Mode —
The Mode selections are ‘Normal’, ‘Battery Saver’ and ‘Simulator’.
‘Normal’ —
This is the default mode set from the factory. Use this setting
for best performance.
‘Battery Saver’ —
When ‘Battery Saver’ is selected, the receiver is optimized to
save battery power. When in the Battery Saver mode you may experience
slower screen updates, but should notice a signifi cant increase in battery
life. While in Battery Saver mode, the unit will not receive WAAS satellite
signals.
‘Simulator’ —
When in ‘Simulator’ mode the GPS receiver is turned off and
the unit simulates satellite reception. Use the Simulator mode when the
unit is indoors and you wish to practice with the unit.
WAAS’ —
WAAS is an acronym for “Wide Area Augmentation System”. You
can use the WAAS capability of the GPS 76 to increase the accuracy to
approximately 3 meters. When enabled the GPS receiver searches for a WAAS
satellite, then receives data that will help correct differentials in the GPS
signal. When the unit is using WAAS data, a “D” will be displayed in the
Satellite Strength Indicators on the GPS Information Page, and the receiver
status will indicate a 2D or 3D Differential Location.
Currently the WAAS system is not fully operational and there are only two
satellites in place, one over the Pacifi c Ocean and one over the Atlantic Ocean.
You must have a clear unobstructed view of the sky for the GPS 76 to be
able to receive a WAAS signal, even then, at times it may not be possible to
receive a WAAS signal.
For more information on the WAAS system visit the Federal Aviation Adminis-
tration website at (gps.faa.gov).
