102 Saab 9-5 Audio System
Radio waves, FM/AM
FM radio waves radiate in straight lines from
the transmitter. Because such waves do not
follow the curvature of the Earth, their
strength becomes weaker the further they
travel.
AM waves, on the other hand, are reflected
off the ionosphere, thus greatly extending
their range.
Sources of AM interference
AM reception is prone to interference, e.g.
from electrical systems on other vehicles,
high-tension power lines and lightning.
Adjusting the frequency steps North
America/Europe
If the car is taken from North America to
Europe, the radio’s frequency steps can be
adjusted.
• Press and hold (mid-segment)
and switch the radio on at the same time.
The preset stations will be cancelled and
replaced by default frequencies.
