Mdc 1200 System Operation - Icom IC-F6020 Series Instruction Manual

■ MDC 1200 system operation

The MDC 1200 signaling system enhances your transceiver'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 OFF the transceiver, change the channel, push [PTT]
to reply to the call, and so on, 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 repeatedly for a programmed number of times until it
receives the acknowledgement signal.
The emergency call can be transmitted without a beep
emission, and the LCD indication change depends on how
emergency 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
transmit. When a Revive command is received that matches
your station ID, normal operation is restored.
