DX-390 (200-0214) Care and Maintenance Faxback Doc. # 3614 CARING FOR THE RECEIVER Your Realistic DX-390 Receiver is an example of superior design and craftsmanship. The following suggestions will help you care for your receiver so that you can enjoy it for years. Use only fresh batteries of the recommended size and type. Never leave dead or weak batteries in the receiver. They might leak chemicals that can damage the receiver. If you ar not going to use the receiver for several days, remove the batteries. Keep the receiver dry. If it does get wet, wipe it dry immediately. Liquids can contain minerals that can corrode the electronic circuits. Use and store the receiver only in normal temperature environments. Temperature extremes can shorten the life of electronic devices and distort or melt plastic parts. Keep the receiver away from dust and dirt, which can cause premature wear of parts. Handle the receiver gently and carefully. Dropping it can damage circuit boards and can cause the receiver to work improperly. Wipe the receiver with a dampened cloth occasionally to keep it looking new. Do not use harsh chemicals, cleaning solvents, or strong detergents to clean your receiver. Modifying or tampering with your receiver's internal components can cause a malfunction and might invalidate the receiver's warranty and void your FCC authorization to operate the receiver. If your receiver is not performing as it should, take it to your local Radio Shack store where our personnel will assist you. THE FCC WANTS YOU TO KNOW Your receiver might cause interference on other radio/TV devices even when it is operating properly. To determine whether your receiver is causing the interference, turn off your receiver. If the interference goes away, your receiver is causing the interference. Try to eliminate the interference by: Moving your receiver away from the other device. Connecting your receiver to an outlet that is on a different electrical circuit from the other device. Contacting your local Radio Shack store for help. If you cannot eliminate the interference, the FCC requires that you stop using your receiver. (ALL-12/13/94)
