let the air circulate.
The temperature of the player's internal mechanism is
raised because of high external temperature. Remove the

Car audio system operating hints
Radio reception
Usually, the problem with radio reception does not mean
there is a problem with your radio ± it is just the normal result
of conditions outside the vehicle.
For example, nearby buildings and terrain can interfere with
FM reception. Power lines or telephone wires can interfere
with AM signals. And of course, radio signals have a limited
range, and the farther you are from a station, the weaker its
signal will be. In addition, reception conditions change
constantly as your vehicle moves.Here are some common reception problems that probably
do not indicate a problem with your radio.
FM
Fading and drifting stations ± Generally, the effective
range of FM is about 40 km (25 miles). Once outside this
range, you may notice fading and drifting, which increase
with the distance from the radio transmitter. They are often
accompanied by distortion.
Multi±path ± FM signals are reflective, making it possible for
two signals to reach your antenna at the same time. If this
happens, the signals will cancel each other out, causing a
momentary flutter or loss of reception.
Static and fluttering ± These occur when signals are
blocked by buildings, trees, or other large objects.
Increasing the bass level may reduce static and fluttering.
Station swapping ± If the FM signal you are listening to is
interrupted or weakened, and there is another strong station
nearby on the FM band, your radio may tune in the second
station until the original signal can be picked up again.
AM
Fading ± AM broadcasts are reflected by the upper
atmosphere ± especially at night. These reflected signals
can interfere with those received directly from the radio
station, causing the radio station to sound alternately strong
and weak.
Station interference ± When a reflected signal and a signal
received directly from a radio station are very nearly the
same frequency, they can interfere with each other, making
it difficult to hear the broadcast.
