Setting Up
Be sure to do the following operations BEFORE turning on the power.
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 environmen-
tally friendly than batteries and does not deplete
resources.
Using an AC Adaptor
Make sure that the [
] (Standby/On) switch is off, then
connect the AC adaptor in the order shown in the illustra-
tion.
Using Batteries
This instrument requires C size, Alkaline (LR14)/Manga-
nese (R14) batteries, or rechargeable nickel-metal hydride
batteries (rechargeable Ni-MH batteries). The Alkaline bat-
teries or rechargeable Ni-MH batteries are recommended
for this instrument, since other types may result in poorer
battery performance.
1
Make sure that the power of the instrument is off.
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.
• Use only the specified AC adaptor (page 54). 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 the order shown above in reverse when disconnecting
the AC adaptor/power cord.

WARNING
Plug

The shape of the plug differs
depending on your area.
CAUTION
NOTE
• 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.
• Make sure to set the battery type correctly (page 13).
• When battery power becomes too low for proper operation,
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.
• This instrument cannot charge the batteries. Use only an
appropriate 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.
