1.38.2 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 press
the left button. The target alarm box indication shows "ALRu MUTE". This will deac-
tivate 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 1.38.3).
To reactivate the audio alarm, select the target alarm box then press the left button
until the target alarm box shows "ALRu WORK".
1.38.3 How to deactivate a target alarm
Select the target box to be deactivated, then press and hold the left button.
Note: When both [ALR1] and [ALR2] are active, [ALR2] must be deactivated before
[ALR1] can be deactivated.
If [ALR1] and [ALR2] are active when you try to deactivate [ALR1], the system releas-
es two audible beeps and shows the message "DELETE ALR2 FIRST".
