Some portable audio equipment may be susceptible to certain types of electronic noisepresent in the vehicle's 12V power outlet.

Here are two ways to eliminate this type of interference:

If the audio device is capable of being self-powered (battery), use it that way insteadof plugging it into the vehicle's power outlet.Have the customer purchase a Ground Loop Isolator, such as *Radio Shack Catalog #270-054.This device plugs in between the radio and the customer's audio device. It is packedwith one included Y-Adapter. If purchasing the *Radio Shack product, you will requirean additional Y-Adapter (Catalog #274-369). This device should be installed betweenthe audio player and the AUX input of the vehicle radio. These catalog numbers arestockednationally at *Radio Shack Retail Stores in the U.S. and are currently available.Other similar products are available through other electronics or car stereo retailersdefined as Ground Loop Isolators.Parts Information

Parts are currently available nationally in the U.S. through *Radio Shack retail locationsor through the mail at Radio Shack direct ordering 1-800-843-7422. In Canada, partsare available nationally through *The Source By Circuit City retail locations or atwww.thesourcecc.com.
