GROUP MODE OPERATION
5
To cancel the group mode operation:
q
While in Function mode, push [ O ] (Bank/Func) for 1 sec.
to enter Set mode.
• Push [
O
] (Bank/Func) for 1 sec. to enter the transceiver into
Function mode.
w
Push [MONI] for 1 sec. to enter the individual setting.
e
Push [MONI] several times until “CT” appears.
r
Push [DUP] to select “OFF” (group mode OFF).
t
Push [MONI] for 1 sec. to exit the individual setting, then
push [ O ] for 1 sec. to exit Set mode.
• The under bar indicators disappear.

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 frequen-
cy 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.
