Radio reception factors

Three factors can affect radio reception:

• Distance/strength. The further an FM signal travels, the weaker it is.

The listenable range of the average FM station is approximately 40 km

(24 miles). This range can be affected by “signal modulation.” Signal

modulation is a process radio stations use to increase their

strength/volume relative to other stations.

• Terrain. Hills, mountains and tall buildings between your vehicle’s

antenna and the radio station signal can cause FM reception problems.

Static can be caused on AM stations by power lines, electric fences,

traffic lights and thunderstorms. Moving away from an interfering

structure (out of its “shadow”) returns your reception to normal.

• Station overload. Weak signals are sometimes captured by stronger

signals when you pass a broadcast tower. A stronger signal may

temporarily overtake a weaker signal and play while the weak station

frequency is displayed.

The audio system automatically switches to single channel reception if it

will improve the reception of a station normally received in stereo.

Audio system warranties and service

Refer to the “Warranty Guide” for audio system warranty information.
