For adjustments to your car radio and
correct operation of its controls,
please refer to the accompanying
operation manual.
The reception and reproduction qual-
ity of any mobile radio installation
depends on the range of the transmit-
ter you wish to pick up and the align-
ment of the aerial.
Interference from high-tension over-
head wires, but also buildings and
natural obstructions, may cause noise
and signal deterioration which cannot
be avoided even if the vehicle's own
interference suppression systems are
in good working order.
Climatic influences such as sun spots,
fog, rain or falling snow also influence
radio reception.
The MW, LW and SW wavebands can
be heard a long way from the trans-
mitter, because the signals spread out
both as ground waves and through
the air, reflected by the ionosphere.
VHF (FM) reception provides far
higher listening quality than any of the
AM wave bands. However, a VHF
transmitter's range is limited to about
100 kilometres, since the signals
travel only by line of sight.
Car phones not recommended by
BMW or other mobile phones could
cause radio interference. This takes
the form of a low-pitched humming in
the loudspeaker system.
Mobile communication systems (car
telephones, two-way radio etc.) can
cause interference if they are not
approved for use in your car. Since
BMW cannot examine and test each
product, it is unable to accept any
responsibility for the installation of
items it has not approved. Before pur-
chasing any such equipment you are
recommended to consult your BMW
service station.
Furthermore, in order to safeguard your
BMW's operating reliability, do not
operate any in-car telephones or other
mobile radio equipment with an aerial
inside the car or with an aerial which is
not attached to the outside of the car.
Detach the car phone aerial before
driving on to a car train.
