Setting Up

Power Requirements

This instrument can be operated either from an AC adaptor or batteries. Yamaha recommends use of an AC adaptor
whenever possible, since an AC adaptor is more environmentally friendly than batteries and does not deplete resources.
NOTICE
You should use an AC adaptor when using a USB flash memory drive. Using battery power could cause the power to go out
during operation, resulting in data loss.
Using an AC Adaptor
Connect the AC adaptor in the order shown in the illustration.
WARNING
• Only use the specified AC adaptor (page 40). Using the wrong AC adaptor can result in
damage to the instrument, overheating, or fire accidents. Note that an accident caused
by incorrect usage may void the warranty even if the instrument is still within the
warranty period.
• When using an AC adaptor with a removable plug, make sure to keep the plug attached
to the AC adaptor during use or storage. Inserting the plug alone into the AC outlet can
cause electric shock or fire.
• If the plug is accidentally removed from the AC adaptor, insert the plug all the way in
until you hear a click, taking care to avoid touching any internal metal parts. To avoid electric shock, short circuit, or damage
to the instrument, also be careful that there is no dust between the AC adaptor and plug.
CAUTION
When setting up the product, make sure that the power outlet you are using is easily accessible. If some trouble or malfunction
occurs, immediately turn the power off and disconnect the plug from the outlet.
NOTICE
Hook the cable of the AC adaptor on the cord hook to prevent damage to the cable.
NOTE
To remove the AC adaptor, turn the power off first, and then follow the above instructions in reverse order.
