Issue
Possible cause
Solution
The receiver does
not turn on.
External power is too
low.
Check the charge on the external battery and, if applicable,
check the fuse.
Internal power is too
low.
Check the charge on the internal battery.
External power is not
properly connected.
Check that the Lemo connector or 26-pin adaptor is seated
correctly, and that the cable is secured to the receiver.
Check for broken or bent pins in the connector.
Faulty power cable.
Check that you are using the correct cable for the
port/battery.
Check that the correct battery is connected to a particular
port.
The ports on the GPS receiver are optimized for use with
different types of battery. The 26-pin connector is optimized
for Trimble custom external batteries, and the Lemo port is
optimized for external 12 V batteries such as car, motorcycle,
or truck batteries. If the wrong type of battery is connected
to a port, it is likely that it will cut off earlier than normal.
Check pinouts with a multimeter to ensure internal wiring is
intact.
