catch downwards. Open the battery door.

ment. Take care to ensure all batteries are inserted with the correct  
polarity as shown on the rear of your radio. Close the battery door.  
3. The Low battery indicator, 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-15 is used via the  
mains adaptor whenever possible with battery operation for occa-  
sional or stand-by use only.  
Using the AC adaptor  
Your radio is supplied with a Mains Adaptor.  
1. Place your radio on a flat surface.  
2. Insert the adaptor plug into the DC socket located on the left hand  
end of your radio.  
3. Plug the adaptor into a standard 13 amp mains socket outlet.  
Whenever the adaptor is used, the batteries are automatically  
disconnected.

the radio when not in use.
