Battery operation  
1. Remove the Battery cover on the rear of the unit by pushing the  
battery door in and downwards.  
2. Insert four LR14 (C size) batteries into the spaces in the compart-  
ment. 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 R9927 is used on the  
mains whenever possible with battery operation for occasional or  
stand-by use only.  
Mains operation

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 of the mains lead into a wall socket and switch on  
the wall socket.

Headphones  
1. A Headphone Socket (3.5mm) located on the right hand end of your  
radio is provided for use with either headphones or an earpiece.  
Inserting the headphone plug automatically mutes the internal  
loudspeaker.  
General  
Do not allow this unit to be exposed to dripping or splashing. Do not leave  
your radio where excessive heat could cause damage such as in a  
parked car where the heat from the sun can build up even though the  
outside temperature may not seem too high. It is recommended that the  
FM band be used where ever possible as better results in terms of quality  
and freedom from interference will usually be obtained than on the MW  
or LW bands.
