# RADIO SPEAKERS 'POP' WHEN PLAY. A CASSETTE W/CELL PHONE

#### SUBJECT: Radio Speakers "Pop" When Playing a Cassette with Cellular Phone Powered On in Vehicle (Use Exterior Cellular Phone Antenna)

#### MODELS AFFECTED: 1991-1994 Saturns equipped with AM/FM stereo and cassette player

CONDITION: An intermittent popping noise from the radio speakers may be heard when playing an audio cassette with a cellular phone powered On and the cellular phone antenna in the vehicle. Condition may occur, with phone powered On, whether or not a call is taking place.

CAUSE: The antenna on the cellular phone is too close to the radio causing electrical impulses from the cellular phone to be amplified in the radio. This occurs when the cellular phone receiver switches cells or power levels.

CORRECTION: Inform customer that an exterior clip - on or window glue - on type cellular phone antenna instead of an interior cellular phone antenna must be used. Exterior mounted cellular phone antennas are available from cellular phone retailers.

General Motors bulletins are intended for use by professional technicians, not a "do-it-yourselfer". They are written to inform those technicians of conditions that may occur on some vehicles, or to provide information that could assist in the proper service of a vehicle. Properly trained technicians have the equipment, tools, safety instructions and know-how to do a job properly and safely. If a condition is described, do not assume that the bulletin applies to your vehicle, or that your vehicle will have that condition. See a General Motors dealer servicing your brand of General Motors vehicle for information on whether your vehicle may benefit from the information.
