2008  
 Directive 2012/11/EU of the European Parliament and of the Council of 19 April 2012 
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. 
• 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 1.5  cm (0.59 
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.

1.4 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 battery.

Do NOT hold onto the antenna when the radio is powered on! 
1.4.1.1 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.) 
1.4.1.2 Electronic Devices 
RF energy from portable radios may affect some electronic equipment.  Most modern 
electronic equipment in cars, hospitals, homes, etc. is 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! 
1.4.1.3 Aircraft 
• 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!! 
1.4.1.4 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:

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 1,5 cm 
(0,59 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.

non souhaité de l’appareil. 
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.  
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. 

 14221-1500-2000, Rev. K 
21 
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 bidire
ctionnelles dans toute zone ayant une atmosphère 
potentiellement explosive. Il est rare, mais pas impossible qu’
une radio ou ses 
accessoires produisent des étincelles. 

14221-1500-2000, Rev. K

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. Wipe dry with clean cloth.

4. BATTERIES 
The XG-25P series portable radios use rechargeable, recyclable Nickel Metal Hydride (NiMH), Lithium 
Polymer (Li-Poly), or Lithium Ion (Li-Ion) 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 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. 
Always use Harris authorized chargers and conditioners. Use of unauthorized chargers 
and conditioners may void the warranty. 
4.1.2 Additional Information 
For more information regarding the proper care of portable radio battery packs or establishing a battery 
maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277 
(international - 1-434-455-6403) or via https://premier.pspc.harris.com/infocenter/. 
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 
WARNING
CAUTION
CAUTION

14221-1500-2000, Rev. K   
24 
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.  
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 type batteries require 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  NiMH battery packs are fully discharged (as indicated by the radio low battery warning) 
before re-charging.  Full discharge is not required for Lithium-Ion or Lithium Polymer battery packs. 
• Periodically condition NiMH  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 
5.1 GENERAL 
The XG-25P 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-25P portable radio 
delivers end-to-end digital voice and IP data communications.  It is designed to support multiple 
operating modes including: 
• P25 Trunked Mode 
• P25 Digital Conventional Mode 
• EDACS® (Enhanced Digital Access Communications System) or ProVoice™ Trunked Modes 
• Conventional Analog Mode 
• OpenSky® Trunked Protocol (OTP) 
The XG-25P portables can include all of these modes or just one. Additional modes of operation can be 
added with software updates. 
The  XG-25P 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 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 depends  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-25P.  Then refer 
to the corresponding section(s) within this manual for feature and operation information. 
The XG-25P series portable radios operate reliably even under adverse conditions. These radios meet 
MIL-STD-810G specifications for wind driven rain, humidity, and salt fog.

7. EDACS, CONVENTIONAL, AND P25 OPERATION 
7.1 TURNING ON THE RADIO 
1. Power on the radio by rotating the power on-off/volume knob clockwise. A short alert signal (if 
enabled through programming) indicates the radio is ready to use.  
2. The display shows the last selected system and group or a default system and group (depending on 
programming).  
3. Adjust the power on-off/volume knob to the desired volume level.  
4. Select the desired system and group. The display indicates the current system and group names.  
5. The radio is now ready to transmit and receive calls. 
In the trunked environment, CC SCAN is displayed if communication with the 
system's control channel cannot be established. This may occur if, for example, the 
radio is out of range of the trunking site. It may be necessary to move to another 
location or select another trunking system to re-
establish the control channel link for 
trunked mode operations. CC SCAN is displayed on the group line until a control 
channel is accessed.  The length of time before the radio enters CC Scan after losing 
communication with the Control Channel is configurable in RPM.   
7.2 CONTROLS 
The XG-25P portable radios feature two rotary control knobs and an emergency button located on the top 
of the radio (Figure 7-1).  The Push-To-Talk (PTT) button and two option buttons are located on the side 
(Figure 7-2) of the radio.  The front mounted keypad of the System model has 15 buttons and the Scan

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.  The amount of time before the 
radio enters Control Channel Scan after losing the control channel is configurable in RPM. 
7.21.2 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

49 
enabled, as explained in the following sections.  This priority scan timer is reset each time the PTT button 
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. 
7.21.2.1 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. 
7.22 EMERGENCY OPERATION 
The radio's emergency behaviour varies depending on radio programming.  When an emergency is 
declared, scanning stops and restarts only after the emergency has been cleared. 
7.22.1 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. 
7.22.2 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.  
2. When the working channel assignment is received, the radio sounds a single beep indicating the radio 
has auto keyed (see Table 7-4) 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.)

7.26 INDIVIDUAL CALLS 
7.26.1 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. 
7.27.3 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 
selection mode rules. Perform the following procedures to access and dial these stored numbers. 
Scan Model Radio 
1. Follow the procedure in Section 7.27.2 to establish a connection to the telephone system or consult 
the system administrator for the procedure to access a dial tone on the trunked or conventional 
system.  
2. Enter selection mode first to enable entry of overdial numbers by pressing the   button.  
3. Follow the selection mode rules to call up a stored number from the phone list: Use the   or  
buttons to scroll through the list of stored numbers.   is displayed. Press the PTT to send the overdial 
sequence once. If the number needs to be transmitted again it must be selected or entered again (this 
prevents unwanted numbers from being sent the next time the PTT button is pressed during the call).  
Overdial select/entry mode remains active until the call is dropped, cleared, or   is pressed. The 
overdial select/entry mode can be re-entered if the call is still active by pressing  .

7.29 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). 
7.29.1 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 statu
s 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. 
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. 
View the currently selected status after it has been transmitted by pressing the   key and then the   
key 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 condition 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.  
7.29.2 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.  

 14221-1500-2000, Rev. K 
57 
7.30 DYNAMIC REGROUP OPERATION (EDACS) 
The 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 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. 
7.31 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 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. 
7.32 DATA COMMUNICATIONS 
The XG-25P series portable radios, when operating in trunked configuration, 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. Data 
communications is not supported in conventional mode.  
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). 
7.32.1 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. 

14221-1500-2000, Rev. K   
58 
7.32.2 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.  
• Declaring an emergency (not to be used unless an actual emergency condition exists). Alert tone will 
sound.  
• Pressing button   (if pre-programmed as “no data” key). Alert tone will sound.  
• Pressing the pre-programmed “no data” (ND) key.  Refer to previous bullet. 
7.32.3 Data On Operation 
The data state is enabled by one of the following (depending on how it was disabled). DATA ON will 
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. 
7.32.4 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. 
7.32.5 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. 
• Press the   button.  
• Press the PTT.  
• Change a group or system.  
• Enter Telephone Interconnect mode.  
• Enter Individual call mode.  
• Receive a new emergency assignment.  
• Declare or clear an emergency.  
• Receive an individual or phone call.  
• Receive an Agency, Fleet, or System All Call. 
• Press   (Scan model) or   (System model) to toggle Scan on or off.

59 
7.32.6 Data Lockout Mode 
During the voice call scan hang time (pre-programmed), the radio does not receive data calls. 
7.33 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-25P portable radios support 
selective signaling in Type 99 decode format.  
7.33.1 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-25P 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 
will be heard.  
7.33.2 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.   
7.33.3 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.  

14221-1500-2000, Rev. K   
60 
7.33.4 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 7.33.3 to reset Type 99 operation.  
7.34 RADIO TEXTLINK OPERATION 
Radio TextLink provides a simple means of exchanging pre-defined, or “canned,” text messages. This

8. OPENSKY OPERATION 
OpenSky is only available in 700/800 MHz models of the XG-25P series portable radios. 
Once an OpenSky system has been selected from the available systems on your XG-25P series portable 
radio, the characteristics described in the following sections govern operation. 
8.1 CONTROLS 
The XG-25P portable radio features two rotary control knobs and an emergency button on the top of the 
radio.  Refer to Figure 8-1.  The Push-To-Talk (PTT) button and two option buttons are located to the left 
side of the radio keypad, see Figure 8-2.  The front mounted keypad of the System model radio has 15 
buttons and the Scan model radio has six buttons.  Refer to Figure 8-3 and Figure 8-4.  
Figure 8-1: Top View Figure 8-2: Side View 
8.1.1 Buttons, Knobs, and Switch 
The functions of the buttons and knob controls vary depending on the mode of operation.  Their functions 
while in the OpenSky mode of operation are discussed in the following paragraphs.  
Table 8-1: Buttons, Knobs, and Switch Functions 
POWER 
ON-OFF 
VOLUME KNOB 
The Power On-Off/Volume Knob is rotated to apply power to the radio, 
and adjust audio volume up and 
down.   
Rotating the control clockwise applies power to the radio. Rotating the control clockwise 
increases the 
volume level.  Minimum volume levels may be programmed into the radio to prevent missed calls due to 
a low volume setting. While adjusting the volume, the display will momentarily indicate the volume level 
(e.g., VOL=39).  The volume range is from a minimum programmed level of 1 (displayed as OFF 
in the 
display) up to 39, which is the maximum level.

8.1.4 Radio Status Icons 
Status Icons indicate the various operating characteristics of the radio. The icons show operating modes 
and conditions and appear on the third line of the display (see Table 8-3). 
Table 8-3: OpenSky Icons Descriptions 
STATUS ICON DESCRIPTIONS 
Steady – Received Signal Strength Indicator (RSSI).   
Steady – Radio is data registered.

8.2 TRI-COLOR LED 
Figure 8-7: 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 8-7).   
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 LOGIN 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. 
If encryption is enabled and authorized on the radio, the user will be prompted to “Pls Login” with the *1 
login command, a User ID, and password. 
1. Press *1 keys (Login command). 
2. Enter the full 10-digit User ID. 
3. Press the   key. 
4. Enter the password.  
• If the radio is configured for alpha-numeric passwords and the password has consecutive 
duplicate numbers (“MES33” for example), enter #, the   key, between the consecutive 
duplicate numbers so the radio will not interpret the entry as a letter (“D” in this example). 
• If the radio is configured for numeric-only passwords, do not press the   key  between 
duplicated numbers. 
5. Press the   key twice for alpha-numeric passwords or once for numeric-only passwords. 
The User ID may be remembered from the previous login. (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. 

14221-1500-2000, Rev. K   
66 
If necessary, contact radio system administration personnel for login assistance and/or 
radio-specific login 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 login. If a user is logged in, it is necessary to log-off. 
8.5 PERSONALITY 
As illustrated in Figure 8-8, a personality defines the profiles and talk groups available to the user.  It is 
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 login (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 8-8: 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

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/alias1, 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-25P radio also provides audible Alert Tones or “beeps” to indicate the various operating 
conditions (see Table 8-4).

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.

2. While holding the   button, press the   button on the side of the radio. 
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. 

14221-1500-2000, Rev. K   
76 
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. 
System and Scan 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. 
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.

8.20.1 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. 
8.20.2 From ECP to OTP Mode 
Press the   or  buttons  to cycle through available systems until “OPEN SKY” appears in the 
display.  After a brief pause, 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.  
NOTE

14221-1500-2000, Rev. K   
78 
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.  
NOTE

 14221-1500-2000, Rev. K 
79 
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. 
NOTE
NOTE

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. 
• Default emergency group in emergency state. 
• Selected talk group. 
• Emergency capable group in emergency state. 
• Priority 1 talk group. 

 14221-1500-2000, Rev. K

• Priority 3 talk group. 
• Other (non-priority). 
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. 
NOTE

14221-1500-2000, Rev. K   
82 
Selective calls are terminated if an emergency is declared.  The network limits selective 
calls to 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).  Note that 
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 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 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. 
NOTE

8.28 EMERGENCY COMMUNICATIONS 
The XG-25P 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 t
here 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.  Note that 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. 
8.28.1 Declaring an Emergency Call or Alert 
1. Press the red emergency button on the radio to enter emergency mode. 
The emergency behavior for the selected profile is configured by the network 
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-25P 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. 
8.29.1.1 Using Automatic Encryption 
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 login). 
3. Login 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 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.   
NOTE
NOTE

 14221-1500-2000, Rev. K 
89 
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. 
8.29.2.1 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 
describes how to send a status message via the keypad and Section 8.30.2 describes how to send a status 
message via the menu. 
8.30.1 Send Status Message via the Keypad (System Model Radios Only) 
1. Press *2 <0…9> # on the keypad.  
2. A Status message can be associated with each key (0 – 9). This text is displayed on the first line of the 
display when the key is pressed until another key is pressed. 
• If no messages have been configured, “No Messages” is displayed. 
• If a message is not assigned to a key, “No Entry” is displayed for the keypad sequence. 
• You can press multiple keys to select the desired Status message. 
3. The # key terminates the keypad sequence and sends the currently selected status message. If no 
messages have been configured or no message is associated with the key, no message is sent and an 
error tone is played. 
Press the * key to cancel the keypad sequence. 
8.30.2 Send Status Message via the Menu 
1. Press   or  until “Status Msg” appears and press  . If no messages have been configured,

3. Press the   button to send the currently selected message. If no messages have been configured, no 
message is sent and an error tone sounds.  
Press   or  to cancel status message selection. 
8.31 REQUEST TO TALK (RTT) MESSAGES 
If enabled via programming, the RTT message feature allows you to send a short service message to the 
VNIC. Section 8.31.1 describes how to send an RTT message via the keypad and Section 8.31.2 describes 
how to send an RTT message via the menu. Note that only one RTT message can be programmed into the 
radio. 
8.31.1 Send RTT Message via the Keypad (System Model Radios Only) 
1. Press *5 <0…9> # on the keypad. The key associated with the RTT message (0-9) is configured via 
programming. 
2. This message is displayed on the first line of the display when the key is pressed until another key is 
pressed.  
• If no message has been configured, “No Message” is displayed. 
• If a message is not assigned to the key, “No Entry” is displayed for the keypad sequence. 
3. The # key terminates the keypad sequence and sends the currently selected RTT message. If no 
message has been configured or no message is associated with the key, no message is sent and an 
error tone is played. 
Press the * key to cancel the keypad sequence.

Press   or   to cancel RTT message selection. 
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.

91 
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 
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. Note that the override 
is only successful if the V-TAC operating mode matches the manually selected portable V-TAC mode. 
NOTE

92 
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 login, 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 login, 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 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. 

 14221-1500-2000, Rev. K 
93 
8.34.5 Use XCOV-TG Mode  
When using the XCOV-TG mode, up to 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 P5300.  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.  

14221-1500-2000, Rev. K   
94 
• 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.  
Press *40# or use the Client Mode menu to return to normal operation (Network Mode).  The personality 
and profile in use at the time the radio entered SOI mode is restored. 
SOI Mode, Manual Channel Entry (All XG-25P Models) 
1. Press   or   until the Client Mode menu appears.

2. Select New Master Set, Open, or Import from Security Device. Refer to the Key Admin online 
help for more information on creating keys. 
3. When finished, create a Distribution Key File. A Distribution Key File is used with the Key Loader to 
load key sets into the radio and cannot be edited. Refer to the Key Admin online help for more 
information on creating the Distribution Key File. 
A.2 LOAD ENCRYPTION KEYS  
A.2.1 Load UKEKS with Key Loader and RPM (for OTAR-Enabled Systems) 
UKEKs are loaded into Harris OTAR radios using the Key Loader application.  Key Loader is a part of 
Key Manager.  
To load encryption keys: 
1. Obtain the UKEK file and Storage Location Number (SLN) Binding Report information from the 
Crypto Officer (CO). 
Both AES and DES UKEKs can be contained within the same UKEK file. 
2. If not already on, power-up the PC that has RPM and the Key Loader applications installed on it, and 
start Windows®.

A.2.4 Load Keys Using Motorola KVL Device 
Type 3 Digital Encryption Standard Output Feedback (DES-OFB) and Advanced Encryption Standard, 
256-bit  (AES-256), encryption methods are supported. The Type 3 Encryption keys are loaded via a 
Motorola Device using Telecommunications Industry Association (TIA)/Project 25 (P25) key fill device 
protocol. Make sure that valid keys have been created and stored in the KVL Device before proceeding. 
A.3 PROTECTED KEYS 
The Protected Keys feature transfers P25 Voice Keys, from Harris Key Loader to the radio, that have 
been wrapped (AES) or encrypted (DES) with Key Protection Keys (KPKs). KPKs are nothing more than 
unprotected Key Encryption Keys (KEKs). The KPKs need to be loaded into the radio before the 
Protected Keys are loaded. Once loaded into the radio, the KPKs will be used to unwrap (AES) or decrypt 
(DES) the Protected Keys. 
The radio must be placed into the key loading mode (see Section A.2.2) in order to accept the KPKs and 
P25 Voice Keys.
