Introduction
Setting Up
Be sure to do the following operations BEFORE turning on the power.
Although the instrument will run either from an optional 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 Power Adaptor
1
Make sure that the [
] (Standby/On) switch of
the instrument is off (the power indicator located to
the left of the switch is off).
2
Connect the AC adaptor to the power supply jack.
3
Plug the AC adaptor into an AC outlet.
Using Batteries
1
Open the battery compartment cover located on the
instrument’s bottom panel.
2
Insert six new alkaline batteries, being careful to
follow the polarity markings on the side of the
compartment.
3
Replace the compartment cover, making sure that it
locks firmly in place.
For battery operation, the instrument requires six 1.5V
“AA” size, LR6 or equivalent batteries. (Alkaline bat-
teries are recommended.) 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, following the precautions listed
below.
Power Requirements
• Use the specified adaptor (page 22). The use of other
adaptors may result in irreparable damage to both the
adaptor and the instrument.
• Unplug the AC Power Adaptor when not using the
instrument, or during electrical storms.
• Never connect or disconnect the AC power adaptor when the power is on
and the batteries are installed. Doing so will turn the power off.

NOTE
• Make sure to install the batteries with the proper orienta-
tion, maintaining the correct polarity (as shown). Incorrect
battery installation may result in heat, fire and/or leaking of
corrosive chemicals.
• When the batteries run down, replace them with a com-
plete set of six new batteries. NEVER mix old and new bat-
teries. Do not use different kinds of batteries (e.g. alkaline
and manganese) at the same time.
• If the instrument is not to be used for a long time, remove
the batteries in order to prevent possible fluid leakage and
damage to the instrument.
