Automatic 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 the
center position, the antenna
extends automatically to medium
height,
• if the antenna switch is engaged in
the " max." position, the antenna
extends fully,
• if the antenna switch is engaged in
the "off" position, the antenna will
not extend or will retract com­
pletely.
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 extended or
retracted to any height by rocking
the switch (not engaging it).
• If the antenna is to be retracted,
e.g. going through car wash, etc.,
engage switch in "off" position.
When the key is turned to steering lock
position 0 or the radio is turned off, the
antenna will retract completely.
