ment. Take care to ensure all batteries are inserted with the correct
polarity as shown inside the battery compartment. Close the rear
door and secure the catch
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.
We would recommend for economy that the RD-10 is used via the
AC adaptor whenever possible with battery operation for occasional
or stand-by use only.
