General
Fuse
Do not allow this unit to be exposed to water, steam or sand. Do not leave
the unit where excessive heat could cause damage such as in a parked car
wheretheheatfromthesuncanbuildupeventhoughtheoutsidetempera-
ture may not seem too high. It is recommended that the FM band be used
were ever possible as better results in terms of quality and freedom from
interference will usually be obtained than on the MW or LW bands.
When replacing the fuse only a 3A ASTA approved to BS1362 type should
be used and be sure to re-fit the fuse cover.
IF IN DOUBT - CONSULT A COMPETENT ELECTRICIAN.
Replacement fuse holders are available from Roberts Radio at the
address shown on the rear of this manual.

To change from battery to mains operation, simply plug the mains lead into
the mains input socket (9) on the left hand end of the unit. Mains operation
is shown by the mains indicator (8). The batteries will be automatically
disconnected. It does not matter which way round the plug is inserted but
make sure it is fully pushed home. The other end should be plugged into a
domestic supply socket.
The wires in the mains lead are coloured in accordance with the following
codes :-
BLUE - NEUTRAL
BROWN - LIVE
Asthesecoloursmaynotcorrespondwiththecolouredmarkingsidentifying
the terminals in your plug, proceed as follows:
The wire coloured BLUE must be connected to the terminal marked N or
colouredBLACK.
Aerials
On FM fully extend the telescopic aerial (5), angle and rotate for best
reception.
The wire coloured BROWN must be connected to the terminal marked L or

On MW and LW stations are received on the built in ferrite rod aerial, rotate
the entire radio to the position giving best reception.
The telescopic aerial is inoperative on MW and LW.
