Automatic Antenna
The antenna switch can be actuated
with the radio switched on.
• If the antenna switch is engaged
in the "max" position, the antenna
extends fully.
Note:
For most conditions the antenna
should normally be in this position.
• If the antenna switch is in the cen­
ter position, the antenna extends
automatically to medium height,
• 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 cen­
ter position, the antenna will
extend to medium height. The an­
tenna 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.
