Using Batteries

Your keyboard can use six AA batteries
(not supplied) for power. For the best
performance and longest life, we recom-
mend RadioShack alkaline batteries.
Cautions:
• Use only fresh batteries of the
required size and recommended
type.
• Do not mix old and new batteries,
different types of batteries (stan-
dard, alkaline, or rechargeable), or
rechargeable batteries of different
capacities.
Follow these steps to install batteries.

2. While pressing the tab on the bat-
tery compartment cover on the bot-
tom of the keyboard, pull up the
cover to remove it.
3. Place the batteries in the compart-
ment as indicated by the polarity
symbols (+ and – ) marked below the
compartment.
4. Replace the cover.
When the keyboard stops operating
properly, replace the batteries.
Warning: Dispose of old batteries
promptly and properly. Do not burn or
bury them.
Caution: If you do not plan to use the
keyboard with batteries for a week or
more, remove the batteries. Batteries
can leak chemicals that can destroy
electronic parts.
