Setting Up

Power Requirements

Although the instrument will run either from an

optional AC adaptor or batteries, Yamaha recom-

mends use of an AC adaptor whenever possible. An

AC adaptor is more environmentally friendly than bat-

teries and does not deplete resources.

Using an AC Power Adaptor

1 Make sure that the power of the instrument is off

(display is blank, except for notation staff).

WARNING

• Use the specified adaptor (page 38) only. Using the

wrong adaptor can result in damage to the instrument

or overheating.

2 Connect the AC adaptor to the power supply jack.

3 Plug the AC adaptor into an AC outlet.

CAUTION

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

outlet you are using is easily accessible. If some trou-

ble or malfunction occurs, immediately turn off the

power switch and disconnect the plug from the outlet.

Even when the power switch is turned off, electricity is

still flowing to the product at the minimum level. When

you are not using the product for a long time, make

sure to unplug the power cord from the wall AC outlet.

Using Batteries

This instrument requires six "AA" size, Alkaline

(LR6)/Manganese (R6) batteries, or rechargeable

nickel-metal hydride batteries (rechargeable Ni-MH

batteries). The Alkaline batteries or rechargeable Ni-

MH batteries are recommended for this instrument,

since other types may result in poorer battery perfor-

mance.

WARNING

• When using Ni-MH batteries, follow the instructions that

came with the batteries. Use only the specified charger

device when charging.

 Installing the batteries

1 Make sure that the power of the instrument is off

(display is blank, except for notation staff).

2 Open the battery compartment cover located on the

instrument's bottom panel.

3 Insert the six new batteries, being careful to follow

the polarity markings on the inside of the compart-

ment.

4 Replace the compartment cover, making sure that it

locks firmly in place.

NOTICE

• Connecting or disconnecting the power adaptor with bat-

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

data being recorded or transferred at the time.

When battery power becomes too low for proper oper-

ation, the volume may be reduced, the sound may be

distorted, and other problems may occur. When this

happens, make sure to replace all batteries with new

ones or already-recharged ones.

NOTE

• This instrument cannot charge the batteries. Use only the

specified charger device when charging.

• Power will be automatically drawn from the AC adaptor if an

AC adaptor is connected while batteries are installed in the

instrument.
