GPS Training - Garmin Etrex
SETUP
This is also where you
can check the battery
status
This is where you set up the unit. Here you can choose
which position format to use eg degrees.decimal degrees or
degrees minutes seconds etc.; the units to use eg statute
miles / nautical miles / metric; local timezone; display con-
trast; interface and system. You can easily swap between
settings eg a waypoint recorded in ddd.ddddd can also be
shown in ddd.mm.ss,etc.
The Darwin Project in Tristan
uses GMT timezone, WGS84
map projection, ddd.ddddd
position format (not really the
most
convenient
required for a software pack-
age we use called MAPINFO)
and
True
North.
'Interface' is set to 'GARMIN'
(required for computer con-
nection) and the 'System' set-
ting is set to 'Battery Save'
which seems to put the unit on
hold when its not moving thus
saving the batteries. Whether
you use miles or Km is a mat-
ter of personal preference.
The DISPLAY screen
lets you adjust the
screen contrast and
set how long the light
will stay on after the
