2.1 RF EXPOSURE GUIDELINES
limits for occupational use, always adher e to the following guidelines:
• DO NOT operate the radio without a proper antenna attach ed, as this may d amage the radio an d may
also cause the FCC RF exposure limits to be exceed ed. A p roper anten na is the anten na supp lied with
this radio by Harris or an antenna specifically authorized by Harris for use with this radio. (Refer to
Table 7-1.)
• 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 . Th e rad io
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 (an tennas, batteries, bel t 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.)

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
Keep the antenna in a vertical position when r ecei ving 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
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,
regulations. (Refer to Table 7-1.)
3.1.2 Electronic Devices

5 BATTERIES
The P7300 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal
Hydride (NiMH), Lithium-Ion (Li-Ion), and Lithium Polymer batter ies. Please carefully read the battery
information provided to maximize the useful life of each type of battery.
Do not disassemble or modify Lithium ba ttery packs. The Lithium battery packs
are equipped with built-in safety and protection features. Should these feat ures be
disabled or tampered with in any way, the battery pack can leak acid, 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 th e affected area with water. If the battery
electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician
immediately.
Always use
and conditioners may void the warranty.
5.1 CONDITIONING BATTERY PACKS
5.1.1 Conditioning NiMH Battery Packs
Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging
and fully discharging the battery three (3) times using the tri-chemistry charger. The first time the battery
is put into the charger, this unit will condition Nickel-based battery packs by automaticall y 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 resu
shortened performance by the battery.
5.1.2 Conditioning NiCd Battery Packs
A new NiCd battery does not require conditioning before use. However, Harris recommend s periodically
conditioning NiCd batteries to avoid t he memory effect which results when a NiCd bat tery is repeatedly
charged and not fully discharged, further resulting in a lower voltag e and a lower capacity. Fortunately,
both nominal voltage and capacity are restored through battery conditioning.
Conditioning requires fully charging and fully discharging the battery three (3) times using the trichemistry charger. The first time the battery is put into the charger, this unit will condition Nickel-based
15
Page 16
MM-013994-001, Rev. J
battery packs by automatically chargi ng and discharging (cycling) the battery. Refer to the approp riate
charger manual for details.
5.1.3 Conditioning Lithium Battery Packs
Lithium-based battery packs do not suffer from memory effect and therefore do not require conditioning.
5.1.4 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, i ts overall capacity may be reduced. Although all battery
packs experience some capacity loss during storage, the shelf life for Li-Ion battery packs is about 3
months. However, note that any capacity drop which occurs during storage is permanent and cannot be
reversed. Li-Ion battery packs should be purchased and used immediately. They should not be stockpiled without a rotating stock plan.
5.1.5 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/.
5.2 CHARGING B ATTERY PACKS
Battery chargers are available fr om Harris with nominal charge times. Combination s 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 indefi nitely. For best results, l eave the battery in t he 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 lo w battery warning) before re-charging.
If any faults are encountered while charging the battery pack, con sult the charger’s manual to determine
the cause and possible corrective action.
5.3 BATTERY PACK USAGE
Both Nickel-based and Lithium batteries vary in capaci ty and life cycle. For instance, Ni Cd batt eries have
a longer life cycle than NiMH batterie s whereas NiMH batteries have a larger capacity. Howev er, both
Nickel-based and Lithium type batteries require basic usage g uidelines be followed in order to optimize
the battery runtime or shift life.

CAUTION
• Ensure Nickel-based battery packs are fully discharged (as indicated by the radio low battery
warning) before re-charging. Full discharge is not required for Lithium battery packs.
• Periodically condition Nickel-based battery packs. The frequency should be determined based on
usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning)
during routine use, the frequency of conditioning may be reduced. Lithium batteries do not suffer
from memory-effect and therefore do not require conditioning.
Do not leave any Harris rechargeable bat teries in a charger for more than a few days.

6 INTRODUCTION
The P7300 series portable radio is availabl e in two mo dels: th e P7350 Scan model wi th a li mited 6 -button
front-mounted keypad and the P7370 System model with a 15-button DTMF front-mounted keypad.
Figure 6-1: P7350 andP7370 Portable Radios
The Harris P7300 portable radio delivers end-to-end encrypted digital voice and IP data communications.
It is designed to support multiple operating modes including:
• EDACS
• OpenSky
®
(Enhanced Digital Access Communication s System) or ProVoice™ Trunked Modes
®
Trunked Protocol (OTP)
• P25 Trunked Mode
• P25 Digital Conventional Mode
• Conventional Analog Mode
The P7300 portables can include all of these modes or just one. Additional modes of operation can be
added with software updates.
The P7300 supports a full range of advanced digital trunking features, including Talk Group calls, priority
scanning, emergency calls, late call entry , and dynamic reconf iguration. It p erforms autonomou s roaming
for wide area applications. High quality voice coding and robust audio components assure speech clarity.
In the trunked modes, the user selects a communicati ons “operating” system (i.e., EDACS, ProVo ice, 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.
19
Page 20
MM-013994-001, Rev. J
In Conventional Analog mode, the user selects a ch annel and communicates directly on that chan nel. 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 P7300. Then refer
to the corresponding section(s) within this manual for feature and operation information.

Figure 9-6: Full Cycle Battery Charge Indicator
The battery charge indicator illustrates approximate charge only, based on battery voltage. Refer to
Figure 9-6.
9.2 TRI-COLOR L ED
Figure 9-7: 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 9-7).
In OpenSky mode the following radio states are ref l ected 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). I f the selected Talk Group is in the emergency
state, an asterisk will be displayed next to t he Talk Group name.
9.3 LOG-IN TO THE NETWORK
Log-in occurs either automatically (auto registration) if the radio has a valid registration or, if enabled,
requires the user to enter a User ID and password.
The user will be prompted with “Pls Login” if one Talk Group in the selected profile
can be encrypted. The user has to log-in to use that Talk Group in encrypted mode.
1. Press *1.
2. Enter the full 10-digit User ID.
3. Press the key.

in assistance and/or
NOTE
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 t he 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 alphanumeric passwords or once for numeric only passwords.
The User ID may be remembered from the previous log-in. (Refer to Section 9.4 for further details
regarding log-off commands.) The password will be established before the radio is put into operation.
Contact the local OpenSky network administrator for more information.
If necessary, contact radio system administration personnel for logradio-specific log-in instructions.
9.4 LOG OFF THE NETWORK
The *0## command de-registers the radio. Typically, this is automatically performed when powering
down the radio. Using this method, the User ID is remembered by the radio so only the password is
needed at next log-in.
If a user is logged in, it is preferable to log-o f f to prevent unnecessary network resources being used.
9.5 PERSONALITY
As illustrated in Figure 9-8, 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 comprehensiv e set of profiles to communicate effectively with the necessary
Talk Groups or individuals.
Personalities are stored on the network and downloaded over-the-air to the radio. This process is called
“provisioning.” Provisioning occurs at radio power-up (if the personality is not already stored in the
radio’s memory) and at user log-in (if the radio has been deregistered). When changes are made to the
personality, the radio is automatically re-provisioned. Each personality can contain up to sixteen (16)
profiles and each profile can contain up to sixteen Talk Groups.
9.5.1 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 ma de on the sel ected Talk Group (displayed on the top
line of the dwell display). The user ca n change the selected Talk Group to any of the other Talk Groups
within the profile.

9.5.2 Talk Groups
A Talk Group represents a set of users that regularly need to communicate with one an other. There can
be any number of authorized users assigned t o 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.
9.6 OPENSKY DISPLAY OVERVIEW
The 12-character x 3-line display shows the radio status. The first two lines of th e 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 9-3).
9.6.1 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 9-5). 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.
9.6.2 Display’s Second Line
The second line will display information su ch as activ e menu, log-in prompt, emergency status, and dwell
display messages as described in Section 9.6.3.
9.6.3 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 to p line indicates the curren tly selected Talk Group. The second line
will display the currently selected profile, caller ID/alias
if the channel menu is enabled. Press the button repeatedly to scroll through and view one of these
second line options.

9.14 DUAL-TONE MULTI-FREQUENCY (P7370 ONLY)
Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a
specific set of tone frequencies to each key . 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.
9.15 CHANGING T HE 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:

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 or use the Talk Group selection menu.
9.17 ADJUSTING DISPLAY AND BUTTON BACKLIGHT BRIGHTNESS
1. Press the or buttons until Bright Menu is displayed.
2. Use to toggle display backlighting on and to toggle display backlighting off.
9.18 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, and 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.

9.18.1 Enabling Stealth Mode
P7370 only: Quick Key combination 2# toggles Stealth Mode on and off.
Both models: Press the or buttons to scroll through menus until StealthMenu appears in the
display. To immediately activate Stealth Mode, press the or button once. This activates Stealth
Mode, exits the Stealth Menu, and returns to the Dwell Display.

P7350 only: To re-enable all lighting, side tones and exit Stealth Mode, press the or buttons or
the button. The radio returns to the Dwell Display.
The display lights, indicator lights, and side tones are re-enabled. The stealth mode icon disappears.
9.19 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, acces s 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.

As soon as the radio completes the initializatio n sequence an d registers o n the Open Sky network , the user
will begin to hear calls from the Talk Groups in the active profile, if available.
9.21.1 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 o r Fixed:
a. If the received Talk Group matches the select ed Talk Group, then the alias (if avai lable) 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 T alk 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 r eceiv ed , t he ali as ( if avail abl e) or t h e u ser
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.
9.21.2 Transmitting a Voice Call
1. Select the desired Talk Group.
2. Press and hold the PTT button, wait a couple of seconds. If programmed by the administrator, a
grant tone will sound.
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.
9.22 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 l evel. There are four levels available: low, mediu m, medium-
high, and high.
3. Press or wait a few seconds to return to the dwell display.

9.23 TALK GROUP L OCK OU T
There are two ways to focus voice communic ations by suppressing calls from Talk Groups in the active
profile.
• No Scan. By changing the Scanning Mode to No Scan only the selected Talk Group is scanned.
• Lock Out. By locking out selected Talk Groups, background noise or chatter can be eliminated and
scanning resources can be focused on just those groups whose calls you wish to monitor.
Lock out is a listening (receive) function and only blocks received calls on locked out
Talk Groups. Lock out does not affect transmit capability. “No Scan” and “Lock Out” do
not apply to recent emergency lock outs.
Only Talk Groups in the active profile can be locked out, since they are the only Talk Groups whose
voice calls can be heard on the radio. Talk Group lock out is a scan-related feature. With lock out, one or
more Talk Groups in the activ e profile can be temporarily disabled from being scanned. Call s are not
received on locked-out Talk Groups. Lock out settin gs 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.
9.23.1 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.
9.23.2 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.

9.24 SCANNING
9.24.1 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 radi o scans voice calls for all of the profiles in the radio per sonality,
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 selec tion may be limited by the administrator to a subset of the three
scanning modes.

Allows dragging of the select ed Talk Group, P1, P2, P3, and emer gency 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 emerg ency-enabled Talk Groups, is only dragged if it is in
emergency mode.
Functions the same as Normal Scan Mode, except the priority groups are fixed to the selected profile’s predefined 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

9.25 MAKING SELECTI VE CA LLS
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 co nfigu red to in itiate sele cti ve calls th roug h a pre-programmed list
in memory called a speed dial list. Alternatively, a prop erly configured radio can initiate a selective c all
to any radio in the system by ent ering the ten-digit User ID (similar to a telephone number) of the tar get
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 physical registration, No Priv is displayed.
9.25.1 Manually Dialing a Selective Call (P7370 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 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 ap pear 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.

9.26 SELECTIVE ALER TS
Selective alert messaging is an OTP feat ure that allows one of up to eight (8) pre-programmed (canned)
text messages to be sent from one radio to another. The sender speci fies 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 th e radio until deleted or until t he radio is reboo ted. Received messages
do not survive a reboot.
9.26.1 Defining Messages
All selective alert messages are pre-defined. The messages are programmed and provisioned remotely by
your OpenSky system administrator. Th e radio user cannot create selective alert message content. The
entire selective alert message, including the abbreviation, can be up to 99 characters long.
Table 8-10 lists and defines the messages that may be displayed by the radio during a Selective Alert.

9.28 EMERGENCY COMMUNICATIONS
The P7300 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.

9.28.1 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 E mergency button sends an Emergen cy Call o r 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 u nsuccessful, “E-PE ND” flashes period ically and a retry is queued for 10 seconds. If the
attempt is unsuccessful because of lost syn c, retry occurs immediately upon reacquiring sync. On each
retry attempt, radio temporarily displays “E-RETRY.” This process repeats until the emergency is
successfully declared.
9.28.2 Receiving an Emergency Call
Initially, when receiving an emergency call, the radio sounds the emergency tone (three short highpitched tones).
The radio will flash EMERGENCY and display the alias of the user th at tr iggered th e emergen cy or th e 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 9.28.3.
9.28.3 Dismissing an Emergency
The “Dismissing an Emergency” funct ion 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.

9.29 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 o f C ommerce 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., P7300 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 v oice, any listening users with different encryption keys
hear distorted voice and No Access appears in the radio display.
9.29.1 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 identif ied as secure, credentials for
key generation are generated automatically by the system and provisioned to authorized users. This
process requires that authorized users log-in 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.
If enabled via programming, a radio can automatically log-in
enable voice encryption.
50
Page 51
MM-013994-001, Rev. J
NOTE
To use automatic encryption:
1. Locate the Talk Group that has been encrypted at the system administrat or level.
2. Pls Login appears in the display (un l ess the keypad was used to log-in).
3. Log-in normally by entering your User ID and Password.
If a user is engaged in a call on a Talk Group encrypted at the network administrator level, Secure Call
will appear in the second line of the dwell display if the user is logged in to 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.
9.29.2 A/B Switch
If configured, the A/B switch can be used to enable or disable encryption.
9.29.3 Manual Encryption (P7370 Only)
Two or more users can manually encrypt a call, if enabled, witho ut an established encry pted Talk Group.
A pre-determined “key or code” is required. No te that while a user is engaged in an encryp ted call, user s
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 curren tly selected Talk Group. All available Talk Groups within the
current profile may be independently encrypted.
The key must be pre-determined by the users prior to making a manually encrypted call on
a Talk Group and is entered into the radio using the keypad. For 128 bit encryption, this
key is between 1 and 16 digits. For 256 bit encryption, this key is between 17 and 32
digits.
9.29.3.1 Using Manual Encryption
1. Press *32 on the keypad.
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).
3. Press #.
4. To end manual encryption, press *33.
If a user is engaged in a call on a Talk Group that has b een manu ally encry pted at the rad io lev el, th e 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 en cry ption, UnSecure appears temporarily in the bottom line of the
dwell display.

9.32 SITE LOCK
Users may need to select the site in cases wher e netwo rk co mmunicatio ns are do wn. Th e Site Lo ck menu
allows a user to manually roam to a specific site. T he sites in the menu are populated with the current
site, adjacent sites, and node 2 sites. The menu allows t he user to select a particu lar 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 sit e. 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.

9.34 V-TAC OPERA TION
9.34.1 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) function ality 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).
53
Page 54
MM-013994-001, Rev. J
Typically, Extended Coverage is used a fter the vehicle’s operator has exited the vehicle with a p ortable
radio unit and the portable unit requires this bridging functionality to access the OpenSky radio network.
The V-TAC takes advantage of OpenSky’s T DMA 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 syst ems. 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 cli ents. 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 VTAC running version OTP14.3.1 or earlier, the client displays “VA None.”
9.34.2 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.
9.34.3 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.
9.34.3.1 Limitations Using XCOV, XCOV-TG, and XCOV-PROF
Portable radios connected to the V-TAC using any of the Extended Coverage Modes, XCO V, 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 netwo r k channels.
9.34.3.2 Limitations Using XCOV-TG
The following portable radio keypad functions are disabled when the radio is connected to the V-TAC
using the XCOV-TG mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and speed dial
calls, SOI mode, RTT.
The following portable radio menus are disabled when the radio is connected to the V-TAC using the
XCOV-TG mode: alert destination, alert message, alert received, channel, speed dial, priority 1 Talk
Group, priority 2 Talk Group, priority 3 Talk Group, RTT, Status message, site lock and scan mode. In
addition, the user cannot change Talk Group or profile.
9.34.3.3 Limitations Using XCOV-PROF
The following portable radio keypad functions are disabled when the radio is connected to the V-TAC
using the XCOV-PROF mode: log-off, manual log-in, alerts, selective calls, PSTN calls, and sp eed dial
calls, SOI mode, RTT.
54
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.
Page 55
MM-013994-001, Rev. J
9.34.4 Use XCOV Mode
The Extended Coverage for individual users (XCOV) mode allows up to eight (8) client radios to connect
to the V-TAC. The radios have full radio functionality including selective calling and mobile data.
With the Extended Coverage for individual users’ (XCOV) mode, V-TAC configuration defines which
portable radios are permitted V-TAC access. The radio will automatically connect to a V-TAC if it
cannot find a network channel. The radio can also be manually connected to a V-TAC as indicated with
the *61# and *62# commands, each determined by the system administrator in the radio configuration.
9.34.4.1 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.
9.34.5 Use XCOV-TG Mode
When using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. However,
unlike XCOV, radios connected using XCOV-TG a re limited to communicating only on the XCOV-TG
Talk Group. The radio can only raise an emergency if this Talk Group is emergency capabl e. Advanced
features such as selective callin g 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 c ommunications is the Talk Group that was selected at the V-TAC
when it entered XCOV-TG mode. Befo re 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.
9.34.5.1 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#).

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.
9.34.6 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 an d receip t of voice ca lls 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 VTAC while allowing flex ibility of voice fun ctionality. As a resul t, data services between the client and VTAC are disabled. The radio will automatically connect to a V-TAC if it cannot find a network channel.
Note the following regarding XCOV-PROF mode:
• The client profile must match the V-TAC.
• The client profile used to connect to the V-TAC must have been previously provisioned to the client
prior to connection. If the profile is not in the client’s personality, the client cannot connect to the VTAC.
• Neither the V-TAC nor a client can change the profile once it h as entered XCOV-PROF mode. The
Profile menu will be disabled.
• Client global profiles are disabled.

10.21.1 Wide Area System Scanning
The P7300 series radio can be pre-programmed through RPM for Wide Area System Scan operation for
roaming across mobile systems. ED ACS radio systems manage the radios assi gned to the system via a
control channel (CC). Upon the loss of the currently selected system's control channel, radios can be
programmed to automatically scan the control channels of other systems. If a new control channel is
found, the radio will switch to the new system and sound an alert tone.
10.21.2 Priority System Scan
The radio can also be pre-programmed for Priority System Scan. The priority syst em is the desired or
preferred system. While receiving the control channel of the selected system, the radio will period ically
leave the selected system and search for the cont rol channel of the priority system. This is done at a preprogrammed rate defined by th e valu e in th e Pri orit y Scan Ti me control, unless the ProScan

10.21.2.1 Enabling the Wide Area System Scan Function
If the radio cannot find the control channel o f 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.
10.21.2.2 When ProScan is Enabled
The radio monitors the priority system and will switch to the priority system if the pre-preogrammed
criteria ProScan options are met. If ProScan is enabled, the rate at which the radio will scan for the
priority system is defined by the System Sample Time control, set in RPM (refer to RPM On-Line Help).
See Section 10.21.3 for more information on ProScan.
10.21.3 ProScan
The radio may be programmed for ProScan system scan operation for multi-site applications. ProScan is
a multi-site, system-scanning algorithm. ProScan provides the radio with the ability to select a new
system for the radio to communicate on, when the selected system drops below a predefined lev el. This
algorithm enables each radio to analyze the signal quality of its current control channel and compare it
with the signal quality of the control channel for each site in its adjacent scan list. The signal quality
metric used for the ProScan algorithm is based on a combination of both Received Signal Strength
Indicator (RSSI) and Control Channel Verification (CCV) measurements. When the selected system
degrades to a pre-programmed level, the radio will begin to look for a better control channel. Once a
control channel that exceeds the pre-programmed parameters is found, the radio will change to the new
system and emit a tone (if enabled through programming). If the control channel is completely lost, the
77

radio will enter Wide Area System scan ning and search the prog rammed adjace nt systems un til a suitabl e
control channel is found.
10.22 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 emergenc y
has been cleared.
10.22.1 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.
10.22.2 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 ra dio will transmit an emergency call request with th e 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 10-5) and is ready for voice transmissi on. *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 co mplete.
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.)
10.23 STEALTH MODE
Press the button programmed for Stealth Mode operation to toggle Stealth Mode on or off. During Stealth
Mode, all buttons are disabled except PTT, the button programmed for Stealth operation, Emergency, and
Nuisance delete. The radio will receive and transmit when Stealth Mode is enabled.
The radio can be configured to disable any or all of the following during Stealth Mode:
• LCD display
• LED
• Backlight
• Side/alert tones
Stealth Mode can be configured to persist t hrough a power cycle.

10.24 INDIVIDUAL CALLS (EDACS AND P25 MODES)
10.24.1 Receiving and Responding to an Indi vi dual 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 th e originating unit. If a response is not made before the cal l-back timeout, 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 Receiv ed 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.

10.25.3 Dual-Tone Multi -Frequency: Overdial
Once the radio has established a connection to th e public telephone system, it may be necessary to “ov erdial” 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 interco nnect call via DTMF signaling if a dial
tone has already been accessed on the sy stem. 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.

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.
10.28 DYNAMIC REGROUP OPERATION (EDACS)
Dynamic Regroup Operation permits multiple Talk Groups (up to eight) to be added to a radio via the
system manager. The radio must be pre-programmed to respond to regrouping. Dynamic regrouping will
not be activated in a radio u ntil the sy stem manager sends an activat ion messa ge. Each r adio that receive s
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.
10.28.1 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.
10.29 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 t o ch ang e the k ey st roke sequen ce th e n ext ti me the macro k ey
is activated.
For detailed operation and assignment of macro keys, contact your communications supervisor or
administrator.
10.30 DATA ( EDACS AND P25 MODES)
The P7300 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 o f 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 Dat a Interface (RDI ) protoco l (Version 1.9 1 or greater) may b e

Additionally, radios may also be programmed for data only operation (no voice calls transmitted or
received).
10.30.1 Displays
The following will be displayed during data operation:
en the radio is transmitting/receiving a data call.
10.30.2 DATA OFF Oper at ion
The radio can be placed in the data disab led state b y any of the fol lowing metho ds. When th e data state i s
disabled, DATA OFF appears on the top line of the display.
• Declaring an emergency (not to be used unless an actual e mergency conditi on 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.
10.30.3 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.
10.30.4 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 pr e-programmed emergency button.
• If a group or system is changed.
10.30.5 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.
86

• Declare or clear an emergency.
• Receive an individual or phone call.
• Receive an Agency, Fleet, or System All Call.
• Press (P7350 model) or (P7370 model) to toggle Scan ON or OFF.
10.30.6 Data Lockout Mode
During the voice call scan hang time (pre-programmed) the radio does not r eceive data calls.
10.31 TYPE 99 OPERATION (ANALOG CONVENTIONAL)
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 P7300 portable radios operate in one of two states, Monitor
mode or Selective Call mode.
• In Monitor mode, Type 99 “OFF,” the decod er is disabled and all calls are heard by the user.
• In Selective Call mode, Type 99 “ON,” the d ecoder is enabled and only calls intended for the user
will be heard.
10.31.1 Type 99 with or without Channel Guard
Selective signaling operates with or witho ut Channel Guard. If Channel Guard is enabled, the rad io 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 th at rec eiv es 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.
10.31.2 Resetting Type 99 after a Cal l
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.
87
Page 88
MM-013994-001, Rev. J
NOTE
• Allow the "Auto-Reset" timer, if enabled through programming, to reset the Type 99 decoder.
10.31.3 Type 99 Disable after PTT
The radio may be programmed with the Type 99 Disab le after PTT feature, which auto matically disables
the Type 99 decoder after a transmission.
Use one of the methods outlined in Section 10.31.2 to reset Type 99 operation.
10.32 AUDIO PLAYBACK
Every call received by the radio is recorded in internal memory, overwriting the last recorded call. When
the PLAYBACK key is pressed, the last recording is replayed and any future recordings are stopped.
Pressing PLAYBACK again repeat s the same recorded call. Pressing and holding the PLAYBACK key
until the tone sounds erases the recording and starts the recording of incoming calls again. If a call is
received while the recorded call i s playing, the recorded call continues to p lay, rather than the received
audio. However, if a call is received and the recorded call is played back in close succ ession received
audio could mute call playback. This feature requires RPM R8A and later, and ECP R15A and later.
The PLAYBACK function must be programmed to a button on the radio via RPM.
10.33 RADIO TEXTLINK OPERATION

2. Press or to scroll through menu until GPS is displayed and press to select.
3. Press or to scroll through available information screens.
10.35 CONTROL AND STATUS SERVICES
The P7300 supports Control and Status services. These services allow the computer application to
monitor and control a radio. The Control and Status Services can be used from a locally-connected
Mobile Data Terminal (MDT) or a network MDT. In some cases, the radio can support both MDTs
simultaneously. However, priority is given to the local MDT.
The Radio Status Service allows an MDT or Fixed End System (FES) to receive real-time status upd ates
from a radio. An MDT sends Host Att ach/Detach messages to the radio as UDP datagra ms destined for
the UDP Service Address and Serv ice UDP Port of the radio. All respo nses and asyn chronous reports are
returned to the address and port of the requesting host. Refer to the ECP Control and Status Services
