Icom IC-F6021 [17/24] Mdc 1200 system operation

■ 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.

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.
