Battery operation  
Reduced power, distortion, and a ‘stuttering’ sound are all signs that the  
battery may need replacing.  
If the radio is not to be used for any extended period of time it is  
recommended that the battery is removed from the radio.  
1. Remove the battery cover on the base of the unit by unscrewing the  
retaining stud using a suitable coin or screwdriver.  
2. Fit the battery IEC 6F100 (PP9) to the connector.  
3. Replace the battery cover and refit the stud.  
Mains operation (via AC adaptor)  
The AC adaptor for use with the R761 should provide 9 volts DC output  
at 300mA centre pin negative (Roberts type PU609).  
1. Insert the adaptor plug into the DC socket on the left side of your  
radio. Plug the adaptor into a standard 13A mains socket outlet.  
Whenever the adaptor is used the batteries are automatically  
disconnected.  
2. The AC adaptor should be disconnected from the mains supply and  
the radio when not in use.  
We would recommend for economy that the R761 be used via the AC  
adaptor whenever possible with battery operation for occasional or  
stand-by use only.

Headphones  
1. A Headphone Socket (3.5mm) located on the left hand end of the  
top panel 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 wherever possible as better results in terms of quality  
and freedom from interference will usually be obtained than on the MW  
or LW bands.
