2 SAFETY TRAINING INFORMATION
The Harris P7300 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 P7300 portable radio has been tested and complies with the FCC RF exposure limits for
“Occupational Use Only.” In addition, this Harris 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 Harris or an antenna specifically authorized by Harris for use with this radio. (Refer to
Table 6-1.)
• DO NOT transmit for more than 50% of total radio use time (“50% duty cycle”). Transmitting more
than 50% of the time can cause FCC RF exposure compliance requirements to be exceeded. The radio
is transmitting when the “TX” indicator appears in the display. The radio will transmit by pressing the
“PTT” (Push-To-Talk) button.
• Always transmit using low power when possible. In addition to conserving battery charge, low power
can reduce RF exposure.
• ALWAYS use Harris authorized accessories (antennas, batteries, belt clips, speaker/mics, etc). Use of
unauthorized accessories may cause the FCC Occupational/Controlled Exposure RF compliance
requirements to be exceeded. (Refer to Table 2-1.)
MM-013994-001, Rev. Ap1
14
• As noted in Table 2-1, ALWAYS keep the device and its antenna AT LEAST 1.1 cm (0.43 inches)
from the body and at least 2.5 cm (1.0 inch) from the face when transmitting to ensure FCC RF
exposure compliance requirements are not exceeded. However, to provide the best sound quality to
the recipients of your transmission, Harris recommends you hold the microphone at least 5 cm (2
inches) from mouth, and slightly off to one side.

The information in this section provides the information needed to make the user aware of RF exposure,
and what to do to assure that this radio operates within the FCC RF exposure limits of this radio.
2.2 ELECTROMAGNETIC INTERFERENCE/COMPATIBILITY
During transmissions, this Harris radio generates RF energy that can possibly cause interference with
other devices or systems. To avoid such interference, turn off the radio in areas where signs are posted to
do so. DO NOT operate the transmitter in areas that are sensitive to electromagnetic radiation such as
hospitals, aircraft, and blasting sites.
MM-013994-001, Rev. Ap1
15
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 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-013994-001, Rev. Ap1
16
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-013994-001, Rev. Ap1
17
4 BATTERIES
The P7300 series portable radios use rechargeable, recyclable Nickel Cadmium (NiCd), Nickel Metal
Hydride (NiMH), or Lithium Ion (Li Ion) batteries. Please read carefully, the battery information
provided, to maximize the useful life of each type of battery.
Do not disassemble or modify Lithium Ion battery packs. The Lithium Ion battery
packs are equipped with built-in safety and protection features. Should these
features be disabled or tampered with in any way, the battery pack can leak 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 the affected area with water. If the battery
electrolyte gets in the eyes, flush with water for 15 minutes and consult a physician
immediately.
4.1 CONDITIONING BATTERY PACKS
4.1.1 Conditioning NiMH Battery Packs
Condition a new NiMH battery before putting into use. This also applies to rechargeable NiMH batteries
that have been stored for long periods (weeks, months, or longer). Conditioning requires fully charging
and fully discharging the battery three (3) times using the tri-chemistry charger. The first time the battery
is put into the charger, this unit will condition Nickel-based battery packs by automatically charging and
discharging (cycling) the battery. Refer to the appropriate charger manual for details.
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, Harris recommends periodically
conditioning NiCd batteries to avoid the memory effect which results when a NiCd battery is repeatedly
charged and not fully discharged, further resulting in a lower voltage 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 tri-
chemistry charger. The first time the battery is put into the charger, this unit will condition Nickel-based
battery packs by automatically charging and discharging (cycling) the battery. Refer to the appropriate
charger manual for details.
MM-013994-001, Rev. Ap1
18
CAUTION
Always use Harris 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.
4.2 CHARGING BATTERY PACKS
Battery chargers are available from Harris with nominal charge times. Combinations include single and
multi-position charge units.
Harris chargers are specifically designed for charging nickel-based and lithium ion 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.
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 Harris battery packs using a charger approved for use by Harris.
• Do not leave batteries in the charger indefinitely. For best results, leave the battery in the charger for
two to six hours after the Green Ready LED comes on. Then place the battery pack into service and
fully discharge (as indicated by the radio low battery warning) before re-charging.
If any faults are encountered while charging the battery pack, consult the charger’s manual to determine
the cause and possible corrective action.
4.3 BATTERY PACK USAGE
Both Nickel-based and Lithium ion batteries vary in capacity and life cycle. For instance, NiCd batteries
have a longer life cycle than NiMH batteries whereas NiMH batteries have a larger capacity. However,
both Nickel-based and Lithium ion type batteries require basic usage guidelines be followed in order to
optimize the battery runtime or shift life.
4.3.1 Usage Guidelines
The following guidelines will help optimize the battery runtime or shift life:
• Ensure Nickel-based battery packs are fully discharged (as indicated by the radio low battery
warning) before re-charging. Full discharge is not required for Lithium Ion battery packs.
• Periodically condition Nickel-based battery packs. The frequency should be determined based on
usage patterns (refer to ECR-7367). If the battery is fully discharged (to radio Low Battery warning)
during routine use, the frequency of conditioning may be reduced. Lithium Ion batteries do not suffer
from memory-effect and therefore do not require conditioning.
MM-013994-001, Rev. Ap1
19
Do not leave any Harris rechargeable batteries in a charger for more than a few days.
4.4 CHANGING THE BATTERY PACK
4.4.1 Removing the Battery Pack
Make sure the power to the radio is turned OFF.
CAUTION
Although the P7300 has been designed to tolerate changing the battery pack without
turning power off, Harris recommends turning the radio off before changing battery packs
to ensure safety and best operation.
1. Press or pull both latches on either side of the battery pack toward the bottom of the radio
simultaneously.
2. Pull the battery away from the radio.
3. Remove the battery pack from the radio.

5 INTRODUCTION
The P7300 series portable radio is available in two models: the P7350 Scan model with a limited 6-button
front-mounted keypad and the P7370 System model with a 15-button DTMF front-mounted keypad. The
UHF P7300 portable radio delivers end-to-end encrypted digital voice and IP data communications. It is
designed to support multiple operating modes including:
• EDACS® (Enhanced Digital Access Communications System) or ProVoice™ Trunked mode
• 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 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., EDACS, ProVoice, or
P25) and group. While communicating in a trunked mode, channel selection is transparent to the user and
is controlled via digital communication with the system controller (e.g., a CSD in an EDACS system).
This provides advanced programmable features and fast access to communication channels.
In Conventional Analog mode, the user selects a channel and communicates directly on that channel. A
channel is a transmit/receive radio frequency pair.
The exact operation of the radio will depend on the operating mode, the radio’s programming, and the
particular radio system. Most features described in this manual can be enabled through programming.
Consult your System Administrator for the particular features programmed into your P7300. Then refer
to the corresponding section(s) within this manual for feature and operation information.
5.1 WATER RESISTANCE
The P7300 series portable radios operate reliably even under adverse conditions. These radios meet MIL-
STD-810F specifications for wind driven rain, humidity, and salt fog.

8.1 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 P7350 Scan model and 15 buttons on the P7370 System Radio.
8.1.1 Buttons and Knobs
This section describes the primary function of the button and knob controls (see Figure 7-2 and Figure
7-3). Other functions associated with these controls are detailed in later sections.
POWER ON/OFF-VOLUME
CONTROL 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 40, which is the loudest level.
SYSTEM/GROUP/CHANNEL
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 System/Group/Channel control knob, loosen the set
screw on the System/Group/Channel control knob metal base (using a
1.27 mm hex wrench), and remove the System/Group/Channel control
kno
b
metal base. Replace the 16 channel ring with the channel stop ring
located at the desired channel. Reinstall the System/Group/Channel
control knob metal base, tighten the set screw, and reinstall the
System/Group/Channel control knob.
EMERGENCY/HOME BUTTON Automatically selects the pre-programmed Group/System by pressing
and holding for a programmed duration. It can also be used to declare
an emergency by pressing and holding for a programmed duration. The
button must be pre-programmed for either operation, but not both.
PTT BUTTON PTT must be pressed before voice transmission begins. In trunked mode
the radio’s ID is transmitted upon depression of the PTT button.
OPTION BUTTON Activates one of a number of programmable software options selected
during PC programming. Programmable options include hi/low power
settings, keypad lock, LCD contrast, LCD and keypad back lighting.
CLEAR/MONITOR BUTTON
OPTION BUTTON 2 Exits the current operation (removing all displays associated with it)
and returns the radio to the selected talk group. Terminates individual
and telephone interconnect calls.

8.18 DIGITAL VOICE OPERATION
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system
and on a per-channel basis within each conventional system.
MM-013994-001, Rev. Ap1
49
8.18.1 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 or
private messages.
8.18.2 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 or
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.
1. If receiving an analog message trunked call, the radio responds in the analog mode during the
hang time on the working channel.
2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time.
3. 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.
8.18.3 Private Mode
The Private Mode allows the radio to transmit encrypted messages and receive clear or private
transmissions. The radio transmits private if the group/channel is programmed for private operation and
forced operation is pre-programmed. If auto-select operation is pre-programmed and the radio is in the
Private Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang
time is active, the radio transmits private.
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7)
different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio.
An individual key is automatically selected on a per-group/channel basis according to the radio
programming. Groups and channels within the digital system can be programmed for keys 1-7 (private).
Up to 8 banks of 7 keys can be stored for private systems. The bank is specified per system.
When operating on a group or channel programmed for Private Mode, all transmissions are private
transmissions and the radio receives clear and private signals. The status icon is displayed when the
Private Mode is enabled. If the selected group or channel is programmed for auto-select capability, the
mode may be toggled between private and clear with the key, then following the selection mode
rules. Radios programmed for forced private operation do not allow a change of the transmit mode.

8.18.3.2 Key Zero
All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while still
pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of
beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been
zeroed. The display will indicate KEY ZERO.
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the
radio before private communications may continue.
8.18.4 Private Operation
8.18.4.1 Receiving an Encrypted Call
When receiving, the radio automatically switches between clear or private operation. If the transmission
being received is an encrypted transmission, it will be decrypted, the icon will be displayed, the receiver
will unsquelch, and the message will be heard in the speaker. For this to occur, the selected group or
channel must be programmed for private operation and the correct cryptographic key must be loaded into
the radio.
8.18.4.2 Transmitting an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in Private Mode by pressing key; then follow the selection mode rules. On a
System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is
enabled, the icon is displayed.
MM-013994-001, Rev. Ap1

3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also,
the Private Mode will be enabled if forced operation has been programmed in the radio.
If a group or channel is not programmed for Private Mode operation, PVT DIS will be displayed if
an attempt is made to enable private transmit mode. It is not possible to operate on this group/channel
in Private Mode.
If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call
will not be transmitted.
4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the
PTT button is pressed.
8.18.4.3 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 auto-select, 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 private and entered in the scan list, it can receive clear and private calls, provided
auto-select 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 under different modes, (clear, digital, or
private), then only the first occurrence of the group will be used.

OFF and then powered ON.
8.20 SCANNING TRUNKED SYSTEMS
The radio can be programmed using Radio Personality Manager (RPM) with the following System Scan
features. Then these features are automatically enabled when the radio is powered ON. A key or menu
option is also defined to allow the System Scan features to be toggled during radio operation. The System
Scan state will be maintained through system changes but will default to ON when the radio is powered
ON.
Enable/Disable via Menu Selection
Press and then use the or buttons to scroll through the selections until SYS SCAN is
displayed. Then press to toggle the System Scan state. The SYSC ON or SYSC OFF display
message is displayed for two seconds to show the new state.
Enable/Disable via Pre-Programmed Keypad Key
Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message
is displayed for two seconds to show the new state.
8.20.1 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. EDACS radio systems manage the radios assigned to the system via a
control channel (CC). Upon the loss of the currently selected system's control channel, radios can be
programmed to automatically scan the control channels of other systems. If a new control channel is
found, the radio will switch to the new system and sound an alert tone.
8.20.2 Priority System Scan
The radio can also be pre-programmed for Priority System Scan. The priority system is the desired or
preferred system. While receiving the control channel of the selected system, the radio will periodically
leave the selected system and search for the control channel of the priority system. This is done at a pre-
programmed rate defined by the value in the Priority Scan Time control, unless the ProScan™ algorithm is
enabled, as explained in the following sections. This priority scan timer is reset each time the PTT button
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.
8.20.2.1 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.
MM-013994-001, Rev. Ap1
55
8.20.2.2 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 8.20.3 for more information on ProScan.
8.20.3 ProScan
The radio may be programmed for ProScan system scan operation for multi-site applications. ProScan is
a multi-site system scanning algorithm. ProScan provides the radio with the ability to select a new
system for the radio to communicate on, when the selected system drops below a predefined level. This
algorithm enables each radio to analyze the signal quality of its current control channel and compare it
with the signal quality of the control channel for each site in its adjacent scan list. The signal quality
metric used for the ProScan algorithm is based on a combination of both Received Signal Strength
Indicator (RSSI) and Control Channel Verification (CCV) measurements. When the selected system
degrades to a pre-programmed level, the radio will begin to look for a better control channel. Once a
control channel that exceeds the pre-programmed parameters is found, the radio will change to the new
system and emit a tone (if enabled through programming). If the control channel is completely lost, the
radio will enter Wide Area System scanning and search the programmed adjacent systems until a suitable
control channel is found.
8.21 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.
8.21.1 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.
8.21.2 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 8-4) and is ready for voice transmission. *TXEMER* flashes on line two in
the display until the emergency is cleared.
3. Press PTT and speak into the microphone in a normal voice. and momentarily turn ON.
4. Release PTT when the transmission is complete.
To clear the emergency, first press and hold the button. While continuing to hold the button, press
the EMERGENCY button. (This will work if the radio is programmed to clear emergencies.)

8.22 INDIVIDUAL CALLS
8.22.1 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.

8.23.3 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.
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.

8.25 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 8.25.1).
8.25.1 Status Operation
P7370 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.

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.
8.26 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
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.
8.26.1 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.
8.27 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.
8.28 PORTABLE DATA
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;
MM-013994-001, Rev. Ap1
63
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).
8.28.1 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.
DATA ON Appears for two seconds on top line of display when the radio is toggled to the data
enabled state.
8.28.2 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.
8.28.3 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.
8.28.4 Exiting Data Calls
Under normal conditions, the radio enters the scan lockout mode and returns to the control channel after
completion of a data call (transmit or receive). If, during a data call, one of the following operations
occurs, the data call is immediately terminated and the radio performs the desired function:
• If the PTT is activated.
• If an Emergency is declared by pressing the pre-programmed emergency button.
• If a group or system is changed.
8.28.5 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
MM-013994-001, Rev. Ap1
64
call and one after a transmitted data call. During this time the scan indicator will flash to indicate that scan
is enabled but temporarily suspended. This condition typically returns to normal scan operation when the
pre-programmed time expires; however, the following operations and conditions will terminate the scan
lockout mode before the timeout has expired.
• Press the button.
• Press the PTT.
• Change a group or system.
• Enter Telephone Interconnect mode.
• Enter Individual call mode.
• Receive a new emergency assignment.
• Declare or clear an emergency.
• Receive an individual or phone call.
• Receive an Agency, Fleet, or System All Call.
• Press (P7350 model) or (P7370 model) to toggle Scan ON or OFF.
8.28.6 Data Lockout Mode
During the voice call scan hang time (pre-programmed) the radio does not receive data calls.

9 OPENSKY OPERATION
Once an OpenSky system has been selected from the available systems on your P7300 series portable
radio, the characteristics described in the following sections will govern operation.
9.1 CONTROLS
The P7300 portable radio features two rotary control knobs, an emergency button, and a dual-position
A/B switch located on the top of the radio. Refer to Figure 7-2. The Push-To-Talk (PTT) button and two
option buttons are located to the left side of the radio keypad, see Figure 7-3. The front mounted keypad
of the P7370 “System” model has 15 buttons and the P7350 “Scan” model has six buttons. Refer to
Figure 7-4 and Figure 7-5, respectively.
9.1.1 Buttons and Knobs
The function of the button and knob controls will vary depending on the mode of operation. The primary
functions of the button and knob controls when in the OpenSky mode of operation are listed in the
following paragraphs.

9.3 TRI-COLOR LED
Figure 9-2: 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 9-2). The radio states reflected by the LED are:
Green: Receiving
Red: Transmitting
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.
9.4 LOG IN TO THE NETWORK
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled,
requires the user to enter a User ID and password.
The user will be prompted 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.
The User ID may be remembered from the previous log-in. (Refer to Section 9.5 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.
MM-013994-001, Rev. Ap1
71
If necessary, contact radio system administration personnel for log-in assistance and/or
radio-specific log-in instructions.
9.5 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, it is necessary to log-off.
9.6 PERSONALITY
As illustrated in Figure 9-3, 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.
9.6.1 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.

9.6.2 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.
9.7 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 9-2).
9.7.1 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 9-4). 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.
9.7.2 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.
9.7.3 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.
MM-013994-001, Rev. Ap1
73
9.8 ALERT TONES
The P7300 radio also provides audible Alert Tones or “beeps” to indicate the various operating conditions
(see Table 9-3).
Table 9-3: Alert Tones
NAME TONE DESCRIPTION
Call Queued one low tone/two high tones Call is queued for processing.
Call Denied three short beeps Radio is out of coverage area or requested talk group is active.
Grant (or Go-Ahead) single short beep Sounded when resources become available for a call request
placed in the queue (if enabled) upon channel access.
If the radio roams to another site while transmitting, then it
will auto rekey and begin transmitting on that tower. It gives a
second grant tone to let the user know they have roamed.
Call Removed single long low-pitched tone Notifies the user access to the channel has been lost (out of
coverage area or pre-empted by higher-priority call).
Low Battery one low-pitched/one short mid-
pitched Low battery
Selective Alert Received four short tones Only played once to indicate a selective alert has been receive.
Emergency Alert Tone three long beeps Sounds when an emergency alert is declared.
Emergency Cleared Tone one long low-pitched tone Sounds when an emergency is cleared.
Selective Call Ring Tone a ringing tone similar to a
telephone Ringing is repeated every four (4) seconds until the call is
accepted or rejected by the radio being called or until the
network drops the call if unanswered after one (1) minute.
Roam Tone two short tones, one high-
pitched and one low-pitched Sounds when the radio transitions from one radio base station
site to another.
Out of Range Tone three brief tones If enabled via programming, sounds at a programmable
interval while the radio is in a state of persistent deactivation.

If the radio is in Stealth mode, this quick key is disabled since the user is not able to turn on
the light/tones in stealth mode.
6#
XCOV & XCOV-TG Attach/Detach
This quick key sequence is used to manually connect to a V-TAC. When attaching to a
V-TAC, the radio’s programming determines whether to attach to the V-TAC in XCOV or
XCOV-TG mode.
1. If the user attaches to a V-TAC manually, using the *61# or *62# command sequence, the
radio is understood to be attached and this quick key sequence will detach the radio from
the VTAC.
2. If the user detaches manually from a V-TAC using the *60# command sequence, the radio
is understood to be detached and this quick key sequence will attach the radio to a VTAC.
3. At bootup, the radio is understood to be detached from a VTAC. If a radio automatically
attaches to a VTAC, the radio is still understood to be detached from a VTAC and will
attempt to attach to a VTAC.
4. If a radio manually attaches to a VTAC and then is automatically detached from a VTAC, the
radio is still understood to be attached to a VTAC and will attempt to detach from a VTAC.
9.12 LOCK/UNLOCK THE KEYPAD

9.17.3 Stealth Mode using A/B Switch
It is also possible to enable and disable Stealth Mode using the A/B Switch, if so programmed.
Depending on programming the switch in one position will enable Stealth Mode and in the other position,
disables it.
With Stealth Mode on the P7350 model radio, pressing any radio button (other than
the mic’s PTT button or the Emergency button) on the front panel will immediately
turn Stealth Mode off. For example, pressing the button on the front panel will
turn stealth mode off.
9.18 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.
9.19 CHANGE OPERATING MODE
1. Press the or buttons to cycle through the menu until “Mode Menu” is displayed.
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.
9.20 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.
9.20.1 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.
9.20.2 Transmitting a Voice Call
1. Select the desired talk group.
MM-013994-001, Rev. Ap1
80
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.
9.21 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.
9.22 TALK GROUP LOCK OUT
There are two ways to focus voice communications by suppressing calls from talk groups in the active
profile.
• Non. By changing the Scanning Mode to “None” 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. “None” and “Lock Out” do not
apply to recent emergency lock outs.
Only talk groups in the active profile can be locked out, since they are the only talk groups whose voice
calls can be heard on the radio. Talk group lock out is a scan-related feature. With lock out, one or more
talk groups in the active profile can be temporarily disabled from being scanned. Calls are not received on
locked-out talk groups. Lock out settings are not retained between profile changes or when the radio is
power cycled.
If the Scan Mode is “Fixed,” P1 and P2 groups CANNOT be locked out. See Section 9.23
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.
MM-013994-001, Rev. Ap1
81
9.22.1 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.
9.22.2 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.
9.23 SCANNING
9.23.1 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-013994-001, Rev. Ap1
82
Table 9-7: Scan Modes
SCAN
MODE EXPLANATION
None

• The scanning priority settings are reset to the default values when the radio is turned
off.
9.24 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.
9.24.1 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>#
<destination user id>
MM-013994-001, Rev. Ap1
84
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.
9.24.2 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.
9.24.3 Accepting a Selective Call
1. The radio will ring (like a telephone), indicating you are receiving a Selective Call.
2. Press the , or the or buttons to accept the incoming selective call.
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.
9.24.4 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 or the key, or by turning the Voice Group Selector Control knob. The call will be
rejected and “Reject” appears on the callers display.
MM-013994-001, Rev. Ap1
85
9.24.5 Terminating a Selective Call
Terminate a Selective Call (call must be active) by pressing the or buttons or the key, or by
turning the Voice Group Selector Control knob. “HANGUP” will appear in the display followed by the
active talk group.
9.25 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.
9.25.1 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 9-8).
Table 9-8: 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
Delivered Transmission complete
Unreachable No response
Partial Transmission interrupted
9.25.2 Sending a Message
The sending process has three steps. First select the destination radio’s User ID, then select the alert
message, and finally send the message.
9.25.2.1 Selecting a Destination Using the Keypad (P7370 Only)
1. Using the keypad, enter *7, the keys.
At the “AlertDst” prompt, enter the full User ID of the unit to send the message. 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.
MM-013994-001, Rev. Ap1
86
• If the radio being called is in another region or if the area is unknown – enter all ten digits.
2. Press the key to activate the selection.
3. Use the and buttons or the and buttons to scroll through the available messages until the
desired message is displayed.
4. Press the or key to send the message.

4. Press the key to send the message.
5. Observe Status Messages (Table 9-8) to ensure proper delivery.
9.25.3 Receiving a Message
When a selective alert message is received by a radio, a four-beep tone is heard. The tone is heard only
once, but the message “NEWALRT” alternates with the talk group on the main display. Up to 8 received
messages can be stored. If a ninth message is received, the first (oldest) message is automatically deleted
to make room for the new message.
Received messages are displayed with the time and source information.
To display a Selective Alert Message:
1. Using the or button, scroll through the menu items until “Alerts Rcvd” appears. The oldest
message is displayed and scrolls across the top line of the display.
2. The message includes the time, the User ID, and alias of the sender along with the message.
3. To view the next message, press the or button to go forward or backwards.

1. Display the message.
2. Press the key and or to select Y or N.
3. At the “Delete? Y” prompt, press the key. The message will be deleted.
Received messages cannot be saved.
9.26 MAKING INTERCONNECT CALLS (P7370 ONLY)
1. Using the keypad, enter *9, followed by the telephone number being called, and the # key (no dashes
or spaces).
MM-013994-001, Rev. Ap1
87
*9<telephone number>#
Wait a couple of seconds and press and release the PTT button to initiate the call. An initial ring tone
will sound to indicate signal call initiation. Once the gateway picks up the call, the ring tone will
change. Press and hold the PTT and talk normally then release the PTT to listen.
2. To hang up the call, press the button or the key.
9.27 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.
Table 9-9: 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.
9.27.1 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.
MM-013994-001, Rev. Ap1
88
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.
9.27.2 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 “None,” only the emergency tone is heard, not the initial open mic transmission.
To dismiss or ignore the emergency, refer to Section 9.27.3.
9.27.3 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.
9.27.4 Clearing an Emergency Call or Alert
Check with your system administrator to ensure that your radio is configured with the
ability to clear an emergency.
MM-013994-001, Rev. Ap1
89
1. Press to declare an emergency. To clear an emergency, press and hold Option 2 button . While
holding , press the emergency button. Release both buttons when the “emergency cleared” tone
sounds.
2. The radio returns to your default selected talk group. The “EMERGENCY” display is removed from
the main screen.
If the radio is in stealth mode, clearing the emergency will cause the radio to exit stealth
mode.
9.28 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.
9.29 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].
9.30 V-TAC OPERATION
9.30.1 Extended Coverage Modes (“XCOV” and “XCOV-TG”)
In addition to all standard portable radio operating capabilities, Extended Coverage adds the V-TAC’s
bridging (vehicular repeat) functionality for accessing the OpenSky radio network. Each portable radio
connected to the V-TAC using Extended Coverage is considered a “client” on the V-TAC. Extended
Coverage benefits portable radio users since it allows them to get network connectivity using the
V-TAC’s higher transmit output power and better antenna system.
The V-TAC supports two Extended Coverage modes: Extended Coverage for individual users (display
reads “XCOV”) and Extended Coverage for a talk group (display reads “XCOV-TG”). Typically,
Extended Coverage is used after the vehicle’s operator has exited the vehicle with a portable radio unit
and the portable unit requires this bridging functionality to access the OpenSky radio network.
MM-013994-001, Rev. Ap1
90
The V-TAC takes advantage of OpenSky’s TDMA capability to eliminate interference between its local
and network radio links when operating in an Extended Coverage mode (XCOV or XCOV-TG), an
undesirable characteristic of many traditional vehicular repeater systems. Because the V-TAC employs
this technology, interference on the network and local radio links is minimized.
A V-TAC in XCOV or XCOV-TG mode sends its alias to clients. The alias is displayed in the second
line of the dwell menu of the client, (“VA <alias>”). The client must be connected to a V-TAC running
version OTP14.4 or for the V-TAC to provide the alias to the client. If the client is connected to a
V-TAC running version OTP14.3.1 or earlier, the client displays “VA None.”
9.30.2 Change Between Extended Coverage Modes
By default, the specific Extended Coverage mode utilized, either XCOV or XCOV-TG, is determined by
commands sent to the V-TAC and portable radios from the system administrator or radio installation
personnel. In other words, these commands determine which Extended Coverage mode the V-TAC and
radios normally use and determine the access method that must be employed by a portable radio to
connect to the V-TAC. After commands of this type are sent to the V-TAC and portable radios, each must
be rebooted (powered off and then back on) before the change takes effect.
A radio can manually override this command-determined default mode by entering *61# or *62# or by
using the Client Mode menu option. Command *61# sets the radio to use the XCOV mode and *62# sets
the radio to use the XCOV-TG mode. However, the connection will only be successful if the V-TAC
operating mode matches the manually selected portable V-TAC mode.
9.30.3 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.
9.30.3.1 Limitations Using Both XCOV and XCOV-TG
Portable radios connected to the V-TAC using either of the Extended Coverage Modes, XCOV or
XCOV-TG, will not channel-scan unless they lose radio frequency contact with the V-TAC. If manually
enabled, radios will not scan network channels.
9.30.3.2 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.
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 talk group, and scan mode. In
addition, the user cannot change talk group or profile.
9.30.4 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.
MM-013994-001, Rev. Ap1
91
9.30.4.1 Manually Accessing the XCOV Mode
P7370 Model Radios
1. Press *61# to manually access XCOV mode.
2. Press *60# to disconnect from XCOV mode.
All P7300 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.
9.30.5 Use XCOV-TG Mode
When using the XCOV-TG mode, up to thirty (30) client radios can connect to the V-TAC. However,
unlike XCOV, radios connected using XCOV-TG are limited to communicating only on the XCOV-TG
talk group and emergency communications. Advanced features such as selective calling and mobile data
operations are not available to the XCOV-TG connected clients.
The talk group used for XCOV-TG communications is the talk group that was selected at the V-TAC
when it entered XCOV-TG mode. Before a radio can connect to the V-TAC, the talk group must be
selected on the P7300. 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.
9.30.5.1 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#).
P7370 Model Radios
• Press *62# to manually access XCOV-TG mode.
• Press *60# to manually disconnect XCOV-TG mode.
All P7300 Model Radios
1. Press or until the Client Mode menu appears.
2. Press or until XCOV-TG is displayed.
3. Press to confirm mode selection. The radio reverts to the dwell display and the V-TAC icon is
displayed.
MM-013994-001, Rev. Ap1
92
9.30.6 Use Scene-of-Incident Mode
The Scene-of-Incident mode (SOI) is user-selectable. The SOI mode provides a local repeater function
(V-TAC) with no network connection.
CAUTION

10.1.1 Buttons and Knobs
This section describes the primary function of the button and knob controls. Refer to Figure 10-1 and
Figure 10-2.
POWER ON/OFF-VOLUME
CONTROL 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 40, which is the loudest level.
SYSTEM/GROUP/CHANNEL
CONTROL KNOB Selects pre-programmed channels. 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 System/Group/Channel control knob, loosen the set
screw on the System/Group/Channel control knob metal base (using a
1.27mm hex wrench), and remove the System/Group/Channel control
knob metal base. Replace the 16 channel ring with the channel stop
ring located at the desired channel. Re-install the
System/Group/Channel control knob metal base, tighten the set screw,
and re-install the System/Group/Channel control knob.
EMERGENCY/HOME BUTTON Automatically selects the pre-programmed Group/System by pressing
and holding for a programmed duration. It can also be used to declare
an emergency by pressing and holding for a programmed duration.
The button must be pre-programmed for either operation, but not both.

10.17 DIGITAL VOICE OPERATION
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system
and 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.
Groups or channels programmed for clear operation cannot transmit or receive digital
messages.
MM-013994-001, Rev. Ap1
109
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.
1. If receiving an analog message trunked call, the radio responds in the analog mode during the
hang time on the working channel.
2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time.
3. 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 auto-select, 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
auto-select 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 under different modes (clear and digital), only
the first occurrence of the group will be used.

11.1.1 Buttons and Knobs
This section describes the primary function of the button and knob controls. Refer to Figure 11-1 and
Figure 11-2.
POWER ON/OFF-VOLUME
CONTROL 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 40, which is the loudest level.
SYSTEM/GROUP/CHANNEL
CONTROL KNOB Selects systems or groups/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 System/Group/Channel control knob, loosen the set
screw on the System/Group/Channel control knob metal base (using a
1.27 mm hex wrench), and remove the System/Group/Channel control
knob metal base. Replace the 16 channel ring with the channel stop
ring located at the desired channel. Reinstall the
System/Group/Channel control knob metal base, tighten the set screw,
and reinstall the System/Group/Channel control knob.

11.16 DIGITAL VOICE OPERATION
Digital voice programmed systems have three (3) different voice modes: clear (analog), digital, and
private (encrypted). The voice modes are programmed on a per-group basis within each trunked system
and on a per-channel basis within each conventional system.
11.16.1 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.
MM-013994-001, Rev. Ap1
128
Groups or channels programmed for clear operation cannot transmit or receive digital or
private messages.
11.16.2 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
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.
1. If receiving an analog message trunked call, the radio responds in the analog mode during the hang
time on the working channel.
2. If receiving an analog I-Call, the radio responds in the analog mode during the hang time.
3. 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.
11.16.3 Private Mode
The Private Mode allows the radio to transmit encrypted messages and receive clear or private
transmissions. The radio transmits private if the group is programmed for private operation and forced
operation is pre-programmed. If auto-select operation is pre-programmed and the radio is in the Private
Mode, the radio transmits in the mode of the received call if the hang time is active. If no hang time is
active, the radio transmits private.
Cryptographic keys are transferred to the radio using a cryptographic Keyloader. Up to seven (7)
different cryptographic keys, numbered 1-7, can be transferred from a Keyloader and stored in the radio.
An individual key is automatically selected on a per-group basis according to the radio programming.
Groups and channels within the digital system can be programmed for keys 1-7 (private). Up to 8 banks
of 7 keys can be stored for private systems. The bank is specified per system.
When operating on a group programmed for Private Mode, all transmissions are private transmissions and
the radio receives clear and private signals. The status icon is displayed when the Private Mode is
enabled. If the selected group is programmed for auto-select capability, the mode may be toggled
between private and clear with the key, then following the selection mode rules. Radios programmed
for forced private operation do not allow a change of the transmit mode.
11.16.3.1 Displaying the Currently Used Cryptographic Key Number
To display the currently used Cryptographic Key Number for either the system encryption key (for
special call such as individual, phone, all, agency or fleet) or the group key (for group calls), perform the
following procedure:
1. Press the button.
2. Use the or button to select "DISP KEY."
MM-013994-001, Rev. Ap1
129
3. Use the or button to toggle between displaying the system key (Figure 11-11) or the
group/channel key (Figure 11-12).
Figure 11-11: System Encryption Key Display
Figure 11-12: Group/Channel Encryption Key Display
11.16.3.2 Key Zero
All cryptographic keys can be zeroed (erased from radio memory) by pressing the button and while still
pressing this button, press and hold the OPTION button. Press both buttons for 2 seconds. A series of
beeps will begin at the start of the 2 second period and then switch to a solid tone after the keys have been
zeroed. The display will indicate KEY ZERO.
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Keyloader into the
radio before private communications may continue.
11.16.4 Private Operation
11.16.4.1 Receiving an Encrypted Call
When receiving, the radio automatically switches between clear or private operation. If the transmission
being received is an encrypted transmission, it will be decrypted, the icon is displayed, the receiver will
unsquelch and the message will be heard in the speaker. For this to occur, the selected group or channel
must be programmed for private operation and the correct cryptographic key must be loaded into the
radio.
11.16.4.2 Transmitting an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in Private Mode by pressing key; then follow the selection mode rules. On a
System radio, the key can be used to toggle the Private Mode ON/OFF. When Private Mode is
enabled, the icon is displayed.
3. If the last state of the radio was Private Mode, the Private Mode will be enabled on power up. Also,
the Private Mode will be enabled if forced operation has been programmed in the radio.
If a group is not programmed for Private Mode operation, PVT DIS will be displayed if an attempt is
made to enable private transmit mode. It is not possible to operate on this group in Private Mode.
If the radio does not have the correct encryption key loaded, NO KEY# will be displayed and the call
will not be transmitted.
MM-013994-001, Rev. Ap1
130
4. Continue with standard transmission procedures. A Private Mode access tone will be heard when the
PTT button is pressed.
11.16.4.3 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 auto-select, 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 private and entered in the scan list, it can receive clear and private calls, provided
auto-select 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, digital, or
private), only the first occurrence of the group will be used.

• 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.
MM-013994-001, Rev. Ap1
131
• 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).
11.17.2 Adding Groups to a Scan List

OFF and then powered ON.
11.18 SCANNING TRUNKED SYSTEMS
The radio can be programmed with the following System Scan features. These features are automatically
enabled when the radio is powered ON. A key or menu option is also defined to allow the System Scan
MM-013994-001, Rev. Ap1
133
features to be toggled during radio operation. The System Scan state will be maintained through system
changes but will default to ON when the radio is powered ON.
Enable/Disable via Menu Selection
Press and then use the or buttons to scroll through the selections until SYS SCAN is
displayed. Then press to toggle the System Scan state. The SYSC ON or SYSC OFF display
message is displayed for two seconds to show the new state.
Enable/Disable via Pre-Programmed Keypad Key
Press the key pre-programmed to toggle System Scan and the SYSC ON or SYSC OFF display message
is displayed for two seconds to show the new state.
11.18.1 Wide Area System Scanning
The P7300 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.
11.18.2 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.
11.18.2.1 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.
11.18.2.2 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 8.20.3 for more information on ProScan.
11.18.3 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
MM-013994-001, Rev. Ap1
134
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.
11.19 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.
11.19.1 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.
11.19.2 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 8-4) and is ready for voice transmission. *TXEMER* flashes on line two in
the display until the emergency is cleared.
3. Press PTT and speak into the microphone in a normal voice. and momentarily turn ON.
4. Release PTT when the transmission is complete.
To clear the emergency first press and hold the button. While continuing to hold the button, press the
EMERGENCY button. (This will work if the radio is programmed to clear emergencies.)
11.20 INDIVIDUAL CALLS
11.20.1 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.
MM-013994-001, Rev. Ap1
135
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.

11.21.3 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.
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.

MM-013994-001, Rev. Ap1
141
(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.
11.25 PORTABLE DATA
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 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).
11.25.1 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.
