MDC 1200 SYSTEM OPERATION
■
MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s
capabilities. You can receive or transmit PTT ID and Emer-
gency calls. You can also receive Radio Check, Stun, and
Revive calls.
An additional feature of the MDC 1200 system included in
Icom transceivers is called aliasing. Each transceiver on the
system has a unique ID number. Aliasing is a substitute for
this ID number and
you can set a ringer for each station ID.
When you receive a call from the specific transceiver, you
can distinguish it by its ringer type.
Please confirm that your dealer has set one of the program-
mable keys for MDC 1200 system operation. See page
4
for
more information about the programmable function keys.
