age the components inside the unit.

specifications of the adapter must be: 9~12V DC output, 1800MA, centre positive
type.

Using batteries

Always make sure you turn the keyboard off before inserting new batteries or replac-
ing old ones.

To insert the batteries

1. Carefully turn the instrument upside-down and remove the battery com-
partment cover.
2. Insert six D size (SUM-1 or R-20) batteries into the battery compart-
ment, being careful to follow the polarity markings on the cabinet.
3. Replace the compartment cover, making sure that it locks firmly in place,
then turn the instrument the right way up.
