Battery operation
1. Remove the Battery cover on the rear of the unit by pushing the
catches in the direction shown by the arrows.
2. Insert four LR20 (D size) batteries into the spaces in the compartment. Take care to ensure all batteries are inserted with the correct
polarity as shown inside the battery compartment. Replace the
battery cover.
note : the batteries provide power for the clock/memory
backup and must be fitted at all times.
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 R9943 is used on the
mains whenever possible with battery operation for occasional or
stand-by use only.
Battery replacement
1. The battery indicator will appear in the display (not when connected
to mains) for 7 seconds after the radio is switched on or off. The
battery indicator will show when the batteries are new. The
batteries should be replaced when the battery indicator shows
. If the battery power is too weak to switch on the radio the
battery indicator will flash . After removing the batteries you
have approximately 3 minutes to replace the batteries after which
the clock and memory information will be lost.
Mains operation
1. Place your radio on a flat surface.
2. Plug the mains lead into the 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.

2. Ensure that the radio switched off.
3. Press and hold down Time set button until the hours digits begin
to flash in the display.
4. Press the Tuning up/down buttons to set the required hour. The
clock uses the 24 hour system e.g. 2:00pm is shown as 14:00

Operating you radio
Your radio is equipped with four tuning methods:- Scan tuning, Rotary
tuning, Manual tuning, and Memory preset tuning. When switched on
your radio will display the waveband and frequency in use. A graphical
display similar to a conventional radio tuning dial will be shown in the
bottom half of the display.
Scan tuning
1. Press the On/Off button to switch on your radio.
2. Select the required waveband by repeatedly pressing the Band
button. For the FM waveband fully extend the Telescopic aerial
angle and rotate, if necessary, to obtain best reception.
3. Press and hold down either the Tuning up or Tuning down buttons
for more the 0.5 sec to commence scan tuning.
4. Your radio will scan the selected waveband and stop automatically
when it finds a station of sufficient strength. The tuning indicator
and station frequency will appear in the display.
5. To recommence scan tuning, press and hold down either the
Tuning up or Tuning down buttons for more the 0.5 sec.
6. When the waveband end is reached the radio will bleep and continue
tuning from the opposite waveband end.
7. Set the Volume control and Tone controls to the desired settings.
8. To switch off your radio press the On/Off button.
