Battery operation
1. Remove the Battery cover on the rear of the unit by pushing the catch
in the direction of the arrow.
2. Insert four LR6 (AA size) batteries into the spaces in the compartment.
Take care to ensure all batteries are inserted with the correct polarity
as shown inside the battery compartment. Replace the battery cover.
3. Reduced power, distortion, and a ‘stuttering’ sound are all signs that
the batteries may need replacing.
4. If the radio is not to be used for any extended period of time it is
recommended that the batteries are removed from the radio.
