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 Adaptor
Connect the AC adaptor in the order shown in the
illustration.
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.
 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.
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.
• Use the specified AC adaptor (page 61) only. Using the
wrong AC adaptor can result in damage to the instrument
or overheating.
• 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.
• Never touch the metallic section when attaching the plug.
To avoid electric shock, short circuit or damage, also be
careful that there is no dust between the AC adaptor and
plug.
• 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.
• Follow this procedure in reverse order when disconnecting
the AC adaptor.

installed may turn the power off, resulting in loss of data
being recorded or transferred at the time.
• 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.
