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 looking
new. Do not use harsh chemicals, cleaning solvents, or strong deter-
gents to clean the keyboard.
Modifying or tampering with the keyboard's internal components can cause a mal-
function and might invalidate its warranty and void your FCC authorization to oper-
ate it. If your keyboard is not performing as it should, take it to your local
RadioShack store for assistance.
