A QT tone/ DQT code is a sub-audible tone/code which allows you to ignore (not hear)

calls from other parties who are using the same channel.

Operator Selectable Tone

If a key has been programmed with [OST], you can reprogram the QT/DQT settings on

each of your channels.

1 Select your desired channel.

2 Press and hold the key programmed as [OST] for 1 second.

3 Press the / key to select your desired tone or code.

• Your dealer can set up to 40 tones/codes.

4 When you have finished operating using OST, press the [OST] key again to turn the

OST function OFF.

■ Radio Access Number (RAN)

RAN is a new signaling system designed for digital radio communications.

When a channel is set up with a RAN, squelch will only open when a call containing

a matching RAN is received. If a call containing a different RAN is made on the same

channel you are using, you will not hear the call. This allows you to ignore (not hear)

calls from other parties who are using the same channel.

■ Optional Signaling

Your dealer may also program several types of optional signaling for your transceiver

channels.

2-tone Signaling: 2-tone Signaling opens the squelch only when your transceiver

receives a call containing matching 2 tones.

DTMF Signaling: DTMF Signaling opens the squelch only when the transceiver

receives a call containing a matching DTMF code.

FleetSync Signaling: Refer to “SELCALL (SELECTIVE CALLING)” on page XX.

NXDN ID Signaling: NXDN ID is an optional signaling system available only for digital

communications.

MONITOR/ SQUELCH OFF

You can use the key programmed as [Monitor] or [Squelch Off] to listen to weak signals

that you cannot hear during normal operation and to adjust the volume when no signals are

present on your selected channel.

• The

icon appears on the display while Monitor or Squelch Off is activated.

Your dealer can program a key with one of four Monitor/Squelch Off functions:

• Monitor: Press to deactivate QT, DQT, DTMF, 2-tone, or FleetSync Signaling. Press

again to return to normal operation.

• Monitor Momentary: Press and hold to deactivate QT, DQT, DTMF, 2-tone or

FleetSync Signaling. Release to return to normal operation.

• Squelch Off: Press to hear background noise. Press again to return to normal

operation.

• Squelch Off Momentary: Press and hold to hear background noise. Release to

return to normal operation.

■ Squelch Level

If a key has been programmed as [Squelch Level], you can readjust your transceiver’s

squelch level:

1 Press the key programmed as [Squelch Level].

• The

icon appears on the display, along with the current squelch level.

2 Press the / key to select your desired squelch level from 0 to 9.

3 Press the C> key to store the new setting.

SIGNAL STRENGTH INDICATOR

The signal strength indicator displays the strength of received calls. No icon appears when

no signal is available.

Strong Sufficient Weak Very weak

flashes when out of range (NXDN Trunking only).

PUBLIC ADDRESS (PA)

The PA system can only be used with an external speaker.

1 Press the key programmed as [Public Address] to activate the Public Address

function.

• The icon appears on the display.

2 Press and hold the PTT switch, then speak into the microphone to make your address

through the external speaker.

3 Press the [Public Address] key again to exit Public Address.

HORN ALERT

Press the key programmed as [Horn Alert] to toggle the Horn Alert function ON or OFF.

• The icon appears on the display while Horn Alert is activated.

EXTERNAL SPEAKER

After attaching an external speaker to the transceiver, p

ress the key programmed as

[External Speaker] to output all received signals through the external speaker.

• The icon appears on the display.

Press the [External Speaker] key again to output all received signals only through the

built-in speaker.

DISPLAY BRIGHTNESS

You can cycle the display brightness between high, low, and off by pressing the key

programmed as [LCD Brightness].

BACKGROUND OPERATIONS

TIME-OUT TIMER (TOT)

The Time-out Timer prevents you from using a channel for an extended duration. If you

continuously transmit for a preset time, the transceiver will stop transmitting and an alert

tone will sound. Release the PTT switch.

AUXILIARY PORT

Press the key programmed as [AUX A] or [AUX B] to activate the auxiliary port. The

auxiliary port is used with optional boards.

• The icon appears on the display when the auxiliary A port is active.

• The icon appears on the display when the auxiliary B port is active.

BUSY CHANNEL LOCKOUT (BCL)

If BCL is set up by your dealer, you will be unable to transmit if the channel is already in

use.

• “BUSY” appears on the display when you press the PTT switch. Use a different

channel or wait until the channel becomes free.

If your dealer has programmed BCL Override for your transceiver, you can override the

BCL by pressing the PTT switch again, immediately after releasing it, when the channel is

busy.

CONTROL CHANNEL HUNT

On digital Trunking channels, the transceiver automatically searches for a control channel.

• While searching for a control channel, the antenna icon will flash (types I and II only)

and no signals can be received.

PTT ID

PTT ID is the transceiver unique ID code which is sent each time the PTT switch is pressed

and/or released.

COMPANDER

If programmed by your dealer for a channel, the compander will remove excessive noise

from transmitted signals, providing higher clarity of signals.

TRANSMIT POWER

Your dealer has programmed a transmit power level for each channel. Power levels can

be high, medium, or low.

MANDATORY SAFETY INSTRUCTIONS TO INSTALLERS AND USERS

• Use only manufacturer or dealer supplied antennas.

• Antenna Minimum Safe Distance: 40 cm (16 inches), 50% duty Cycle.

• Antenna Gain: 0 dBd referenced to a dipole.

The Federal Communications Commission has adopted a safety standard

for human exposure to RF (Radio Frequency) energy which is below the

OSHA (Occupational Safety and Health Act) limits.

•

Antenna Mounting: The antenna supplied by the manufacturer or radio

dealer must not be mounted at a location such that during radio transmission,

any person or persons can come closer than the above indicated minimum

safe distance to the antenna, i.e. 40 cm (16 inches) , 50% duty Cycle.

• To comply with current FCC RF Exposure limits, the antenna must

be installed at or exceeding the minimum safe distance shown

above, and in accordance with the requirements of the antenna

manufacturer or supplier.

•

Vehicle installation: The antenna can be mounted at the center of a

vehicle metal roof or trunk lid, if the minimum safe distance is observed.

• Base Station Installation: The antenna should be fixed-mounted on

an outdoor permanent structure. RF Exposure compliance must be

addressed at the time of installation.

Antenna substitution: Do not substitute any antenna for the one supplied

or recommended by the manufacturer or radio dealer.

You may be exposing person or persons to excess radio frequency radiation.

You may contact your radio dealer or the manufacturer for further instructions.

Maintain a separation distance from the antenna to person(s) of

at least 40 cm (16 inches), 50% duty Cycle.

“This transmitter is authorized to operate with a maximum duty factor of 50%, in

typical push-to-talk mode, for satisfying FCC RF exposure compliance requirements.”

You, as the qualified end-user of this radio device must control the exposure

conditions of bystanders to ensure the minimum separation distance (above) is

maintained between the antenna and nearby persons for satisfying RF Exposure

compliance. The operation of this transmitter must satisfy the requirements of
