PSR-E243/YPT-240 Owner’s Manual
Setting Up
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 Power Adaptor
1
Make sure that the power of the instrument is off
(display is blank, except for notation staff).
2
Connect the AC adaptor to the power supply jack.
3
Plug the AC adaptor into an AC outlet.
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 adaptor (page 38) only. Using the
wrong adaptor can result in damage to the instrument
or overheating.
• 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.
Even when the power switch is turned off, electricity is
still flowing to the product at the minimum level. When
you are not using the product for a long time, make
sure to unplug the power cord from the wall AC outlet.
• When using Ni-MH batteries, follow the instructions that
came with the batteries. Use only the specified charger
device when charging.
