Radio Reception

Frequency interference and static

can occur during normal radio

reception if items such as cell phone

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 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 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.

Cellular Phone Usage

Cellular phone usage may cause

interference with the vehicle’s radio.

This interference may occur when

making or receiving phone calls,

charging the phone’s battery,

or simply having the phone on. This

interference causes 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.

Fixed Mast Antenna

The ﬁxed mast antenna can

withstand most car washes without

being damaged, or it can be

removed. If the mast should ever

become slightly bent, straighten

it out by hand. If the mast is badly

bent, replace it.

Check occasionally to make sure

the mast is still tightened to the

antenna base located on the roof of

the vehicle.
