Show WAAS Alarm

When the signal is available, your unit will automatically use WAAS to
boost the accuracy of the position fix. When the WAAS signal is lost or
acquired, an alarm message appears. Since the U.S. government is still
developing the WAAS system, it's not unusual for a GPS/WAAS re-
ceiver to frequently lose and reacquire its lock on a WAAS satellite.
That can result in the alarm repeatedly going on and off. If you want,
you have the option of turning off the WAAS Acquired/Lost alarm with-
out affecting how the unit uses WAAS. Here's how:
1. Press
MENU
2. With the option highlighted, press
check it (turn on). After the option is set, press
the page display.
3. You can return to this command and press
ture on.

Software Version Information
