1 SAFETY CONVENTIONS 
The following conventions are used throughout this manual to alert the user to general safety precautions 
that must be observed during all phases of operation, service, and repair of this product. Failure to comply 
with these precautions or with specific warning elsewhere in this manual violates safety standards of 
design, manufacture, and intended use of the product. M/A-COM, Inc. assumes no liability for the 
customer’s failure to comply with these standards. 
The WARNING symbol calls attention to a procedure, practice, or the like, which, if 
not correctly performed or adhered to, could result in personal injury. Do not 
proceed beyond a WARNING symbol until the conditions identified are fully 
understood or met. 
CAUTION
The CAUTION symbol calls attention to an operating procedure, practice, or the like, 
which, if not performed correctly or adhered to, could result in damage to the equipment 
or severely degrade the equipment performance. 
The NOTE symbol calls attention to supplemental information, which may improve 
system performance or clarify a process or procedure. 
The ESD symbol calls attention to procedures, practices, or the like, which could expose

2  SAFETY TRAINING INFORMATION 
The M/A-COM P5300 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 P5300 portable radio has been tested and complies with the FCC RF exposure limits for 
“Occupational Use Only.”  In addition, this M/A-COM 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. 
2.1 RF EXPOSURE GUIDELINES 
CAUTION  
To ensure that exposure to RF electromagnetic energy is within the FCC allowable 
limits for occupational use, 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 to be exceeded. A proper antenna is the antenna supplied with 
this radio by M/A-COM or an antenna specifically authorized by M/A-COM 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 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 M/A-COM authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). 
Use of unauthorized accessories may cause the FCC Occupational/Controlled Exposure RF 
compliance requirements to be exceeded. (Refer to Table 2-1.) 
• As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 2.8 cm (1.1 inch) from 
the body and at least 2.5 cm (1.0 inch) from the face when transmitting to ensure FCC RF exposure 
compliance requirements are not exceeded. However, to provide the best sound quality to the 

MM-008212-001, Rev. p2 
12 
recipients of your transmission, M/A-COM recommends you hold the microphone at least 5 cm (2 
inches) from mouth, and slightly off to one side.

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.  
3.1  EFFICIENT RADIO OPERATION 
For optimum audio clarity at the receiving radio(s), hold the portable radio approximately two inches 
from your mouth and speak into the microphone at a normal voice level.  
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! 
3.1.1  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.) 
3.1.2 Electronic Devices 
CAUTION
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! 

MM-008212-001, Rev. p2 
14 
3.1.3 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!! 
3.1.4  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: 
1926.900) 
3.1.5  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. 

MM-008212-001, Rev. p2

4 BATTERIES 
The P5300 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd) or Nickel Metal 
Hydride (NiMH) batteries. Please follow the directions below to maximize the useful life of each type of 
battery. 
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.  This unit conditions a 
battery pack by automatically charging and discharging (cycling) the battery.   
CAUTION  
Failure to properly condition NiMH battery packs before initial use will result in 
shortened performance by the battery. 
4.1.2  Conditioning NiCD Battery Packs 
A new NiCD battery does not require conditioning before use.  However, M/A-COM recommends 
periodically conditioning NiCD batteries to avoid the memory effect which results in a NiCD battery 
when it is repeatedly charged and not fully discharged, resulting in a lower voltage and a lower capacity. 
Fortunately, both nominal voltage and capacity are restored through battery conditioning.    
CAUTION  
Always use M/A-COM authorized chargers and conditioners. Use of unauthorized 
chargers and conditioners may void the warranty. 
4.1.3 Additional Information 
For more information regarding the proper care of portable radio batteries or establishing a battery 
maintenance program, refer to ECR-7367 which may be ordered by calling toll free 1-800-368-3277, then 
select option 7. 

MM-008212-001, Rev. p2 
16 
4.2 CHARGING BATTERY PACKS 
Battery chargers are available from M/A-COM with nominal charge times of one hour. Combinations 
include single and multi-position, rapid charge units.  
M/A-COM chargers are rapid chargers specifically designed for charging nickel-based and lithium ion 
battery packs. The chargers are chemistry-specific for the battery packs and automatically adjust the 
charging rates accordingly.  Refer to the appropriate charger manual for specific operating instructions.  
4.2.1 Charging Guidelines 
Observe the following guidelines when charging a battery pack: 
• Avoid high temperature during charging.  
• Discontinue use if the charger is overheating. 
• Only charge M/A-COM battery packs using a charger approved for use by M/A-COM. 
• 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. 
4.3  BATTERY PACK USAGE 
Both nickel-based and lithium ion (Li Ion) batteries vary in capacity and life cycle. NiCd batteries have a 
longer life cycle than NiMH batteries whereas NiMH batteries have a larger capacity. Both types of 
batteries require basic usage guidelines be followed in order to increase the battery runtime or shift life. 
4.3.1 Usage Guidelines 
The following guidelines will help increase the battery runtime or shift life: 
• Ensure the battery pack is fully discharged (as indicated by the radio low battery warning) before re-
charging. 
• Periodically condition 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 extended. 
Do not leave batteries (NiCd, NiMH, or Li Ion) in a charger for more than a few days.

5 INTRODUCTION 
The P5300 series portable radio is available in two models: the P5350 Scan model with a limited 6-button 
front-mounted keypad and the P5370 System model with a 15-button DTMF front-mounted keypad. The 
900 MHz P5300 portable radio delivers end-to-end encrypted digital voice and IP data communications. 
It is designed to support multiple operating modes including: 
• OpenSky® Trunked mode (OTP) 
• EDACS® or ProVoice™ Trunked mode 
• Conventional Analog mode 
The P5300 portables can include all of these modes or just one. Additional modes of operation can be 
added with software updates. 
The P5300 supports a full range of advanced digital trunking features, including voice 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., OpenSky, EDACS, or 
ProVoice) 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. base station in an 
OpenSky system or 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 P5300. 
For further detail about features and operation refer to the appropriate maintenance manual or contact 
your System Administrator. 
5.1 WATER RESISTANCE 
The P5300 series portable radios operate reliably even under adverse conditions. These radios meet MIL-
STD-810F specifications for driven rain, humidity, and salt fog.

8.3 TRI-COLOR LED 
Figure 8-2: 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 8-2).  In OpenSky mode only two 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. 
8.4  LOG IN TO THE NETWORK 
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and 
authorized for encryption (Section 8.25), 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. 

MM-008212-001, Rev. p2 
37 
The User ID may be remembered from the previous log-in. (Refer to Section 8.5 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. 
8.5  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. Log-off manually by pressing     .   
If a user is logged in using encryption features, it is necessary to log-off when encryption is no longer 
required. 
8.6 PERSONALITY 
As illustrated in Figure 8-3, 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. When changes are made to the personality, the radio is automatically 
re-provisioned. Each personality can contain up to sixteen (16) profiles and each profile can contain up to 
sixteen talk groups. 
8.6.1 Profiles 
As stated above, each profile can contain up to sixteen (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.

8.6.2 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. 
8.7  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 8-2).  
8.7.1 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 8-4). 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. 
8.7.2 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.  
8.7.3 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. 
Press the   button repeatedly to scroll through and view one of these second line options.  
1 Alias is a logical ID name such as “J_Smith.”  The name corresponds to a user ID such as 003-542-0001.

8.11  CHANGING THE ACTIVE PROFILE 
The radio can store up to sixteen (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. 
8.12  CHANGING THE SELECTED TALK GROUP 
Each profile stored in the radio can have up to sixteen (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. 
8.13  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. 

MM-008212-001, Rev. p2 
43 
8.14 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 
light, indicator light and audible 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. 
8.14.1  Enabling Stealth Mode 
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. 
8.14.2  Disabling Stealth Mode 
To re-enable all lighting, side tones and exit Stealth Mode, press any key other than PTT or Emergency. 
This returns to the Dwell Display. 
The display lights, indicator lights, and side tones are re-enabled. The stealth mode icon disappears. 
With stealth mode on, pressing any radio button (other than the mic’s PTT button 
or the emergency button) on front panel will immediately turn stealth mode off. For 
example, pressing the   button on the front panel will turn stealth mode off. 
8.15  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.” 
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 
completely off, use the “Off” setting. 
8.16 CHANGE OPERATING MODE 
1. Press the   or  buttons to cycle through the menu until “Mode Menu” is displayed. 

MM-008212-001, Rev. p2 
44 
2. Press   or   to select the desired operating mode. 
3. Press   and use   or   to select Y or N. 
4. Press   again to make selection and return to the dwell display 
8.17 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.  
8.17.1  Receiving a Voice Call 
No action is required on the part of the user. 
The caller’s alias is only shown when the selected talk group matches the received talk group. Otherwise, 
the name of the received talk group is displayed. 
8.17.2  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. 
8.18  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. 
8.19  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 

MM-008212-001, Rev. p2 
45 
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 or when the radio is 
power cycled. 
If the Scan Mode is “Fixed,” P1 and P2 groups CANNOT be locked out. See Section 8.20 
for more information. 
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. 
8.19.1  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. 
8.19.2  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. 
8.20 SCANNING 
8.20.1  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. 

MM-008212-001, Rev. p2 
46 
Table 8-6: Scan Modes 
SCAN 
MODE  EXPLANATION 
No Scan 
Eliminates distractions.  
Full communications (listen and talk) with the active talk group. 
No calls received from other talk groups. 
Normal 
This is the default setting.  
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 and P2) 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, and default emergency talk groups 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  
The priority groups are fixed to the selected profile’s pre-defined P1 and P2 groups 
(configured via the UAS). In this mode, P1 and P2 groups CANNOT be locked out. 
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. 
Allows dragging of the P1, P2, and selected talk group to the site on which the radio is 
registered. If other calls are available at the site, they can also 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 in emergency mode. 
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. 
8.20.2 Checking or Changing Active Scan Mode 
8.20.2.1 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. 
8.20.2.2 Duration of Scanning Mode Selections 
Scanning Mode selections survive power down. At startup, the radio defaults to the scanning mode of set

• Priority 2 talk group. 
• Other (non-priority). 
8.20.3.1 Changing Scan Priority 
1. Press the   or  keys until “Priority1” or “Priority2” appears in the display (Priority1 group has 
higher priority than the Priorty2 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. 
• You set priority for two talk groups, but only in the selected profile. 
• The scanning priority settings are reset to the default values when the radio is turned 
off. 
8.21  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. 

MM-008212-001, Rev. p2

8.21.1  Manually Dialing a Selective Call (P5370 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># 
 <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 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 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. 
8.21.2  Selective Call Using Speed Dial 
Speed dial numbers are defined and provisioned by the OpenSky network administrator 
and cannot be manually entered into the radio by the user. Contact the administrator if 
changes to the speed dial list are required. 
1. Scroll through the Menu options using the   or  button until “Speed Dial” appears in the second 
line of the display. Using the   or   keys, scroll through the pre-programmed speed-dial numbers 
until the desired number appears in the display and press the PTT button.  
OR 
2. Press and hold a key associated with a given number for more than three seconds. For example, press 
and hold the   to open the Speed Dial Menu and display the number assigned to that key in the 
speed dial list. Press the PTT button. 
A 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, or the call is terminated due to an initiated 
emergency. 
If the called radio is involved in another selective call, “BUSY” will appear on the second line of the 
display. “Unavailable” is displayed when the call has not been answered after a 1 minute timeout or when 
the other party is not registered on the network.  
8.21.3  Accepting a Selective Call 
1. The radio will ring (like a telephone), indicating you are receiving a Selective Call.  
2. Press the   button to accept the incoming selective call.  

MM-008212-001, Rev. p2 
49 
3. “CONNECT” will appear in the display, followed by “Lim 10 Min.” “SEL CALL” and the alias of 
the caller appear in the display once the call is established. 
8.21.4  Rejecting a Selective Call 
When a Selective Call is being received (the radio is ringing), you can reject the call by pressing either of 
the   or  buttons, the   button, or by turning the Voice Group Selector Control knob. The call will 
be rejected and “Reject” appears on the callers display. 
8.21.5  Terminating a Selective Call 
Terminate a Selective Call (call must be active) by pressing the  , ,  ,  ,  , or   buttons, or 
by turning the Voice Group Selector Control knob. “HANGUP” will appear in the display followed by 
the active talk group. 
8.22 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. 
8.22.1 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 200 characters long. 
When sending a selective alert message, the radio may display one of the following status messages 
(Table 8-7). 
Table 8-7: Status of Selective Alert Messages 
STATUS MESSAGE  DEFINITION 
Delivering  Select Alert message transmit attempt 
Busy  Too busy – Try again 
Dest Down  Receiving radio not logged on – Not registered 
Not Reg  Transmitting radio not logged on – Not registered

2. To hang up the call, press  , ,  ,  , #, or  . 
8.24 EMERGENCY COMMUNICATIONS 
The P5300 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 3 distinct beeps that only goes 
to the dispatch console.  
Table 8-8: 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. 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. 

MM-008212-001, Rev. p2 
52 
8.24.1  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. 
All of the radios in the emergency talk group hear your call and see the emergency talk group displayed 
on their radio. 
8.24.2 Receiving an Emergency Call 
Initially, 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 8.24.3. 
8.24.3  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. 

MM-008212-001, Rev. p2 
53 
8.24.4  Clearing an Emergency Call or Alert 
1. When the emergency ends, press and hold the red emergency button for three to five seconds to clear 
the emergency alert and call while on the active emergency talk group. The remove tone sounds when 
the emergency is cancelled.  
2. The radio returns to your default selected talk group. The “EMERGENCY” display is removed from 
the main screen. 
An Emergency Alert can only be cleared by the dispatcher or the initiator. 
An Emergency Call can be cleared by the dispatcher, the initiator, or someone whose radio 
has supervisory privileges. 
8.25 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., P5300 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 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. 
8.25.1 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. 
8.25.1.1 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 log in). 
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 system administrator level, “SECURE” will 
appear in the 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 main display will alternate 
between no access “NO ACC” and the alias of the radio that is currently engaged in the secure call. The 
alias only shows if the active talk group matches the received talk group, otherwise only the talk group 
name is displayed. 

MM-008212-001, Rev. p2 
54 
8.25.2  Manual Encryption (P5370 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. Note that while a user is engaged in an 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. Encryption keys are lost if the profile is changed. 
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. 
8.25.2.1 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, “Secure” 
will appear in the display. 
If a secure (encrypted) call is in progress, and the user has not entered the key, the display will alternate 
between no access “No Access” and the alias of the radio that is currently engaged in the secure call. 
Once the user has terminated manual encryption “Unsecure” will appear in the display for a brief interval. 
8.26 DYNAMIC REGROUPING  
Dynamic regrouping requires that the network administrator determine which radio users should be 
formed into an impromptu talk group to respond to particular emergency conditions. 
The administrator will edit the personalities of the affected radios to include an emergency profile and 
then page the affected radios to re-register with the network to receive their edited personalities. 
In response, affected radios automatically re-register to receive their edited personalities. During re-
registration, subscriber equipment will default to the emergency profile selected by the administrator. 

MM-008212-001, Rev. p2

8.27 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]

9 EDACS OPERATION 
9.1  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. Refer to Figure 7-2 for 
location of the POWER ON-OFF/VOLUME KNOB. 
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 will be 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. 
9.2 CONTROLS 
The radio features two rotary control knobs and an emergency button mounted on the top of the radio. 
Push-To-Talk and option buttons are mounted on the side. The front mounted keypad has six buttons on 
the P5350 Scan model and 15 buttons on the P5370 System Radio. 
9.2.1  Buttons and Knobs 
This section describes the primary function of the button and knob controls. Other functions associated 
with these controls are detailed in later sections. 
POWER ON-OFF 
VOLUME KNOB  Applies power to and adjusts the receiver’s volume. Rotating the control clockwise 
applies power to the radio. A single alert tone (if enabled through programming) 
indicates the radio is operational. 
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 (i.e. VOL=31). The volume range is from a minimum programmed 
level of zero (displayed as OFF in the display) up to 31, which is the loudest level.
CONTROL KNOB  Selects systems or group/channels (depending on programming). This is a 16-
position rotary knob.  
Note: A mechanical stop, which can limit the positions accessed, is shipped with 
the radio but must be installed. To install the mechanical stop, remove the channel 
knob, loosen the set screw on the channel knob metal base (using a 1.27mm hex 
wrench), and remove the channel knob metal base. Replace the 16 channel ring 
with the channel stop ring located at the desired channel. Reinstall the channel 
knob metal base, tighten the set screw, and reinstall the channel knob.

9.19 DIGITAL VOICE OPERATION 
Digital voice programmed systems have two (2) different voice modes: clear (analog) and digital. The 
voice modes are programmed on a per-group basis within each trunked system. 
9.19.1 Clear Mode 
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice 
signals. These analog signals are non-digitized and non-encrypted. Clear mode transmissions can be 
monitored easily by unauthorized persons.  
Groups or channels programmed for clear operation cannot transmit or receive digital 
messages. 
9.19.2 Digital Mode 
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide 
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and 
channels programmed for digital operation transmit only digital signals. Message trunked group calls and 
individual phone calls (I-Calls) are answered back in the mode in which they were received assuming the 
call or hang time is still active. Individual phone, all call, and emergency calls are transmitted clear if the 
digital mode is disabled or inoperative. 
If receiving an analog message trunked call, the radio responds in the analog mode during the hang time 
on the working channel. 
If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 
When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is 
transmitted in the mode defined by the system mode as programmed for the current system if the ID being 
called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-
Call mode programmed in the list for that ID. 
The overdial DTMF tones are not available while in the Digital Mode. 

MM-008212-001, Rev. p2 
72 
9.19.2.1 Scanned Group Calls 
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang 
time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the 
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same 
group was available in digital and entered in the scan list, it can receive clear and digital calls, provided 
autoselect was programmed in the radio. The user can select transmitting on the scanned or selected 
group. If a group is entered in the scan list more than once and in different modes (clear or digital), only 
the first occurrence of the group will be used.

9.20  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.  
9.20.1  Turning Scan On and Off 
1. Toggle Scan operation ON by pressing  (P5350 model) or  (P5370 model).   icon rotates 
clockwise to indicate radio is scanning.  
2. Toggle Scan operation OFF by again pressing  (P5350 model) or  (P5370 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). 
9.20.2  Adding Groups to a Scan List 
P5350 Model Radio 
1. Scan must be OFF to add/delete groups to/from the scan list. If the Scan icon   is ON, press the

4. Press the  key a second time to set the group to Priority 2. A   is displayed on line three.  
5. Press  a third time to set the group to Priority 1. A   is displayed on line three. The priority level 
section sequence only advances the group to the next high priority level and stops at priority level 1. 
To select a lower priority level, the group must be deleted from the scan list and then added back to 
the scan list. Each new group added to the scan list starts at the lowest priority. If the Priority 1 and 
Priority 2 groups are already set and a new group is assigned as Priority 1 or Priority 2, the previously 
assigned group will change to non-priority scanning. One of the following messages may be 
momentarily displayed. 
SCAN DIS The radio is not programmed to scan.  
FIXED P1 A Priority 1 group has been pre-programmed into the radio. A new Priority 1 group 
cannot be selected.

9.21.1  Wide Area System Scanning 
The P5300 series radio can be programmed for Wide Area System Scan operation for roaming across 
mobile systems. 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. 
9.21.2  Priority System Scan 
The radio can also be 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 
programmable 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 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. 
9.21.2.1 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. 
9.21.2.2 When ProScan is Enabled 
The radio monitors the priority system and will switch to the priority system if the criteria defined by the 
controls in the ProScan Options dialog box 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, located in the ProScan 
Options dialog box. See Section 9.21.3 for more information on ProScan 
9.21.3 ProScan 
The radio may be programmed for ProScan system scan operation for multi-site applications depending 
on the version of radio flash code. ProScan is an improved multi-site system scanning algorithm designed 
to replace ProSound™ scanning. 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 is accomplished 
by enabling each radio to analyze the signal quality of its current control channel and compares 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. 
9.22 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. 

MM-008212-001, Rev. p2 
76 
9.22.1 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. 
9.22.2 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 9-3) 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. (This will work if the radio is programmed to clear emergencies.) 
9.23 INDIVIDUAL CALLS 
9.23.1  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.

9.24.3 Dual-Tone Multi-Frequency: Overdial/Conventional Mode 
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. 

MM-008212-001, Rev. p2 
80 
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. 
P5350 Model Radio

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. 
9.26 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 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 (see Section 9.26.1). 

MM-008212-001, Rev. p2 
82 
9.26.1 Status Operation 
P5370 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. 
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 Option Button 2  .  Both operations must be carried out prior to the time-
out period.  
9.26.2 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 Option Button 2  .  Both operations must be carried out prior to 
the pre-programmed time-out period.  
9.27  DYNAMIC REGROUP OPERATION 
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 

MM-008212-001, Rev. p2 
83 
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   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. 
9.27.1 Emergency Operation  
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. 
9.28 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 may 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. 
9.29 PORTABLE DATA 
The P5300 series portable radios, when operating in the EDACS 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). 
9.29.1 Displays 
The following will be displayed during the various states of data mode of operation: 
TX DATA Appears on top line of display when the radio is transmitting a data call.  
RX DATA Appears on top line of display when the radio is receiving a data call.  
DATA OFF Appears on top line of display when the radio is in the data disabled state.  

MM-008212-001, Rev. p2 
84 
DATA ON Appears for two seconds on top line of display when the radio is toggled to the data
enabled state.  
9.29.2  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 Option Button 1   (if pre-programmed as “no data” key). Alert tone will sound.  
• Pressing the pre-programmed “no data” (ND) key.  Refer to previous bullet. 
9.29.3 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. 
9.29.4  Exiting Data Cells 
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. 
9.29.5  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.

clockwise applies power to the radio. A single alert tone (if enabled through 
programming) indicates the radio is operational. 
Rotating the control clockwise increases the volume level. Minimum 
volume levels may 
b
e 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 (i.e. VOL=31). The volume range is 
from a minimum programmed level of zero (displayed as OFF in the 
display) up to 31, which is the loudest level. 
CONTROL KNOB  Selects systems or group/channels (depending on programming). This is a 
16-position rotary knob.  
Note: A mechanical stop, which can limit the positions accessed, is shipped 
with the radio but must be installed. To install the mechanical stop, remove 
the voice group selection knob, loosen the set screw on the voice group 
selection knob metal base (using a 1.27mm hex wrench), and remove the 
voice group selection knob metal base. Replace the 16 channel ring with the

10.17 DIGITAL VOICE OPERATION 
Digital voice programmed systems have two (2) different voice modes: clear (analog) and digital. The 
voice modes are programmed on a per-channel basis within each conventional system. 
10.17.1 Clear Mode 
The Clear Mode is a voice mode in which the radio transmits and receives only clear (analog) voice 
signals. These analog signals are non-digitized. Clear mode transmissions can be monitored easily by 
unauthorized persons.  
Channels programmed for clear operation cannot transmit or receive digital signals. 
10.17.2 Digital Mode 
The Digital Mode allows the radio to transmit and receive digitized voice signals. Digital signals provide 
improved weak signal performance and cannot be easily monitored with a standard receiver. Groups and 
channels programmed for digital operation transmit only digital signals. Individual phone calls (I-Calls) 
are answered back in the mode in which they were received assuming the call or hang time is still active. 
Individual phone, all call, and emergency calls are transmitted clear if the digital mode is disabled or 
inoperative. 
If receiving an analog I-Call, the radio responds in the analog mode during the hang time. 
When using the *WHC* feature to respond to an I-Call (after the hang time has expired), the call is 
transmitted in the mode defined by the system mode as programmed for the current system if the ID being 
called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined by the I-
Call mode programmed in the list for that ID. 
The overdial DTMF tones are not available while in the Digital Mode. 
10.17.2.1 Scanned Group Calls 
Receiving a Scanned Group Call is the same as receiving a selected group call. During the scan hang 
time, if the radio was programmed for autoselect, it will transmit back in the same mode it received the 

MM-008212-001, Rev. p2 
101 
call. For example, if a clear group is entered in the scan list, it will only receive clear calls. If the same 
group was available in digital and entered in the scan list, it can receive clear and digital calls, provided 
autoselect was programmed in the radio. The user can choose to transmit on the scanned or selected 
group. If a group is entered in the scan list more than once and in different modes (clear and digital), only 
the first occurrence of the group will be used.

10.18 RECEIVING A CALL 
1. Select the desired conventional system/channel or turn scan ON and make sure desired channel is in 
scan list. 
2. When the radio receives a call, the radio will unmute and the channel name will appear in the display. 
10.19  SENDING A CALL 
1. Select desired system/channel.  
2. Ensure the channel is not busy by pressing the   button momentarily. If audio is heard or if the   
icon is on, the channel is busy. 
3. When you’re sure that the channel is not busy, press the PTT button and speak into the microphone.
