MDC 1200 OPERATION

■ MDC 1200 system operation

The MDC 1200 signaling system enhances your transceiver's
capabilities. It allows PTT ID*, Selective Calling, Call Alert,
Radio Check, Messaging and Emergency signaling. Also,
the dispatcher can stun and revive transceivers on the sys-
tem.
An additional feature of MDC 1200 found in Icom transceiv-
ers 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.
The following section describes the operation of the MDC
1200 features using the alias function. The Selective Call,
Call Alert and Radio Check features can also be used with
direct ID code entry from the transceiver keypad. (p. 32)
Please note that your dealer has set one of the programma-
ble keys (P0, P1, P2, or P3) for MDC 1200 operation.
*When [PTT] is pushed or released, self ID is transmitted.
