apart.
(If a battery leaks, clean out the battery compartment of the unit immediately, taking
care to avoid letting the battery fluid come into direct contact with your skin.)
Using AC power
An AC adaptor (AD-5, optional) is required when using household current. Use
only genuine CASIO adaptor with the same voltage rating (100, 117, 220 or
240V) as the power supply in your area to prevent damage to internal compo-
nents. Be sure to turn the power of the unit off before you connect the adaptor to
the unit. Plug the AC adaptor into the AC outlet and the cord into the unit. This will
automatically cut off the battery power supply.
