Mdc 1200 System Operation - Icom IC-F5020 Series Instruction Manual

■ MDC 1200 system operation

The MDC 1200 signaling system enhances your trans-
ceiver's capabilities. It allows PTT ID*, Emergency signaling,
and receiving Radio Check. Also, the dispatcher can stun
and revive transceivers on the system.
An additional feature of MDC 1200 system 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.
* When [PTT] is pushed and/or released, the transceiver transmits
your own station ID.
D Receiving an Emergency Call
q When an emergency call is received;
• Beeps sound.
• The calling station ID (or alias) and "EMG EMG" are displayed
alternately.
w Turn power OFF, change the channel, push [PTT] for re-
plying the call, etc. to stop the beep and display indication.
D Transmitting an Emergency Call
The MDC 1200 system Emergency feature can be accessed
using the [Emergency] key (p. 5). The transceiver will send
an Emergency MDC 1200 system command once or repeat-
edly for a programmed number of times until it receives the
acknowledgement signal.
The emergency call can be transmitted without a beep emis-
sion, and the LCD indication change depends on how emer-
gency is programmed. Ask your dealer for details.
D Receiving a Stun and Revive
The dispatcher can send MDC 1200 system signals that
will stun or revive your transceiver. If a Stun command is
received that matches your station ID, the transceiver will
display "SORRY" (default) and you can not receive or trans-
mit. When a Revive command is received that matches your
station ID, normal operation is restored.
