Battery operation
1. Release the catch securing the rear door of your radio.
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. Close the rear door and
secure the catch
3. Reduced power, distortion, and a ‘stuttering’ sound are all signs that
the batteries may need replacing. The batteries should be replaced
when the battery indicator flashes and "E" shows in the display.
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 R9974 is used via the
AC adaptor whenever possible with battery operation for occasional
or stand-by use only.
Using the AC adaptor
1. Insert the adaptor plug into the DC in socket on the left hand side of
your radio.
2. Plug the adaptor into a standard 13A 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. The unit is only fully isolated from the mains
if the AC adaptor is removed from the wall socket.

General
Do not allow this radio 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.
