This unit is fitted with a built-in ferrite bar aerial for use with the
MW wavebnd. This aerial is directional and it may be necessary to
rotate the set slightly for best reception.
FM reception is best obtanied by raising the telescopic aerial (1).
then angling and rotating it for best reception.
Sw reception is best obtained by raising the telescopic aerial(1)to its
Fullest extent and us-ing the radio with the aerial upright.
If reception is generally poor, select a different position I the room,
near a window perhaps.
AERIAL
SAFET SWITCH
This set is fitted with a Safety Safety Switch (17).Locted on the side
of the unit, the switch locks the radio in the ON postion

1.Ensure that the Safety Switch (17) is in
the down (off)position.
2.Pess the WM/SW Selector (3). The MW/
SW indicator (8) and the Tuning Indicator
(7) will glow.
3. Select MW at the MW/SW Band Selector
(11). The MW/SW Band Indicator (11) will
show M.
4. Adjust the Volume Control(10)by rotating
it clockwise until sound can be heard.
5. Using the Tuning Control (5)tune to the

flickers and does not stay on, this indicates that the station being
received is too weak and good stereo reception is not possible.
Set the Stero/Mnon Mode switch to MONO reception will be
improved but the stereo effect will be lost.
