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.

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.

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;

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

■ Repeater search scan
The repeater search scan is not only searching for a signal

Thus the repeater search scan function searches an available
repeater in the area even if the repeater is not in use.
IMPORTANT!:
A microphone should be on hook to start scanning.
The repeater search scan detects a signal on the repeater
output, CH 1 to 8, only. Therefore, repeater availability cannot be guaranteed even the repeater scan is stopped,
because the scan will stop if any activity is detected. (The
scan is cancelled when receiving a signal, such as stations
communicating in simplex operation on a repeater output
channel.)

(CTCSS)
D Setting the CTCSS frequency
The IC-400PRO is equipped with 51 CTCSS frequencies for
group mode operation. The group mode operation provides
communication with silent stand-by since you will only receive
calls from group members using the same CTCSS frequency.
First of all, set the same CTCSS frequency for all group member’s transceivers.
To access the IC-40Jr or IC-4088S operating in Group mode
(including Smart-Ring function), the same CTCSS frequency
should be set. Select the CTCSS frequency matching the
group code that is set to the IC-40Jr or IC-4088S, referring to
the “Group code/frequency table” in the next page.
For example, when group code “01” is set to the IC-40Jr/IC4088S, select “67.0” as CTCSS frequency.
NOTE: Only the stations with the same CTCSS frequency
or matching the group code can be heard in group mode
operation.
To turn ON the group mode operation:
q Push []/[]to select the desired channel.
w While in Function mode, push [O]

Group code/frequency table(unit: Hz)
✔ What is CTCSS (Continuous Tone Coded Squelch
System) GROUP MODE ?
CTCSS (Continuous Tone Coded Squelch System)
GROUP MODE allows communication with silent stand by.
Only signals containing a specific CTCSS frequency can
open the squelch.
This conveniently eliminates unwanted audio and is useful
in group activities or security related activities where
unwanted output can be a problem. Note that CTCSS
group mode is not private—anyone can receive your calls.
The IC-400PRO is equipped with 51 CTCSS frequency for
CTCSS GROUP MODE use. Selecting a CTCSS frequency applies it to all 40 operating channels. To temporarily
hear all signals (including noise) push and hold [MONI]. Do
not use CTCSS GROUP MODE if you want to hear signals
on all channels.
: Stands for the recommended CTCSS frequency. In
case a frequency other than at left is used, sometimes
the squelch system may not performed correctly.

SELCALL OPERATION
■ General
In addition to the group mode operation for silent stand-by,
the SelCall operation is available. SelCall is an abbreviation
for “Selective Calling”. In Group mode operation, there are 51
ways to make an individual call with CTCSS frequencies versus 100,000 ways to make an individual call with Selcall using
5tone.
SelCall allows you to selectively call another unit that is operating on the same channel.
SelCall can also call the entire group on that channel using
group call code.
The caller station code/name, status message, Answer Back
function, automatic scan start function, etc. are available with
SelCall operation. A variety of functions are available depending on the setting with the CS-400PRO
See the help file for setting details.
