Battery operation  
1. Remove the Battery cover on the rear of the unit by pushing the  
catches in the direction of the arrow.  
2. Insert four LR14 (C size) batteries into the battery compartment.  
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 your radio cassette 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 SC9911 is used on the  
mains whenever possible with battery operation for occasional or  
stand-by use only.  
IMPORTANT: The batteries should not be exposed to excessive  
heat such as sunshine, fire or the like. After use, disposable  
batteries should if possible be taken to a suitable recycling centre.  
On no account should batteries be disposed of by incineration.  
Mains operation  
1. Place your radio cassette on a flat surface.  
2. Plug the mains lead into the Mains socket located on the rear of your  
radio cassette ensuring that the plug is pushed fully into the socket.  
3. Plug the other end into a wall socket and switch on. The batteries  
will be automatically disconnected.  
ON  
IMPORTANT: The mains plug is used as the means of connecting  
the radio to the mains supply. The mains socket used for the radio  
must remain accessible during normal use. In order to disconnect the  
radio from the mains completely, the mains plug should be removed  
from the mains socket outlet completely.

Listening to the radio  
FM operation  
1. Set the Function switch to the 'Radio' position.  
2. Select 'FM' using the Waveband switch.  
3. Adjust the Volume control until a hissing sound is heard.  
4. The Telescopic aerial which is only operational on FM, should be  
fully extended.  
5. Carefully tune to the desired station using the Tuning control.  
6. Angle and rotate the Telescopic aerial to a position giving the best  
reception. A knuckle joint at the base of the aerial allows this  
movement and an angle of 45 degrees will usually be satisfactory.  
The FM band is marked in Megahertz (MHz).  
Volume  
7. To receive stereo broadcasts set the Mono/Stereo to the 'Stereo'  
position the Stereo indicator will light up. If the station being  
received is weak some hiss may be audible, to reduce the hiss set  
the Mono/Stereo switch to the 'Mono' position to return to mono  
operation.
