RF ENERGY EXPOSURE INFORMATION
2.1
RF ENERGY EXPOSURE AWARENESS, CONTROL INFORMATION,
AND OPERATION INSTRUCTIONS FOR FCC OCCUPATIONAL USE
REQUIREMENTS
Before using your mobile two-way radio, read this important RF energy awareness and control
information and operational instructions to ensure compliance with the FCC’s RF exposure
guidelines.
This radio is intended for use in occupational/controlled conditions, where users have full
knowledge of their exposure and can exercise control over their exposure to meet FCC
limits. This radio device is NOT authorized for general population, consumer, or any
other use.
Changes or modifications not expressly approved by Harris Corporation could void the
user's authority to operate the equipment.
CAUTION
This two-way radio uses electromagnetic energy in the radio frequency (RF) spectrum to provide
communications between two or more users over a distance. It uses RF energy or radio waves to send and
receive calls. RF energy is one form of electromagnetic energy. Other forms include, but are not limited
to, electric power, sunlight, and x-rays. RF energy, however, should not be confused with these other
forms of electromagnetic energy, which, when used improperly, can cause biological damage. Very high
levels of x-rays, for example, can damage tissues and genetic material.
Experts in science, engineering, medicine, health, and industry work with organizations to develop
standards for exposure to RF energy. These standards provide recommended levels of RF exposure for
both workers and the general public. These recommended RF exposure levels include substantial margins
of protection. All two-way radios marketed in North America are designed, manufactured, and tested to
ensure they meet government established RF exposure levels. In addition, manufacturers also recommend
specific operating instructions to users of two-way radios. These instructions are important because they
inform users about RF energy exposure and provide simple procedures on how to control it. Please refer
to the following websites for more information on what RF energy exposure is and how to control your
exposure to assure compliance with established RF exposure limits.
http://www.fcc.gov/oet/rfsafety/rf-faqs.html
http://www.osha.gov./SLTC/radiofrequencyradiation/index.html
2.1.1
Federal Communications Commission Regulations
Your Harris Corporation M7300 mobile two-way radio is designed and tested to comply with the FCC RF
energy exposure limits for mobile two-way radios before it can be marketed in the United States. When
two-way radios are used as a consequence of employment, the FCC requires users to be fully aware of
and able to control their exposure to meet occupational requirements. Exposure awareness can be
facilitated by the use of a label directing users to specific user awareness information. Your Harris
Corporation M7300 two-way radio has an RF exposure product label. Also, your M7300 Installation and
Operator’s Manuals include information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.

OPERATION SAFETY RECOMMENDATIONS
3.1
TRANSMITTER HAZARDS
The operator of any mobile radio should be aware of certain hazards common to
the operation of vehicular radio transmitters. A list of several possible hazards is
given:

Explosive Atmospheres – Just as it is dangerous to fuel a vehicle with the motor running, similar
hazards exist when operating a mobile radio. Be sure to turn the radio off while fueling a vehicle. Do
not carry containers of fuel in the trunk of a vehicle if the radio is mounted in the trunk.
Areas with potentially explosive atmosphere are often, but not always, clearly marked. Turn OFF
your radio when in any area with a potentially explosive atmosphere. It is rare, but not impossible that
the radio or its accessories could generate sparks.

Interference to Vehicular Electronics Systems – Electronic fuel injection systems, electronic antiskid braking systems, electronic cruise control systems, etc., are typical electronic systems that can
malfunction due to the lack of protection from radio frequency energy present when transmitting. If
the vehicle contains such equipment, consult the dealer and enlist their aid in determining the
expected performance of electronic circuits when the radio is transmitting.

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)

Liquefied Petroleum (LP) Gas Powered Vehicles – Mobile radio installations in vehicles powered
by liquefied petroleum gas with the LP gas container in the trunk or other sealed-off space within the
interior of the vehicle must conform to the National Fire Protection Association standard NFPA 58
requiring:
 The LP gas container and its fittings.
 Outside filling connections shall be used for the LP gas container.
 The LP gas container shall be vented to the outside of the vehicle.
3.2
SAFE DRIVING RECOMMENDATIONS
(Recommended by AAA)
16

Read the literature on the safe operation of the radio.

Keep both hands on the steering wheel and the microphone in its hanger whenever the vehicle is in
motion.

Place calls only when the vehicle is stopped.

When talking from a moving vehicle is unavoidable, drive in the slower lane. Keep conversations
brief.

If a conversation requires taking notes or complex thought, stop the vehicle in a safe place and
continue the call.

Whenever using a mobile radio, exercise caution.
MM-014716-001, Rev. E
OPERATING RULES AND REGULATIONS
Two-way FM radio systems must be operated in accordance with the rules and regulations of the local,
regional, or national government.
In the United States, the M7300 mobile radio must be operated in accordance with the rules and
regulations of the Federal Communications Commission (FCC). As an operator of two-way radio
equipment, you must be thoroughly familiar with the rules that apply to your particular type of radio
operation. Following these rules helps eliminate confusion, assures the most efficient use of the existing
radio channels, and results in a smoothly functioning radio network.
When using your two-way radio, remember these rules:

It is a violation of FCC rules to interrupt any distress or emergency message. As your radio operates
in much the same way as a telephone “party line,” always listen to make sure that the channel is clear
before transmitting. Emergency calls have priority over all other messages. If someone is sending an
emergency message – such as reporting a fire or asking for help in an accident – KEEP OFF THE
AIR!

The use of profane or obscene language is prohibited by Federal law.

It is against the law to send false call letters or false distress or emergency messages. The FCC
requires that you keep conversations brief and confine them to business. To save time, use coded
messages whenever possible.

Using your radio to send personal messages (except in an emergency) is a violation of FCC rules.
You may send only those messages that are essential for the operation of your business.

It is against Federal law to repeat or otherwise make known anything you overhear on your radio.
Conversations between others sharing your channel must be regarded as confidential.

The FCC requires that you identify yourself at certain specific times by means of your call letters.
Refer to the rules that apply to your particular type of operation for the proper procedure.

No changes or adjustments shall be made to the equipment except by an authorized or certified
electronics technician.
Under U.S. law, operation of an unlicensed radio transmitter within the jurisdiction of
the United States may be punishable by a fine of up to $10,000, imprisonment for up to
two (2) years, or both.
4.1
OPERATING TIPS
The following conditions tend to reduce the effective range of two-way radios and should be avoided
whenever possible:

Operating the radio in areas of low terrain, or while under power lines or bridges.

Obstructions such as mountains and buildings.

In areas where transmission or reception is poor, some improvement can be obtained by moving a few
yards in another direction or moving to a higher elevation.

MM-014716-001, Rev. E
PRODUCT DESCRIPTION
The M7300 mobile is a state-of-the-art radio designed to meet the critical demands of its users. The
M7300 mobile supports multiple operating modes, including OpenSky® digital trunked operation
(700/800 MHz radios only), Enhanced Digital Access Communications System (EDACS®) or ProVoiceTM
trunked modes, P25 digital trunked mode, P25 digital conventional mode, and conventional analog mode.
The M7300 also provides Project 25 conventional capabilities for interoperability with other users in the
700/800 MHz bands.
The optional Global Positioning System (GPS) receiver module can provide standard GPS formatted data
over the air for vehicle tracking systems.
The optional Advanced Encryption Standard (AES) is available for maximum communications security.
OpenSky radios benefit from a flexible, software-based digital radio design. Features and user profiles are
software-defined and can be reprogrammed over the air. The optional over-the-air programming feature
allows communications protocols to be changed easily and added at any time.
The M7300 radio uses the CH-721 Control Head which is available in two models: System and Scan. The
display is designed to maximize readability and ease of use. The CH-721 utilizes a 3-line 12-character
alphanumeric display with large buttons, volume knob, and channel knob, providing a user-friendly
interface.
5.1
CH721 CONTROL HEADS
The CH721 control head is available as either a Scan or System model and can be mounted with the radio
(Front Mount) or it can be mounted and operated remotely.
The following lists available control head options.

CU23218-0001 – Local Scan

CU23218-0002 – Remote Scan

CU23218-0003 – Local System

CU23218-0004 – Remote System
For remote mount installations configured with a CH721 control head, all normal radio operations and
interfaces can be handled via the control head connected to the radio unit via a 3-wire Controller Area
Network (CAN) cable. Up to five control heads may be attached to a trunk mount radio and up to four
control heads can be connected to a front-mount M7300. Each control head provides a serial access point
for data and any one (only one at a time) can be connected to a data device such as a personal computer.
Where multiple control heads are connected or where a dash-mount radio is installed with additional
remote control heads, the following features are available from each position:
18

Outgoing voice calls can be initiated. (Any control head can initiate a call but only one can talk at a
time. All other connected control heads hear both sides of the conversation.)

Incoming and outgoing audio can be heard. (Outgoing audio is not broadcast at the source position.)

Independent audio control is available.

Radio settings such as talk group, scan mode etc., can be controlled. (Any connected control head can
override the radio settings of other connected control heads.)

Comfort settings, such as volume and display brightness that are applicable to the individual control
head can be adjusted and cannot be overridden by other control heads.
MM-014716-001, Rev. E

5.2
An optional intercom function is available between control units. Audio is broadcast to ALL
connected control heads.
INTERCOM OPERATION
The intercom option, a licensed option, allows the M7300 radio to pass audio locally between control
heads and not over the network. It gives users at multiple control heads connected to the same radio the
ability communicate with each other without transmitting over-the-air. When activated, incoming network
radio calls are still scanned and broadcast at each control head.
5.3
GPS RECEIVER
An optional Global Positioning System (GPS) tracking receiver is available for M7300 radios. It provides
vehicle location information to dispatch personnel via the OpenSky digital data radio network.

OPENSKY OPERATION (700/800 MHZ RADIOS ONLY)
CH721 FRONT PANEL COMPONENTS
The front panel of the control head includes a dot matrix display, controls for menu navigation, an
emergency button, three pre-set buttons, a Power On-Off/Volume Control knob, and a microphone
connector. In addition, the system model control head features a DTMF keypad (Figure 7-1). Table 7-1
lists all default front panel controls and their functions.
Figure 7-1: System Model
Figure 7-2: Scan Model
The buttons on the front panel are backlit for operation in a low ambient light level such as nighttime
operation. Some buttons also flash to provide feedback of various operating conditions.
In addition, the front panel contains a light-level sensor that samples ambient light levels for automatic
display and button backlight brightness adjustments. In other words, it automatically brightens the display
and backlights when higher external light levels exist and it automatically dims the display and backlights
during lower external light levels.

POWER UP AND VOLUME CONTROL
7.2.1
Power Up
1. Rotate the Power On-Off/Volume Control knob clockwise to power on the radio. The display
illuminates when the radio powers up.
2. Wait for the power-up sequence to complete, which takes approximately ten (10) seconds.
During this time, if enabled for auto registration, the radio is provisioned with a customized user
personality designed for the user’s specific needs by the OpenSky network administrator.
If this personality contains encrypted talk groups or if the user is authorized for, and intends to use,
manual encryption, User Login is required. This requires a system model control head so that the
User ID and password can be entered.
3. When provisioning is complete, the radio displays the Dwell Display.
If User Login is required, the bottom line of the Dwell Display flashes the message “Pls Login.”
7.2.2
Volume Control
Turn the Power On-Off/Volume Control knob clockwise to increase the volume and counter-clockwise to
decrease the volume.
7.3
SELF-TEST
After power-up, the M7300 radio undergoes a multi-function automatic registration procedure. As many
as sixteen (16) possible radio profiles are downloaded to the radio from the network in response to the
User’s ID.
7.4
LOGIN TO THE NETWORK
Login occurs either automatically (auto registration) if the radio has a valid registration or, if enabled and
authorized for encryption (Section 7.31), requires the user to enter a User ID and password.
If encryption is enabled and authorized on the radio, the user is prompted to “Pls Login” with the *1 login
command, a User ID, and password [System Model Control Head required].
1. Press *1 (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 # between the consecutive duplicate numbers
so the radio does not interpret the entry as a letter (“D” in this example).

If the radio is configured for numeric-only passwords, do not enter # between duplicated
numbers.
5. Press the # key twice.
23
MM-014716-001, Rev. E
The User ID may be remembered from the previous log-in. (Refer to Section 7.5 for further details
regarding log-off commands.) The password is established before the radio is put into operation. Contact
the local OpenSky network administrator for more information.
If necessary, contact radio system administration personnel for log-in assistance and/or
radio-specific log-in instructions.
7.5
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. Manually log-off by pressing *0## (requires System Model).
7.6
TURN THE RADIO OFF
To turn the radio off, rotate the Power On-Off/Volume Control knob counter-clockwise. In multiple
control head installations, turning off the last powered-up control head also turns off the radio.
Several user-selected radio settings (i.e., scan mode, pre-set buttons, and side tone levels) are maintained
for the next operational session. At the next radio power-up, maintained settings restore, along with the
network personality settings. In multiple control head installations, settings are maintained for each
control head position.
If power is abruptly disconnected from the radio prior to executing the correct turn-off
procedure, user-selected radio settings and last-tuned channel information is lost. This
can extend the time required for the radio to register with the network upon the
subsequent power-up.
7.7
MENU DISPLAY AND CONTROL AREA
Following power-up, the radio display shows the default talk group (Figure 7-3).
, CLEAR or
OPTION changes the display to the next available menu. In many cases, the dwell display automatically
re-appears after no menu buttons are pressed for a short period of time (between 10 and 30 seconds). For
some menus such as the GPS and User ID menus, this does not occur until the user presses a front panel
button.
When the dwell display is active, it changes dynamically to reflect the current profile, received talk
group/caller ID (when available), or channel (when enabled).
The radio’s display is highly interactive. It responds in the top and bottom text lines as the user presses
the menu buttons to scroll through the menu loop and the entries for each menu. Table 7-4 outlines the
basic menu structure (refer to Section 7.13).

PERSONALITY
As illustrated in Figure 7-4, 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 and at user log-in. Each personality can contain up
to sixteen (16) profiles and each profile can contain up to sixteen talk groups.
7.11.1 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.

7.11.2 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.

3. A brief message is displayed on the 2nd line of the display (Kypd Lck, Kypd Unlck).
7.14.4 Password Entry
Password entry requires a system model control head. Password characters are encrypted on the display
using symbols to indicate the entry. The encryption symbols for each entry appear in the display as they
are scrolled through, for example: '-' and '+'. Press the # key twice to complete the entry process.
If the password is wrong, the radio does not successfully register with the network for
wide area voice reception. The radio can still be used in single-site mode.
7.14.5 Dual-Tone Multi-Frequency
Dual-Tone Multi-Frequency (DTMF) is the system used by touch-tone telephones. DTMF assigns a
specific tone frequency to each key so a microprocessor can easily identify its activation. The radio
supports DTMF with a system model control head (Figure 7-1). This allows for specific tasks such as
entering a user ID and password, or selective calling.
When a key on the DTMF keypad is pressed, the DTMF tone is played through the radio’s speaker.
7.14.6 DTMF Overdial
Using the keypad on a System Model, the radio can transmit DTMF tones corresponding to
numbers/characters 0 — 9, * and # on the keypad. To overdial numbers/characters, transmit by pressing
and holding the PTT button and then, press the corresponding keys (one at a time) on the keypad.
7.15

STEALTH MODE
For some users, it is important to be able to turn off the radio’s display lights, button backlighting, volume
and side tones, but not the radio traffic. For example, in covert operations, lights and sounds could
inadvertently expose an otherwise unobservable radio user. For this purpose, the radio has a Stealth
feature that disables the radio display light, indicator light and audible side tones.
When stealth mode is on, the radio continues to scan the programmed list of talk groups and the user can
key-up on the selected talk group.

7.20
ADJUST 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.
To temporarily disable the side tones that could expose the user’s presence and position, use the menu
buttons to access the “Side Menu” and select “Off” from the menu choices.
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 to set side tone level:
1. Scroll through the menu until the “Side Menu” appears in the bottom line of the display.

7.22
RECEIVE AND TRANSMIT VOICE CALLS
As soon as the radio completes the startup/log-on/provision/self-test sequence and registers on the
OpenSky network, voice calls from talk groups in the active profile is audible.
35
MM-014716-001, Rev. E
7.22.1 Receive a Voice Call
The Alias/User ID/Talk Group name is only displayed if that dwell display option is
selected using the MENU button. For example, if the user sets the dwell display option to
profile, the profile continues to be displayed when a call is received.
No action is required to receive a voice call. The display responds to incoming voice calls as follows:

When the dwell display is set to received talk group and the scan mode is Normal or Fixed:
a. If the received talk group matches the selected talk group, then the alias (if available) or user id of
the incoming caller is displayed.
b. If the received talk group does not match the selected talk group, then the received talk group
name is displayed

When the dwell display is set to received talk group and the scan mode is None, the radio only
receives voice on its selected talk group. When the call is received, the alias (if available) or the user
ID of the incoming caller is displayed.

When the dwell display is not set to received talk group, then there is no display indication of an
incoming call.
A radio receiving a System All Call displays “All Call” instead of the alias. A radio not
transmitting on a talk group in emergency status drops all other calls to scan into an All
Call.
Refer to Section 7.26 for detailed information on talk group scanning. Refer to Section 7.31 for detailed
information regarding sending and receiving encrypted calls.
7.22.2 Transmit a Voice Call
Transmit a voice call as follows:
1. Turn the radio on.
2. If required, log-in to the network using a user ID and password (see Section 7.4).
3. Select the desired talk group for transmitting on.
4. Press and hold the Push-to-Talk (PTT) button on the hand-held microphone, pause for a moment,
and then speak normally. For maximum clarity, hold the microphone approximately 1 ½ inches from
the mouth and do not shout or whisper into it. If the call is queued by the network, wait for the grant
tone to sound before speaking.
5. Release the PTT button when finished speaking.
Refer to Section 7.31 for detailed information regarding sending and receiving encrypted calls.
7.23
ADJUST AUDIO TREBLE LEVEL
The tone of received signals can be adjusted using the radio’s “Treble Menu” as follows:
1. Scroll through the menu until “Treble Menu” appears. The radio’s current treble level setting
indicates in the top line of the display. There are four levels available: low, medium, medium-high,
and high.

MM-014716-001, Rev. E
2. Use
to increase or decrease.
3. Press the MENU button or wait a few seconds to return to the Dwell Display.
7.24
INTERCOM MODE
The optional intercom mode gives users at multiple control heads connected to the same radio the ability
to communicate with each other without transmitting over-the-air. Turn intercom mode on and off using
the “INTERCOM” menu as follows:
1. Scroll through the available menu items until “INTERCOM” appears in the display.
2. Use
to toggle between “On” and “Off.”
When intercom mode is turned on:

Incoming voice calls override intercom communications for the duration of the voice call. The radio
and associated control heads remain in intercom mode and intercom communications resume when
the voice call ends.

“TG: INTERCOM” appears in the control head’s display when talking on the intercom. This indicates
microphone audio is not sent out on the selected talk group; rather, it remains localized between the
radio control positions (i.e., the control heads connected to the mobile radio).

If a call exists on the currently selected talk group when a PTT button is pressed at one of the control
heads, “TG: in use” appears in the display to indicate intercom mic audio cannot preempt the call on
the talk group.
CAUTION
7.25
A user at a radio with only one control head/front panel can turn intercom mode on. In
this case, pressing the microphone’s PTT button does not send microphone audio
anywhere.
TALK GROUP LOCK OUT
There are two ways of focusing voice communications by suppressing calls from talk groups in the
currently active profile:
1. No Scan. By turning scan off (selecting “No Scan” via the “ScnModeMenu”), only the selected talk
group is audible.
2. Lock Out. By locking out selected talk groups, the “chatter” of the locked-out talk groups cannot be
heard. This focuses the user’s scanning resources to calls only on desired talk groups.
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.
Lock out is a listening (receive) function and only blocks received calls on locked out
talk groups. Lock out does not affect transmit capability. The above methods 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.
37
MM-014716-001, Rev. E
P1 and P2 talk groups cannot be locked out.
The default emergency and emergency-capable talk groups can be locked out if they are NOT in an
emergency state. If a talk group is locked out and is subsequently changed to the currently selected talk
group, it is automatically 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.
7.25.1 Lock Out a Talk Group
1. Scroll through the menu until “LockOutMenu” appears in the bottom line of the display. The name of
a talk group in the currently active profile appears in the top line.
2. Use
to scroll through the list of talk groups, if any, until the desired talk group for lock out
appears in the top line of the display.
3. Press the MENU button to lockout the displayed talk group. A less than symbol (<) appears next to
the talk group’s name.
4. Repeat steps 2 and 3, as needed, to lockout additional talk groups.
The dwell display re-appears a few seconds after button presses end.
While scrolling through talk groups in the active profile, the only talk groups that appear in the
“LockOutMenu” are those in the active profile.
7.25.2 Unlock a Talk Group
1. Scroll through the menu until “LockOutMenu” appears in the bottom line of the display. The name of
a talk group in the currently active profile appears in the top line.
2. Use

MAKE SELECTIVE CALLS
Selective calling is a feature that allows two radio units to obtain and utilize an independent voice path for
a private call. Radios can be configured to both initiate and receive selective calls or to only receive
selective calls.
In the OpenSky system, a source radio can be configured to initiate selective calls through a preprogrammed list in memory. This method uses the “speed dial list” set up by the OpenSky network
administrator and provisioned as part of the registration process.
In addition, a properly equipped source radio can initiate a selective call to any radio in the system by
entering the ten-digit voice user ID (which looks like a telephone number) of the target device. Entering a
selective call number without using the speed dial feature requires a system model control head (Figure
7-1). See Section 7.14.5 for more detail.
Selective calls are terminated if an emergency is declared. The network limits selective
calls to ten (10) minutes maximum.
Table 7-8 lists and defines the messages that may be displayed by the radio during a selective call.

SELECTIVE ALERT
Selective alert messaging is an OTP feature allowing one of up to eight (8) pre-programmed text
messages (refer to Section 7.28.3) to be sent from one radio to another. The user specifies a destination
radio’s User ID, selects one of the pre-programmed text messages, and then transmits it to the destination
radio. The message delivery system adds 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. Refer to Table 7-9 for a list of possible status messages.
The first few characters of a message are part of the message text entered when the message is
programmed. This programming is performed by the system or network administration personnel.
Messages successfully received by the destination radio are stored until deleted or until the radio is power
cycled.

7.30
to reject an incoming Interconnect Call.
EMERGENCY COMMUNICATIONS
The M7300 mobile radio can transmit both emergency voice calls and emergency alerts over the entire
network. OpenSky handles emergency calls and alerts with the highest priority.
For critical voice communications, an emergency call can be raised on the default talk group or the
currently selected talk group by “declaring” an emergency on the talk group. The exact talk group is
determined by the currently active profile. After successfully declaring an emergency on a talk group, the
declaring radio’s microphone remains “hot” for a predetermined amount of time. In other words, the radio
transmits audio for a period of time even when the microphone’s PTT button is not pressed. An
emergency talk group is provided greater priority and infinite hang-time by the radio system’s
infrastructure. Hang-time is the maximum duration of quiet time between transmissions on the talk group
before the infrastructure assets are automatically taken away. Because an emergency call is handled on a
talk group, it is received by all radios and consoles monitoring the talk group.
An emergency alert is a data message sent by the radio to the MIS console (or any console capable of
receiving it). It identifies the radio declaring the emergency, and the radio’s location (if the radio is
equipped with a GPS receiver). Voice audio is not automatically transmitted during the emergency if the
administrator configures the radio for alert notification only.
7.30.1 Declare an Emergency Call or Alert
To declare an emergency call or emergency alert, press and release the orange Emergency button. This
button is located just to the right of the 5-button Menu and Select keypad; see Figure 7-1 on page 21. The
emergency is raised after the Emergency Raise Delay (default is one second).

The OpenSky network administrator determines if the Emergency button is used to declare an
emergency call or if it is used to declare an emergency alert. This is based upon the radio’s currently
active profile.

The OpenSky network administrator also determines if the emergency is declared on the currently
selected talk group or a “default” emergency talk group. Again, this is based upon the radio’s
currently active profile. A talk group upon which an emergency is declared on is considered an
“emergency talk group.”

Upon successful emergency declaration:

44
An emergency tone sounds in the radio’s speaker/headset if the radio is not in stealth mode.
MM-014716-001, Rev. E

At the declaring radio, the Emergency button flashes red if the radio is not in stealth mode. The
administrator can configure the radio to automatically transmit upon successful emergency
declaration, at which point the MENU button flashes red. However, the MENU button flashing
red is not a requirement for successful emergency declaration.

On the declaring radio during an emergency call declaration, the talk group that the emergency is
declared on is temporarily displayed and then the word “EMERGENCY” flashes on the second
line of the display.

For an emergency alert declaration, “EMERG ALERT” appears in the bottom line of the display.

For an emergency call declaration, other radio users and/or dispatchers at consoles hear the
emergency signal, a distinctive 3-tone burst. They also hear audio from the declaring radio’s
“hot” microphone, if any.

For an emergency alert declaration, only dispatchers at consoles hear the emergency signal and, if
any, audio from the declaring radio’s “hot” microphone.

For an emergency call, the declaring radio’s microphone remains “hot” for a predetermined
amount of time. In other words, the radio transmits audio for a period of time even when the
microphone’s PTT button is not pressed. Audio is transmitted over the emergency talk group.
When the microphone is “hot” for this initial period (typically ten seconds), simply speak into it
for voice transmission.
If an emergency declaration is not successful, the radio periodically re-attempts until it is successful.
During this retry period, the radio flashes “EMERG PEND” on the bottom line of the display. It displays
“EMERG RETRY” for each attempt.
7.30.2 Silent Emergency
When this feature is enabled and an emergency call or alert is declared by pressing the emergency button,
the radio does not play a tone and displays an abbreviated emergency message (default is EBA). This
feature is enabled or disabled via programming or via the menu.
If the Silent Emergency feature is enabled or disabled via programming, the setting survives
power cycle. Enable/Disable selection via the menu does NOT survive power cycle and the
enable/disable state reverts to the programmed setting at power up.
7.30.3 Clear an Emergency Call or Alert
Check with the system administrator to ensure that the radio is programmed to allow an
emergency to be cleared.
If enabled via programming, clear an emergency by:
1. Pressing and holding the CLR/CLEAR button and simultaneously pressing the emergency button.
2. After the Emergency Cleared Tone sounds, release both buttons.
If the radio is in stealth mode, clearing the emergency takes the radio out of stealth mode.
45
MM-014716-001, Rev. E
7.30.4 Receive an Emergency Call
Upon receiving an emergency call declared by another radio:

An emergency tone sounds in the radio’s speaker/headset (three short high-pitched beeps).

“EMERGENCY” flashes in the display if the radio is not in stealth mode. When receiving voice in an
active emergency, the flashing “EMERGENCY” is inhibited so that the alias of the sender can be
seen.

On receiving radios with the emergency talk group selected, the alias of the sending party is displayed
for 5 seconds during the open-mic period, then the word “Emergency” flashes on the second line of
the display and continues until the emergency state ends.

If scan mode is set to “No Scan” and the emergency was declared on the selected talk group, audio on
the emergency talk group is heard in the speaker/headset. See page 38 for additional information on
“No Scan” operation.

If scan mode is set to “No Scan” and the emergency was declared on a talk group other than the
selected talk group, the emergency talk group (identified by an “*”) must be selected before audio on
it is heard in the speaker/headset.

If scan mode is set to “Normal” and the emergency was declared on the selected talk group, the
selected/emergency talk group’s name remains in the top line of the display. Audio on the emergency
talk group is heard in the speaker/headset.

If scan mode is set to “Normal” and the emergency was declared on a talk group other than the
selected talk group, the emergency talk group’s name appears in the bottom line of the display. Audio
on the emergency talk group is heard in the speaker/headset.

The declaring radio's alias appears in the bottom line of the display when the emergency talk group is
selected.

An emergency call can be dismissed as described in the following section.
A radio declaring an emergency on a talk group has a “hot” mic time period of typically
ten (10) seconds just after it declares the emergency. This time period may be adjusted
by system or network administration personnel on a per radio basis.
7.30.5 Dismiss an Emergency Call
An emergency is dismissed for a configurable amount of time only (default = 5 minutes).
To ignore an emergency call declared by another radio user:
1. Press
until “EmgDismiss” appears in the display.
2. Press
until the talk group in the emergency state appears, as indicated by an asterisk (*)
following the talk group’s name.
3. Press the MENU button.
46
MM-014716-001, Rev. E
The emergency dismiss timer is cleared when the emergency is cleared.
7.31
ENCRYPTION
In the OpenSky network, both data and voice use a 128-bit or 256-bit key encryption standard published
by the Federal Information Processing Service (FIPS), called Advanced Encryption Standard (AES). AES
is approved by the U.S. Department of Commerce for encryption of classified materials.
When encryption is enabled on the network, data is encrypted from the MDIS to the Mobile End System
(MES) (e.g., M7300 mobile radio). This form of encryption provides air-link security.
Voice encryption is handled either automatically or manually. Automatic encryption is initiated through
the Unified Administration Server (UAS) for a specific talk group and requires nothing from the user.
Manual encryption is initiated by two or more radio users and requires system model control heads. Both
methods of encryption are discussed in the following sections.
7.31.1 Automatic Encryption
For automatic encryption, a network administrator selects the talk group to be encrypted at the interface to
the UAS. Once the talk groups have been selected and identified as secure, credentials for key generation
are generated automatically by the system and provisioned to authorized users. This process requires that
authorized users login to the network and be authenticated. Encryption keys require no manual handling
and are never sent “in the clear” over any network interface or air-link.
1. “Pls Login” appears displayed in the bottom line of the dwell display.
2. Login normally using the keypad on a system model control head to enter User ID and Password.
If a user is engaged in a call on a talk group encrypted at the network administrator level, “Secure Call”
appears in the bottom line of the dwell display if the user is logged into that talk group.
If a secure call is in progress elsewhere and the user has not logged in, the bottom of the dwell display
alternates between “No Access” and the alias of the radio that is currently engaged in the secure call.
7.31.2 Manual Encryption (System Model)
Two or more users can manually encrypt a call, if enabled, without an established encrypted talk group. A
pre-determined key is required at each radio.
The key must be pre-determined by the users prior to making a manually encrypted call
on a talk group and is entered into the radio using the keypad. For 128 bit encryption, this
key is between 1 and 16 digits. For 256 bit encryption, this key is between 17 and 32
digits.
If two communicating radios have different (manually-defined) keys, receive audio at
each radio sounds garbled.
With manual encryption enabled, unencrypted radio users on the talk group can still make standard voice
(unencrypted) calls on the talk group. However, if an unencrypted user attempts to transmit on the talk
group when one of the encrypted users is already transmitting on the talk group, the unencrypted radio
sounds a deny tone and “No Access” appears in the display. Also, the encrypted user can hear standard
unencrypted calls, but cannot respond while still manually encrypted.
47
MM-014716-001, Rev. E
Do not set a talk group for manual encryption if it has been set for encryption by the
network administration personnel.
CAUTION
Perform the following to transmit or receive manually encrypted calls:
1. Press *32 on the keypad.
2. Enter the key (1 – 16 digits for 128 bit encryption; 17 – 32 digits for 256 bit encryption).
3. Press the # key.
4. To end manual encryption, press *33#.
If a user is engaged in a call on a talk group that has been manually encrypted at the radio level, the user
sees “Secure Call” on the bottom of the dwell display.
If a secure (encrypted) call is in progress, and the user has not entered the key, the bottom of the dwell
display alternates between “No Access” and the alias of the radio that is currently engaged in the secure
call.
Once the user has terminated manual encryption, “UnSecure” appears temporarily in the bottom line of
the dwell display.
7.32
PRESET BUTTONS
The front panel contains three buttons labeled A, B, and C. By holding one of these buttons down for
approximately three (3) seconds, the following current information is saved to the function of that button:

Selected talk group

Selected profile

Selected priority talk group

Lockouts

Scan mode

Intercom mode
Presets are saved and restored to/from non-volatile memory. Changing the User ID (login as a different
user) clears the presets since they are stored on a per-user basis. Changing control heads does not recall
presets for the previous control head.
Preset button C can be configured via programming to reboot the radio into a particular
application mode. Contact your system administrator to determine if this feature is
enabled in your radio.
7.33
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 edits 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.
48
MM-014716-001, Rev. E
In response, affected radios automatically re-register to receive their edited personalities. During reregistration, subscriber equipment defaults to the emergency profile selected by the administrator.
7.34
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. Scroll through the menu until the “GPS” menu appears in the bottom line of the display.
2. Current GPS coordinate latitude and longitude data continuously scrolls in the top line of the display
in a degrees:minutes:seconds format.
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
also indicates if the data is aged (2 minutes or more) [GPS (Aged) is displayed]
7.35

Primary Functions (Quick Access)
The secondary function of the SCAN button is to toggle the keypad buttons between their primary
function and their secondary function. When the secondary keypad is active, i.e. entering phone digits for
an interconnect call, the SCAN button can be used to toggle the keypad buttons back to their primary
function, perform a task, and then toggle back to finish entering the digits for the phone number.
PRIMARY is displayed when the SCAN button is used to toggle the keypad keys back to their primary
functions. This provides quick access to the primary functions of the keypad. This is a programmable
feature of the SCAN button only. Careful consideration should be given to possible operational conflicts
before enabling this feature.
Several keys on the Scan version have a secondary function. The MENU key is the SELECT secondary
function with the CLEAR key remaining the same for the secondary function. On the System version, the
OPT has a secondary function of DELETE, MENU is SELECT, and CLR retains its CLEAR
functionality.

SELECTION MODE RULES
Many operations require selection from a list such as system, group or phone number. This selection
ramp control, MENU, 0-9, *, #, and the
process is handled in the same manner for all lists. The
CLR button are used during the selection process. The following example systems list is used to explain
the process:
The hookswitch functions the same as the CLR key in I-Call, phone call, and menu
modes.

Line 1 shows the currently selected item name (XXXXXXXX) from the list. Line 2 indicates the list
(YYY) that the selection is to be made from and the number of the selected item (ZZZ) within the list. (In
some cases the information on lines 1 and 2 are exchanged.) Enter the system selection mode by pressing
the SYS key. If SYSTEM 2 is the current selection, the display appears as follows:
SOUTH
SYS
Line 1 contains the current system name, SOUTH; and line 2, SYS = 2, indicates that selection is from
the system list and it is the second system within the list.
A new system from the list is selected by using the
ramp control or by directly entering the system
number with the numeric keys. The
ramp control scrolls through the list in increasing and
ramp control selects the EAST
decreasing order. In the previous example, pressing up with the
system as shown in the next display.

The radio can be programmed to wrap around from one end of a list to the other end or to stop at the ends.
8.4
DIRECT ACCESS
To directly access a selection, enter the corresponding number (e.g., 4) followed by MENU to activate the
selection. The entered number is displayed on line 2 as shown below. Line 1 shows the current list being
used for selection.
SEL SYS
If a mistake is made while entering the number, press the DEL button to backspace once and correct the
entry. If an invalid number is entered, a short low-pitched tone sounds when MENU is pressed.
To exit the selection mode, press the CLR button or wait for the time-out. If the selection mode is cleared
while an entry is pending (i.e., numbers are entered on line 2, but MENU has not been pressed), the entry
on line 2 is disregarded and the previous selection remains active. If the time-out activates while an entry
is pending, the entry on line 2 is selected if it is within the valid range; if it is out of range, the entry on
line 2 is disregarded and the previous selection remains active.
While in system, group or channel selection mode, the radio continues to receive calls
normally and continues scanning, if it is enabled. If a call is received during the
selection mode process the radio returns to the normal receive mode display.
Continuing with the selection process returns the display to the same point in the
selection process if the selection mode time out has not yet expired. Any press of the
PTT button during the selection mode process initiates transmission and exits the
selection mode.

SYSTEM/GROUP/CHANNEL SELECTION
In the following description of SYSTEM/GROUP/CHANNEL SELECTION, the term group is used
for both group and channel.
The M7300 SYSTEM/GROUP/CHANNEL knob and the
ramp control are programmable for
maximum flexibility. If the SYSTEM/GROUP/CHANNEL knob is assigned to select groups, then the
ramp control is assigned to select systems. If the SYSTEM/GROUP/CHANNEL knob is assigned
to select systems, then the
ramp control is assigned to select groups. System, group, and channel
selection is the primary function for these controls.
Either systems or groups can also be selected by entering the select mode and following the selection
mode rules described earlier. The system select or group select modes are entered by pressing SYS or
ramp control after entering a
GRP, respectively, from the standard receive mode. Using the
particular selection mode in this manner is the secondary function of these keys.
8.6.1
System Selection
Several methods, some of which depend on programming, can be used to select a new system. These
procedures are presumed to be starting from the normal receive display.
METHOD 1:
If system selection is programmed to the SYSTEM/GROUP/CHANNEL knob, select a
system by turning the SYSTEM/GROUP/CHANNEL knob to the desired system
position. The display registers the new system name on line 1. If the wrap option is OFF
and the knob is moved to a position greater than the number of programmed systems, the
highest programmed system remains selected.
METHOD 2:
If system selection is programmed as the primary function of the
ramp control,
select a system by pressing up or down to scroll through the system list. The display
registers the new system name on line 1.
METHOD 3:
Press SYS to enter the system select mode and follow the selection mode rules detailed
earlier. Use the
ramp control to scroll through the systems.
57
MM-014716-001, Rev. E
8.6.2
Group and Channel Selection
Several methods, some of which depend on programming, can be used to select a new group or channel.
These procedures assume starting from the normal receive display.
8.7
METHOD 1:
If group selection is programmed to the SYSTEM/GROUP/CHANNEL knob, select a
group by turning the SYSTEM/GROUP/CHANNEL knob to the desired group. The
display registers the new group name on line 2. If the wrap option is OFF and the knob
is moved to a position greater than the number of programmed groups, the highest
programmed group remains selected.
METHOD 2:
If group selection is programmed as the primary function of the
ramp control,
select a group by pressing up or down, to scroll through the group list. The display
registers the new group name on line 2.
METHOD 3:
Press GRP to enter the group select mode and follow the selection mode rules detailed
earlier. Use the
ramp control to scroll through different groups.
LAST SYSTEM/GROUP/CHANNEL RECALL
This feature, enabled through programming, allows the user to recall the last selected system/group after
an emergency or home function or system/group key function. For example, if the Home button (preprogrammed) is pressed, the radio goes to the designated Home system/group or channel. If the Home
button is pressed again, the radio returns to the previous system/group or channel. At this time, the user
can toggle between the Home system/group or channel and the previous system/group or channel. The
operation is the same for the SG1-SG5 buttons.
8.8
DIGITAL VOICE OPERATION (PROVOICE)
8.8.1
Voice Modes
Each system (trunked or conventional) in the radio is programmed for no digital voice operation (analog
only) or digital voice format ProVoice. ProVoice programmed systems have three (3) different voice
modes: clear (analog), digital, and private. The voice modes are programmed on a per-group basis within
each trunked system and on a per-channel basis within each conventional system. A radio must be
equipped with the encrypt/decrypt option before it operates in private mode.
Current ProVoice Conventional operation is for talk-around mode only.

MM-014716-001, Rev. E
8.8.2
Clear Modes
In Clear Mode, the radio transmits and receives only clear (analog) voice signals. These analog signals are
non-digitized and non-encrypted. Clear Mode transmissions can easily be monitored by unauthorized
persons. Groups or channels programmed for clear operation cannot transmit or receive unencrypted
digital or private messages.
8.8.3
ProVoice Digital Mode
ProVoice digital mode allows the radio to transmit and receive digitized voice signals. These digital
signals provide improved weak signal performance and they cannot be easily monitored with a standard
receiver. Groups and channels programmed for ProVoice digital operation transmit only digital signals.
Private calls cannot be received or transmitted when the radio is in ProVoice digital mode because the
radio does not know the cryptographic key used.
Message trunked group calls and individual calls are answered back in the mode they were received,
assuming the call or hang time is still active. Individual, phone, all and emergency calls are transmitted
clear if digital mode is disabled or inoperative.

If receiving an analog message trunked call, the radio responds in analog mode during the hang time
on the working channel.

If receiving an analog I-Call, the radio responds in analog mode during the hang time.

When using the "WHC" feature to respond to an I-Call (after the hang time has expired), the call is
transmitted in the mode defined by the system mode as programmed for the current system if the ID
being called is not in the I-Call list. If the ID is in the I-Call list, then the call is transmitted as defined
by the I-Call mode programmed in the list for that ID.
DTMF
The overdial and hot keypad features for transmitting DTMF tones are not available while in ProVoice
Digital Mode.
ERROR Messages
If any of the following error messages are displayed, the radio was either programmed incorrectly or
needs servicing:
DSP ERR
ERR=xxxx
DSP ERR
DIGV ERR
Power Up Only
If the ProVoice circuit board is not responding correctly, one of the following error messages is displayed
and the radio needs servicing:
HARDWARE
ERR= 3X
3X is a number between 30 and 38
59
MM-014716-001, Rev. E
8.8.4
ProVoice Private Mode
ProVoice 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 the radio was pre-programmed for auto-select, the radio transmits in the following modes;

If Private mode is enabled, transmissions are always in private mode.

If Private mode is disabled and a private call is received, the reply transmission is in Private mode if
the transmission is made during the scan hangtime. If the reply transmission occurs after the scan
hangtime, the transmission is in Clear mode.
When operating on a group or channel programmed for private mode, all transmissions are private and the
radio receives clear and private signals. If the selected group or channel is programmed for auto-select
capability, the mode can be toggled between private and clear with the OPT or OPTION button. Radios
programmed for forced private operation do not allow a change of the transmit mode; therefore, the OPT
or OPTION has no effect.
8.8.4.1 Displaying the Currently Used Cryptographic Key Number
To display the cryptographic key currently in use for either the system encryption key (for special call
such as individual, phone, all, agency or fleet) or the group/channel key (for group or conventional calls),
perform the following procedure (Not Available on Conventional radios):
1. Press the MENU button.
2. Use
to select DISP KEY. Then press the MENU button.
3. Then use
to toggle between displaying the system key or the group/channel key.

8.8.4.2 Key Zero
All cryptographic keys can be zeroed (erased from radio memory) by pressing the CLR button (System
Model) or CLEAR (Scan Model) and while still pressing this button, press and hold the OPT button
(System Model) or OPTION (Scan Model). Press both buttons for 2 seconds. A series of warning beeps
begins at the start of this 2-second period and then switches to a solid tone after the keys have been
zeroed. The display indicates KEY ZERO.
If the cryptographic key(s) are zeroed, one or more keys must be transferred from the Key Loader into the
radio before private communications can continue. Refer to Key Manager TQS3416 Administration and
Software Release Notes for further information.
60
MM-014716-001, Rev. E
8.8.5
Private Operation
8.8.5.1 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 is decrypted, the receiver unsquelches and the message is
heard in the speaker. The selected group or channel must be programmed for private operation and the
correct cryptographic key must be loaded into the radio for this to occur.
8.8.5.2 Transmit an Encrypted Call
1. Select the desired group or channel.
2. Place the radio in private mode by pressing the OPT button (System Model) or OPTION (Scan
Model).
If the last state of the radio was private mode, then private mode is enabled on power up. In addition,
the private mode is enabled if forced operation has been programmed in the radio
If a group or channel is not programmed for private mode operation, PVT DIS is 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 is programmed for forced private transmit operation, FRCD PVT is displayed if an
attempt is made to disable private transmit mode. It is not possible to transmit on this group/channel
in clear mode.
If the radio does not have the correct encryption key loaded, NO KEY # is displayed and the call
does not transmit.
3. Continue with standard transmission procedures. A private mode access tone is heard when the PTT
button is pressed.
8.8.5.3 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 transmits back in the same mode it received the call. For
example, if a clear group is entered in the scan list, it only receives 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 in different modes (clear, digital, private), only the first
occurrence of the group is used.
8.8.6
Conventional Operation
8.8.6.1 Outside Address
The same outside address (works similar to Channel Guard operation) must be programmed in the
transmitting and receiving radios when ProVoice digital or private operation is enabled. If address is not
correct, the radios does not communicate.
8.8.6.2 Channel Guard
Channel Guard encode is transmitted on analog clear channels only. Channel Guard decode operates on
either a clear or private channel. The exception is when G-STAR signaling is used (see Section 8.8.6.3).
61
MM-014716-001, Rev. E
8.8.6.3 G-STAR
When G-STAR is programmed on a private channel, the radio transmits G-STAR in clear mode and then
switches to private for the voice portion of the call. If G-STAR is sent with Channel Guard, then both are
sent in clear mode and the radio switches to private mode. Emergency G-STAR data burst is transmitted
in clear mode.
8.9
MACRO KEY OPERATION
Macro key operation permits the user to accomplish a series of keystrokes with a single "macro"
keystroke. Up to ten (10) macro keys can be defined, each capable of executing up to twenty (20)
keystrokes, to any pushbutton input (i.e., keypad keys, buttons, etc.). Each macro key can be preprogrammed to activate when pressed or when released.
A macro key can also be pre-programmed to change the keystroke sequence the next time the macro key
is activated.
For detail operation and assignment of macro keys, contact your communications supervisor or
administrator.

RECEIVE A CALL
1. Turn the radio on by rotating the POWER ON-OFF/VOLUME knob clockwise (out of detent). A
short alert signal (if enabled through programming) indicates the radio is ready to use.
2. The display shows the last selected or the power up (depending on programming) system and group
names. If the radio is unable to obtain a control channel, line 2 shows CC SCAN.
3. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level.
4. Select the desired system and group. The display indicates the current system and group names.
5. The radio is now ready to receive calls.
6. When the radio receives a group call, it unmutes on the assigned working channel and the BSY
indicator comes on. Line 1 shows GR followed by the logical ID number (if received) of the unit
sending the message, or the associated name if the ID number is found in the individual call list.

SEND A CALL
1. Turn the radio on and set the POWER ON-OFF/VOLUME knob to the desired volume level. Select
the desired system and group.
2. Press and hold the PTT button. The radio displays the system and group names and performs the
necessary signaling required to obtain a communication channel.
3. When the working channel is assigned, TX and BSY indicators are turned ON and a short beep is
sounded indicating communication can begin.
If two or more tones, or a high-pitched tone is heard, the system may be busy and the
call request has been placed in queue or the request has been denied for some reason.
Refer to the Section 9.3 for more details.
4. Hold the microphone approximately 1 ½ inches from the mouth and speak in a normal voice.
5. Release the PTT button when the transmission is complete and listen for a reply.
9.7
CONVENTIONAL FAILSOFT
In the unlikely event of a failure of the EDACS system, communications can take place in conventional
failsoft mode. The radio is automatically directed to a communications channel set up for this purpose.
During this mode of operation, the control unit displays CONV FS in the alphanumeric display. An
increase in activity on the channel during conventional failsoft operation may be noticed, so be careful not
to transmit until the channel is clear.
Operation during conventional failsoft is the same as operation on a conventional system, except that it is
not possible to select a communications channel, or use emergency and special call. When trunking is
restored, the radio is automatically returned to normal operation.
Emergency and Special Call are not operational during conventional failsoft. In
addition, the GRP control does not operate.
9.8
EMERGENCY OPERATION
The radio's ability to declare an emergency, clear an emergency, remain locked on an emergency and
group, and the emergency audio and display freeze can each be enabled or disabled through
programming. When an emergency is declared scanning stops and only restarts after the emergency is
cleared.
9.8.1
Receive an Emergency Call
When receiving an emergency call from the selected group and system, an alert beep sounds and the BSY
indicator illuminates. The message *RXEMER* flashes in the display on line 2 until the emergency
condition is cleared. Follow standard emergency procedures.
9.8.2
Declare an Emergency
To send an emergency call to the selected system and group (or on an optionally pre-programmed
emergency group), proceed as follows:
70
MM-014716-001, Rev. E
1. Press and hold the red emergency button for approximately one second. (This time is programmable
and therefore could be longer or shorter. Check with the system administrator.) The radio transmits 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 (Autokey alert
tone) indicating it is ready for voice transmission. *TXEMER* flashes on line 2 in the display until
the emergency is cleared.
3. Press PTT and speak into the microphone in a normal voice.
4. Release PTT when the transmission is complete and listen for a reply.
5. The emergency can be cleared by pressing and holding the CLR button followed by pressing the red
emergency button then releasing both buttons.
9.9
SYSTEM SCAN OPERATION
The radio can be programmed with the following System Scan features. These features are automatically
enabled upon radio power up. A key or menu option is also defined to allow the System Scan features to
be toggled during radio operation. This is covered in the Menu Selection and Pre-Programmed Keypad
Key sections. The System Scan state is maintained through system changes but defaults to ON at power
up.
9.9.1
Wide Area System Scan
The M7300 Series mobile radio can be programmed for wide area system scan operation for multi-site
applications. 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
switches to the new system and sounds an alert tone.
9.9.2
ProScan™
The radio can be programmed for ProScan™ system scan operation for multi-site applications depending
on the version of radio flash code. 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
compare it with the signal quality of the control channel for each site in its adjacency 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’s
signal quality level degrades below a pre-programmed level, the radio begins to look for a better control
channel. Once a control channel that exceeds the pre-programmed parameters is found, the radio changes
to the new system and emits a tone. If the control channel is completely lost, the radio enters Wide Area
System Scanning and searches the programmed adjacent systems until a suitable control channel is found.
9.9.3
Priority System Scan
The radio can also be programmed for Priority System Scan. (To ensure that this feature operates
correctly, the control channel of the priority system must be located on channel one unless you are using
the ProScan algorithm.) The priority system is the desired or preferred system. While receiving the
control channel of the selected system, the radio periodically leaves the selected system and searches for
the control channel of the priority system at a programmable rate. The programmable rate is defined by
the value in the Priority Scan Time control, (unless the ProScan algorithm is enabled as explained below).
This priority scan timer is reset each time the PTT button is pressed or when a call is received. If the
71
MM-014716-001, Rev. E
priority system control channel is found, or meets the predefined ProScan criteria, the radio automatically
switches to the priority system.
9.9.4
When Wide Area System Scan Is Enabled
If the radio cannot find the control channel of the selected system and begins Wide Area System Scan
(WA Scan), the radio only scans for the priority system control channel if the priority system is in the WA
Scan list.
9.9.5
When ProScan Is Enabled
The radio monitors the priority system and switches to the priority system if the priority system meets the
criteria defined in the “ProScan Options” dialog box. If ProScan is enabled, the rate at which the radio
scans for the priority system is defined by the System Sample Time control.
9.9.6
Menu Selection
Press MENU and then use the
ramp control to scroll through the selections until SYS SCAN is
displayed. Then press MENU to toggle the System Scan state. The SYSC ON or SYSC OFF display
message is displayed for two seconds to show the new state.
9.9.7
Pre-Programmed Keypad Key
Press the pre-programmed key and the SYSC ON or SYSC OFF display message is displayed for two
seconds to show the new state.
9.10
GROUP SCAN OPERATION
Only Groups that are part of the radio's scan list is scanned. Groups are added to the scan list on a per
system basis through programming, the radio keypad, or both, dependent upon programming. This scan
list can be changed by the user from the keypad unless programmed otherwise. Each system's group scan
list is retained in memory when the radio is turned off. The M7300 Series mobile radio can also be
programmed to provide Trunked Priority Group Scan capability, which operates similar to priority scan in
Conventional mode.
The following is a description of programmable scan features that should be helpful in understanding the
Group Scan Operation of the radio:
Scan Hang Time - the delay time the radio waits before resuming scan after the push-to-talk is released
or after the carrier has dropped a channel.
TX Select - the group the radio transmits on while scanning. The radio is programmed to transmit on
either the scanned group or the selected group.
Scan List (privileges) - this feature allows or prohibits scan list changes by the user.
P1 Programming - priority group programming is accomplished by one (and only one) of three methods:

From the keypad, where the Priority programming is not fixed and does not follow the selected
channel,

Priority 1 group programming follows the selected channel, or

Priority 1 group programming is fixed during PC programming and cannot be changed by the user.
P1 Always Scan - determines if the Priority 1 Group is always scanned, regardless of the scan state set by
the user.

and then added back to the scan list. Each new group added to the scan list starts at the lowest
priority. If the Priority 1 and Priority 2 groups are already set and a new group is assigned as Priority
1 or Priority 2, the previously assigned group changes to non-priority scanning.

the system's group scan list in the same manner as if done using the steps above. Deletions performed in
this manner do not remain deleted if the radio is turned off and then back on.
9.10.4 Turn Scan On
1. Toggle scan operation by pressing SCAN. The SCAN indicator turns on when the radio is scanning.
The SCAN key light blinks when temporarily disabled. Scanning stops while the
microphone is off-hook if the hookswitch feature is enabled through programming.
2. When a group on the scan list receives a channel assignment, the radio unmutes on the assigned
channel, the BSY indicator comes on and the received scan group is displayed.

The radio continues scanning if a new group is selected when scan is on.

MM-014716-001, Rev. E

Pressing up with
when scan is on causes the radio to recall the scanned group that was last
received. This group is recalled for a period equal to the scan hang time.
9.10.5 Priority Group Scanning
When scan is enabled and the Priority 1 and Priority 2 groups have been identified, the radio listens to
calls on those groups and the selected group. While receiving a scanned group call, the radio continues to
monitor the selected Priority 1 and Priority 2 groups and drops the call if the selected group or other
higher priority call becomes active. During a Priority 2 call the radio continues to monitor for a Priority 1
group call.
The radio monitors for Agency and Fleet calls that correspond to the Agency and Fleet associated with
the Priority 1 and Priority 2 groups. Priority Agency and Fleet calls are indicated by displaying AGENCY
or FLEET on the System line of the display and associated Priority 1 or 2 group on the Group line of the
display.
9.10.6 Turn Scan Off
Turn scan operation off by pressing SCAN. The radio resumes operation on the selected group.
9.11
INDIVIDUAL CALLS
9.11.1 Receive and Respond to an Individual Call
When the radio receives an individual call (a call directed only to the user's radio), it unmutes on the
assigned working channel and turns on the BSY indicator. Line 1 shows “ID” followed by the logical ID
number of the radio sending the message, or the associated name if the ID number is found in the
individual call list. The individual call indicator displays *INDV* on line 2. The radio can be programmed
to ring when an individual call is received. If enabled, the ring begins five seconds after the caller unkeys
and continues until the PTT button, the CLR button, or IND is pressed.
Hookswitch functions the same as CLR key in I-CALL, phone call, and menu modes.
If a response is made to the call prior to the programmed call-back time-out, the call is directed to the
originating unit. If a response is not made before the call-back time-out, the radio returns to normal
receive mode, but * WHC * is displayed. If the caller's ID is not received, UNKNOWN displays for the
duration of the call and there is no call-back hang time.
To respond after the call-back time-out, press the IND key. The radio's display shows the callers ID on the
first line and WHCI=1 on the second line. Pressing the PTT button at this point initiates an individual call
back to the original caller. (If the last call was a group call, the display shows WHCG=1. Pressing the
PTT button places the call as an individual call.)
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.
74
MM-014716-001, Rev. E
To access the list, press the IND key twice. Use
display the time elapsed since the call was received.
to scroll through the list. Press the MENU key to
9.11.2 Call Storage Lists
There are two lists available for call storage in the radio, the calls received list (1-10) and the personality
list (1-99 as defined by the user). When the individual call mode is entered by pressing IND, the calls
received list is available. The user can toggle to the personality list by selecting any key other than DIS or
toggle between the two lists by pressing the IND key. If wrap is enabled, the calls received list wraps on
itself and not into the other list.
The saved call list shows all ten storage locations. If no calls have been received, the saved call list is
empty and the pre-stored list is available upon entering the individual call mode.
When in the saved call list, pressing MENU toggles the time stamp ON and OFF. The time stamp
indicates how long ago the call was received. The display indicates this information as HH:MM:SS where
HH = hours, MM = minutes and SS = seconds.
When in the pre-stored list, pressing MENU toggles the Logical IDentification (LID) ON and OFF.
9.11.3 Send an Individual Call
The following procedures describe how to initiate and complete an individual call.
1. To select a previously stored individual, select the I-Call mode from the menu or press IND followed
by the
ramp control to scroll through the list of stored individuals. The selection mode rules
75
MM-014716-001, Rev. E
apply. While in the individual call list, the menu key toggles the display between the call name and
the unit ID number. If the individual is not stored in this list but the individual’s unit ID is known, it
can be entered directly from the keypad.
2. Press the PTT button; the radio performs the necessary signaling to obtain a communication channel.
When the signaling is complete and the radio is clear to transmit, TX indicator turns ON and the
channel access tone sounds. Line 1 shows the called individual's name if found in the list of stored
individuals or ID followed by the logical ID number of the unit being called. The message *INDV*
displays on line 2. Proceed with the message.
9.12
SCAT OPERATION
A SCAT™ (Single Channel Autonomous Trunking) System operates with the same set of features as a
standard EDACS system. The only significant user change relates to the BSY indicator. Since only one
channel, operating as both control and working channel, exists in a SCAT System, the BSY indicator is
ON when the SCAT channel is in the working channel mode. When the transmission on the channel is
completed, the indicator turns OFF and indicates the return of SCAT control channel signaling.
9.13
TELEPHONE INTERCONNECT CALLS
9.13.1 Receive a Telephone Interconnect Call (Trunked Mode Only)
Receiving a telephone interconnect call is identical to receiving an individual call. See the DTMF
Overdial Operation section if access to services requiring "over-dial" is needed. Overdial operations are
available for any special call whether it is an individual call or a telephone interconnect call.
9.13.2 Send a Telephone Interconnect Call (Trunked Mode Only)
Use the following procedures to initiate and complete a Telephone Interconnect call:
1. To select a previously stored phone number, select phone call mode from the menu, press PHN and
ramp control to scroll through the list of stored phone numbers. The selection mode
use the
rules apply. While in the phone call list, the MENU key toggles the display between the phone call
name and the phone call number. If the phone number is not stored in this list but the phone number is
known, it can be entered directly from the keypad. If necessary, a pause can be entered by pressing
and holding 0-9, (*), or (#) until an underscore appears in the display.
2. Press and release the PTT button; the radio performs the necessary signaling to obtain a
communication channel. When the signaling is complete and the radio is clear to transmit, TX
indicator turns on and the channel access tone sounds. Line 1 shows the accompanying name if
selected from the list of stored numbers or the phone number if entered directly. The message
*PHONE* is displayed on line 2. The radio then automatically transmits the programmed number
stored in the special call queue.
3. Telephone ringing is heard. When someone answers the phone, press the PTT button and speak into
the microphone. Release the PTT button to listen to the caller. Unsuccessful interconnect signaling
returns the radio to the normal receive mode and the number remains displayed until the special call is
cleared by pressing the CLR button or the time-out expires or another group or system is selected.
4. To terminate the call, momentarily press the CLR button.
76
MM-014716-001, Rev. E
The M7300 Series mobile radio is capable of half-duplex conversation only. The
caller’s message can only be sent if the PTT button is pressed (the radio is
transmitting) and the caller can only be heard by the person being called when the PTT
is released (the radio is receiving).
9.13.3 DTMF Overdial/Conventional Mode Telephone Interconnect
Once the radio has established a connection to the public telephone system, it may be necessary to "overdial" more digits to access banking services, answering machines, credit card calls or other types of
systems that require DTMF (Dual-Tone Multi-Frequency) 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 is the method that is used for making a telephone interconnect call while operating in
the conventional mode but also functions 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 or stored by the operator in the first ten phone list entries. These numbers are accessed by
pressing PHN then following the selection mode rules.
The following steps are required to dial these numbers:
1. Follow the procedure in Sending a Telephone Interconnect Call (Trunked Mode Only) to
establish a connection to the telephone system or consult the system administrator for the procedure
to access a dial tone on the trunked or conventional system.
2. Overdial numbers are transmitted using either method as follows:
METHOD 1:
Press and hold PTT while entering the overdial number sequence from the keypad.
This method sends DTMF tones during individual, telephone interconnect, trunked
group, or conventional channel calls. Anytime the PTT button is pressed and held,
the keypad is enabled for DTMF entry.
METHOD 2:
Press PHN to enter the overdial select/entry mode and follow the selection mode
rules to call up a stored number from the phone list or to directly enter the overdial
digits. Press PTT to send the overdial sequence once. If the number needs to be
transmitted again it must be selected or entered again (this prevents unwanted
numbers from being sent the next time the PTT button is pressed during the call).
This overdial select/entry mode remains active until the call is dropped, cleared, or MENU is pressed. The
overdial select/entry mode can be re-entered if the call is still active by pressing PHN.
9.13.4 Programmable Entries
Individual call ID numbers, telephone numbers and other number sequences for overdialing are stored in
the special call lists when programming the radio. The first ten entry locations of these lists can be
changed by the radio operator. The keypad is used when adding, changing and storing numbers in these
entry locations.
Use the following procedure to store a number in one of the first ten entries of a special call list:
1. Press IND or PHN to enter the individual call list or the phone call list. The selection mode rules
apply.

3. Enter the desired number. If necessary, a pause can be entered by pressing and holding 0-9, (*), or (#)
until an underscore appears in the display. The individual call list entries accept up to 5 digits. The
phone call list entries accept a combination of up to 31 digits and pauses.
4. Press and hold MENU until the display changes indicating that the number has been stored.
5. Repeat the steps above if the number stored in an entry location needs to be changed.
9.14
MOBILE DATA
The M7300 Series mobile radios, when operating in the EDACS configuration, permit either voice or data
calls to be transmitted or received. The radio can handle only one type of call at a time; however,
selection of either data or voice is selected transparently by the operator through normal usage of the
radio. Data communications is not supported in the conventional mode.
The mobile radios can be connected to Mobile Data Terminals (MDT) or to a host computer. Any RS-232
compatible device that supports the Radio Data Interface (RDI) protocol (Version 1.91 or greater) can be
connected to the mobile radio. Support for MDTs or host computers is a programmable option per radio.
Additionally, radios programmed for host computers can also be programmed for data only operation (no
voice calls transmitted or received).
Turn power to the radio OFF before connecting or disconnecting any cables, including
the data cable. Also, turn power to the radio OFF when docking or undocking a
connected laptop computer. Failure to turn the power OFF can damage the radio,
requiring service by a Harris Corporation approved service center.
9.14.1 Displays
The following is displayed on the control unit during the various states of data mode of operation.
TX DATA
Displayed on bottom line of display when the radio is transmitting a data call.
RX DATA

displayed top line of display for 2 seconds then the display returns to normal.

Replacing the microphone into the hookswitch (going on-hook). Only valid if the “DATA OFF”
operation was entered by removing the microphone from the hookswitch (going off-hook).

Clearing an emergency, but valid only if an emergency caused “DATA OFF” operation.
9.14.4 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 conditions
occurs, the data call is immediately terminated and the radio performs the desired function:

The PTT is activated.

The PTT is in Public Address mode.

An emergency is declared by pressing the pre-programmed emergency button.

A group or system change is made.
9.14.5 Scan Lockout Mode
Following the transmission or reception of a data call, if scan is enabled, scanning stops temporarily
(duration pre-programmed). During this time the scan LED flashes to indicate that scan is enabled but
temporarily suspended. This mode is normally exited when the pre-programmed time expires; however,
the following actions terminate the scan lockout mode before the timeout is completed.

The CLR (System Model) or CLEAR (Scan Model) button is pressed.

The PTT is pressed.

A group or system change is made.

Enter phone call mode.


9.14.6 Data Lockout Mode
The data lockout mode is a pre-programmed mode when the radio does not respond to any data channel
assignments and prevents receive data calls from interrupting voice calls. Transmit data calls are still
initiated when needed by the operator. After a pre-programmed time, the radio responds to receive data
calls; however, the following conditions clear the data lockout mode:

STATUS/MESSAGE OPERATION
Status and message operation is possible with either the Scan or System version of the M7300 Series
mobile radio unit. The following procedure is applicable for the System version. For operation with the
Scan version, the four primary keycaps must be reconfigured and pre-programmed for status/message
operation.
9.15.1 Status Operation
Status operation permits the transmission of a pre-programmed status condition to the EDACS site.
To send a status condition, press the STS button (keylight comes on) then press one of the number
buttons (0-9) to select the pre-programmed status. If no status has been programmed for the selected
number button, the radio displays NO ENTRY and the radio sounds a low tone. A valid selection permits
the status text to appear in the display for a pre-programmed time. After the time-out expires or the
MENU button has been pressed (the MENU button overrides the time-out period), the status is selected
and is transmitted to the site or stored in the radio memory where it can be polled by the site at a future
time. If the site receives the status properly, when transmitted or polled by the site, a high-pitched tone
sounds and the keylight associated with that status remains lit. If the site does not receive the status
properly, a low-pitched tone sounds and the keylight associated with the status blinks.
If an incorrect status was selected or the incorrect number button was pressed, the status can be changed
during the pre-programmed time-out period by pressing another number button. The status selection can
also be cancelled by pressing the CLR button prior to the time-out period.
To view the currently selected status after it has been transmitted, press the STS button. If the status was
not sent successfully to the site, the text associated with the status flashes in the display.
The radio can also be pre-programmed to re-designate the keypad buttons for ST0 thru ST9 to send
status condition. In this configuration the radio status operation operates as previously described except
the STS button is not required. The keylight associated with ST0 thru ST9 indicates which status is
selected.
9.15.2 Message Operation
Message operation permits the transmission of a pre-programmed message text to an EDACS site.
To send a message, press the MSG button (keylight comes on) then press one of the number buttons (0-9)
to select the pre-programmed message text. If no message text has been programmed for the selected
number button, the radio displays NO ENTRY and a low-pitched tone sounds. A valid selection permits
the message text to appear in the display for a pre-programmed time. After the time-out expires or the
MENU button has been pressed (the MENU button overrides the time-out period), the message text is
selected and is transmitted to the site. If the site receives the message properly when transmitted, a high
pitched tone sounds and the MSG keylight remains lit. If the site does not receive the message properly, a
low-pitched tone sounds and the MSG keylight blinks.
80
MM-014716-001, Rev. E
If an incorrect message text was selected or the incorrect number button was pressed, the message text
can be changed during the pre-programmed time-out period by pressing another number button. The
message text selection can also be cancelled by pressing the CLR button prior to the time-out period.
To view the currently selected message text after it has been transmitted, press the MSG button and then
the CLR button prior to the time-out period. If the message text was not sent successfully to the site, the
text associated with the message flashes in the display.
9.16
EDACS CONVENTIONAL P1 SCAN
This feature permits the radio user to scan a pre-programmed conventional system and channel as a
Priority 1 (P1) channel while the radio is selected for EDACS trunked system. If activity is detected on
the conventional P1 channel, the radio unmutes and remains on this conventional channel for the
programmable hang time.
The radio must be pre-programmed to designate a button for scan ON/OFF operation.
9.17
DYNAMIC REGROUP OPERATION
Dynamic regroup operation permits multiple talk groups (up to eight) to be added to a radio via the
Communications Systems Director (CSD). The radio must be pre-programmed to respond to regrouping.
Dynamic regrouping is not activated in a radio until an activation message is sent by the system manager.
Each radio that receives and acknowledges regrouping instructions is successfully regrouped.
Pressing and holding the CLEAR (Scan Model) or CLR (System Model) button for 2.5 seconds toggles
the user into and out of the dynamic regroup group set. A double beep sounds for entry or exit. The
display indicates REGR_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 shows NO ENTRY. The radio is prevented from transmitting and receiving calls
in this condition except for scanned groups.
9.17.1 Emergency Operation
If the pre-programmed group set on the currently selected system contains an EMER/HOME group and
the radio is in dynamic regroup, the radio exits dynamic regroup and declares the emergency on the
HOME group. If no EMER/HOME group is present, the radio declares the emergency on the currently
selected dynamic regroup group.
9.18
PAGE (P25 TRUNKED ONLY)
Page sends a PING message to a radio and functions similar to Individual Call.
The following procedures describe how to initiate and complete a Page.
1. To select a previously stored individual, select the Page mode from the menu followed by the
ramp control to scroll through the list of stored individuals. The selection mode rules apply. While in
the individual call list, the MENU key toggles the display between the call name and the unit ID
number. On System model radios, the individual’s unit ID can also be entered directly from the
keypad.
2. Press the PTT button; the radio performs the necessary signaling on the control channel. On the
calling radio, line 1 shows the called individual's name if found in the list of stored individuals or ID
followed by the logical ID number of the unit being called. If the receiving radio receives the Page
and responds, both radios emits three high-pitched tones. The receiving radio also displays PAGE and
the ID of the calling radio.

3. Select the desired conventional system and channel. The display indicates the current conventional
system and channel names.
4. The radio is now ready to receive calls.
5. When the radio receives a call (and the correct encoding is decoded, if programmed and enabled), it
unmutes on the channel and the BSY indicator comes on.
10.6
SEND A CALL
1. Turn ON the radio and set the POWER ON-OFF/VOLUME knob to the desired volume level.
Select the desired conventional system and channel.
2. Ensure that the channel is not busy by pressing the CLR button to briefly disable any channel
decoding and unmute the receiver or observe the unlit BSY indicator. If the Channel Busy Lockout
feature is programmed for the selected channel, the radio does not transmit when the channel is busy.
3. Press and hold the PTT button. The TX indicator turns on and a short beep sounds (if programmed)
indicating that communication can begin.
4. Hold the microphone approximately 1 ½ inches from the mouth and speak in a normal voice.
5. Release the PTT button when the transmission is complete and listen for a reply.
10.7
EMERGENCY OPERATION
If enabled, G-STAR emergency signaling can be transmitted when operating in the conventional mode.
This G-STAR signaling transmits five (5) times with a delay between each transmission. To send an
emergency call on the selected conventional system and channel (or on an optionally pre-programmed
conventional emergency system and channel), proceed as follows:
Press and hold the red Emergency button for approximately one second (this time is programmable and,
therefore, could be longer or shorter; check with the system administrator). The radio turns on the TX
indicator and proceeds to transmit the pre-programmed G-STAR emergency signaling sequence.
G-STAR is programmed to transmit in one of the following methods:
METHOD 1: G-STAR is transmitted on the selected channel. If the channel is changed the emergency
signaling continues to be transmitted on the newly selected channel.
METHOD 2: Same as METHOD 1 but the radio locks on to the currently selected channel. Attempts to
change the system or channel are disabled.
METHOD 3: G-STAR is transmitted on a pre-programmed conventional emergency system and
channel regardless of the selected channel. In this case the selected channel is available
for voice transmission and the radio periodically changes to the pre-programmed
emergency system and channel to send the emergency signaling and then changes back to
the selected channel.
METHOD 4: Same as METHOD 3, but the radio locks on to the pre-programmed emergency system
and channel. Attempts to change the system or channel are disabled.
87
MM-014716-001, Rev. E
The emergency state can be cleared by turning the radio OFF and then back ON.
10.7.1 Use 5-Tone Signaling to Declare an Emergency
If 5-Tone signaling is defined for emergency declaration in place of G-STAR emergency signaling, a preprogrammed tone sequence is transmitted instead of the G-STAR sequence. This emergency declaration
functions as the G-STAR emergency in all other respects.
10.7.2 Tone Encode Transmission
In conventional mode, two keys can be defined to be tone encode triggers. If either one of the preprogrammed tone encode triggers is pressed, a pre-programmed tone sequence is transmitted on the
current system and channel. (See Section 10.7 if the emergency key is used.) The TX indicator lights
during tone transmission and a beep sounds at the end of the transmission. If enabled, audible side tones
are heard in the radio speaker as well. If PTT is pre-programmed as one of the triggers, the microphone
becomes active for voice communication after the tone sequence is complete.
Tone encode is transmitted with Channel Guard if one is defined, and tones are always transmitted in
clear voice mode, even if the channel is set for digital or private (see VOICE MODES). Digital or private
voice transmission resumes normally after the tone transmission.
10.8
SCAN CONVENTIONAL CHANNELS
Channels, which have been previously added to the scan list on a per system basis, can be scanned. The
selected channel is scanned (if enabled through programming) whether or not it is in the scan list. Each
conventional system's channel scan list is retained in memory when the radio is turned OFF.
The scan rate varies depending upon the number of channels in the scan list and whether or not the radio
is programmed to scan for channels with decoding enabled. Fewer channels results in a faster scan rate. If
programmed for dual-priority scan operation, the priority 1, priority 2 and the remaining scan list
channels are scanned. Once a signal is detected and the correct encoded squelch signal is decoded (if
programmed), the radio receives the message and displays the received scan channel. At the same time,
scanning continues on the priority 1 and priority 2 channels. If a priority 1 or priority 2 channel carrier,
regardless of encoded squelch decoding, is detected while a non-priority channel is being received, the
display name is updated and the received channel is switched to the priority channel. Scanning of the
priority-one channel continues if a message is being received on the priority 2 channel.
While receiving a call on a non-priority or a priority 2 channel, the radio periodically checks the priority 1
and 2 channels. If Scan with Channel Guard is enabled, the radio uses Channel Guard to decide whether
to unmute on a priority channel. The radio stops, on squelch detection, on a priority channel. In normal
operation, the radio unmutes only on detecting the correct Channel Guard; otherwise, it remains muted
until the priority channel call and hang time have ended. An optional feature allows the radio to continue
scanning upon the detection of the wrong Channel Guard on a priority channel. The user can then select
the rate at which this channel is scanned until the call ends.

10.11 SQUELCH ADJUST
In the conventional mode of operation, the squelch can be re-adjusted in the MENU selection mode or
from a front panel key on the keypad that has been pre-programmed. A default value of 9, or any user
level between 1 and 16, can be selected using programming software. The user can change this setting
either of two ways from the front panel keys.
A value of 16 requires a strong signal to open squelch, a value of 2 requires a very weak
signal to open squelch, and a value of 1 is open squelch.
When the squelch adjust feature is activated, Channel Guard, T99 decode, and Scan are
disabled. When the squelch adjust feature is exited, Channel Guard, T99 decode, and
Scan are restored to their previous states.

10.12 TYPE 99 DECODE
If the Type 99 Decode Option has been pre-programmed, individual selective calling is possible. The
radio can now decode individual, group or supergroup paging calls. Two sets of Type 99 paging codes
must be pre-programmed into the radio. When the radio decodes an appropriate Type 99 code sequence,
an alert tone and visual indicator is provided to the user. The receiver then operates as a noise squelched
unit until Type 99 is reset. Type 99 decode continues to operate during this noise squelched period. The
appropriate Type 99 alert tone sounds again if it detects a valid two-tone sequence.
Type 99 operation can be reset manually or automatically (pre-programmed). Manual reset is achieved by
briefly pressing CLR, if programmed. Automatic reset, if enabled, occurs after a 30 second interval
following the most recent decode of a Type 99 tone sequence. Hookswitch (pre-programmed) can also
enable or disable Type 99 decode. The pre-programmed key light blinks when Type 99 is disabled by the
hookswitch.

A.
Harris Corporation, a Delaware Corporation, through its RF Communications Division (hereinafter "Seller") warrants to the
original purchaser for use (hereinafter "Buyer") that Equipment manufactured by or for the Seller shall be free from defects in
material and workmanship, and shall conform to its published specifications. With respect to all non-Seller Equipment, Seller
gives no warranty, and only the warranty, if any, given by the manufacturer shall apply. Rechargeable batteries are excluded
from this warranty but are warranted under a separate Rechargeable Battery Warranty (ECR-7048).
B.
Seller’s obligations set forth in Paragraph C below shall apply only to failures to meet the above warranties occurring within the
following periods of time from date of sale to the Buyer and are conditioned on Buyer’s giving written notice to Seller within thirty
(30) days of such occurrence:
1.
2.
3.
4.
5.
for fuses and non-rechargeable batteries, operable on arrival only.
for parts and accessories (except as noted in B.1) sold by Seller’s Service Parts Operation, ninety (90) days.
for P7300, P7200, P7100IP, P5400, P5300, P5200, P5100, P3300, M7300, M7200 (including V-TAC), M7100 IP, M5300 and
M3300 radios, two (2) years, effective 10/01/2007.
for UnityTM XG-100P, three (3) years.
for all other equipment of Seller’s manufacture, one (1) year.
C.
If any Equipment fails to meet the foregoing warranties, Seller shall correct the failure at its option (i) by repairing any defective or
damaged part or parts thereof, (ii) by making available at Seller’s factory any necessary repaired or replacement parts, or (iii) by
replacing the failed Equipment with equivalent new or refurbished Equipment. Any repaired or replacement part furnished
hereunder shall be warranted for the remainder of the warranty period of the Equipment in which it is installed. Where such
failure cannot be corrected by Seller’s reasonable efforts, the parties will negotiate an equitable adjustment in price. Labor to
perform warranty service will be provided at no charge during the warranty period only for the Equipment covered under
Paragraph B.3 and B.4. To be eligible for no-charge labor, service must be performed at Seller’s factory, by an Authorized
Service Center (ASC) or other Servicer approved for these purposes either at its place of business during normal business hours,
for mobile or personal equipment, or at the Buyer’s location, for fixed location equipment. Service on fixed location equipment
more than thirty (30) miles from the Service Center or other approved Servicer’s place of business will include a charge for
transportation.
D.
Seller’s obligations under Paragraph C shall not apply to any Equipment, or part thereof, which (i) has been modified or otherwise
altered other than pursuant to Seller’s written instructions or written approval or, (ii) is normally consumed in operation or, (iii) has
a normal life inherently shorter than the warranty periods specified in Paragraph B, or (iv) is not properly stored, installed, used,
maintained or repaired, or, (v) has been subjected to any other kind of misuse or detrimental exposure, or has been involved in
an accident.
E.
The preceding paragraphs set forth the exclusive remedies for claims based upon defects in or nonconformity of the Equipment,
whether the claim is in contract, warranty, tort (including negligence), strict liability or otherwise, and however instituted. Upon the
expiration of the warranty period, all such liability shall terminate. The foregoing warranties are exclusive and in lieu of all other
warranties, whether oral, written, expressed, implied or statutory. NO IMPLIED OR STATUTORY WARRANTIES OF
MERCHANTABILITY OR FITNESS FOR PARTICULAR PURPOSE SHALL APPLY. IN NO EVENT SHALL THE SELLER BE
LIABLE FOR ANY INCIDENTAL, CONSEQUENTIAL, SPECIAL, INDIRECT OR EXEMPLARY DAMAGES.
This warranty applies only within the United States.
