Important Information
An Emergency Group Call is configured as non-tactical or
tactical:
• A non-tactical call initiates on a talkgroup designated by
your Service Provider. The group might be different than
the one displayed on the terminal screen when starting the
call. After exiting from non-tactical emergency mode the
terminal will be attached to the group that was selected
before initiating the non-tactical call. When in non-tactical
emergency mode, you will not be able to switch talkgroups.
• The required time you need to press the Emergency button is set
by default to 0.5 seconds. The time can be configured by your
Service Provider.
• Pressing the Emergency button even if Transmit Inhibit is
activated causes immediately the MTP850 to transmit. When
entering Emergency Operation the MTP850 should not be within
the RF sensitive area any longer!
• The MTP850 interrupts the AL call when you press the
Emergency button.
• For call alert, see settings in the Vibrate menu option (page 90)
and the Tones menu option (page 93)
