Troubleshooting
Receiver will not turn on:
1. Check to see if batteries are installed correctly.
2. Replace with two new AA alkaline batteries.
Takes more than 10 minutes to get a position fix:
1. If there are any obstacles nearby or overhead, move to a new location.
2. Make sure that the antenna is pointing up, has a clear view of the sky and
is a reasonable distance away from your body.
3. Check Satellite Status screen to see where the satellites are and if the
receiver is acquiring data.
4. If the receiver still does not get a position fix within 10 minutes, you may
wish to repeat the initialization procedure.
Receiver turns off unexpectedly
This is commonly is caused by excessive static electricity. Turn the receiver
back on and it should operate normally. Move the receiver to a new
location to avoid a similar occurrence.
Battery life seems shorter than it should be:
1. Make sure that you are using two AA alkaline batteries.
2. Shorter life span of the batteries can be due to excessive use of the
backlight. Tu rn the backlight off when not needed.
Position coordinates on your receiver do not match the location on your
map.
1. Make sure that your receiver is set up to use the same datum as your map.
The map datum is generally shown in the map legend. See Setup -
Changing the Map Datum under Reference for instructions on selecting the
map datum in your receiver.
2. Check your LAT/LON format. Make sure that the format selected in
COORDINATE SYSTEM (DEG/MIN/SEC or DEG/MIN.MM) is in
the same format as the map you are using.
Position on map is not exactly on the road.
It could be caused by distance shifts to the map.
Use map data for reference and do not rely completely on it.
Data was not saved or was corrupted.
This can be caused because you removed the batteries or removed external
power with the SporTrak turned on.
