8 PSR-E203/YPT-200 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
(display is blank, except for notation staff).
w Connect the AC adaptor (PA-3B, PA-3C or other
adaptor specifically recommended by Yamaha) 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.
Power Requirements
• Use ONLY a Yamaha PA-3B or PA-3C AC Power Adap-
tor (or other adaptor specifically recommended by
Yamaha) to power your instrument from the AC mains.
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.

e
•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.
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.
• 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.
