Radio Reception - Saturn 2007 Ion Owner's Manual

Radio Reception

Frequency interference and static can occur
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 boost the power levels during the
day, and then reduces 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 the radio.
FM Stereo
FM stereo gives the best sound, but FM signals
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
the loss of XM™ signal for a period of time.
The radio might display NO XM SIGNAL to
indicate interference.
Cellular Phone Usage
Cellular phone usage could cause interference
with your vehicle's radio. This interference
could occur when making or receiving phone calls,
charging the phone's battery, or simply having
the phone on. This interference is an increased
level of static while listening to the radio. If static is
received while listening to the radio, unplug the
cellular phone and turn it off.
