MAINTENANCE

Your Optimus 85 × 4 High Power 4-Channel Trunk Mount Amplifier is an example of superior design and craftsmanship. The following suggestions will help you care for your (product name) so you can enjoy it for years.

Keep the amplifier dry. If it gets wet, wipe it dry immediately. Liq- uids might contain minerals that can corrode the electronic cir- cuits.

Handle the amplifier gently and carefully. Dropping it can damage circuit boards and cases and can cause the amplifier to work im- properly.

Use and store the amplifier only in normal temperature environ- ments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts.

Keep the amplifier away from dust and dirt, which can cause pre- mature wear of parts.

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

Modifying or tampering with the amplifier’s internal components can cause a mal- function and might invalidate your amplifier’s warranty. If your amplifier is not per- forming as it should, take it to your local Radio Shack store for assistance.
