LED functions work. How come?
In some cases, if your radio is left on for an extended amount of time after the
battery pack is fully depleted, the microprocessor inside the radio may have
locked up and disabled the radio functions. It will be necessary to unplug the
battery pack, remove any “AA” batteries and cover the solar panel for 15 minutes
(or place the radio in a dark area). This will allow a reset of the processor.
Re-insert the battery pack and “AA” batteries (if desired), then using the hand
crank, wind the radio at a good pace for 90 seconds and then try the radio
functions.

The rechargeable battery pack may be depleted. Charging the unit for a few
minutes should clear up the sound.

The simple answer is to “exercise” the batteries to condition them for an optimal
charge. To do this, charge the batteries to full and then discharge them
completely. Performing this procedure about 3 times will bring your batteries to

No. We do not recommend having the AC Adapter connected to the radio while
charging your cell phone or other devices.

Hard winding of the Dynamo Crank on the CC Solar Observer is usually due to
a low charge on the internal battery pack. For best results, continue winding the
Dynamo Crank and try winding at a rate of two full turns per second. Another
option is to use the optional AC Charging Adapter (sold separately) to fully charge
the internal battery pack.
