BASIC OPERATION
■
MDC 1200 system operation
The MDC 1200 signaling system enhances your transceiver’s capa-
bilities. It allows PTT ID* and Emergency signaling.
* When [PTT] is pushed and/or released, the transceiver transmits your
station ID.
D
Transmitting an Emergency Call
The MDC 1200 system’s Emergency feature can be accessed
using the [Emergency] key. The transceiver will send an Emergency
MDC 1200 system command once, or repeatedly for a programmed
number of times until it receives an acknowledgement signal.
The emergency call can be transmitted without a beep sound, de-
pending on how the emergency function is programmed. Ask your
dealer for details.
■
Lone Worker Emergency Call
When the Lone Worker function is turned ON, and no operation is
performed for the specified time period*, the transceiver enters the
emergency mode, and then the countdown for the emergency call
transmission starts.
After the specified time period* has passed, an emergency call is
automatically transmitted once, or repeatedly*.
If someone operates the transceiver before the call is transmitted, the
transceiver exits the emergency mode, and the emergency call is can-
celled.
* Depending on the presetting. Ask your dealer for details.
