Setting Up

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 environmentally friendly than batteries and
does not deplete resources.

Using an AC adaptor

1
Make sure that the power of the instrument is off
(the backlight display is off).
WARNING
• Use the specified adaptor (page 42) only. Using the
wrong adaptor can result in damage to the instrument
or overheating.
• See "For the AC adaptor with a Removable Plug" (page
46).
2
Connect the AC adaptor to the DC IN jack (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.

NOTE
• After turning off the power, follow this procedure in reverse
order to disconnect the AC adaptor.
• Power will be automatically drawn from the AC adaptor if an
AC adaptor is connected while batteries are installed in the
instrument.

Using Batteries

This instrument requires six "AA" size, Alkaline (LR6)/
Manganese (R6) batteries, or rechargeable nickel-
metal hydride batteries (rechargeable Ni-MH batter-
ies). The Alkaline batteries or rechargeable Ni-MH
batteries are recommended for this instrument, since
other types may result in poorer battery performance.

 Installing the batteries
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.
NOTICE
• Connecting or disconnecting the AC adaptor with batteries
installed may turn the power off, resulting in loss of data
being recorded or transferred at the time.
• Change the setting of the instrument according to the kind
of battery you are using (Battery Type; page 42).
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 batter-
ies 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.
