IMPORTANT: It is recommended that the dealer sets
an Emergency channel in each zone, to provide a
reliable Emergency call operation.
NOTE: Depending on the presetting, the following
functions may be automatically activated.
Auto TX function
After an Emergency call transmission, the
transceiver transmits the microphone audio for a
preset period of time.
Auto RX function
After an Emergency call transmission, the
transceiver stands by in the Audible mode for a
preset period of time.
When the transceiver enters the Emergency mode, a
countdown starts. The transceiver counts down during
the Reminder Timer set time.
Before the Reminder Timer set time expires, the
transceiver transmits an Emergency call once, or
repeatedly*, on the specied Emergency channel.
If no Emergency channel is specied, the Emergency
call is made on the previously selected channel.
* Depending on the presetting.
L The transceiver automatically transmits a
repeat Emergency call until it receives an
acknowledgement, or until a user turns OFF the
transceiver.
L If the transceiver is set for Silent operation, it
transmits an Emergency call without a beep
sounding or the status indicator lighting.
