PSR-E313/YPT-310 Owner’s Manual
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
q
Make sure that the power of the instrument is off
(the backlit display is off).
w
Connect the AC power adaptor to the power supply
jack.
e Plug the AC adaptor into an AC outlet.
■ Using Batteries
q
Open the battery compartment cover located on the
instrument’s bottom panel.
w Insert the six new alkaline batteries, being careful
to follow the polarity markings on the side of the
compartment.
e
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. (Alka-
line batteries are recommended.) When battery
power becomes too low for proper operation, the
volume may be reduced, the sound may be dis-
torted, and other problems may occur. When this
happens, make sure to replace all batteries, follow-
ing the precautions listed below.
If necessary, also make sure to save all important
User data (see page 31), since custom panel set-
tings are lost when the batteries are removed.
Power Requirements
• Use the specified adaptor (PA-130 or an equivalent
recommended by Yamaha) only. The use of other
adaptors may result in irreparable damage to both the
adaptor and the instrument.
WARNING
• 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, possibly resulting
in loss of the data being transferred and the data cur-
rently in the transfer destination during transferring or
recording a data.
CAUTION
• Use alkaline batteries for this instrument. Other types of
batteries (including rechargeable batteries) may have
sudden drops of power when battery power becomes low,
possibly resulting in loss of data in the flash memory.
• Make sure to install the batteries with the proper orienta-
tion, maintaining the correct polarity (as shown). Incor-
rect 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
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.
• Please use the power adaptor when transferring data to
flash memory. Batteries (including rechargeable types)
can be drained rapidly by this type of operation. If the bat-
teries do become drained during a data transfer, both the
data being transferred and the data currently in the trans-
fer destination will be lost.
