2 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.
NOTE
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.
CAUTION
Changes or modifications not expressly approved by Harris Corporation could void the
user's authority to operate the equipment.
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 Unity 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 Unity two-way radio has an RF exposure product label. Also, your Unity Installation and
Operator’s Manuals include information and operating instructions required to control your RF exposure
and to satisfy compliance requirements.
14221-1200-2000

2.2 COMPLIANCE WITH RF EXPOSURE STANDARDS
Your Harris Corporation Unity mobile two-way radio is designed and tested to comply with a number of
national and international standards and guidelines (listed below) regarding human exposure to RF
electromagnetic energy. This radio complies with the IEEE and ICNIRP exposure limits for
occupational/controlled RF exposure environment at duty factors of up to 50% talk-50% listen and is
authorized by the FCC for occupational use. In terms of measuring RF energy for compliance with the
FCC exposure guidelines, your radio antenna radiates measurable RF energy only while it is transmitting
(talking), not when it is receiving (listening) or in standby mode.
Your Harris Corporation Unity mobile two-way radio complies with the following RF energy exposure
standards and guidelines:
• United States Federal Communications Commission (FCC), Code of Federal Regulations; 47 CFR §§
2 sub-part J.
• American National Standards Institute (ANSI)/Institute of Electrical and Electronic Engineers (IEEE)
C95.1-2005.
• Institute of Electrical and Electronic Engineers (IEEE) C95.1-2005.
• IC standard RSS-102, Issue 2, 2005: “Spectrum Management and Telecommunications Radio
Standards Specification. Radiofrequency Exposure Compliance of Radiocommunication Apparatus
(All Frequency Bands).
CAUTION
Table 2-1 lists the recommended minimum lateral distance for a controlled environment
and for unaware bystanders in an uncontrolled environment, from transmitting types of
antennas (i.e., monopoles over a ground plane, or dipoles) at rated radio power for

3 OPERATION SAFETY RECOMMENDATIONS
3.1 TRANSMITTER HAZARDS
WARNING
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 anti-
skid 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)
• 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.
14221-1200-2000

4 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 Unity 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.
NOTE
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.
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.

interfaces can be handled via the control head connected to the radio unit via a 3-wire Controller Area
Network (CAN) cable. Two CH-721 control heads may be attached to the XG-100M. 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 an additional
remote control head, the following features are available from both positions:
• Either control head can initiate a call but only one can talk at a time. The other connected control
head hears both sides of the conversation.
• Incoming and outgoing audio can be heard.
• Independent audio control is available.
• Radio settings such as talk group, scan mode etc., can be controlled by either control head.

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 pre-
programmed 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 system administrator.
6.12 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. If the radio is
unable to obtain a control channel, line 2 shows CC SCAN.
2. Adjust the POWER ON-OFF/VOLUME knob to the desired volume level.
3. Select the desired system and group/channel. The display indicates the current system and
group/channel names.
4. The radio is now ready to receive calls.
5. When the radio receives a 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.
6.13 TRANSMIT 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.
NOTE
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 0 for more details.
4. Hold the microphone approximately 2 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.
6.14 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 restarts after the emergency is cleared.
14221-1200-2000
24
6.14.1 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.
By default, The ID of the radio declaring an emergency appears in the display until the emergency
hangtime expires. After the hangtime expires, the radio displays emergency (with no ID) until the
emergency is cleared. If enabled via radio programming, the radio continues to display the ID of the radio
declaring the emergency until the emergency is cleared.
6.14.2 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:
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 – see Table 6-4) 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.
6.14.3 Emergency Lock
If Emergency Lock is enabled via radio programming, the radio locks on the group or channel after an
emergency is declared. The radio user cannot change to another group or channel until the emergency is
cleared.
6.15 ENCRYPTION
The XG-100M mobile radio supports AES, DES-OFB, and DES-CFB encryption. Encryption protects
against unauthorized reception and use of radio communications. DES encryption uses 56-bit keys, while
AES uses 128, 192, or 256-bit keys. Since every additional bit doubles the number of keys that must be
attempted for decoding, this makes AES significantly more robust than DES.
When operating on a group or channel programmed for encryption, all transmissions are encrypted. The
radio receives unencrypted and encrypted signals.
To enable or disable encryption for the system/group/channel displayed:
1. Scroll through the menu until PRIVATE is displayed.
2. Press the MENU button to toggle between encrypted and unencrypted.
Or
A button on the control head or HHC can be programmed to toggle encryption on or off.
appears on the display when encryption is enabled.
14221-1200-2000
25
6.16 WIDE AREA SYSTEM SCAN (TRUNKED ONLY)
The Unity mobile radio can be programmed for Wide Area System Scan (WA 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.
If the radio cannot find the control channel of the selected system and begins WA Scan, the radio only
scans for the priority system control channel if the priority system is in the WA Scan list.
1. Press MENU and then use the ramp control to scroll through the selections until SYS SCAN
is displayed.
2. Press MENU to toggle the System Scan state.
3. The SYSC ON or SYSC OFF display message is displayed for two seconds to show the new state.
6.17 PROSCAN
The radio can be programmed for ProScan system scan operation for multi-site applications. 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.
6.18 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. 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 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 priority system control
channel is found, or meets the predefined ProScan criteria, the radio automatically switches to the priority
system.
6.18.1 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.
6.18.2 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.
14221-1200-2000
26
6.19 SCAN OPERATION
Only groups or channels that are part of the radio's scan list are scanned. Groups/channels are added to the
scan list on a per system basis through programming, the radio keypad, or both, dependent upon
programming. The scan list can be changed by the user from the keypad unless programmed otherwise.
Each system's scan list is retained in memory when the radio is turned off.
The following is a description of programmable scan features that should be helpful in understanding the
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.
Transmit 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 1 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.
• Follows the selected channel.
• 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.
P2 Programming – priority 2 programming is accomplished by one two methods:
• From the keypad, where the Priority programming is not fixed and does not follow the selected
channel.
• Fixed during PC programming and cannot be changed by the user.
6.19.1 Vote Scan
If vote scan is enabled via RPM, the radio automatically selects the strongest signal ensuring that the best
audio quality is delivered to the user. If vote scan is enabled, the radio is always scanning. You cannot
stop scanning, start normal scanning, or monitor the channel.
NOTE
If Talk-Around is enabled, Vote Scan is turned off.
6.19.2 Add Groups/Channels to Scan List
1. With scan operation turned off, select the desired group/channel to add to the selected scan list.
2. Press (+) or (-) with to display the current priority status of the group on line 1 for a time-out
period.
3. While the status is displayed, press (+) with to add the group to the scan list. is displayed.
This sets the selected group/channel for non-priority scanning.
14221-1200-2000
27
4. Press (+) with a second time to set the group to Priority 2. is displayed.
5. Press (+) with a third time to set the group to Priority 1. is displayed in column 1, line 1.
The priority level selection sequence only advances the group to the next higher priority level and
stops at priority level 1. To select a lower priority level, the group must be deleted from the scan list
and then added back to the scan list. Each new group added to the scan list starts at the lowest
priority. If the Priority 1 and Priority 2 groups are already set and a new group is assigned as Priority
1 or Priority 2, the previously assigned group changes to non-priority scanning.
6.19.3 Delete Groups/Channels from Scan List
1. With scan operation turned off, select the desired group/channel to delete from the selected trunked
system's group scan list.
2. Press (+) or (-) with . The current scan status of the group is displayed for a time-out period.
3. Press (-) with to delete the group from the scan list. , or turns off. Any group that is
not in a scan list shows a blank when it is the selected channel.
6.19.4 Nuisance Delete
A group or channel can also be deleted from the scan list, if it is not the currently selected group by
pressing (-) with during scan operation while the radio is displaying the unwanted group or
channel. The group or channel is deleted from the scan list in the same manner as using the steps above.
Deletions performed in this manner do not remain deleted if the radio is turned off and then back on.
6.19.5 Turn Scan On
1. Toggle scan operation by pressing SCAN. The SCAN indicator turns on when the radio is
scanning.
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.
• Pressing the PTT button when scan is on causes the radio to transmit on the displayed group or on
the currently selected group depending on programming.
• 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.
6.19.6 Priority Scanning
When scan is enabled and the Priority 1 and Priority 2 groups/channels have been identified, the radio
listens to calls on those groups/channels and the selected group/channel. While receiving a scanned call,
the radio continues to monitor the selected Priority 1 and Priority 2 groups/channels and drops the call if
the selected group/channel or other higher priority call becomes active. During a Priority 2 call the radio
continues to monitor for a Priority 1 call.
6.19.7 Turn Scan Off
Turn scan operation off by pressing SCAN. The radio resumes operation on the selected group.

6.20 INDIVIDUAL CALLS (P25 MODES ONLY)
6.20.1 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.
NOTE
Hookswitch functions the same as CLR key in I-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.
To access the list, press the IND key twice. Use to scroll through the list. Press the MENU key to
display the time elapsed since the call was received.
6.20.2 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.
14221-1200-2000
29
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.
6.20.3 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
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.
6.21 STATUS/MESSAGE OPERATION (P25 TRUNKED)
Status and message operation is possible with either the Scan or System version of the Unity 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.
6.21.1 Status Operation
Status operation permits the transmission of a pre-programmed status condition to the P25 Trunked 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.
14221-1200-2000
30
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.
6.21.2 Message Operation
Message operation permits the transmission of a pre-programmed message text to a P25 Trunked 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.
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.
6.22 SQUELCH ADJUST (CONVENTIONAL)
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.
NOTE
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.
NOTE
When the squelch adjust feature is activated, Channel Guard and Scan are disabled. When
the squelch adjust feature is exited, Channel Guard and Scan are restored to their previous
states.
6.22.1 Menu Selection
1. Press the MENU key and then use the ramp control to scroll through the selections until
SQUELCH is displayed. Then press MENU (select) again.

2. The display shows SQLCH=xx, where "xx" is the value between 1 and 16.
3. Use the ramp control to scroll through the values. Then press the MENU (select) key to save
the new value after the display time-out (2 seconds). The displayed value is selected and saved.
4. If the MENU or CLR key is pressed before the time-out, the menu feature exits and the squelch level
is not updated. The original value is restored.
6.22.2 Pre-Programmed Keypad Key
1. Press the pre-programmed key and the display indicates SQLCH=xx, where "xx" is the value
between 1 and 16.
2. Use the ramp control to scroll through the values. Then press MENU to save the new value
or wait for the display time-out (2 seconds). The displayed value is selected and saved.
3. If the CLR key is pressed before the time-out, the squelch level is not updated and the original value
is restored.
6.23 TALK-AROUND (CONVENTIONAL)
Talk-around provides short range, line of sight communications.
1. Make sure the radio is ON and then select the desired conventional system and channel.
2. If enabled via programming, press MENU and then use the ramp control to scroll through the
selections until TALKARND is displayed. Press MENU again to toggle talk-around ON
or
Press the pre-programmed button to toggle the talk-around function ON.
3. Ensure that the channel is not busy by pressing the CLR (System version) or CLEAR (Scan version)
to briefly disable any channel decoding and unmute the receiver or observe the unlit BSY indicator. If
the TX Busy feature is programmed for the selected channel, the radio does not transmit when the
channel is busy.
4. Press and hold the PTT button. The TX indicator illuminates and a short beep sounds (if pre-
programmed) indicating that communication can begin.
5. Release the PTT button when the transmission is complete and listen for a reply.
6. When the communication is completed, press the pre-programmed button to toggle the talk-around
function OFF.
