GROUP MODE OPERATION
■ Group mode
(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 mem-
ber’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/IC-
4088S, 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
]
(Bank/Func)
for 1 sec.
to enter Set mode.
• Push [
O
]
(Bank/Func)
for 1 sec. to enter the transceiver into
Function mode.
• The bank and channel can be selected after entering Set mode.
e Push [MONI] for 1 sec. to enter the individual setting.
r Push [MONI] several times until “CT” appears.
t Push []/[]to select the desired frequency.
• When “OFF” is displayed, push [DUP] to enables the tone fre-
quency selection, in advance.
y Push [MONI] for 1 sec. to exit the individual setting, then
push [
O
