Aerials
The lead connecting earphones to your radio acts as an FM aerial
when plugged into the earphone socket. The lead should be extended
as much as possible to increase FM reception. There is a separate
directional aerial built into the radio for MW and LW reception. To
achieve the best MW/LW reception, it may be necessary to rotate the
radio.
Loudspeaker On/Off switch & Earphones
Your radio may be operated using the built in loudspeaker or the
earphones supplied.
1. The built in loudspeaker may be switched on by sliding the Stereo/
Mono/Speaker switch to the ‘Speaker’ position.

tail aerial or earphones should be inserted into the earphone jack.
3. To operate your radio via earphones, plug the earphones into the
earphone jack and slide the Stereo/Mono/Speaker switch to the
‘Stereo’ position.
