Troubleshooting
Error: Ensure CPX is docked or connect to a battery
higher than 11V.

1. The CPX should be firmly seated into the
docking station.
2. The CPX should not be removed from the
docking station during the update.
3. Make sure the power supply is plugged into an
appropriate outlet and the barrel connector is
firmly inserted into the docking station.
• To check the power supply, use a multimeter and test for 12V on the power
supply barrel connector. If 12V is not
present, a new power supply is required
for the docking station.
4. Inspect the charging pins in the base of the
docking station and the charging connections
on the bottom of the CPX. Pins should depress
easily and charging connections should be
clean and free of debris.
• Using a multi-meter, test for 12V on the
charging pins. If 12V is not present a new
docking station is required.
5. If power supply and docking station are
working properly and this error continues, call
Technical Support (information below).
6. If connected to a battery, check battery
voltage and ensure it is greater than 11V.
