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.  
Operation via an AC adaptor (not included)  
The AC adaptor for use with the R9993 should provide 6 volts DC output  
at 300mA centre pin negative (Roberts type PU6-B).  
1. Place your radio on a flat surface.  
2. 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.  
3. Plug the adaptor into a wall socket and switch on.  
The unit remains connected to the mains even when it is switched  
off. The unit is only fully isolated from the mains if the AC adaptor  
is removed from the wall socket.

General  
Do not allow this unit to be exposed to water, steam or sand. 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.  
The name plate is located on the bottom of the unit.
