Setting Up

Power Requirements

Although the instrument will run either from an AC

adaptor or batteries, Yamaha recommends use of an

AC adaptor whenever possible. An AC adaptor is

more environmentally friendly than batteries and

does not deplete resources.

 Using an AC Adaptor

Connect the AC adaptor in the order shown in the

illustration.

WARNING

• Use the specified AC adaptor (page 24) only. Using the

wrong AC adaptor can result in damage to the instrument

or overheating.

WARNING

• When using the AC adaptor with a removable plug, make

sure to keep the plug attached to the AC adaptor. Using the

plug alone can cause electric shock or fire.

• If the plug is accidentally removed from the AC adaptor,

slide it back in until it clicks into place, taking care to

avoid touching any internal metal parts. To avoid electric

shock, short circuit or damage, also be careful that there

is no dust between the AC adaptor and plug.

The shape of the plug differs depending on

your area.

CAUTION

• When setting up the product, make sure that the AC outlet

you are using is easily accessible. If some trouble or mal-

function occurs, immediately turn the power off and dis-

connect the plug from the outlet.

NOTE

• Follow the order shown above in reverse when disconnecting

the AC adaptor.

 Using Batteries

This instrument requires six "AA" size, Alkaline (LR6)/

Manganese (R6) batteries, or rechargeable nickel-

metal hydride batteries (rechargeable Ni-MH batter-

ies). The Alkaline batteries or rechargeable Ni-MH

batteries are recommended for this instrument, since

other types may result in poorer battery performance.

WARNING

• When the batteries run out, or if the instrument is not to be

used for a long time, remove the batteries from the instru-

ment.

Make sure that the power of the instrument is off.

Open the battery compartment cover located on

the instrument's bottom panel.

Insert the six new batteries, being careful to fol-

low the polarity markings on the inside of the

compartment.

Replace the compartment cover, making sure

that it locks firmly in place.

Make sure to set the battery type correctly (page 11 ).

NOTICE

• Connecting or disconnecting the power adaptor with bat-

teries installed may turn the power off, resulting in loss of

data being recorded at the time.

• When battery power becomes too low for proper opera-

tion, the volume may be reduced, the sound may be dis-

torted, and other problems may occur. When this happens,

make sure to replace all batteries with new ones or already

recharged ones.
