How to mute the target alarm
A target in the target alarm zone produces both visual (flashing) and audible (beep)
alarms. To silence the audio alarm select the appropriate target alarm box then left-
click. The target alarm box indication shows "MUTE". This will deactivate the audio
alarm but will not stop the flashing of the offending target. You can also stop the alarm
by deactivating the target alarm zone (see section 1.39.3).
To reactivate the audio alarm, select the target alarm box then left-click to show
"WORK" in the box.

How to deactivate a target alarm
Select the target box to be deactivated, then press and hold the
left button
on the

Note:
When both alarm zones are active, the second ([2:]) alarm zone must be deac-
tivated before the first ([1:]) can be deactivated.
If both zones are active when you try to deactivate zone [1:], the system releases two
audible beeps and shows the message "DELETE ALR2 FIRST".
