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.
