NorthStar Navigation EXPLORER 657 Alarms, Simulate mode, has user settable alarms see section

2-5 Alarms

When the 657 detects an alarm condition, it displays a warning message on the display, the internal beeper sounds and any external beepers or lights operate.

Press to clear the alarm. The alarm will sound again if the alarm condition occurs again.

The 657 has user settable alarms (see section 17-9).

2-6 Simulate mode

In Simulate mode, the 657 ignores data from the GPS antenna and other transducers and sensors and the 657 generates this data itself. Otherwise, the 657 functions normally.

There are two simulate modes:

•Normal: Allows a user to become familiar with the 657 off the water.

•Demo: Simulates a boat moving along a route and automatically displays different 657 functions.

To start and stop Simulate mode, and for more information, see section 17-15. In simulate mode, Simulate or Demo flashes at the bottom of the display.

! WARNING

Never have Simulate mode on when the 657 is navigating on the water.
