Care and Maintenance

Your RadioShack DX-397 AM/FM/SW 12-Band Portable Receiver is an example of superior design and craftsmanship. The following suggestions will help you care for your receiver so you can enjoy it for years.

Keep the receiver dry. If it gets wet, wipe it dry imme- diately. Liquids can contain minerals that can cor- rode the electronic circuits.

Use and store the receiver only in normal tempera- ture environments. Temperature extremes can shorten the life of electronic devices, damage batter- ies, and distort or melt plastic parts.

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

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

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

Use only fresh batteries of the required size and rec- ommended type. Always remove old and weak bat- teries. They can leak chemicals that destroy electronic circuits.

Modifying or tampering with the receiver’s internal components can cause a malfunction, invalidate your receiver’s warranty and void your FCC authorization to operate it. If your receiver is not operat- ing as it should, take it to your local RadioShack store for assis- tance.
