Your Optimus Concertmate 410 Portable Electronic Keyboard is an example of su-
perior design and craftsmanship. The following suggestions will help you care for
your Concertmate 410 so you can enjoy it for years.

Keep the Concertmate 410 dry. If it gets wet, wipe it dry immediately.
Liquids might contain minerals that can corrode the electronic cir-
cuits.

Handle the Concertmate 410 gently and carefully. Dropping it can
damage circuit boards and cases and can cause the keyboard to
work improperly.

Use and store the Concertmate 410 only in normal temperature envi-
ronments. Temperature extremes can shorten the life of electronic
devices and distort or melt plastic parts.

Keep the Concertmate 410 away from dust and dirt, which can cause
premature wear of parts.

Use only fresh batteries of the required size and type. Old batteries
can leak chemicals that damage your keyboard’s electronic parts.

Wipe the Concertmate 410 with a damp cloth occasionally to keep it
looking new. Do not use harsh chemicals, cleaning solvents, or
strong detergents to clean the Concertmate 410.

Modifying or tampering with the Concertmate 410’s internal components can cause
a malfunction, might invalidate its warranty, and void your FCC authorization to use
it. If your Concertmate 410 is not performing as it should, take it to your local Ra-
dioShack store for assistance.
