PRECAUTION
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 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.
i
DO NOT push the PTT when not actually desiring to transmit.
DO NOT use or place the transceiver in areas with temperatures 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 vehicle’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 environments.
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.

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

3 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.

■ 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).
qPush []/[] to select the desired channel from 1 to 8 (repeater output channel).
wPush [DUP] (Dup/Pri) to set duplex.
•“ ” appears.
•The duplex setting is only available on channels 1 to 8.
eWhile pushing and holding [PTT], speak into the microphone 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).

■ Scan types
The transceiver has 4 scan types, tag function and 4 resume conditions providing scanning versatility.
Tag channels are independently set for open, group and priority scans. Initially, all channels may be set as tag channels for all scans.

4 SCAN OPERATION
■ 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.
DSetting scan tag
q Select the desired channel. (p. 5)
wPush [SCN] (Scan Start/Stop) for 1 sec. to enter the scan type selection mode.
Push [SCN] for 1 sec.
Previously selected scan type is displayed.
ePush []/[] to select the desired scan type.
• Open, group, priority and repeater search scans are available.
Push [] or []

tPush [SCN] (Scan Start/Stop) for 1 sec. to return to Normal mode.
Open scan setting
To speed up scanning:
For open scan, cancel the tag channel setting to skip undesired channels such as usually busy channels.
For group scan, set only often-used channels as tag channels.
All memory channels may be set as tag channels by default.
