Care and Maintenance
Your Optimus STAV-3780 Audio/Video Receiver is an example of superior design and craftsmanship. The following
suggestions will help you care for the receiver so you can enjoy it for years.
Keep the receiver dry. If it gets wet, wipe it dry immediately. Liquids can
contain minerals that can corrode the electronic circuits.
Handle the receiver gently and carefully. Dropping it can damage its cir-
cuit boards and can cause the receiver to work improperly.
Use and store the receiver and its remote control only in normal tem-
perature environments. Temperature extremes can shorten the life of
electronic devices, damage batteries, and distort or melt plastic parts.
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 recommended size and type in the remote
control. Always remove old or weak batteries. They can leak chemicals
that can destroy electronic circuits.
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 it. If the receiver is not operating as it should, take
it to your local RadioShack store for assistance.
