes active when selected for longer than 2 seconds, when the   is pressed, or when the 
menu is changed using the   or  button. Press   to activate the selected profile. 
8.16  CHANGING THE SELECTED TALK GROUP 
Each profile stored in the radio can have up to 16 talk groups.  One talk group within the currently active 
profile is set as the “selected talk group.”  To change the selected talk group, turn the Group Selection 
knob on top of the radio or use the Talk Group selection menu. 
8.17  ADJUSTING DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS 
1. Press the   or  buttons until Bright Menu is displayed. 
2. Use   or   to brighten or dim the display and button backlighting. 
8.18  STEALTH MODE  
For some users, it is important to be able to turn off the radio’s display lights and side tones, but not the 
radio  traffic.    For  example,  in  covert  operations,  lights  and  sounds  could  inadvertently  expose  an 
otherwise unobservable radio user.  For this purpose, the radio has a Stealth feature that disables the radio 
display lights, indicator lights, audible alert, and side tones.  
When Stealth Mode is on, the radio continues to scan the programmed list of talk groups and the user can 
key-up on the selected talk group. 
8.18.1  Enabling Stealth Mode 
System Model only: Quick Key combination 2# toggles Stealth Mode on and off. 
Both models:  Press the   or   buttons to scroll through menus until “StealthMenu” appears in the 
display.  To immediately activate Stealth Mode press the   or   button once.  This activates Stealth 
Mode, exits the Stealth Menu, and returns to the Dwell Display. 
The display lights, indicator lights, and side tones are disabled.  The stealth mode icon is displayed. 
8.18.2  Disabling Stealth Mode 
System  Model  only:  To  re-enable  all  lighting,  side  tones  and  exit  Stealth  Mode,  press  Quick  Key 
combination 2# again.  The radio returns to the Dwell Display. 

  14221-1100-2010, Rev. E 
47 
Stealth Mode can also be disabled by using the Stealth Menu. 
Scan Model only: To re-enable all lighting, side tones, and exit Stealth Mode, press any key other than 
PTT or Emergency.  The radio returns to the Dwell Display. 
The display lights, indicator lights, and side tones are re-enabled.  The stealth mode icon disappears. 
8.19  ADJUSTING SIDE TONE AUDIO LEVEL 
The radio sounds confirming tones called “side tones” when its buttons are pressed. Most users find this 
audible confirmation helpful when navigating the menus. Side tone audio level can be adjusted or turned 
completely off using the “Side Menu” or the Quick Key combination #4. 
Quick Key combination 4# turns off the backlight in addition to the side tones.  Unlike 
Stealth Mode, alert tones can still be heard. 
For covert operations, it may be necessary to turn off side tones.  For safety’s sake, turning off the radio 
during covert operations is not recommended. 
If the radio is operating properly but side tones are not heard when the menu buttons are pressed, the side 
tones are probably turned off.  To turn them back on, access the “Side Tone” menu and select a setting 
other than “off.” 
Use the following procedure set side tone level: 
1. Press the   or  buttons to cycle through the menu until “Side Menu” is displayed. 
2. Press   or   to change to the desired level (Off, Low, Medium, and High).  To turn side tones off 
completely, use the “Off” setting. 
8.20  CHANGE OPERATING MODE 
8.20.1  From OTP to ECP Mode 
Method 1 (Quick Key, System Model only): 
Press 1#. If ECP is not loaded in the radio, the radio displays “No App.” 
Method 2: 
1. Press the   or  buttons to cycle through the menu until “App Mode” is displayed. 
2. Press   or   to select the desired operation mode. 
3. Press   and use   or   to select Y or N.   
4. Press   to make selection and return to the dwell display. 
5. “Restart Please Wait” appears in the display as the radio switches modes. 
Method 3: 
If configured, turn the A/B Switch to the A or B position.

8.20.2  From ECP to OTP Mode 
Press  the    or   buttons  to  cycle  through  available  systems  until  “OPEN  SKY”  appears  in  the 
display.  Pause briefly and the radio will switch automatically from ECP to OTP operation. 
8.21  RECEIVING AND TRANSMITTING VOICE CALLS 
As soon as the radio completes the initialization sequence and registers on the OpenSky network, the user 
will begin to hear calls from the talk groups in the active profile, if available.  
8.21.1  Receiving a Voice Call 
No action is required to receive a voice call. The display responds to incoming voice calls as follows: 
 When the dwell display is set to received talk group and the scan mode is Normal or Fixed: 
a. If the received talk group matches the selected talk group, then the alias (if available) or user ID 
of the incoming caller is displayed.  
b. If the received talk group does not match the selected talk group, then the received talk group 
name is displayed. 
 When the  dwell  display is  set to  received  talk  group  and  the  Scan  Mode  is  None, the  radio  only 
receives voice on its selected talk group. When the call is received, the alias (if available) or the user 
ID of the incoming caller is displayed. 
 When the dwell display is not set to received talk group, then there is no display indication of an 
incoming call. 
A radio receiving a System All Call, Regency All Call, or an Agency All Call displays 
“All Call” instead of the alias. A radio not transmitting on a talk group in emergency 
status will drop all other calls to scan into an All Call. 
8.21.2  Transmitting a Voice Call 
1. Select the desired talk group.  
2. Depress and hold the PTT button, wait a couple of seconds.  If programmed by the administrator, a 
grant tone will be sounded. 
3. Begin speaking into the microphone in a normal voice.  
4. For maximum clarity, hold the radio approximately 2 inches from your mouth.  Take care not to cover 
up the microphone while speaking. 
5. Release the PTT button to terminate an outgoing voice call. 
8.22  ADJUSTING AUDIO TREBLE LEVEL 
The tone of received signals can be adjusted using the radio’s “Treble Menu.” 
1. Press the   or  buttons to cycle through the menu until “Treble Menu” is displayed. 
2. Press   or   to increase or decrease level.  There are four levels available: low, medium, medium-
high, and high. 
3. Press   or wait a few seconds to return to the dwell display.

8.23  TALK GROUP LOCK OUT 
There are two ways to focus voice communications by suppressing calls from talk groups in the active 
profile.  
 No Scan. By changing the Scanning Mode to “No Scan” only the selected talk group is scanned. 
 Lock Out. By locking out selected talk groups, background noise or chatter can be eliminated, and 
scanning resources can be focused on just those groups whose calls you wish to monitor.  
Lock out is a listening (receive) function and only blocks received calls on locked out talk 
groups.  Lock out does not affect transmit capability.  “No Scan” and “Lock Out” do not 
apply to recent emergency lock outs. 
Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice 
calls can be heard on the radio. Talk group lock out is a scan-related feature.  With lock out, one or more 
talk groups in the active profile can be temporarily disabled from being scanned.  Calls are not received 
on locked-out talk groups.  Lock out settings are not retained between profile changes. 
P1, P2, and P3 groups CANNOT be locked out.   
The  default  emergency and  emergency-capable  talk  groups  can  be  locked  out if  they are  NOT  in  an 
emergency state.  If a talk group is locked out and is subsequently changed to the currently selected talk 
group, it will automatically be unlocked by the radio so the user can hear calls on the talk group.  The 
radio may be configured so all talk groups are automatically locked out by default.  In this case, they must 
be manually unlocked, if desired. 
8.23.1  Lock Out a Talk Group 
1. Use the   or  buttons to scroll through the menu choices until “LockOutMenu” appears in the 
display. 
2. Use the   or   keys to scroll through the list of talk groups, if any, until the user group you want to 
lock out appears in the display.  
3. Press the   key to select the lockable talk group. 
4. “<” appears next to the locked out talk group. 
8.23.2  Unlock a Talk Group 
1. Use the   or  buttons to scroll through the menu choices until “LockOutMenu” appears in the 
display. 
2. Use the   or   keys to scroll through the list of talk groups, if any, until the user group you want to 
unlock appears in the display. 
3. Use the   key to unlock the displayed talk group. 
 Changing the active profile removes any lockouts you have made. 
 Turning off the radio removes any lockouts you have made.

8.24  SCANNING 
8.24.1  Selecting Scan Modes 
Three scanning modes are available for the radio, but only one can be active at any time.  Changing the 
scanning mode changes the way the radio scans voice calls for all of the profiles in the radio personality, 
no matter which profile is or becomes active. 
The choice of scanning mode broadens or narrows the span of communications with all the groups in 
profiles you listen to, but does not affect your interaction with those groups you talk with. The scanning 
modes available for selection may be limited to a subset of the three scanning modes by the administrator. 
Table 8-8: Scan Modes 
SCAN 
MODE 
EXPLANATION 
None 
Eliminates distractions.  
Full communications (listen and talk) with the selected talk group. 
No calls received from other talk groups. 
Normal 
(Default) 
The user can scan all talk groups in the active profile that are not locked out as long as there is demand on 
the site. 
Priority (P1, P2, and P3) groups are user selectable. 
Receive calls from more than one talk group, if available from the current site. 
Allows dragging of the selected talk group, P1, P2, P3, and emergency talk group (in emergency state) to the 
site on which the radio is registered. (If other calls are available at the site, they also can be heard but they will 
not be actively dragged.) 
The default emergency talk group, as well as any emergency-enabled talk groups, is only dragged if it is in 
emergency mode. 
Fixed 
Functions the same as Normal Scan Mode, except the priority groups are fixed to the selected profile’s pre-
defined P1 and P2 groups (configured via the UAS).  
The scanning mode choice remains in effect until it is changed.  Even if the radio is turned off, the current 
scanning mode selection is saved for the next use. 
8.24.2  Changing Active Scan Mode 
8.24.2.1  Setting the Scan Mode 
1. Press the   or  buttons until “ScnModeMenu” appears in the display. 
2. Use the   or   keys to scroll through the list of modes until your choice appears: Normal, None, or 
Fixed. 
3. Press the   key to activate the scan mode selection and return to the dwell display. 
8.24.2.2  Duration of Scanning Mode Selections 
Scanning Mode selections survive power down. At startup, the radio defaults to the scanning mode of set 
during last use.  The last selection made remains in effect until a new selection is made from the Scan 
Mode menu. 
8.24.3  Scanning Priority 
The following lists the scanning priority order (from highest to lowest): 
 Selected talk group in emergency state. 

  14221-1100-2010, Rev. E 
51 
 Default emergency group in emergency state. 
 Selected talk group.

8.24.3.1  Changing Scan Priority 
1. Press the   or  keys until “Priority1” or “Priority2” appears in the display (Priority1 group has 
higher priority than the Priority2 group). 
2. Press the   or   button until the desired talk group is displayed. 
3. Press the   key to select and activate the selection.  The radio automatically returns to the Dwell 
Display. 
 Changing the priority of a listen group does not change your talk group. 
 Priority can be set for six talk groups (Priority1, Priority2, and up to four Priority 3), 
but only in the selected profile. 
 If  the  save  settings  is  configured  for  the  radio,  scanning  priority  settings  are  saved 
when the radio is turned off. Otherwise, they are reset to the default values when the 
radio is turned off. 
8.24.3.2  Changing Scan Priority 3 Talk Groups 
1. Use  the    or  buttons  to  scroll  through  the  menu  choices  until  “Priority  3”  appears  in  the

8.25  MAKING SELECTIVE CALLS  
Selective calling is the capability for two voice radio units to obtain and use an independent talk path for a 
unit-to-unit call. A properly equipped radio can initiate a selective call to any radio in the system that is 
also programmed for selective calls. 
In the OpenSky system, a radio can be configured to initiate selective calls through a pre-programmed list 
in memory called a speed dial list.  Alternatively, a properly equipped radio can initiate a selective call to 
any radio in the system by entering the ten-digit User ID (similar to a telephone number) of the target 
radio.  Some radios are configured to only receive (not initiate) selective calls. 
Selective calls are terminated if an emergency is declared.  The network limits selective 
calls to ten (10) minutes maximum. 
If a Selective Call is attempted without registration, “No Priv” is displayed. 
8.25.1  Manually Dialing a Selective Call (System Model Only) 
1. Enter *8, the User ID number of the user being called, and the # key (no dashes or spaces).  This 
feature must be enabled by the administrator.   
*8<destination user id># 
A shortened User ID number can be dialed using the following guidelines: 
 If the radio being called is in the same region and agency – enter only the last four digits. 
 If the radio being called is in the same region, but a different agency – enter only the last seven 
digits. 
 If the radio being called is in another region or if the area is unknown – enter all ten digits. 
2. Press the PTT (and release) to ring the other user. 
The ring tone is sounded. 
If the other user accepts the call, the called user’s alias will appear in initiating caller’s display.  The 
two are now in a unit-to-unit call until one ends the call, the call is terminated due to an initiated 
emergency, or the maximum time limit of ten (10) minutes is reached. 
If the called radio is busy, “BUSY” will appear in the second line of the display. 
Table 8-9 lists and defines the messages that are displayed by the radio during a selective call.

8.26  SELECTIVE ALERTS 
Selective alert messaging is an OTP feature that allows one of up to eight (8) pre-programmed (canned) 
text messages to be sent from one radio to another. The sender specifies a destination (receiving) radio, 
selects one  of  the pre-programmed  text  messages,  and  then  transmits  it  to  the  destination  radio.    The 
message  delivery  system  adds  sender  and  time-of-day  information  and  forwards  the  message  to  the 
destination  (receiving)  radio.    The  sending  radio  receives  a  brief  message  noting  the  status  of  the 
transmission.  
Received messages are stored in the radio until deleted or until the radio is rebooted.  Received messages 
do not survive a reboot. 
8.26.1  Defining Messages 
All selective alert messages are pre-defined. The messages are programmed and provisioned remotely by 
your OpenSky system administrator. The radio user cannot create selective alert message content.  The 
entire selective alert message, including the abbreviation, can be up to 99 characters long. 
Table 8-10 lists and defines the messages that may be displayed by the radio during a Selective Alert.

8.28  EMERGENCY COMMUNICATIONS 
The XG-75P portable radio is capable of sending an emergency alert and making emergency calls on the 
network.  The OpenSky system handles emergency calls with the highest priority, allowing you or the 
people you serve to get needed help.  
Emergency call and alert capability for a profile is configured by the system administrator. 
The radio that initiates an emergency alert emits a signal of three distinct beeps that only 
goes to the dispatch console.  
Table 8-11: Emergency Calls vs. Emergency Alerts 
EMERGENCY ALERT 
EMERGENCY CALL 
An  Emergency  Alert  message  is  sent  to 
the  dispatcher  console.    The  dispatch 
console plays an emergency tone  when it 
receives the message. 
An Emergency Alert message is sent to the dispatcher console.  All peers 
(radios  and  consoles)  and  the  dispatch  console  play  the  emergency  tone 
whenever an emergency call is detected.  An emergency tone plays for each 
new  emergency,  or  when  a  profile  is  changed,  (assuming  there  is  an 
emergency on one of the talk groups for the new profile). 
If  the orange  LED  is flashing  rapidly,  the  radio  is  receiving  an  emergency 
call.  If the LED is flashing every ½ second, the selected talk group is in the 
emergency state (although not transmitting).  If the selected talk group is in 
the emergency state, an asterisk displays next to the talk group name. 
No  emergency  audio  (voice)  transmission 
(hot-mic)  capability  available  (per 
programming by system administrator) 
In  addition  to  the  Emergency  Alert  signal,  the  microphone  goes  hot  for  a 
predetermined  length  of  time  to  allow  for  emergency  audio  (voice) 
transmission.    The  radio  declaring  the  emergency  has  channel  access 
priority.    The  User  can  also  use the  PTT  after  the  pre-determined  hot-mic 
audio transmission, or during to extend the initial hot-mic audio transmission.

administrator.    This  determines  whether  pressing  the  Emergency  button  sends  an 
Emergency Call or just an Emergency Alert.  An Emergency Alert is always part of and 
sent with an Emergency Call. 
If the active profile of the unit initiating the emergency is configured to Emergency Alert, the three-
beep emergency alert signal is sent only to the dispatcher console.  
If the active profile of the unit initiating the emergency is configured to Emergency Call, the three-
beep emergency alert signal is sent to the dispatcher console and to all other radios within the selected 
talk group.   The default emergency talk group becomes the  selected talk group.   The  display will 
alternate  between  the  emergency  talk  group  name  and  “EMERGENCY”  to  indicate  that  the 
emergency has been initiated. 
2. The microphone is hot (open mic) for a programmed amount of time in order to send your voice out 
on the emergency talk group. 
If the attempt is unsuccessful, “E-PEND”  flashes  periodically  and  a retry is queued for 10 seconds. If 
unsuccessful because of lost sync, retry occurs immediately upon reacquiring sync. On each retry attempt, 
the  radio  temporarily  displays  “E-RETRY.”  This  process  repeats  until  the  emergency  is  successfully 
declared. 
8.28.2  Receiving an Emergency Call 
When receiving an emergency call, the radio sounds the emergency tone (three short high-pitched tones). 
The radio will flash “EMERGENCY” and display the alias of the user that triggered the emergency or the 
alias of the talk group (if the incoming talk group is the selected talk group of the receiving radio). 
With “No Scan,” only the emergency tone is heard, not the initial open mic transmission. 
To dismiss or ignore the emergency, refer to Section 8.28.3. 
8.28.3  Dismissing an Emergency 
The “Dismissing an Emergency” function allows you to “ignore” an emergency declared by another user. 
An emergency is dismissed for a configurable amount of time (default = 5 minutes). 
1. After receiving an emergency call, press the   or  button until you see “EmgDismiss.” 
2. Press the   to toggle “<” on (dismiss) and off. This works in similar fashion to the lock out menu. 
The emergency dismiss timer is cleared when the emergency is cleared.

8.28.4  Clearing an Emergency Call or Alert 
Check with your system administrator to  ensure  that  your  radio  is  configured with  the 
ability to clear an emergency. 
1. To clear an emergency, press and hold  .  While holding  , press the emergency button.  Release 
both buttons when the “emergency cleared” tone sounds. 
2. The radio returns to your default selected talk group.  The “EMERGENCY” display is removed from 
the main screen. 
If the radio is in stealth mode, clearing the emergency will cause the radio to exit stealth 
mode.  
8.29  OPENSKY ENCRYPTION 
In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published 
by  the  Federal  Information  Processing  Service  (FIPS),  called  Advanced  Encryption  Standard  (AES).  
AES is approved by the U.S. Department of Commerce for encryption of classified materials. 
When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System 
(MES) (e.g., XG-75P portable radio).  This form of encryption provides airlink security. 
Voice encryption is handled either automatically or manually.  Automatic encryption is initiated through 
the Unified Administration Server (UAS) for a specific talk group and requires nothing from the radio 
user.    Manual  encryption  is  initiated  by  two  or  more  radio  users.    Both  methods  of  encryption  are 
discussed in the following sections. 
When a user transmits encrypted voice, any listening users with different encryption keys 
hear distorted voice and “No Access” appears in the radio display. 
8.29.1  Automatic Encryption 
For automatic encryption, a system administrator will select the talk group to be encrypted at the interface 
to  the  UAS.    Once  the  talk  groups  have  been  selected  and  identified  as  secure,  credentials  for  key 
generation are generated automatically by the system and provisioned to authorized users.  This process 
requires that  authorized  users  login  to  the  network and  be  authenticated.   Encryption  keys require  no 
manual handling and are never sent “in the clear” over any network interface or airlink. 
1. Locate the talk group that has been encrypted at the system administrator level. 
2. “Pls Login” appears in the display (unless the keypad was used to log in). 
3. Log in normally by entering your User ID and Password. 
If a user is engaged in a call on a talk group encrypted at the network administrator level, “Secure Call” 
will appear in the second line of the dwell display if the user is logged into that talk group. 
If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display 
will alternate between “No Access” and the alias of the radio that is currently engaged in the secure call.

If enabled via programming, a radio can automatically login at voice registration and enable 
voice encryption. 
8.29.2  A/B Switch 
If configured, the A/B switch can be used to enable or disable encryption. 
8.29.3  Manual Encryption (System Model Only) 
Two or more users can manually encrypt a call, if enabled, without an established encrypted talk group.  
A pre-determined “key or code” is required.  While a user is engaged in a manually encrypted call, users 
within the talk group that are not encrypted can still make standard voice calls on that talk group.  The 
encrypted  user  can  hear  the  standard  unencrypted  calls,  but  cannot  respond  while  still  manually 
encrypted. 
Manual key entry only  affects the currently selected talk group.    All  available  talk groups  within the 
current profile may be independently encrypted.   
The key must be pre-determined by the users prior to making a manually encrypted call on 
a talk group and is entered into the radio using the keypad.  For 128 bit encryption, this 
key is between 1 and 16 digits.  For 256 bit encryption, this key is between 17 and 32 
digits. 
8.29.3.1  Using Manual Encryption 
1. Press *32 on the keypad. 
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption). 
3. Press #. 
4. To end manual encryption, press *33. 
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, the user 
will see “Secure Call” on the bottom of the dwell display. 
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell 
display  will  alternate  between  “No  Access”  and  the  alias  of  the  radio  that  is  currently  engaged in the 
secure call. 
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of 
the dwell display. 
8.30  STATUS MESSAGES 
If enabled  via  programming,  the  radio  can  transmit  a  pre-programmed status  message.  Section  8.30.1

8.32  SITE LOCK 
Users may need to select the site in cases where network communications are down.  The Site Lock menu 
allows a user to manually roam to a specific site.  The sites in the menu are populated with the current 
site, adjacent sites, and node 2 sites.  The menu allows the user to select a particular site based on the Site 
Name.  Once selected, the radio will randomly pick a channel at the site that is identified as operational 
and attempt to attach to it.    
If the channel is not available, the radio attempts to attach to the next channel in the channel list for the 
site until it has attempted every channel at the site.  If no channels are available, the radio plays a “Site 
Not Found” tone and displays “SiteUnavail” on the second line of the Site Lock menu.  The radio reverts 
to its normal roaming functionality.  
If the radio does find a valid channel on the  site,  it  attaches to  it,  plays  a  “Site  Found”  tone,  displays 
“SiteAvail” on the second line of the Site Lock menu for 2 seconds, and then reverts to the Dwell menu  
8.33  GPS COORDINATES 
The  radio’s  current  latitude  and  longitude  coordinates  may  be  displayed  using  the  “GPS”  menu.    The 
following procedure assumes a GPS antenna is connected to the radio and it is receiving adequate signals 
from GPS satellites. 
1. Press   or  until the “GPS” menu appears in the display.  Current GPS coordinate latitude and 
longitude data continuously scrolls in the top line of the display in a degrees:minutes:seconds format. 
2. Press   or  to change to another menu. 
If  the  internal  GPS  receiver’s  data  is  expired  (30  minutes  or  more)  or  unavailable,  the 
radio  uses  the  serving  base  station’s  coordinates  [GPS  (Site)  is  displayed].    The  GPS 
Menu will also indicate if the data is aged (2 minutes or more) [GPS (Aged) is displayed]. 
8.34  V-TAC OPERATION 
8.34.1  Extended Coverage Modes (XCOV, XCOV-TG, and XCOV-PROF) 
In addition to all standard portable radio operating capabilities, Extended Coverage adds the V-TAC’s 
bridging (vehicular repeat) functionality for accessing the OpenSky radio network. Each portable radio 
connected to  the  V-TAC  using  Extended  Coverage  is  considered  a  “client”  on  the  V-TAC.  Extended 
Coverage  benefits  portable  radio  users  since  it  allows  them  to  get  network  connectivity  using  the 
V-TAC’s higher transmit output power and better antenna system.  
The V-TAC supports three Extended Coverage modes: Extended Coverage for individual users (XCOV), 
Extended  Coverage  for  a  talk  group  (XCOV-TG),  and  Profile  Extended  Coverage  (XCOV-PROF). 
Typically, Extended Coverage is used after the vehicle’s operator has exited the vehicle with a portable 
radio unit and the portable unit requires this bridging functionality to access the OpenSky radio network.  
The V-TAC takes advantage of OpenSky’s TDMA capability to eliminate interference between its local 
and network radio links when operating in an Extended Coverage mode, an undesirable characteristic of 
many traditional vehicular repeater systems. Because the V-TAC employs this technology, interference 
on the network and local radio links is minimized.  
A V-TAC in Extended Coverage mode sends its alias to clients. The alias is displayed in the second line 
of  the  dwell  menu  of  the  client,  (“VA  <alias>”).  The  client  must  be  connected  to  a  V-TAC  running 
NOTE

14221-1100-2010, Rev. E   
62 
version OTP14.4 or later for the V-TAC to provide the alias to the client. If the client is connected to a V-
TAC running version OTP14.3.1 or earlier, the client displays “VA None.” 
8.34.2  Change Between Extended Coverage Modes  
By default, the specific Extended Coverage mode utilized is determined by settings programmed into the 
V-TAC  and  portable  radios  from  the  system  administrator  or  radio  installation  personnel.  These 
programmed settings determine which Extended Coverage mode the V-TAC and radios normally use and 
determine the access method employed by a portable radio to connect to the V-TAC. After these settings 
are programmed to the V-TAC and portable radios, each must be rebooted (powered off and then back 
on) before the change takes effect.  
See the following sections for instructions on how to override this setting manually. The override is only 
successful if the V-TAC operating mode matches the manually selected portable V-TAC mode. 
8.34.3  Radio Limitations Using Extended Coverage Modes 
Connecting  a  portable  radio  to  a  V-TAC  introduces  minor  functional  limitations.    See  the  following 
sections for a listing. 
8.34.3.1  Limitations Using XCOV, XCOV-TG, and XCOV-PROF 
Portable radios connected to the V-TAC using any of the Extended Coverage Modes, XCOV, XCOV-TG, 
or XCOV-PROF, will  not  channel-scan unless they  lose  radio  frequency contact with the V-TAC.    If 
manually enabled, radios will not scan network channels. 
8.34.3.2  Limitations Using XCOV-TG 
The following portable radio keypad functions are disabled when the radio is connected to the V-TAC 
using  the  XCOV-TG  mode:  log-off,  manual  log-in,  alerts,  selective  calls,  PSTN calls,  and  speed  dial 
calls, SOI mode, RTT.  
The following portable radio menus are disabled when the radio is connected to the V-TAC using the 
XCOV-TG  mode:  alert  destination,  alert  message,  alert  received,  channel,  speed  dial,  priority  1  talk 
group, priority 2 talk group, priority 3 talk group, RTT, Status message, site lock and scan mode.  In 
addition, the user cannot change talk group or profile. 
8.34.3.3  Limitations Using XCOV-PROF 
The following portable radio keypad functions are disabled when the radio is connected to the V-TAC 
using the XCOV-PROF mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and speed dial 
calls, SOI mode, RTT.  
The following portable radio menus are disabled when the radio is connected to the V-TAC using the 
XCOV-TG mode: alert  destination,  alert  message, alert received, priority  1  talk group,  priority  2  talk 
group, priority 3 talk group and scan mode.  In addition, the user cannot change talk group or profile. 
8.34.4  Use XCOV Mode  
The Extended Coverage for individual users (XCOV) mode allows up to eight (8) client radios to connect 
to the V-TAC.  The radios have full radio functionality including selective calling and mobile data.  
With the Extended Coverage for  individual users’ (XCOV) mode,  V-TAC configuration defines which 
portable  radios  are  permitted  V-TAC  access.    The  radio  will  automatically  connect  to  a  V-TAC  if  it 
cannot find a network channel.  The radio can also be manually connected to a V-TAC as indicated with 
the *61# and *62# commands, each determined by the system administrator in the radio configuration.

8.34.4.1  Manually Accessing the XCOV Mode 
System Model Radios 
1. Press *61# to manually access XCOV mode.  
2. Press *60# to manually disconnect from XCOV mode.  
Both Model Radios 
1. Press   or   until the Client Mode menu appears. 
2. Press   or   until XCOV is displayed. 
3. Press   to confirm mode selection.  The radio reverts to the dwell display and the V-TAC icon is 
displayed. 
8.34.5  Use XCOV-TG Mode  
When using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC.  However, 
unlike XCOV, radios connected using XCOV-TG are limited to communicating only on the XCOV-TG 
talk group.  The radio can only raise an emergency if this talk group is emergency capable. Advanced 
features such as selective calling and mobile data operations are not available to the XCOV-TG connected 
clients.  The radio will automatically connect to a V-TAC if it cannot find a network channel. 
The talk group used for XCOV-TG communications is the talk group that was selected at the V-TAC 
when it entered XCOV-TG mode.  Before a radio can connect to the V-TAC, the talk group must be 
selected on the radio.    If  this  talk  group  is  not  provisioned  in  the  radio’s personality,  the  radio  cannot 
connect  to  the  V-TAC  via  the  XCOV-TG  mode.    While  connected  to  the  V-TAC  via  XCOV-TG,  a 
different talk group or profile cannot be selected.  
When a portable radio is connected to the V-TAC via XCOV-TG, the V-TAC forwards only the network 
voice traffic on the XCOV-TG talk groups.   
8.34.5.1  Manually Accessing the XCOV-TG Mode 
For the Extended Coverage for a talk group mode (XCOV-TG), a portable radio user is granted access 
and connects to the V-TAC by simply selecting the same Talk Group that the V-TAC had selected when 
it entered the XCOV-TG mode.  Contact the system administrator for questions regarding these aspects. 
During XCOV-TG mode operations, the V-TAC will not disconnect portable radios connected to it.  A 
portable radio user must manually disconnect from the V-TAC by pressing *60 # on the radio’s keypad.  
However, if the V-TAC is switched out of the XCOV-TG mode, all portable radios will be automatically 
disconnected  from  the  V-TAC.    The  radios  will  continue  to  look  for  another  V-TAC  until  manually 
disconnected (*60#).  
System Model Radios 
 Press *62# to manually access XCOV-TG mode.  
 Press *60# to manually disconnect XCOV-TG mode. 
Both Model Radios 
1. Press   or   until the Client Mode menu appears. 
2. Press   or   until XCOV-TG is displayed. 
3. Press   to confirm mode selection.  The radio reverts to the dwell display and the V-TAC icon is 
displayed.

8.34.6  Using XCOV-PROF Mode 
In  XCOV-PROF  mode,  client  attachment  to  a  V-TAC  is  based  on  profile  rather  than  talk  group. 
XCOV-PROF mode allows the transmission and receipt of voice calls on any talk group in the profile as 
opposed to only one talk group. XCOV-PROF allows emergencies on a non-selected talk group based on 
the emergency behaviors of the profile. XCOV-PROF minimizes data traffic between the client and V-
TAC while allowing flexibility of voice functionality. As a result, data services between the client and V-
TAC are disabled. The radio will automatically connect to a V-TAC if it cannot find a network channel. 
Note the following regarding XCOV-PROF mode: 
 The client profile must match the V-TAC.  
 The client profile used to connect to the V-TAC must have been previously provisioned to the client 
prior to connection. If the profile is not in the client’s personality, the client cannot connect to the V-
TAC. 
 Neither the V-TAC nor a client can change the profile once it has entered XCOV-PROF mode. The 
Profile menu will be disabled. 
 Client global profiles are disabled. 
8.34.6.1  Access XCOV-PROF Mode 
System Model Radios Only: 
 Enter the command *63 # to set the radio to use the XCOV-PROF mode. 
 Press *60 # to disconnect from the XCOV-PROF mode. 
Both Model Radios: 
1. Press   or   until the Client Mode menu appears. 
2. Press   or   until XCOV-PROF is displayed. 
3. Press   to confirm mode selection. The radio reverts to the dwell display and the V-TAC icon is 
displayed. 
8.34.7  Use Scene-of-Incident Mode 
The Scene-of-Incident mode (SOI) is user-selectable.  The SOI mode provides a local repeater function 
(V-TAC) with no network connection. 
When operating in the SOI mode, the radio is disconnected from the OpenSky network.  
Therefore,  communications  with  radios  and  dispatch  personnel  on  the  network  is  not 
possible. 
SOI Mode, Manual Channel Entry (System Model Only) 
1. Press *4#. 
2. The radio prompts for the channel.  Enter the channel number and press   to confirm channel. 
3. The radio prompts for the band. Table 8-12 lists valid bands and their definitions. Enter the number 
assigned for the desired frequency band and press   to confirm. 
4. The radio reverts to the dwell display.   If accepted, you will be switched off the network, and be 
communicating locally through the V-TAC.

to operate the radio. Check with your System Administrator if you 
forget your PIN. As the PIN is entered, an asterisk is displayed for 
each digit.  The actual value is not displayed. 
Rotating  the  control  clockwise  applies  power  to  the  radio.    If  enabled  through 
programming, a single alert tone indicates the radio is operational. 
Rotating the control clockwise increases the volume level.  A minimum volume 
level  can  be  programmed  into  the  radio  to  prevent  missed  calls  due  to  a  low 
volume setting.  While adjusting the volume, the display momentarily indicates the 
volume level (i.e., VOL=31).  The volume ranges from a minimum programmable 
level of zero (displayed as OFF in the display) up to 40, which is the loudest level.

9.5  UNIVERSAL DEVICE CONNECTOR 
The Universal Device Connector (UDC) provides connections for external accessories such as a headset, 
a speaker-microphone, audio test box, audio test cables, and programming cables.  The UDC is located on 
the right side of the radio, opposite the PTT Button.  The UDC facilitates programming and testing the 
radio.  The UDC pins perform different functions depending on the accessory attached to the UDC.   
Figure 9-7: XG-75P 15-Pin Universal Device Connector 
9.6  NOISE CANCELLATION 
The XG-75P features  Harris’  proprietary  noise  suppression  capability  to  provide  clear  and  crisp  voice 
quality  in  high-noise  environments  for  use  in  any  mode,  including  both  analog  and  digital 
communications.  
The XG-75P has two microphones; one located on the front (primary) and one on the rear (secondary). 
The primary microphone operates in exactly the same manner as a normal radio and is the one you talk 
into.  The  secondary  microphone  is  used  to  pick  up  the  surrounding  noise  when  noise  cancellation  is 
turned on.  
In the case where noise cancellation is enabled and a speaker microphone is attached to the XG-75P, talk 
into the speaker microphone. In this mode, XG-75P front microphone is used to pick up the surrounding 
noise, and the rear microphone is unused.  
If the secondary microphone is blocked, the XG-75P operates as though noise cancellation is turned off.  
9.6.1  Turning Noise Cancellation On and Off 
A button on the radio or the A/B switch can be programmed to toggle noise cancellation on or off. 
OR 
1. Press the   button. 
2. Use the   or   button to select “NOIS CAN.” 
3. Press the   again to toggle noise cancellation on or off.  
The  top  line  of  the  display  will  briefly  display  “NC  ON”  or  “NC OFF.”  When  noise  cancellation  is 
enabled, the   icon is displayed on the bottom of the display. 

  14221-1100-2010, Rev. E 
73 
9.6.2  Using Noise Cancellation 
When using the noise cancellation feature, observe the following: 
 Talk within two (2) inches of primary microphone (see Figure 9-8). 
 Speak clearly, loudly, and with authority.  
 If possible, face the noise source when talking into the radio (see Figure 9-8). 
 Ensure  the  primary  and  secondary  microphones  are  not  covered.  See  Section  9.6.4  for  more 
information on the primary and secondary microphones. 
 In very noisy environments, it is okay to yell into the radio. The radio can handle very loud input 
levels. 
Figure 9-8: Using the Noise Cancellation Feature 
9.6.3  The Effect of Distance from the Microphone 
Unlike a normal microphone system, noise cancellation makes the level of your voice diminish quickly as 
you  move  away  from  the  radio.  In  essence,  the  radio  starts  to  see  your  voice  as  surrounding  noise. 
Whereas, you may be comfortable speaking up to a foot away from the front of a normal radio, noise 
cancellation requires that you keep it close. 
9.6.4  Primary versus Secondary Microphone 
9.6.4.1  Without a Speaker Microphone Attached 
The primary microphone is located on the front of the radio and the secondary is on the back of the radio.  
9.6.4.2  With a Speaker Microphone Attached 
When  a  speaker  microphone is  attached, the radio electronically  switches  over  to  use  the  radio’s  front 
microphone  as  secondary.  The  microphone  on  the  attached  speaker  microphone  becomes  the  primary 
microphone.

being  received  is  an  encrypted  transmission,  it  will  be  decrypted,  the    icon  will  be  displayed,  the 
receiver will unsquelch, and the message will be heard in the speaker.  For this to occur, the selected 
group or channel must be programmed for private operation and the correct cryptographic key must be 
loaded into the radio. 
9.20.4 Transmitting an Encrypted Call 
1. Select the desired group or channel. 
2. Place the radio in Private Mode by pressing   key, then select PRIVATE from the menu. On a 
System radio, the   key can be  used to toggle the Private Mode  on/off. When Private Mode is 
enabled, the   icon is displayed.

3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also, 
the Private Mode will be enabled if forced operation has been programmed in the radio.  
If a group or channel is not programmed for Private Mode operation, PVT DIS will be displayed if 
an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel 
in Private Mode.  
If the radio does not have the correct encryption key loaded, NOKY will be displayed and the call will 
not be transmitted. 
4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the 
PTT button is pressed. 
9.21  SCANNING TRUNKED GROUPS 
Groups that have been previously added to the scan list on a per system basis may be scanned.  Each 
system's group scan list is retained in memory when the radio is powered off or when the battery pack is 
removed.  
9.21.1 Turning Scan On and Off 
1. Toggle  Scan  operation  on  by  pressing    (Scan  model)  or   (System  model).   icon  rotates 
clockwise to indicate radio is scanning.  
2. Toggle  Scan  operation  off  by  again  pressing    (Scan  model)  or   (System  model).    will 
disappear.  
 If the radio scans to a group other than the selected group then receives a call on the selected 
group,  the  radio  will  switch  to  the  selected  group.  However,  if  the  “scanned-to”  group  is 
programmed at a higher priority the radio will remain on the “scanned-to” group. 
 The radio will continue scanning if a new group is selected when scan is on.  
3. Pressing the PTT button when scan is on will cause the radio to transmit on the displayed group or to 
the currently selected group (depending on programming). 
9.21.2 Adding Groups to a Scan List 
Scan Model Radio 
1. Scan must be off to add/delete groups to/from the scan list. If the Scan icon   is on, press the   
key to turn Scan off.  
2. Select the desired group using the System/Group/Channel control knob and/or the   or  keys. 
If the selected group is currently on the list, pressing   will display   on line three.  
3. If the scan list status icon is blank, the group can be added to the scan list by pressing the   key.   
will be displayed on line three. 
4. Press the   key a second time to set the group to Priority 2. A   is displayed on line three.

A group can also be deleted from the scan list, if it is not the currently selected group, by pressing the 
 key (Scan model) or the   key (System model) during scan operation while the radio is displaying 
the unwanted group. The group will be deleted from the system's group scan list in the same manner as if 
done using the steps above. Deletions done in this manner will not remain deleted if the radio is powered 
off and then powered on. 
9.22  SCANNING TRUNKED SYSTEMS 
The radio can be programmed using Radio Personality Manager (RPM) with the following System Scan 
features. Then these features are automatically enabled when the radio is powered  on. A key or menu 
option is also defined to allow the System Scan features to be toggled during radio operation. The System 
Scan state will be maintained through system changes but will default to on when the radio is powered on. 
Enable/Disable via Menu Selection 
Press    and  then  use  the    or  buttons to  scroll  through the  selections until  SYS  SCAN  is 
displayed.  Then  press    to  toggle  the  System  Scan  state.  The  SYSC  ON  or  SYSC  OFF  display 
message is displayed for two seconds to show the new state. 
Enable/Disable via Pre-Programmed Keypad Key 
Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message 
is displayed for two seconds to show the new state. 
9.22.1 Wide Area System Scanning 
The XG-75P series radio can be pre-programmed through RPM for Wide Area System Scan operation for 
roaming across mobile systems.  EDACS radio systems manage the radios assigned to the system via a 
control channel (CC).  Upon the loss of the currently selected system's control channel, radios can  be 
programmed  to  automatically scan  the  control  channels  of  other  systems. If  a  new  control  channel  is 
found, the radio will switch to the new system and sound an alert tone. 
9.22.2 Priority System Scan 
The radio can also be pre-programmed for Priority System Scan.  The priority system is the desired or 
preferred system.  While receiving the control channel of the selected system, the radio will periodically 
leave the selected system and search for the control channel of the priority system.  This is done at a pre-
programmed rate defined by the value in the Priority Scan Time control, unless the ProScan™ algorithm is 
enabled, as explained in the following sections.  This priority scan timer is reset each time the PTT button 

  14221-1100-2010, Rev. E 
85 
is  pressed  or  when  the  call is  received.    If the  priority system control channel is  found,  or  meets  the 
predefined criteria (ProScan), the radio will automatically switch to the priority system. 
9.22.2.1  Enabling the Wide Area System Scan Function 
If the radio cannot find the control channel of the selected system and begins to wide area system scan, 
the radio will only scan for the priority system control channel if the priority system is in the wide area 
scan list. 
9.22.2.2  When ProScan is Enabled 
The radio monitors the  priority  system and  will  switch  to  the  priority system if  the  pre-preogrammed 
criteria ProScan options are met.   If ProScan is enabled, the rate at  which the radio will  scan  for the 
priority system is defined by the System Sample Time control, set in RPM (refer to RPM On-Line Help).  
See Section 9.22.3 for more information on ProScan. 
9.22.3 ProScan 
The radio may be programmed for ProScan system scan operation for multi-site applications.  ProScan is 
a  multi-site,  system-scanning  algorithm.    ProScan  provides  the  radio  with  the  ability  to  select  a  new 
system for the radio to communicate on, when the selected system drops below a predefined level.  This 
algorithm enables each radio to analyze the signal quality of its current control channel and compare it 
with the signal quality of the control channel for each site in its adjacent scan list.  The signal quality 
metric  used  for  the  ProScan  algorithm  is  based  on  a  combination  of  both  Received  Signal  Strength 
Indicator  (RSSI)  and  Control  Channel  Verification  (CCV)  measurements.    When  the  selected  system 
degrades to a pre-programmed level, the radio will begin to look for a better control channel.  Once a 
control channel that exceeds the pre-programmed parameters is found, the radio will change to the new 
system and emit a tone (if enabled through programming).  If the control channel is completely lost, the 
radio will enter Wide Area System scanning and search the programmed adjacent systems until a suitable 
control channel is found. 
9.23  EMERGENCY OPERATION 
The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency system 
and  group,  and  the  emergency  audio  and  display  freeze  can  each  be  enabled  or  disabled  through 
programming.  When an emergency is declared, scanning will stop and restarts only after the emergency 
has been cleared. 
9.23.1 Receiving an Emergency Call 
When receiving an Emergency Call on the selected group and system, an alert beep is heard and   is 
displayed. The message *RXEMER* flashes in the display on line two until the emergency condition is 
cleared. 
9.23.2 Declaring an Emergency Call 
Perform the following steps to send an emergency call to a selected system and group (or on an optionally 
pre-programmed group).  
1. Press and hold the red EMERGENCY button that is on top of the radio in front of the antenna for 
approximately one second (this time is programmable and therefore could be longer or shorter; check 
with the system administrator). The radio will transmit an emergency call request with the radio ID 
until an emergency channel assignment is received.  

14221-1100-2010, Rev. E   
86 
2. When the working channel assignment is received, the radio sounds a single beep indicating the radio 
has auto keyed (see Table 9-4) and is ready for voice transmission. *TXEMER* flashes on line two in 
the display until the emergency is cleared.  
3. Press PTT and speak into the microphone in a normal voice.   and   momentarily turn on.  
4. Release PTT when the transmission is complete.  
To clear the emergency, first press and hold the   button. While continuing to hold the   button, press 
the EMERGENCY button. The radio must be programmed to clear emergencies. 
9.24  STEALTH MODE 
Press the button programmed for Stealth Mode operation to toggle Stealth Mode on or off. During Stealth 
Mode, all buttons are disabled except PTT, the button programmed for Stealth operation, Emergency, and 
Nuisance delete. The radio will receive and transmit when Stealth Mode is enabled. 
The radio can be configured to disable any or all of the following during Stealth Mode: 
 LCD display 
 LED 
 Backlight 
 Side/alert tones 
Stealth Mode can be configured to persist through a power cycle. 
9.25  INDIVIDUAL CALLS 
9.25.1 Receiving and Responding to an Individual Call 
When the radio receives an individual call (a call directed only to the user's radio), it un-mutes on the 
assigned working channel and displays  . The first line on the display shows the logical ID number of 
the unit sending the message, or the associated name if the ID number is found in the individual call list. 
The radio can be programmed to ring when an individual call is received. If enabled, the ring begins five 
seconds after the caller un-keys and will continue until the PTT button, the   button, or the individual 
call mode is entered. 
The volume of the ring is adjustable through the volume control levels. 
If a response is made by pressing the PTT to the call prior to the programmed call-back time-out, the call 
will automatically be directed to the originating unit. If a response is not made before the call-back time-
out, the radio will return to normal receive display, and *WHC* will appear on the first line of the LCD.  
To respond after the call-back time-out, press the   key. The radio's display will show the callers ID on 
the  first  line  and  WHCI=1  on  the  second  line.  Pressing  the  PTT  button  at  this  point  will  initiate  an 
individual call back to the original caller.  
The radio stores the IDs of the last 10 callers in the Calls Received List as shown. Individual calls are 
stored in the top half of the list (1-10) and Group calls are stored in the bottom half of the list (1-10). The 
most recent call is stored in position 1, the second most recent call is stored in position 2, etc.

system is selected. 
3. To terminate the call, momentarily press the   button. 
9.26.3 Dual-Tone Multi-Frequency: Overdial 
Once the radio has established a connection to the public telephone system, it may be necessary to “over-
dial”  more  digits  to  access  banking  services,  answering  machines,  credit  card  calls,  or  other  types  of 
systems that require Dual-Tone Multi-Frequency (DTMF) access digits. 
Overdial operation can also be used to initiate a telephone interconnect call via DTMF signaling if a dial 
tone has already been accessed on the system. This method makes a telephone interconnect call while 
operating  in  the  conventional  mode  but  will  also  function  in  trunked  mode  if  a  dial  tone  is  directly 
accessible. 
Telephone numbers  and  other number sequences for overdialing can be stored in the phone list when 
programming  the  radio.  These  numbers  are  accessed  by  pressing  the    key,  then  following  the

9.27  PRE-STORING INDIVIDUAL AND TELEPHONE INTERCONNECT 
CALLS FROM THE KEYPAD 
Individual Call ID numbers, telephone numbers, and other number sequences for overdialing are stored in 
the  special  calls  lists  when  programming  the  radio. The  first  ten  entry  locations of  these  lists  can  be 
changed by the radio operator. The keypad is used when adding, changing, and storing numbers in these 
entry locations.  
Use the following procedure to store a number in one of the first ten entries of a special call list:  
1. Press the   or   button to enter the individual call list or the phone call list.   is displayed. 
2. Scroll through the list  using the    or  keys until one of  the first ten entries is reached.  NO 
ENTRY is displayed if the location is empty.  
3. Enter the desired number. If necessary, a pause can be entered by pressing and holding 0-9,  , or 
 until an underscore appears in the display (telephone interconnect only). The individual call list 
entries will accept up to 5 digits. The phone call list entries accept a combination of up to 31 digits 
and pauses.  
4. Press and hold the   key until the display changes indicating that the number has been stored.  
Repeat steps 1-4 to store additional numbers, to change numbers already stored, or to change the storage 
location of a number. 
9.28  STATUS/MESSAGE OPERATION 
The Status and  Message operations allow for  the transmission of a  pre-programmed status or a pre-
programmed message to an EDACS or P25 site.  Each Status and Message is assigned an ID then cross-
referenced with the representative status condition (“Off Duty,” for example) or a message (“Call home”).  
In  addition,  Status  conditions  can  also  be  associated  with  a  programmable  Menu  entry  (required  for 
second method of transmitting a Status condition). 

14221-1100-2010, Rev. E

9.28.1 Status Operation 
System Model Radio 
One of two methods can be used to transmit a status condition. 
METHOD 1:  
1. Press the   key, then use the   or  buttons to scroll to the pre-programmed 
status  condition.  STATUS  and  0  through  9  pre-programmed  status  selections  are 
available from the menu.   
2. If STATUS  is  selected,  you  need to  enter the  number  of  the  status condition  you 
intend to transmit. If no status has been programmed for the selected number key, the 
radio  will  display  NO ENTRY.  A  valid  selection will  display the  status  for  a  pre-
programmed time. 
After the time-out expires or the   key has been pressed (the   key will override the 
time-out period), the status is selected and will be transmitted to the site or stored in the 
radio memory where it can be polled by the site at a future time.  
METHOD 2: 
1. Press the   key.  
2. Press  the  corresponding  pre-programmed  0  through  9  status  condition  key.    If  no 
status  has  been  programmed  for  the  selected  number  key,  the  radio  will  display 
NO ENTRY. A valid selection will permit the status condition to appear in the top 
line of the display and the status ID to appear in the second line of the display for a 
pre-programmed time.   
After the time-out expires or the   key has been pressed (the   key will override the 
time-out period), the status is selected and will be transmitted to the site or stored in the 
radio memory where it can be polled by the site at a future time. 
To view the currently selected status after it has been transmitted, press the   key and then the   key 
to ramp to STATUS, press the   key again and then the   button prior to the time-out period. If the 
status was not sent successfully to the site, the text associated with the status will flash in the display. 
The status selection can be changed by pressing a different status key 0 through 9, or the status operation 
can be cancelled by pressing  .  Both operations must be carried out prior to the time-out period.  
9.28.2 Message Operation 
The following method can be used to transmit a Message using the Message Operation. 
1. Press the   key. 
2. Press the corresponding pre-programmed 0 through 9 pre-programmed “message” key.  If no message 
has  been  programmed  for  the  selected  number  key,  the  radio  will  display  NO ENTRY.  A  valid 
selection will permit the message to appear in the top line of the display and the message ID to appear 
in the second line of the display for a pre-programmed time.   
The message selection can be changed by pressing a different message key 0 through 9, or the message 
operation  can  be  cancelled  by  pressing  .    Both  operations  must  be  carried  out prior  to  the  pre-
programmed time-out period.  
9.29  DYNAMIC REGROUP OPERATION (EDACS) 
Dynamic Regroup Operation permits multiple talk groups (up to eight) to be added to a radio via the 
system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will 

  14221-1100-2010, Rev. E 
93 
not be activated in a radio until the system manager sends an activation message. Each radio that receives 
and acknowledges the regrouping instructions is successfully regrouped.  
Pressing and holding the   button for 2.5 seconds toggles the user into and out of the dynamic regroup 
groupset. A double beep will sound for entry or exit. The display will indicate REGRP_0x where "x" is a 
digit of 1 to 8 indicating the group (when dynamic regroup has been enabled by the user). If the radio is in 
dynamic regroup and  the user selects a  group  that has not  been  regrouped, the display will  show  NO 
ENTRY. The radio will be prevented from transmitting  and receiving calls in this condition except for 
scanned groups.  
After the time-out expires or the   key has been pressed, the status is selected and is transmitted to the 
site or stored in radio memory where it can be polled by the site at a future time. 
If the pre-programmed groupset on the currently selected system contains an EMER/HOME group and 
the radio is in dynamic regroup, the radio will declare the emergency on the currently selected dynamic 
group. 
9.30  MACRO KEY OPERATION 
Macro  key  operation  permits  the  user  to  accomplish  a  series  of  keystrokes  with  a  single  "macro" 
keystroke. Each macro key is capable of executing up to twenty (20) keystrokes, to any push button input 
(i.e., keypad keys, option buttons, etc.). Each macro key can be pre-programmed to activate when pressed 
or when released. A macro key can also be pre-programmed to change the key stroke sequence the next 
time the macro key is activated.  
For  detailed  operation  and  assignment  of  macro  keys,  contact  your  communications  supervisor  or 
administrator. 
9.31  DATA COMMUNICATIONS 
The XG-75P series portable radios permit both voice and data calls to be transmitted and received. The 
radio can handle only one type of call at a time; however, either data or voice is selected transparently by 
the operator through normal usage of the radio.  
The  radios  can  be  connected  to  a  Mobile  Data  Terminal  (MDT)  or  to  a  host  computer.  Any  RS-232 
compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) may be 
connected  to  the  radio.  Support  for  MDTs  or  host  computers  is  a  programmable  option  per  radio. 
Additionally,  radios  may  also  be  programmed  for  data  only  operation  (no  voice  calls  transmitted  or 
received). 
9.31.1 Displays 
The following will be displayed during data operation: 
DATA T/R 
Appears on top line of display when the radio is transmitting/receiving a data call.  
DATA OFF 
Appears on top line of display when the radio is in the data disabled state.  
DATA ON 
Appears  for  two  seconds  on  top  line  of  display  when  the  radio  is  toggled  to  the  data 
enabled state.  
9.31.2 Data Off Operation 
The radio can be placed in the data disabled state by any of the following methods. When the data state is 
disabled, DATA OFF appears on the top line of the display.  

14221-1100-2010, Rev. E

appear on the top line in the display for two seconds; then the display will return to normal.  
 Pressing the pre-programmed “no data” (ND) key toggles data state on or off.  
 Clearing an emergency. This is valid only if the emergency caused “DATA OFF” operation. 
9.31.4 Exiting Data Calls 
Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after 
completion of a data  call  (transmit  or  receive).  If, during  a  data  call,  one  of  the  following  operations 
occurs, the data call is immediately terminated and the radio performs the desired function:  
 If the PTT is activated. 
 If an Emergency is declared by pressing the pre-programmed emergency button. 
 If a group or system is changed. 
9.31.5 Scan Lockout Mode 
Following the transmission or reception of a data call, if scan is enabled, scanning will stop temporarily.  
There are two independent pre-programmed times associated with this mode; one after a received data 
call and one after a transmitted data call. During this time, the scan indicator will flash to indicate that 
scan  is  enabled  but  temporarily  suspended.  This  condition  typically  returns  to  normal  scan  operation 
when the pre-programmed time expires; however, the following operations and conditions will terminate 
the scan lockout mode before the timeout has expired. 
 Pressing the   button.  
 Pressing the PTT.  
 Changing a group or system.  
 Entering Telephone Interconnect mode.  
 Entering Individual call mode.

9.32  SELECTIVE SIGNALING (CONVENTIONAL) 
Selective  signaling  controls  the  muting  and  unmuting  of  the  receive  audio.    This  allows  a  user  or 
dispatcher to selectively call an individual radio or group of radios.  The XG-75P portable radios support 
selective signaling in Type 99 decode format.  
9.32.1  Type 99 Operation  
Type 99 is a conventional in-band, two-tone sequential signaling method.  This conventional signaling 
protocol  controls  the  muting  and  unmuting  of  a  radio.    Type  99  encoded  base  stations,  mobiles,  or 
portables can selectively call individual units or groups of units in a conventional system.  Type 99 is 
used in paging operations providing a dispatcher with the ability to selectively call a radio or a group of 
radios.    If  Type  99  is  enabled  in  the  radio  personality,  the  radio  can  decode  Individual,  Group,  and 
Supergroup Type 99 calls.  
In a selective signaling environment, the XG-75P portable radios operate in one of two states, Monitor 
mode or Selective Call mode.  
 In Monitor mode, Type 99 “OFF,” the decoder is disabled and all calls are heard by the user.  
 In Selective Call mode, Type 99 “ON,” the decoder is enabled and only calls intended for the user are 
heard.  
9.32.2 Type 99 with or without Channel Guard  
Selective signaling operates with or without Channel Guard.  If Channel Guard is enabled, the radio can 
be programmed with an "And" or an "Or" option, determined by programming with T99 Mute Control.  
 If  the  "And"  option  is  programmed,  T99  calls  require  the  correct  selective  signaling  (T99  tone 
sequence) AND the correct Channel Guard tones are heard by the user.  
 If the  "Or"  option  is  programmed,  calls  with  the  correct  Channel  Guard  tones  OR  calls  with  the 
correct T99 tone sequence and Channel Guard tones are heard by the user.  
A radio operating in Selective Call mode that receives a selective call switches to the Monitor mode (after 
decoding the T99 call) and the  TX/RX LED flashes green.    The  TX/RX LED indicates whether  the 
channel has a carrier signal.   
9.32.3 Resetting Type 99 after a Call  
After  decoding  a  Type  99  call,  the  radio  operates  in  Monitor  mode  and  all  traffic  on  the  channel  is 
audible.  If the channel has Channel Guard, only the traffic with the radio's Channel Guard tone will be 
heard.  
To reset Type 99 operation, use one of the following methods:  
 Press the   button.  
 Press the   button, if enabled through programming to toggle Type 99 on/off.  
 Allow the "Auto-Reset" timer, if enabled through programming, to reset the Type 99 decoder.  
9.32.4 Type 99 Disable after PTT  
The radio may be programmed with the Type 99 Disable after PTT feature, which automatically disables 
the Type 99 decoder after a transmission.  
Use one of the methods outlined in the Section 9.32.3 to reset Type 99 operation.  

14221-1100-2010, Rev. E   
96 
9.33  AUDIO PLAYBACK 
Every call received by the radio is recorded in internal memory, overwriting the last recorded call. When 
the PLAYBACK key is  pressed, the  last recording is  replayed and  any future recordings are  stopped. 
Pressing PLAYBACK again repeats the same recorded call. Pressing and holding the PLAYBACK key 
until the tone sounds erases the recording  and starts the recording of incoming calls again. If a call is 
received while the recorded call is playing, the recorded call continues to play, rather than the received 
audio. However, if a call is received and the recorded call is played back in close succession received 
audio could mute call playback.  This feature requires RPM R8A and later, and ECP R15A and later. 
The PLAYBACK function must be programmed to a button on the radio via RPM. 
9.34  RADIO TEXTLINK OPERATION 
Radio TextLink provides a simple means of exchanging pre-defined,  or  “canned,”  text  messages.  This 
section describes how to send messages if the Radio TextLink feature is enabled.

9.35  VIEW GPS INFORMATION 
If the GPS Speaker microphone is connected to the XG-75P, you can view your position and satellite 
information via the GPS Menu.  GPS requires an unobstructed view of the sky and the signal is greatly 
diminished inside buildings, tunnels, heavily forested areas, etc. GPS may not work at all under some 
conditions, especially in metal enclosures or buildings. 
1. Press   to access the menu. 
2. Press   or   to scroll through menu until GPS is displayed and press   to select. 
3. Press   or   to scroll through available information screens.  
9.36  CONTROL AND STATUS SERVICES 
The  XG-75P  supports  Control  and  Status  services.  These  services  allow  the  computer  application  to 
monitor  and  control  a  radio.  The  Control  and  Status  Services  can  be  used  from  a  locally-connected 
Mobile  Data  Terminal  (MDT)  or  a  network  MDT.  In  some  cases,  the  radio  can  support  both  MDTs 
simultaneously. However, priority is given to the local MDT. 
The Radio Status Service allows an MDT or Fixed End System (FES) to receive real-time status updates 
from a radio. An MDT sends Host Attach/Detach messages to the radio as UDP datagrams destined for 
the UDP Service Address and Service UDP Port of the radio. All responses and asynchronous reports are 
returned to the address and port of the requesting host. Refer to the ECP Control and Status Services 
Feature Manual, 14221-7200-6040, for more information on this feature.

The  Harris  Corporation  XG-75  portable  radio  generates 
RF  electromagnetic  energy  during  transmit  mode.    This 
radio  is  designed  for  and  classified  as  “Occupational  Use 
Only,”  meaning  it  must be  used only  during the course of 
employment  by  individuals aware of  the  hazards and the 
ways  to  minimize  such  hazards.    This  radio  is  NOT 
intended  for  use  by  the  “General  Population”  in  an 
uncontrolled environment. 
The XG-75P  portable radio has  been tested and  complies with the FCC RF 
exposure limits for “Occupational Use Only.”  In addition, this radio complies 
with  the  following Standards  and  Guidelines  with  regard  to  RF  energy  and 
electromagnetic  energy levels  and evaluation of  such levels for  exposure  to 
humans: 
 FCC  OET  Bulletin  65  Edition  97-01  Supplement  C,  Evaluating 
Compliance  with  FCC  Guidelines  for  Human  Exposure  to  Radio 
Frequency Electromagnetic Fields. 
 American National Standards Institute (C95.1 – 1992), IEEE Standard for 
Safety  Levels  with  Respect  to  Human  Exposure  to  Radio  Frequency 
Electromagnetic Fields, 3 kHz to 300 GHz. 
 American  National  Standards  Institute  (C95.3  –  1992),  IEEE 
Recommended  Practice  for  the  Measurement  of  Potentially  Hazardous 
Electromagnetic Fields – RF and Microwave. 
 DIRECTIVE  2004/40/EC  OF  THE  EUROPEAN  PARLIAMENT  AND 
OF THE COUNCIL of 29 April 2004 on the minimum health and safety 
requirements regarding the exposure of workers to the risks arising from 
physical agents (electromagnetic fields) and amended by: 
 Directive 2007/30/EC of the European Parliament and of the Council of 
20 June 2007 
 Directive 2008/46/EC of the European Parliament and of the Council of 
23 April 2008  
 Regulation  (EC)  No  1137/2008  of  the  European  Parliament  and  of  the 
Council of 22 October 2008  
 Directive 2012/11/EU of the European Parliament and of the Council of 
19 April 2012 

10  14221-1100-2020, Rev. B 
1.2.1  RF Exposure Guidelines 
CAUTION
To  ensure  that  exposure  to  RF  electromagnetic  energy  is 
within  the  FCC  allowable  limits  for  occupational  use 
and/or  the  exposure  limit  values  in  Annex  A  of  EU 
Directive  2004/40/EC,  always  adhere  to  the  following 
guidelines: 
 DO NOT operate the radio without a proper antenna attached, as this may 
damage the radio and may also cause the FCC RF exposure limits and/or 
the exposure limit values in Annex A of EU Directive 2004/40/EC to be 
exceeded.   A proper antenna is the antenna  supplied  with this radio  by 
Harris or an antenna specifically authorized by Harris Corporation for use 
with this radio. 
 DO NOT transmit for more than 50% of total radio use time (“50% duty 
cycle”).    Transmitting  more  than  50%  of  the  time  can  cause  FCC  RF 
exposure  compliance  requirements  and/or  the  exposure  limit  values  in 
Annex  A  of  EU  Directive  2004/40/EC  to  be  exceeded.    The  radio  is 
transmitting  when the  “TX”  indicator appears in the  display.   The  radio 
will transmit by pressing the “PTT” (Push-To-Talk) button. 
 ALWAYS  transmit  using  low  power  when  possible.    In  addition  to 
conserving battery charge, low power can reduce RF exposure. 
 ALWAYS  use  Harris  authorized  accessories  (antennas,  batteries,  belt 
clips, speaker/mics, etc).  Use of unauthorized accessories may cause the 
FCC  Occupational/Controlled  Exposure  RF  compliance  requirements 
and/or the exposure limit values in Annex A of EU Directive 2004/40/EC 
to be exceeded. 
 As noted in Table 1-1, ALWAYS keep the housing of the transmitter AT 
LEAST 1.6  cm  (0.63  inches)  from  the  body and  at  least  2.5  cm  (1.00 
inch)  from  the  face  when  transmitting  to  ensure  FCC  RF  exposure 
compliance requirements and/or the exposure limit values in Annex A of 
EU Directive 2004/40/EC are not exceeded.  However, to provide the best 
sound quality to the recipients of your transmission, Harris recommends 
you hold the microphone at least 5 cm (2 inches) from your mouth, and 
slightly off to one side.

1.2.3.1  Part 15 
This device complies with Part 15 of the FCC Rules. Operation is subject to 
the following two conditions:  
1. This device may not cause harmful interference, and  
2. This device must accept any interference received, including interference 
that may cause undesired operation. 
1.2.3.2  Industry Canada 
This device complies with Industry Canada license-exempt RSS standard(s). 
Operation is subject to the following two conditions: (1) this device may not 
cause interference, and (2) this device must accept any interference, including 
interference that may cause undesired operation of the device. 
1.3  OPERATING TIPS 
Antenna location and condition are important when operating a portable radio. 
Operating the radio in low lying areas or terrain, under power lines or bridges, 
inside of a vehicle or in a metal framed building can severely reduce the range 
of the unit. Mountains can also reduce the range of the unit.  

12  14221-1100-2020, Rev. B 
In areas where transmission or reception is poor, some improvement may be 
obtained by ensuring the antenna is vertical. Moving a few yards in another 
direction or moving to a higher elevation may also improve communications. 
Vehicular  operation  can  be  aided  with  the  use  of  an  externally  mounted 
antenna.  
Battery condition is another important factor in the trouble free operation of a 
portable radio. Always properly charge the batteries.  
1.3.1  Efficient Radio Operation 
Keep  the  antenna  in  a  vertical  position  when  receiving  or  transmitting  a 
message.  
WARNING
Do NOT hold onto the antenna when the radio is powered 
on. 
1.3.2  Antenna Care and Replacement 
WARNING
Always keep the antenna at least 1.6 cm (0.63 inches) from 
the body and at least 2.5 cm (1.00 inch) from the face when 
transmitting  to  ensure  FCC  RF  exposure  compliance 
requirements are not exceeded. 
WARNING
Do not use the portable radio with a damaged or missing 
antenna.  A  minor  burn  may  result  if  skin  comes  into 
contact  with  a  damaged  antenna.  Replace  a  damaged 
antenna immediately. Operating a portable radio with the 
antenna  missing  could cause personal injury,  damage the 
radio, and may violate FCC regulations. 
WARNING
Use  only  supplied  or  approved  antennas.  Use  of 
unauthorized  antennas,  modifications,  or  attachments 
could cause damage to the radio unit and may violate FCC 
regulations. 
1.3.3  Electronic Devices 
CAUTION
RF  energy  from  portable  radios  may  affect  some  electronic 
equipment.  Most  modern  electronic  equipment  in  cars, 
hospitals, homes, etc. are shielded from RF energy. However, 
in areas in which you are instructed to turn off two-way radio 
equipment, always observe the rules. If in doubt, turn it off! 

14221-1100-2020, Rev. B 13 
1.3.4  Aircraft 
WARNING
Always  turn  off  a  portable  radio  before  boarding  any 
aircraft! 
 Use it on the ground only with crew permission. 
 DO NOT use while in-flight!! 
1.3.5  Electric Blasting Caps  
WARNING
To prevent accidental detonation of electric blasting caps, 
DO NOT use two-way radios within 1000 feet of blasting 
operations. Always obey the "Turn Off Two-Way Radios" 
signs posted where  electric  blasting caps  are  being  used. 
(OSHA Standard: 1926.900) 
1.3.6  Potentially Explosive Atmospheres 
WARNING
Areas  with  potentially  explosive  atmospheres  are  often, 
but  not  always,  clearly  marked.  These  may  be  fuelling 
areas,  such  as  gas  stations,  fuel  or  chemical  transfer  or 
storage  facilities,  and  areas  where  the  air  contains 
chemicals  or  particles,  such  as  grain,  dust,  or  metal 
powders. 
Sparks  in  such  areas  could  cause  an  explosion  or  fire 
resulting in bodily injury or even death. 
Turn  OFF  two-way  radios  when  in  any  area  with  a 
potentially  explosive  atmosphere.  It  is  rare,  but  not 
impossible  that  a  radio  or  its  accessories  could  generate 
sparks.

2.2  RENSEIGNEMENTS SUR LA FORMATION SUR 
LA SÉCURITÉ 
MISE EN GARDE
La  radio  portative  Harris XG-75P  produit  de  l’énergie 
électromagnétique  des  RF  lorsqu’en  mode  de 
transmission.  Cette  radio  est  conçue  et  classée  pour  une 
« Utilisation  professionnelle  seulement »,  ce  qui  signifie 
qu’elle ne doit être utilisée que dans le cadre d’un emploi 
par des individus conscients des risques et des moyens de 
limiter ceux-ci. Cette radio N’EST PAS conçue pour une 
utilisation  par  la  « Population  générale »  dans  un 
environnement non contrôlé. 
La  radio  portative XG-75P  a  été  testée  et  est  conforme  aux  limites 
d’exposition  aux  RF  de  la  FCC  pour  une  « Utilisation  professionnelle 
seulement ». De plus, cette radio Harris est conforme aux normes et directives 
suivantes  quant  à  l’énergie  des  RF  et  aux  niveaux  d’énergie 
électromagnétique,  ainsi  qu’à  l’évaluation  de  ces  niveaux  pour  l’exposition 
aux humains : 
 Bulletin 65 du OET de la FCC, édition 97-01, supplément C, portant sur 
l’évaluation  de  la  conformité  aux  directives  de  la  FCC  quant  à 
l’exposition  humaine  aux  champs  électromagnétiques  des 
radiofréquences. 
 American National Standards Institute (C95.1 – 1992), norme de l’IEEE 
sur  les  niveaux  sécuritaires  d’exposition  humaine  aux  champs 
électromagnétiques des radiofréquences, 3 kHz à 300 GHz. 
 American  National  Standards  Institute  (C95.3  –  1992),  pratique 
recommandée par l’IEEE pour la mesure des champs électromagnétiques 
potentiellement dangereux – RF et micro-ondes. 
2.2.1  Directives sur l’exposition aux RF 
AVERTISSEMENT
Pour  s’assurer  que  l’exposition  à  l’énergie  électromagnétique 
des  RF  se  situe  dans  les  limites  acceptables  de  la  FCC  pour 
l’utilisation  professionnelle,  respectez  toujours  les  directives 
suivantes : 
 N’utilisez PAS la radio sans qu’une antenne appropriée y soit connectée, 
car ceci peut endommager la radio et également causer un dépassement 
des limites d’exposition aux RF de la FCC. Une antenne appropriée est 
celle fournie par Harris avec cette radio, ou une antenne spécifiquement 
autorisée par Harris pour être utilisée avec cette radio.  

16  14221-1100-2020, Rev. B 
 Ne transmettez PAS pendant plus de 50 % de la durée d’utilisation totale 
de la radio (« cycle de service de 50 % »). La transmission pendant plus 
de  50 %  du  temps  peut  causer  un  dépassement  des  exigences  de 
conformité de la FCC en matière d’exposition aux RF. La radio transmet 
lorsque  l’indicateur  « TX »  apparaît  sur  l’affichage.  La  radio  transmet 
lorsqu’on appuie sur le bouton « PTT » (bouton de microphone). 
 Transmettez TOUJOURS en basse puissance lorsque possible. En plus de 
préserver la charge de la pile, une faible puissance réduit l’exposition aux 
RF. 
 Utilisez  TOUJOURS  des  accessoires  autorisés  Harris  (antennes,  piles, 
pinces de ceinture, haut-parleurs/micros, etc.). L’utilisation d’accessoires 
non autorisés peut entraîner un dépassement des exigences de conformité 
pour  une  exposition  aux  RF  professionnelle  ou  contrôlée  de  la  FCC. 
(Reportez-vous à Tableau 2-1.) 
 Tel qu’indiqué dans Tableau 2-1, conservez TOUJOURS l’appareil et son 
antenne à  AU MOINS 1,6 cm (0,63 po) du corps, et à au moins 2,5 cm 
(1,0 po) du visage pendant la transmission, pour vous assurer de ne pas 
dépasser les exigences de conformité de la FCC en matière d’exposition 
aux RF. Cependant, pour offrir la meilleure qualité sonore aux auditeurs 
de  votre  transmission,  Harris  recommande  de  tenir  le  microphone  à  au 
moins 5 cm (2 po) de votre bouche et légèrement déplacé sur un côté.

2.4  CONSEILS D’UTILISATION 
L’emplacement et l’état de l’antenne sont importants pour l’utilisation d’une 
radio  portative.  L’utilisation  de  la  radio  dans  des  zones  de  faible  élévation, 
sous des lignes électriques ou des ponts, à l’intérieur d’un véhicule ou dans un 
immeuble  à  ossature  métallique,  peut  réduire  la  portée  de  l’appareil  de 
manière considérable. Les montagnes peuvent également réduire la portée de 
l’unité.  
Dans les zones où la transmission ou la réception est insatisfaisante, certaines 
améliorations peuvent être obtenues en s’assurant que l’antenne est verticale. 
Se déplacer de quelques mètres dans une autre direction ou à un emplacement 
plus élevé peut également améliorer les communications. L’utilisation d’une 
antenne fixée à l’extérieur peut faciliter le fonctionnement dans un véhicule.  
L’état  de  la  pile  est  un  autre  facteur  important  d’une  utilisation sans  tracas 
d’une radio portative. Chargez toujours correctement la pile.  

18  14221-1100-2020, Rev. B 
2.4.1  Utilisation Efficace de la Radio 
Gardez  l’antenne  dans  une  position  verticale  pendant  la  réception  ou  la 
transmission d’un message.  
MISE EN GARDE
Ne tenez PAS l’antenne lorsque la radio est allumée! 
2.4.1.1  Entretien Et Remplacement De L’antenne 
MISE EN GARDE
N’utilisez  pas  la  radio  portative  si  son  antenne  est 
endommagée  ou  absente.  Une  brûlure  légère  peut  se 
produire  au  contact  d’une  antenne  endommagée  avec  la 
peau.  Remplacez  immédiatement  une  antenne 
endommagée. L’utilisation d’une radio portative alors que 
l’antenne  est  absente  peut  causer  des  blessures, 
endommager  la  radio  et  pourrait  enfreindre  la 
réglementation de la FCC. 
AVERTISSEMENT
Utilisez seulement l’antenne fournie ou une antenne approuvée. 
Des antennes non autorisées, des modifications ou des ajouts à 
une  antenne  peuvent  endommager  la  radio  et  enfreindre  la 
réglementation de la FCC.  
2.4.1.2  Appareils Électroniques 
AVERTISSEMENT
L’énergie des RF provenant  de radios portatives peut affecter 
certains  appareils  électroniques.  La  majorité  de  l’équipement 
électronique  moderne  dans  les  voitures,  les  hôpitaux,  les 
maisons,  etc.  est  blindé  contre  l’énergie  des  RF.  Cependant, 
dans les zones où  l’on vous demande de fermer l’équipement 
de radio bidirectionnelle, respectez toujours les règles. En cas 
de doute, éteignez-le! 

14221-1100-2020, Rev. B 19 
2.4.1.3  Avion 
MISE EN GARDE
 Éteignez  toujours  une  radio  portative  avant 
d’embarquer à bord d’un avion! 
 Ne l’utilisez au sol qu’avec la permission de l’équipage. 
 NE l’utilisez PAS durant le vol! 
2.4.1.4  Détonateurs Électriques  
MISE EN GARDE
Pour  prévenir  la  détonation  accidentelle  des  détonateurs 
électriques,  n’utilisez  PAS  de  radios  bidirectionnelles  à 
moins  de  305 m  (1 000 pi)  des  opérations  de  détonation. 
Respectez  toujours  les  indications  « Éteindre  les  radios 
bidirectionnelles » situées là où des détonateurs électriques 
sont utilisés. (Norme OSHA : 1926.900) 
2.4.1.5  Atmosphère Potentiellement Explosive 
MISE EN GARDE
Les zones ayant une atmosphère potentiellement explosive 
sont  souvent,  mais  pas  toujours,  identifiées  clairement 
comme  telles.  Il  peut  s’agir  de  zones  d’alimentation  en 
carburant, comme les postes d’essence, les installations de 
stockage  ou  de  transfert  de  carburant  ou  de  produits 
chimiques,  ainsi  que  les  zones  dont  l’air  contient  des 
produits chimiques  ou  des particules,  comme des  grains, 
de la poussière ou des poudres métalliques. 
Des étincelles dans de telles zones peuvent provoquer une 
explosion  ou  un  incendie,  causant  ainsi  des  blessures  ou 
même la mort. 
Éteignez les radios bidirectionnelles dans toute zone ayant 
une atmosphère potentiellement explosive. Il est rare, mais 
pas impossible qu’une radio ou ses accessoires produisent 
des étincelles.

4.  BATTERY PACKS 
The XG-75  series portable  radios use rechargeable, recyclable  Nickel Metal 
Hydride (NiMH), Lithium-Ion (Li-Ion), or Lithium Polymer (Li-Poly) battery 
packs. Please follow the directions below to maximize the useful life of each 
type of battery pack. 
WARNING
Do  not  disassemble  or  modify  Lithium  battery  packs.  
Lithium  battery  packs  are  equipped  with  built-in  safety 
and protection features.  Should these features be disabled 
or  tampered  with  in  any  way,  the  battery  pack  can  leak 
electrolyte, overheat, emit smoke, burst, and/or ignite. 
WARNING
If  the  battery  pack  is  ruptured  or  is  leaking  electrolyte 
that  results  in  skin  or  eye  contact  with  the  electrolyte, 
immediately  flush  the  affected  area  with  water.  If  the 
battery electrolyte gets in the eyes, flush with water for 15 
minutes and consult a physician immediately. 
CAUTION
Always  use Harris  authorized chargers  and  conditioners.  Use 
of  unauthorized  chargers  and  conditioners  may  void  the 
warranty. 
4.1  CONDITIONING NIMH BATTERY PACKS 
Condition a new NiMH battery pack before putting into use. This also applies 
to  rechargeable NiMH battery  packs  that  have  been  stored for  long  periods 
(weeks,  months,  or  longer).  Conditioning  requires  fully  charging  and  fully 
discharging the  battery pack  three (3)  times using the  tri-chemistry charger.  
The first time the battery pack is put into the charger, this unit will condition 
Nickel-based  battery  packs  by  automatically  charging  and  discharging 
(cycling) the battery.  Refer to the appropriate charger manual for details. 

14221-1100-2020, Rev. B 21 
CAUTION
Failure to properly condition NiMH battery packs before initial 
use will result in shortened performance by the battery. 
4.2  CONDITIONING LI-ION OR LI-POLY PACKS 
Lithium battery packs  do not suffer from memory effect and do  not require 
conditioning.   
4.3  STORING LI-ION BATTERY PACKS 
If  a  battery  pack  is  expected  to  be  idle  for  a  month  or  more,  it  should  be 
properly prepared.  Li-Ion battery packs should  not be  stored fully charged.  
Before storing the battery pack, discharge it to 40% capacity.  If the battery is 
not discharged prior to storage, its overall capacity may be reduced.  Although 
all battery packs experience some capacity loss during storage, the shelf life 
for Li-Ion battery packs is about 3 months.  However, note that any capacity 
drop which occurs during storage is permanent and cannot be reversed. Li-Ion 
battery packs should be purchased and used immediately.  They should not be 
stock-piled without a rotating stock plan.
