Battery operation

1.

Remove the 

Battery cover

 on the rear of the unit by pushing the

catches in the direction of the arrows.

2.

Insert four 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 R9904 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 

Mains socket

 located on the rear of your

radio ensuring that the plug is pushed fully into the socket.

3.

Plug the other end into a wall socket and switch on. The

 Mains

indicator

 will light up indicating that the radio is connected to the

mains supply.
