MDC 1200 SYSTEM OPERATION
Section
3
The MDC 1200 signaling system enhances your trans-
ceiver’s capabilities. You can receive or transmit a PTT
ID. PTT ID is a calling station ID that is sent by pushing
or releasing
[PTT]
.
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 give an al-
phanumeric name for each station ID. In transmit, you
can use this alias to select a transceiver to call. In re-
ceive, the alias of the calling station is displayed in-
stead of the ID.
NOTE:
To use the MDC 1200 system, set the related set-
tings by using the CS-G88
programming
software
(
purchase separately
).
The factory default is not set to allow the system op-
eration.
