CARE AND MAINTENANCE

This Radio Shack AM/FM Stereo Headset with Digital Tuning is an example of superior design and craftsmanship. The following suggestions will help you care for it so you can enjoy it for years.

Keep the headset dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits.

Use only fresh batteries of the required size and type. Always remove old or weak batteries. They can leak chemicals and cause damage to the electronic circuits.

Handle the headset gently and carefully. Dropping it can damage the circuit board and case.

Use and store the headset only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, damage batteries, and distort or melt plastic parts.

Keep the headset away from dust and dirt, which can cause premature wear of parts.

Modifying or tampering with the headset's internal components can cause a malfunction, invalidate its warranty and void your FCC authorization to operate it. If the headset is not performing as it should, take it to your local Radio Shack store for assistance.
