PRECAUTION

READ ALL INSTRUCTIONS carefully and com-

pletely before using the transceiver.

SAVE THIS INSTRUCTION MANUAL — This

instruction manual contains important operating instructions
for the IC-400PRO UHF TRANSCEIVER.

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

NOTE

Personal injury, fire hazard or electric shock
may occur.

Equipment damage may occur.

If disregarded, inconvenience only. No risk
of personal injury, fire or electric shock.

than 16 V DC. This will damage 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 allow children to play with any radio equipment

containing a transmitter.

NEVER expose the transceiver to rain, snow or any liquids.

The transceiver may be damaged.

NEVER operate or touch the transceiver with wet hands.

This may result in an electric shock or damage the transceiv­er.

DO NOT push the PTT when not actually desiring to trans-

mit.

DO NOT use or place the transceiver in areas with tem-

peratures below –10°C or above +60°C, or in areas subject to
direct sunlight, such as the dashboard.

AVOID operating the transceiver without running the vehi-

cle’s engine. When the transceiver’s power is ON and your
vehicle’s engine is OFF, the vehicle’s battery will soon
become exhausted.

AVOID placing the transceiver in excessively dusty envi-

ronments.

AVOID placing the transceiver against walls. This will

obstruct heat dissipation.

AVOID setting the transceiver in a place without adequate

ventilation. Heat dissipation may be affected, and the trans­ceiver may be damaged.

AVOID the use of chemical agents such as benzine or

alcohol when cleaning, as they damage the transceiver sur­faces.

USE the specified microphone only (supplied or optional).

Other microphones have different pin assignments and may
damage the transceiver.

BE CAREFUL! The transceiver will become hot when

operating continuously for long periods.

This device complies with Standard
Australia Specification No. AS/NZS4365­1996 and AS4295-1995.

D Transmitting notes

• Time-out timer

After continuous transmission for a pre-programmed period,
the time-out timer is activated causing the transceiver to stop
transmitting and automatically select receive.

TRANSMITTING:

q While pushing and holding [PTT], speak into the micro-

phone at your normal voice level.

w Release [PTT] to receive.

IMPORTANT!: To maximize the readability of your signal;

➥ After pushing [PTT], pause briefly.
➥ Hold the microphone 2 to 5 cm from your mouth, then

speak into the microphone at a normal voice level.

NOTE: Transmission is inhibited when the channel is in 5
tone mute condition (‘Inaudible’ condition), or receive only
channel is selected.

REPEATER OPERATION

■ Repeater operation

Repeaters allow you to extend the operational range of your
radio.

Normally, a repeater has independent frequencies for receive
and transmit.

Repeater example;

Receives the channel 31 signal and
the detected audio signals are trans­mitted on channel 1 simultaneously.

Ch 1 Ch 31

Ch 31 Ch 1

Station A:
Tx: Channel 31
Rx: Channel 1

Station B:
Tx: Channel 31
Rx: Channel 1

■ Accessing a repeater

A repeater amplifies received signals and re-transmits them
on a different channel, allowing you to communicate over
greater distances with improved reliability. When using a
repeater, the transmit channel is shifted from the receive
channel by 30 channels. You can search the accessible
repeater in your local area using the Repeater search scan
function (p. 13).

q Push []/[]to select the desired channel from 1 to 8

(repeater output channel).

w Push [DUP] (Dup/Pri) to set duplex.

• “” appears.

• The duplex setting is only available on channels 1 to 8.

e While pushing and holding [PTT], speak into the micro-

phone at your normal voice level.

• The displayed channel automatically changes to the transmit
channel (repeater input channel), and “” appears.

r Release [PTT] to receive.
t To cancel the duplex setting, push [DUP] (Dup/Pri).

■ Scanning preparation

IC-400PRO scans all tagged channels, and can be selected
so the scan resume condition is a pause or timer scan.
Therefore, these items must be set before starting a scan
(except the repeater search scan). These items must be set
for each scan type (open, group and priority) independently.

All memory channels may be set as tag channels by
default.
