CARE AND MAINTENANCE
Your Optimus Concertmate 975 Portable Stereo Musical Instrument is an exam-
ple of superior design and craftsmanship. The following suggestions will help you
care for your keyboard so you can enjoy it for years.
Keep the keyboard dry. If it gets wet, wipe it dry immediately. Liq-
uids might contain minerals that can corrode the electronic cir-
cuits.
Use and store the keyboard only in normal temperature environ-
ments. Temperature extremes can shorten the life of electronic
devices, damage batteries, and distort or melt plastic parts.
Keep the keyboard away from dust and dirt, which can cause pre-
mature wear of parts.
Handle the keyboard gently and carefully. Dropping it can dam-
age circuit boards and cases and can cause the keyboard to work
improperly.
Use only fresh batteries of the required size and recommended
type. Batteries can leak chemicals that damage your keyboard?s
electronic parts.
Wipe the keyboard with a damp cloth occasionally to keep it look-
ing new. Do not use harsh chemicals, cleaning solvents, or strong
detergents to clean the keyboard.
Modifying or tampering with the keyboard?s internal components can cause a
malfunction and might invalidate your keyboard?s warranty and void your FCC
authorization to operate it. If your keyboard is not performing as it should, take it
to your local RadioShack store for assistance.
