Important: All GM factory-equipped audio systems have ungrounded speakers. Installing after-market tape players, citizen band radios or other units that use the factory speakers may damage the audio system or impair the operation of the after-market unit.

### FM Radio Reception

The FM tuner operates on a band from 87.7 MHz to 107.9 MHz. Optimum FM radio reception range is usually limited to a maximum of 16 to 64 kilometers (10 to 40 miles). The range depends upon the following conditions:

• | The terrain

• | The atmospheric conditions

• | The station power

• | The antenna height

• | The distance from the transmitter.

Signal flutter or noise may result from the following:

• | Tall buildings

• | Hills

• | Other objects

You may eliminate this problem by tuning to a stronger station.

### AM Radio Reception

The AM tuner operates on a band from 530 kHz to 1710 kHz.

The range of most AM stations is greater than FM, especially at night. The longer range may cause stations to interfere with each other. AM reception is also subject to noise interference from storms, power lines, etc. Reduce the treble in order to help reduce the noise.
