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 (display is blank, except for nota-
tion staff).
2 Connect the AC power 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 the 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 batter-
ies 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 42). 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
batteries are installed in the instrument and the power is on.
Doing so will turn the power off.

NOTICE
• Make sure to install the batteries with the proper orientation,
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 complete set of
six new batteries. NEVER mix old and new batteries. Do not use
different kinds of batteries (e.g. alkaline and manganese) at the
same time.
• If the instrument is not to be in use for a long time, remove the
batteries from it, in order to prevent possible fluid leakage from
the battery.
• Use alkaline batteries for this instrument. Other types of bat-
teries (including rechargeable batteries) may have sudden
drops of power when battery power becomes low.
