Battery operation
1. Remove the battery cover on the back of the unit by sliding the cover
in the direction of the arrow.
2. Insert four LR20 (D 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.
We would recommend for economy that the RD-46 is used via the
AC adaptor whenever possible with battery operation for occasional
or stand-by use only.
1

Using the AC adaptor
The AC adaptor for use with the RD46 should provide 6 volts DC
output at 1000mA centre pin positive.
1. Insert the adaptor plug into the DC in socket on the left hand side of
your radio.
2. Plug the adaptor into a standard 13A mains socket outlet. Whenever
the adaptor is used the batteries are automatically disconnected.
The AC adaptor should be disconnected from the mains supply and
the radio when not in use.
