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
receiver to frequently lose and reacquire its lock on a WAAS satellite.
That can result in the alarm repeatedly going on and off. You have the
option of turning off the WAAS Acquired/Lost alarm without affecting
how the unit uses WAAS. Here's how:
1. Press MENU|MENU|

2. With the option highlighted, press ENT to uncheck it (turn off) or
check it (turn on). After the option is set, press EXIT|EXIT to return to
the page display.
3. You can return to this command and press ENT again to turn the
feature on.
