Motorola XPR 7350 ユーザーズマニュアル

You can turn on or off the ringing tones for a received Private 
Call (see Turning Radio Tones/Alerts On or Off on page 37). 

Your radio can be programmed by your dealer to continually 
alert you when a radio call remains unanswered. This is done 
by automatically increasing the alarm tone volume over time. 

This feature is known as Escalert.

Call Alert paging enables you to alert a specific radio user to call 
you back when they are able to do so. This feature is accessible 
via a programmed One Touch Access button.

Procedure:
When you receive a Call Alert page:

You hear a repetitive tone. The LED blinks yellow.

Press the PTT button within four (4) seconds of receiving a 
Call Alert page to respond to the Private Call.

Press the programmed One Touch Access button to make 
a Call Alert to the predefined ID.

The LED lights up solid green when your radio is sending 
the Call Alert.

If the Call Alert acknowledgement is received, two chirps 
sound.
OR
If the Call Alert acknowledgement is not received, a 
low-pitched tone sounds.
