MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiv-
er’s capabilities. It allows PTT ID, Selective Calling (SelCall),
Call Alert, Radio Check, Stun, Revive, Status, Messaging and
Emergency signaling.
An additional feature of the MDC 1200 system found in Icom
transceivers is called aliasing. Each transceiver on the system
has a unique ID number. Aliasing substitutes the ID number
with an alphanumeric name. For transmit, you can use this
alias to select a transceiver to call. For receive, the alias of
the calling station is displayed instead of the ID.
Please confirm that your dealer has set one of the program-
mable keys (

[P1]
,
[P2]

[P3]

MDC 1200 system operation.
NOTE:
During MDC 1200 system operation, BIIS 1200
system and IDAS operations are disabled.
