Reference
‘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.
‘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 GPSMAP 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 GPSMAP 76 to
be able to receive a WAAS signal, even then, at times it may not be possible
to receive a WAAS signal. WASS satellites are not received in Battery Saver
Mode.
For more information on the WAAS system visit the Federal Aviation Adminis-
tration website at (gps.faa.gov).
‘Backlight Timeout’ —
Sets the time that the Backlight will remain on once
activated. The options are ‘Stays On’, ‘15 Seconds’, ‘30 Seconds’, ‘1 Minute’
and ‘2 Minutes’.
‘Beeper’ —

‘Key and Message’, ‘Message Only’, and ‘Off’.
