Radar Display Modes - Garmin GPSMAP 700 Owner's Manual

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.
