Note 1: To create a 360° alert zone, set Point B at the same location as Point A.
Note 2: Two alarm zones can be set simultaneously. The second alarm zone is only
available when the first alert zone is active, however.
Note 3: When the target alarm zone is not within the range in use the indication "UP
RNG" appears to the right of the target alarm box. In this case select a range that will

1.37.2 How to mute the target alert
A target in the target alert zone produces both visual (flashing) and audible (beep)
alarms. To silence the audio alarm select the appropriate target alert box then press
the
left button . The target alert box indication shows "ALR
u
MUTE". This will deacti-
vate the audio alarm but will not stop the flashing of the offending target. You can also
stop the alert by deactivating the target alert zone (see section 1.37.3).
To reactivate the audio alert, select the target alert box then press the left button until
the target alert box shows "ALR
u
WORK".
1.37.3 How to deactivate a target alert
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".
