RWARNING! NEVER connect the transceiver to an

AC outlet. This may pose a ﬁre hazard or result in an electric

shock.

RWARNING! NEVER operate the transceiver while

driving a vehicle. Safe driving requires your full attention—

anything less may result in an accident.

NEVER connect the transceiver to a power source of more

than 16 V DC. This connection will ruin the transceiver.

NEVER connect the transceiver to a power source using

reverse polarity. This connection will ruin the transceiver.

NEVER cut the DC power cable between the DC plug and

fuse holder. If an incorrect connection is made after cutting,

the transceiver might be damaged.

NEVER place the transceiver where normal operation of

the vehicle may be hindered or where it could cause bodily

injury.

NEVER let objects impede the operation of the cooling fan

on the rear panel.

DO NOT push the PTT when not actually desiring to transmit.

IMPORTANT

READ ALL INSTRUCTIONS carefully and completely before

using the transceiver.

■ Antenna installation

D Antenna location

To obtain maximum performance from the transceiver, select

a high-quality antenna and mount it in a good location. A non-

radial antenna should be used when using a magnetic mount.

D Antenna splitter

You can use a dual band antenna because a duplexer is in-

stalled in the transceiver. However, an external duplexer must

be connected when using a separate antenna for each band.

D Antenna connector

The antenna uses a PL-259 connector.

PRIORITY WATCH

■ Priority watch types

Priority watch checks for signals on a memory or call chan-

nel every 5 sec. while operating on a VFO frequency. The

transceiver has 3 priority watch types to suit your needs. You

can transmit on the VFO frequency while the priority watch

operates.

The watch resumes according to the selected scan resume

condition. See p. 46 for details.

NOTE:

• Priority watch cannot be started from a scratch pad

memory.

• The DTMF memory encoder or optional pager/code

squelch are turned OFF when priority watch starts.

• If the optional pocket beep function is activated, the

transceiver automatically selects the tone squelch func-

tion when priority watch starts.

• When “SCt-EP” is selected for the scan resume condi-

tion, the priority watch pauses on a no-signal channel.

The pager functions can be used only when an optional

UT-49 is installed. This function uses DTMF codes for paging

and can be used as a “message pager” to inform you of a

caller’s identity even if you leave the transceiver temporarily

unattended.

Personal calls and group calls are available with the pager

function. Personal calls use the receiving parties’ ID code for

calling. The receiving parties’ display shows your ID code and

other stations in the party know that you called.

Group calls use the group code for calling. All station displays

show the group code and all stations know that someone in

your group called.

To use the pager function in your group, all stations need the

Attach the EX-1759 to a suitable location for receiving in-

frared signals, e.g. sunvisor, etc.

• When using the connector for a microphone charger

Attach the EX-1759 to a suitable location for receiving in-

frared signals and where it can be connected to a cable, e.g.

the console, etc.

NOTE: DO NOT attach the EX-1759 where it will be sub-

ject to direct sunlight as it cannot detect infrared signals

under such conditions.

(When using BC-96

with external DC)

(When using the mic

connector for mic

charging.)

The installation clip can be oriented in 1 of 4 ways.

EX-1759

• Optional infrared sub receiver

An optional EX-1513

INFRARED SUB RECEIVER

is available to

increase the remote control reliablility and extend the control-

lable area. Connect the EX-1513 to the inside connector of

the EX-1759.
