gaged in the upper position,
the antenna extends fully.

center position, the antenna
extends automatically to me­
dium height,
• if the antenna switch is en­
gaged in the lower position, the
antenna will not extend or will
retract completely.
The height of the antenna can be
adjusted to any intermediate
position by actuating the antenna
switch:
• If the antenna switch is in the
center position; the antenna
will extend to medium height.
The antenna can be further ex­
tended or retracted to any
height by rocking the switch
(not engaging it).
• If the antenna is to be retract­
ed, e.g. going through car
wash etc., engage switch in
lower position.
When the key is turned to steering
lock position 0 or the radio is
turned off, the antenna will retract
completely.
