Radio/Generai Troubleshooting
RADIO RECEPTION
Set the TAPE/RADIO selector to RADIO.
Adjust the sound with the controls VOLUME
and TONE.
You may connect stereo headphones with
3 5 mm plug to socket O. The loudspeaker
IS then muted.
Select the wave band using BAND selector.
Tune to a radio station using TUNING knob.
(SW and LW not on all versions).
For FM, pull out the telescopic aerial. To
improve FM-reception, incline and turn the
aerial. Reduce its length if the FM-signal is
too strong (very close to a transmitter).
For AM/MW and LW (Medium and Long
Wave), the set is provided with a built-in
aerial, so there is no need to use the
telescopic aerial. The aerial can be directed
by turning the whole set.
For Short Wave (SW), the telescopic aerial
must be pulled out and placed in the vertical
position. To improve SW-reception, vary the
length of the aerial.
The set is switched off if the TAPE/RADIO
selector is in position TAPE and the recorder
buttons are released.
MAINTENANCE
Clean the parts indicated after every 50 hours
of operation or, on average, once a month.
If a fault occurs, first check the points listed
below before taking the set for repair. If you
are unable to remedy a problem by following
these hints, consult your dealer or service
centre.
Warning: Under no circomstances should you
try to repair the set yourself, as this would
invalidate the guarantee
