Radio Reception
You may experience frequency interference and
static during normal radio reception if items
such as cellphone chargers, vehicle convenience
accessories, and external electronic devices
are plugged into the accessory power outlet. If
there is interference or static, unplug the item from
the accessory power outlet.
AM
The range for most AM stations is greater than for
FM, especially at night. The longer range can
cause station frequencies to interfere with each
other. For better radio reception, most AM
radio stations will boost the power levels during
the day, and then reduce these levels during
the night. Static can also occur when things like
storms and power lines interfere with radio
reception. When this happens, try reducing the
treble on your radio.
FM Stereo
FM stereo will give the best sound, but FM signals
will reach only about 10 to 40 miles (16 to 65 km).
Tall buildings or hills can interfere with FM
signals, causing the sound to fade in and out.
XM™ Satellite Radio Service
XM™ Satellite Radio Service gives digital radio
reception from coast-to-coast in the 48 contiguous
United States, and in Canada. Just as with FM,
tall buildings or hills can interfere with satellite
radio signals, causing the sound to fade in and out.
In addition, traveling or standing under heavy
foliage, bridges, garages, or tunnels may cause
loss of the XM™ signal for a period of time.
The radio may display NO SIGNAL to indicate
interference.
Care of the Cassette Tape Player
A tape player that is not cleaned regularly
can cause reduced sound quality, ruined
cassettes, or a damaged mechanism. Cassette
tapes should be stored in their cases away
from contaminants, direct sunlight, and extreme
heat. If they are not, they may not operate properly
or may cause failure of the tape player.
