Emergency Call
Initiating an Emergency Call
Press the
Emergency
key and you can initiate an emergency call to the predefined contact. Any
individual contact, group contact, default group, PSTN or PABX contact can be predefined as the
emergency contact.
There are two levels for emergency call: emergency priority and pre-emptive priority 3, which can be
programmed by your dealer. The emergency priority is endowed with the higher privilege; thus a call with
such priority can break any other call with pre-emptive priority 3, as well as calls with lower priorities.
Answering an Emergency Call
The emergency call is always received automatically. During an emergency call, the calling party can
talk with no need to use any key. If another member needs to talk, he/she should hold down
PTT
only
after the talking party stops talking and releases its
PTT
.
Hanging up an Emergency Call
See the corresponding part of “Individual call” or “Group call” in accordance with the call type of the
predefined contact.
