Radar Display Modes

The Radar screen has four standard operating modes. Each mode is available for use only with a compatible

radar.
Cruising mode—shows a full-screen image of the gathered radar information.
Harbor mode—intended for use in inland waters, this mode works best with short-range radar signals (2

nm or less).

offshore mode—intended for use in open waters, this mode works best with long-range radar signals.
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 Sentry mode, which

identifies a safe zone around your boat.

disables all guard zones.
