Troubleshooting
The batteries seem to drain when left in the case.
Make sure unit’s volume wheel remains in the “off” position when stored in the case. It is
possible to turn units on when placing them in carrying pockets.

indicates charging is not occurring.)
Make sure unit’s volume wheel remains in the “off” position when stored in the case. It
is possible to turn units on when placing them in carrying pockets. Check that there is
power to the case, this is verified by the green LED next to the power connection being
lit. The batteries may be completely discharged. In this situation, leave the unit in the
charging case for 5-10 minutes, while the batteries are reconditioned. Verify tight
connection between charging wire and unit. Verify unit battery switch is in NiMH position.
