Selecting Displayed Items on the Map Page
The rest of the map setup page lets you specify what
items are displayed or plotted on the map page. The first
four plot items may be turned on or off by selecting ‘yes’ or
‘no’ in the appropriate field:
• The ‘rings’ selection will display the three present
position range rings on the map.
• The ‘route’ selection will plot the straight leg lines
between waypoints of an active route and display all
route waypoint names.
• The ‘nearest’ selection will display the nine nearest
waypoints to your present position (not to the target
cursor on the map).
• The ‘names’ selection will display the waypoint name
for the nine nearest waypoints.
To turn a plotted item on or off:
1. Highlight the confirmation (Yes or No) field for the plotted
item and press

.
2. Use
U
and
D
to select ‘yes’ or ‘no’, and press

Track Log Display
The track log option sets the number of points the unit
will attempt to display on the map page. The default setting
of 250 points provides good resolution with minimal screen
clutter. The maximum setting is 768 points. Once you’ve
reached the maximum number of track points, the older
points will be lost as new points are added. Note that
adjusting the track points displayed will not affect whether
or not the receiver records a track log or the ability to cre-
ate a TracBack route.
To enter a log setting:
1. Highlight to the ‘track log’ field and press
E
.
2. Enter a value in the 3-digit field and press
E
. If you do
not want to display a track, enter ‘000’.
Track Log Setup Page
The track log setup page lets you manage the GPS 40’s
tracking data. From this page, you can select whether or
not to record a track and define how it is recorded.
