Autom atic Antenna
The antenna switch can be actuated
with the radio switched on and the
key in steering lock positions “ 1”
or “ 2 ” .
• If the antenna switch is in center
position, the antenna extends
autom atically to a specific
height,
• if the antenna switch is engaged
in the “ m ax” position, the
antenna extends fully,
• if the antenna switch is engaged
in the “ o ff” position, the
antenna w ill not extend or w ill
retract completely.
The height of the antenna can fu r­
therm ore be adjusted continuously
by actuating the antenna switch:
• If the antenna switch is in center
position, the antenna w ill extend
to the specific height. The
antenna can be further extended
or retracted to any height by
rocking the switch (not engaging
it).
• If the antenna is to be retracted,
e. g. fo r playing cassettes,
engage switch in “ o ff” position.
When 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 -o f-sig ht” .
Reflections or “ dead sp ots” may
cause cancellations or loss of the
signal as well as strong signal over­
loading o r capture.
Lowering the antenna height in
strong signal areas may elim inate
many of the resulting problem s and
restore good tone quality. However,
fringe area reception requires the
full antenna length to capture weak
incom ing signals. The antenna can
be operated by depressing the re­
spective side of the rocker switch.
FM Stereo Reception
When tuned to a FM stereo station,
the 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 effects
may be even more noticeable. The
noisefree broadcast range, there­
fore, is somewhat less and accurate
tuning to the strongest available
stereo stations is required, especial­
ly fo r fringe area reception.
Your radio is equipped with a speci­
ally designed Stereo D ecoder which
autom atically switches the radio
from stereo to mono reception if the
signal becomes too weak. However,
the Stereo Indicator Light remains
lit to avoid the distracting flicker at
short-tim e signal changes. The radio
w ill return to the stereo mode auto­
m atically when signal strength per­
mits it.
