A utom atic Antenna
The antenna sw itch can be a ctu ­
ated w ith the radio sw itched on
and the key in steering lock posi­
tions "1" or "2".
• If the antenna sw itch is in
center position, the antenna ex­
tends autom atically to a speci­
fic height,
• if the antenna sw itch is
engaged in the "m a x" position,
the antenna extends fully.
• if the antenna sw itch is
engaged in the "o ff" position,
the antenna w ill not extend or
w ill retract com pletely.
The height o f the antenna can
furtherm ore be adjusted c o n tin ­
uously by actuating the antenna
sw itch:
• If the antenna sw itch is in
center position, the antenna will
extend to the specific height.
The antenna can be fu rthe r ex­
tended or retracted to any
height by rocking the sw itch

(not engaging it).
• If the antenna is to be re­
tracted, e. g. fo r playing cas­
settes, engage sw itch in "o ff"
position.
W hen the key is turned to steering
lock position "0" or the radio is
turned off, the antenna w ill retract
completely.
FM Reception
FM signals travel in a "line-of-
sight". Reflections or "dead spots"
may cause cancellations or loss o f
the signal as well as strong signal
overloading or capture.
Lowering the antenna height in
strong signal areas may eliminate
many o f the resulting problems and
restore good tone quality. H ow ­
ever, fringe area reception requires
the full antenna length to capture
weak incom ing signals. The an­
tenna can be operated by depress­
ing the respective side o f the
rocker sw itch.
FM Stereo Reception
W hen tuned to a FM stereo station,
the red Stereo Indicator Light w ill
light up. Because more inform ation
is carried in the FM stereo signal
than in FM m onoraul broadcasts,
flutter, cancellation and capture e f­
fects may be even more noticeable.
The noisefree broadcast range,
therefore, is som ewhat less and
accurate tuning to the strongest
available stereo stations is required,
especially fo r fringe area reception.
