Troubleshooting
2. If the receiver does not power up, check the power source.
The receiver supports both internal (battery) and external
power sources.
If using the internal power source, make sure the internal
battery has been fully charged before it was inserted in the
receiver. A too low battery will prevent the receiver from
powering up.
If using external power, check to ensure the power cable
is properly connected to both the external battery and the
receiver.
• If the cable is properly connected, check the power
level of the external power source. If low, replace the
battery with a charged battery and turn on the receiver.
• If the external power source is good and the cable is
connected to both the receiver and the power source,
there may be a problem with the cable. If available, try
a different power cable. If the new cable works, the old
cable is malfunctioning. Call your local dealer or email
Ashtech technical support to have the cable repaired.
3. If the receiver is now powered up, go to step 2.
Step 2. Does the
Number of Tracked
Satellites Stay
Abnormally Low?
1. Check the information displayed on the receiver front
panel. In the upper line, starting from the left, the first
number displayed should gradually rise from 0 to 8 or
more. This information represents the number of tracked
satellites. In the same time, the last number in the same
line should increase as well, in the same proportion. This
information represents the number of satellites actually
used by the receiver, and should be equal to, or slightly
less than, the first number in the line.
2. If the receiver fails to track any satellites after a few
minutes of operation, see if you can improve this by
moving the receiver to a better place (a more open-sky
area) where there can’t be any doubt on the possibility for
a receiver to track satellites.
3. If the receiver still fails to track any satellites, a
component may be malfunctioning. Call your local dealer
or email Ashtech technical support for assistance.
