Silencing the audible alarm
Any radar targets violating the guard zone will
trigger the audible alarm. You can silence the
audible alarm by pressing the [GUARD
ALARM] key. When this is done, “G(ACKN)”
replaces “G(IN).” This means the alarm is ac-
knowledged. Press the key again to reactivate
the alarm.
Cancelling the guard zone and alarm
Press and hold down the [GUARD ALARM]
key until the guard zone disappears.
