System Page - Overview
The System Setup Page allows you to select from four
modes of operation ‘Normal’, ‘Battery Saver’, ‘Use With GPS
Off’, and ‘Demo Mode’.
Of these, the ‘Battery Saver’, ‘Use With GPS Off’, and
‘Demo Mode’ options signifi cantly save battery power. The
‘Battery Saver’ mode reduces the rate of satellite position
updating and the ‘Use With GPS Off’ option stops satellite
signal reception. The ‘Demo Mode’ simulates navigation.
This Page Option Menu also displays the current version
of unit operating software and the Internal Unit i.d.
Number. The path for downloading software updates from
the GARMIN website is (www.garmin.com). Downloading
requires use of the GARMIN PC Interface Cable. Instruc-
tions for downloading are posted at the website.
You can use the Wide Area Augmentation System (WAAS)
capability of the eTrex Mariner to produce a more accurate
position fi x (3 meters nominal). When enabled (the GPS mode
must be set to ‘Normal’ and the interface set to other than
RTCM mode), this feature searches for a WAAS satellite near
your location and then receives data for correcting differentials
in the GPS satellite signals. When WAAS has been enabled,
you will see WAAS satellite numbers, beginning at No. 33
or above, displayed on the Satellite Page. When differential
correction data has been received for GPS satellites (numbers
32 or below), a ‘D’ will appear in the signal bar beneath the
skyview. It is helpful to orient the unit antenna toward the
WAAS satellite shown in the skyview. To learn more about
the WAAS System, its satellite positions and current state of
development, access the Federal Aviation Administration web-
site (http.//gps.faa.gov/). Refer to the Troubleshooting Guide on
page 57 if WAAS access and differentials are not obtained.
You can select from a list to change the display language.
