Model 99 (160-0537) Care and Maintenance Faxback Doc. # 7935 Your Optimus Model 99 VHS VCR is an example of superior design and craftsmanship. The following suggestions will help you care for the VCR so you can enjoy it for years. Keep the VCR dry. If it gets wet, wipe it dry immediately. Liquids can contain minerals that corrode the electronic circuits. Handle the VCR gently and carefully. Dropping it can damage its circuit boards and cases and cause it to work improperly. Use and store the VCR only in normal temperature environments. Temperature extremes can shorten the life of electronic devices, and distort or melt plastic parts. Keep the VCR away from dust and dirt, which can cause premature wear of parts. Wipe the VCR's front panel and other exterior surfaces with a clean, soft, dry cloth. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean the VCR. Modifying or tampering with your VCR's internal components can cause a malfunction and might invalidate the VCR's warranty and void your FCC authorization to operate it. If your VCR is not operating properly, take it to your local Radio Shack store for assistance. Servicing Your VCR There are no user-serviceable parts inside your VCR. If you encounter a problem that you cannot correct using this manual and its troubleshooting guide, take the VCR to your local Radio Shack store for assistance. Cleaning the Video Heads Dirty video heads can cause the playback picture to become blurred even though the audio signal is clear. Serious problems require cleaning by a trained technician. For more head cleaning information, contact your local Radio Shack store. Storing Your Video Cassettes Unless you are making an automatic timer recording, eject and store the cassette before you turn off the VCR. This helps protect the cassette and the VCR's internal mechanisms from dust. Place your video cassettes in their protective boxes and store them in a cool, dry, dust-free environment. Store the cassettes on end, not on their sides. This prevents improper settling of the cassette's spools. NOTE: Tape can become would too tightly around the cassette's spools after numerous playings. This can cause the cassette to improperly load and automatically eject when you insert it. On most cassettes there is a brake-release plunger on the bottom center of the cassette. Use the tip of a pen or pencil to press the plunger. This loosens the tape. Clean heads only when picture quality is affected. (ALL-11/11/94)
