Battery operation
1. Remove the Battery cover on the rear of the unit by pushing the
battery door in and downwards.
2. Insert four LR14 (C size) batteries into the spaces in the compart-
ment. 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 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 R9927 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 on a flat surface.
2. Plug the mains lead into the Mains 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.
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.

Trouble shooting
In case of malfunction due to electrostatic discharge, it may be neces-
sary to reset the product to resume normal operation. This may generally
be performed by turning the unit off and on. In some cases a more
complete reset may be needed, either by removing all sources of power
(battery and mains) when turned off.

Headphones
1. A Headphone Socket (3.5mm) located on the right hand end of
your radio is provided for use with either headphones or an
earpiece. Inserting the headphone plug automatically mutes the
internal loudspeaker.
IMPORTANT: Excessive sound pressure from earphones and
headphones can cause hearing loss.
General
Do not allow this unit to be exposed to dripping or splashing. 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 where ever possible as better results in terms of quality
and freedom from interference will usually be obtained than on the MW
or LW bands.
• No objects filled with liquids such as vases, shall be placed on
the radio.
• It is recommended to operate the product such that there is a minimum
distance (10cm recommended) to adjacent objects in order to
ensure good ventilation.
• The ventilation of the product should not be restricted by covering
it or its ventilation openings with items such as newspapers, table-
cloths, curtains etc.
• No naked flame sources such as lighted candles should be placed
on the product.
• It is recommended to avoid using or storing the product at extremes
of temperature. Avoid leaving the unit in cars, on window sills in
direct sunlight etc.
• The name plate is located on the bottom panel.
