Radar 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).
Page 60
Radar Harbor Mode Harbor mode is the standard radar operation for use in inland waters, with a GMR 604 xHD, 606 xHD, 1204 xHD, or 1206 xHD radar. Harbor mode works best with short-range radar signals (2 nm or less). NoTe: If you switch from Sentry mode to Harbor mode, the radar switches to full-time transmission and disables all guard zones.
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. Showing Sentry Mode From the Home screen, select Radar >...
