Battery operation

1. Remove the Battery cover on the rear of the unit by pushing the

battery door in and downwards. .

2. Insert six  LR14 (C 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-18 is used on the
mains whenever possible with battery operation for occasional or
stand-by use only.

Mains operation

1. Place your radio on a flat surface.

2. Plug the mains lead into the Socket located on the rear of your radio

ensuring that the plug is pushed fully into the socket.

3. Plug the other end of the mains lead into a wall socket and switch on

the wall socket.
