CARE AND MAINTENANCE

Your clock radio is an example of superior design and craftsmanship. The following suggestions will help you care for your clock radio so you can enjoy it for years.

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

Handle the clock radio gently and carefully. Dropping it can damage circuit boards and cases and can cause the clock radio to work improperly.

Use and store the clock radio only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts.

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

Wipe the clock radio with a damp cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the clock radio.

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