Battery operation
1. Remove the Battery cover on the rear of the unit by pushing the catch
downwards. Open the battery door.
2. Insert six LR14 (C size) batteries into the spaces in the compartment.
Take care to ensure all batteries are inserted with the correct polarity
as shown on the rear of your radio. Close the battery door.
3. When the battery drops below a certain level the low battery indicator
will light. When you see this indicator you should change the batteries as soon as it is convenient to do so. Reduced power, distortion
and a ‘stuttering’ sound are also 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 RD-55 is used via the
mains adaptor 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, fi re 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.
If you need any further advice, please call our Technical Helpline on :-

1. Place your radio on a fl at surface.
2. Insert the adaptor plug into the DC socket located on the left hand
end of your radio.
3. Plug the adaptor into a standard 13 amp mains socket outlet. Whenever
the adaptor is used, the batteries are automatically disconnected.
The AC adaptor should be disconnected from the mains supply and
the radio when not in use.
• IMPORTANT: The mains adaptor 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
adaptor should be removed from the mains socket outlet
completely.

hours of recording time. If you are using a new SD card ensure that it is
formatted correctly.
Many different brands and capacities of SD card are available. Your RD55
has been tested with the most popular cards up to 1 GB. However, there
are many different card variants available and not all cards can be guaranteed to work in the RD55. The RD55 will not work with cards greater
