Using Geocaching Mode
The GM-120 features a geocaching function which enables users to use
location coordinates and set up caches to participate in treasure hunting
games.
Setting Geocaching Coordinates
To set up the cache box from the Geocaching menu:
1. In Geocaching mode, press the Menu button to
display the menu options.
2. Select Check Box Information and press OK to
display the Treasure Box List.
3. Select a box to set up the location coordinates.
You can set up to 3 cache boxes on the GM-120.
4. Use the navigation keys to highlight the field you
want to change such as name, comment,
coordinates, and radius.
5. Check the Alert box to enable an alert to be
displayed when the cache is reached.
6. Highlight the √ option and press OK to save
changes. The cache box you just set up is shown
on the map page.
Repeat steps 1 to 6 to set up other cache boxes.
You can also set up cache boxes directly from the map
page:
1. Move the cursor to the location where you want to
set up a cache box.
2. Hold the OK button to save the current location.
The cache box that has not been alerted by user
will be used for saving automatically. If all three
cache boxes have been set up, the device will
save data to Box 3 and replace the current data.
