To turn a map item on or off:
1. Highlight the ‘confirmation’ (‘YES’ or ‘NO’) field for the map item, and press ENTER.
2. Select ‘YES’ or ‘NO’, and press ENTER.
Track Setup Page
The track setup page lets you manage the GPS II’s track log data. From this page,
you can select whether to record a track log and define how it is recorded.
To turn the track log on or off:
1. Highlight the ‘TRACK LOG” field, and press ENTER.
2. Select ‘YES’ or ‘NO’, and press ENTER. (Note: Turning the track recording off will dis-
able the tracback feature.)REFERENCE
O n - s c reen  range  rings  help
you estimate distances relative
to your present position. The
value of each ring is deter-
mined  by  the  current  zoom
scale. The distance value of
each ring is equal to 1/5 of the
current zoom range, with the
i n t e rval  of  each  ring  noted
below the first range ring.GPS II  7/23/98 4:05 PM  Page 66 
						

							67Track Method
The stored track method determines how often positions are stored in the track
log. The default setting is automatic, which will store a track based on resolution.
This setting gives you the most efficient use of track memory and provides the most
accurate TracBack route.
To change the method to record points based on a specific time interval:
1. Highlight the ‘method’ field, and press ENTER.
2. Select ‘TIME INTERVAL’ (Fig. 67a), and press ENTER twice (Fig. 67b).
3. Enter a value in hours, minutes, and seconds, and press ENTER.
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 the
receiver records a track log or the ability to create a TracBack route.

							68Managing and Clearing the Track Log
The rest of the track setup window displays the percentage of available memory
currently used to store track log data and function fields to clear the track log mem-
ory and activate the backtrack feature.
To clear the track log:
1. Highlight ‘CLEAR LOG?’ (Fig. 68), and press ENTER.
2. Highlight ‘Yes’, and press ENTER.REFERENCE
It’s a good idea to clear the
track log at the end of the trail
head, etc., in order to make the
best use of the tracback fea-
ture.

							69Menu Page
The GPS II’s menu page provides access to additional pages (submenus) that are
used to select and customize operation and navigation setup. These eight pages are
divided into categories by function. The waypoint and route management pages are
discussed in their own respective sections. We’ll now address the rest of these pages
in the order they appear on the menu page.
To select a submenu page from the menu page:
1. Highlight the page (Fig. 69a), and press ENTER (Fig. 69b).
2. To return to the menu page, press QUIT.

							70Distance and Sun Calculation
The distance and sun calculation submenu page will give you the distance and
bearing between any two waypoints or between your present position and a way-
point. It will also calculate the sunrise and sunset (in local time) for a particular date
at either your present position or any stored waypoint.
To perform a distance and sun calculation:
1. Highlight the ‘from’ field, enter the desired waypoint (Fig. 70a), and press ENTER.
2. Highlight the ‘to’ field, enter the destination waypoint, and press ENTER.
3. The ‘date’ field will become highlighted (Fig. 70b). Enter the date you’ll arrive at your
destination, and press ENTER.
If you haven’t marked your present position as a waypoint or you leave the ‘to’
field blank (Fig.70b), the sunrise and sunset at your present position will be provid-
ed.

							71System Setup
The system setup submenu page (Fig. 71a) is used to select the operating mode,
time offset, and screen preferences. The GPS II has three operating modes:
•Normal Modeoperates the unit at maximum performance, and provides a
battery of life up to 12 hours on alkaline batteries.
•Battery Saver Mode(Fig. 71b) is suitable for most applications, and extends
battery life to up to 20 hours on alkaline batteries by reducing the receiver’s
update rate when navigational conditions permit (e.g., you’re traveling a steady
course without significant variations in speed or heading). Since battery saver
mode changes the update rate based solely on navigational conditions, the bat-
tery life will vary accordingly.
•Simulator Modeallows you to operate the unit without acquiring satellites,
and is ideal for practicing or entering waypoints and routes while at home.
To select an operating mode:
1. Highlight the ‘mode’ field, and press ENTER.
2. Select a mode, and press ENTER.

							72Date and Time Setup
The date and time is located directly below the mode field. Note: Date and time
information is derived from the GPS satellites and cannot be changed by the user.
Because the time shown is UTC (Greenwich mean time) time, you will need to enter
a time offset to display the correct local time for your area. To determine the time
offset for your area, note your position and refer to the chart in Appendix F.
To enter the time offset:
1. Highlight the ‘offset’ field (Fig. 72a), and press ENTER.
2. Enter the time offset, and press ENTER. 
Time Format
The time display shown on the system setup and position pages may be set to
display the time in a 12- or 24-hour format.
To select the time format:
1. Highlight the ‘hours’ field (Fig. 72b), and press ENTER.
2. Select 12- or 24-hour display, and press ENTER.
