6.4  Notification calls 
While the phone is making such a call, the standard call processing message appears on the display and 
you are unable to receive or set up any other calls. 
Notification calls have the highest priority over any other calls. In the event of a notification call, any other 
call will be interrupted. All keys will be locked during the notification process in order to avoid the activation 
of call back, consultation call, etc. 
6.5  Alarm acknowledgment  
After an alarm is triggered, the alarm server can set a location audio signal on the phone. This signal is 
designed to help rescue teams to locate the phone and its user. 
The phone sends a location audio signal. 
If the on-screen acknowledgment is configured you can directly acknowledge by pressing on the 
acknowledgment softkey when the 'Send Acknowledge' pop-up is displayed. 
 
Depending on the configuration of the phone, you can use P1 or P2 keys to send acknowledgment (see 
chapter: Configure the P1, P2 keys).
