ROBERTS R9993 Band Portable Radio - Battery operation

Remove the Battery cover on the rear of the unit by pushing the catch in the direction of the arrow.
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.
Reduced power, distortion, and a ‘stuttering’ sound are all signs that the batteries may need replacing.
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.

Operation via an AC adaptor (not included)
Please read the safety leaflet provided before using an adaptor.
The AC adaptor for use with the R9993 should provide 6 volts DC output at 300mA, centre pin negative. (Adaptor not included)

Place your radio on a flat surface.
Plug the adaptor lead into the DC input socket located on the left hand side end of your radio ensuring that the plug is pushed fully into the socket. The batteries will be automatically disconnected.
Plug the adaptor into a wall socket and switch on.
