Using Cruising Mode
Cruising mode is the standard radar operation. If you switch from Sentry mode (see Using Sentry
Mode) to Cruising mode, the antenna will go into full-time transmission and will disable any guard
zones.
To enable Cruising mode, touch Radar > Cruising.
Use the Cruising screen to view a full-screen image of the gathered radar information. Your position
is in the center of the screen, and the rings provide distance measurements.

The zoom scale represents the distance from your position (the center) to the outermost ring. Each
ring represents an even division of the zoom scale. For example, if the zoom scale is set at three
miles, each ring represents one mile from the center out. Adjust the zoom scale using the and
buttons.
Using Sentry Mode
NOTE: When Sentry mode is enabled, all MARPA targets are cancelled, and you cannot acquire
MARPA targets until you exit Sentry mode.
Sentry mode allows you to put the radar antenna into timed-transmit mode, in which you can
congure a transmit and standby cycle. You can also enable a guard zone in Sentry mode, which
identies a safe zone around your boat. An alarm sounds when a radar object enters this zone.
To enable Sentry mode, touch Radar > Sentry.

From the Home screen, touch Radar > Sentry > Menu > Sentry Setup > Timed Xmit.
To set the standby and transmit times:
1. From the Radar screen, touch Menu > Sentry Setup.
2. Touch Timed Xmit if it is set to off, and then select Stdby Time or Xmit Time.
3. Enter the time in minutes using the on-screen keyboard and then touch Done.
