Various electronic equipment in your vehicle may malfunction if they are not properly protected from the radio frequency energy which is present while transmitting. Typical examples include electronic fuel injection, anti-skid braking, and cruise control. If your vehicle contains such equipment, consult the dealer for the make of vehicle and enlist his/her aid in determining if they will perform normally while transmitting.

■ Power Cable Connection

The transceiver operates in 12 V negative ground systems only! Check the battery polarity and voltage of the vehicle before installing the transceiver.

1 Check for an existing hole, conveniently located in the ﬁ rewall, where the power

cable can be passed through.

• If no hole exists, use a circle cutter to drill a hole, then install a rubber grommet.

2 Run the power cable through the ﬁ rewall and into the engine compartment. 3 Connect the red lead to the positive (+) battery terminal and the black lead to the

negative (–) battery terminal.

• Place the fuse as close to the battery as possible.

4 Coil the surplus cable and secure it with a retaining band.

• Be sure to leave enough slack in the cables so the transceiver can be removed for servicing while keeping the power applied.

■ Installing the Transceiver

For passenger safety, install the transceiver securely using the supplied mounting bracket and screw set, so the transceiver will not break loose in the event of a collision.

Note: Before installing the transceiver, check how far the mounting screws will extend below the surface. When drilling mounting holes, be careful not to damage vehicle wiring or parts.

1 Mark the position of the holes in the dash, using the mounting bracket as a

template. Using a 4.2 mm (5/32 inch) drill bit, drill the holes, then attach the mounting bracket using the supplied screws.

• Mount the transceiver within easy reach of the user and where there is sufﬁ cient space at the rear of the transceiver for cable connections.

2 Connect the antenna and the supplied power cable to the transceiver. 3 Slide the transceiver into the mounting bracket and secure it using the supplied hex-

headed screws.

4 Mount the microphone hanger in a location where it will be within easy reach of the

user.

• The microphone and microphone cable should be mounted in a place where they will not interfere with the safe operation of the vehicle.

When replacing the fuse in the DC power cable, be sure to replace it with a fuse of the same value. Never replace a fuse with one that is rated with a higher value.

ADVANCED OPERATIONS

EMERGENCY CALLS

If your transceiver has been programmed with the Emergency function, you can make emergency calls.

1 Press and hold the key programmed as [Emergency].

• Ask your dealer for the length of time necessary to hold this key before the

transceiver enters Emergency mode.

• When the transceiver enters Emergency mode, it will change to the Emergency

channel and begin transmitting based on how it is set up by your dealer.

2 To exit Emergency mode, press the [Emergency] key again.

• If the Emergency mode completes a preset number of cycles, Emergency mode will

automatically end and the transceiver will return to the zone and channel that was in use before Emergency mode was entered.

Note:

◆ Your dealer can set the transceiver to emit a tone when transmitting in Emergency mode.

◆ Your dealer can set the transceiver to emit tones and received signals as normal, or mute the

speaker during Emergency operation.

SIGNALING

■ Quiet Talk (QT)/ Digital Quiet Talk (DQT)

Your dealer may have programmed QT or DQT signaling on your transceiver channels.

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 (OST)

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

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

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

OST function OFF.

/ key to select your desired tone or code.

■ Radio Access Number (RAN)

RAN is a 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 (available only for NX-720H/ NX-720HG/ NX-820H/ NX-820HG).

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 10. 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.
