Casio SA-21 User Manual

eDry batteries
This unit can be powered by five AA size (SUM-3/R6P) manganese dry cell batteries. Weakened bat-
teries will result in lower volume or poor tonal quality. At this time, change batteries or shift to one
of the alternate power sources mentioned below.
To replace batteries
1) Open the battery compartment cover on the bottom of the unit and take out the used batteries.
2) Load new batteries taking care that the (+) and (—) poles are facing in the correct directions.
“It is advisable to replace all five batteries at the same time for longer battery life.
*Standard battery life is approximately 6 hours.
"If battery power drops below a certain level, the quality of the tone produced deteriorates, a totally
different tone may sound, or the demo tune or auto rhythm may become abnormal. Should any of
these symptoms occur, replace batteries as soon as possible.

An AC adaptor (AD-1, optional) is required when using household current. Use only a genuine CASIO
adaptor with the same voltage rating (100, 117, 220 or 240V) as the power supply in your area to
prevent damage to the keyboard’s internal components, Plug the AC adaptor into the AC outlet and
the cord into the unit. This will automatically cut off the battery power supply.
*Use only genuine CASIO adaptors to avoid risk of damage.
*The adaptor may become warm when left connected to an outlet. This is normal, but the adaptor should
be disconnected when not in use.
The unit is a precision instrument, made up of electronic parts. Any modification of, or tampering with
inner parts may cause problems.
