MDC 1200 OPERATION
■
MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s
capabilities. It allows PTT ID, Selective Calling, CallAlert,
Radio Check, Stun, Revive, Status, Messaging and
Emergency signaling. Also, the dispatcher can stun and
revive transceivers on the system.
An additional feature of MDC 1200 found in Icom transceivers
is called aliasing. Each transceiver on the system has a
unique ID number. Aliasing allows the substitution of an
alphanumeric name for this ID number. 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 note that your dealer has set one of the programma-
ble keys (IC-F70 series:
