Show WAAS Alarm
When the signal is available, your unit will automatically use WAAS to
boost the accuracy of a position fix. When the WAAS signal is lost or
acquired, a message appears. Since the U.S. government is still devel-
oping the WAAS system, it is 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 off. If you want, turn off the WAAS
Acquired/Lost alarm without affecting how the unit uses WAAS.
