Sentry Mode
Sentry mode allows you to put the radar into timed-transmit mode, in which you can configure a radar transmit
and standby cycle to conserve power. You can also enable a guard zone in this mode, which identifies a safe
zone around your boat and sounds an alarm when a radar object enters this zone. Sentry mode works with all
Garmin GMR model radars.
