Setting Up
This section contains information about setting up your PSR-202 for playing. Make sure to
read this section carefully before using the instrument.

Power Requirements

Although the PSR-202 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 • • • • • • • • • • • • • • • • • • • • • • • • •

To connect your PSR-202 to a wall socket, you will need the optionally available
Yamaha PA-3C or PA-3B Power Adaptor. Use of other AC adaptors could result
in damage to the instrument, so be sure to ask for the right kind.
Make sure that the [STANDBY/ON] switch of the PSR-202 is set to STANDBY.
Connect one end of the adaptor to the DC IN 12V jack on the rear panel of your
PSR-202, and the other end to a suitable electrical outlet.

● Inserting Batteries
Turn the instrument upside-down and remove the battery compartment lid. Insert
six 1.5-volt “D” size, R20P (LR20) or equivalent batteries as shown in the illustra-
tion, making sure that the positive and negative terminals are properly aligned,
and replace the lid.
● When the Batteries Run Down
When the batteries run low and the battery voltage drops below a certain level, the
PSR-202 may not sound or function properly. As soon as this happens, replace
them with a complete set of six new batteries.

Turning On the Power

With the AC power adaptor connected or with batteries installed, simply move the
STANDBY switch until it is set to the ON position. When the instrument is not in
use, be sure to turn the power off.
• Use ONLY a Yamaha PA-3C or
PA-3B AC Power Adaptor (or
other adaptor specifically rec-
ommended by Yamaha) to
power your instrument from
the AC mains. The use of other
adaptors may result in irrepa-
rable damage to both the adap
-
tor and the PSR-202.
• Unplug the AC Power Adaptor
when not using the PSR-202,
or during electrical storms.
• Never mix old and new batter-
ies or different types of batter-
ies (e.g., alkaline and
manganese).
• To prevent possible damage
from battery leakage, remove
the batteries from the instru-
ment if it is not to be used for a
long time.
• Even when the switch is in the
“STANDBY” position, electric-
ity is still flowing to the instru-
ment at the minimum level.
When you are not using the
PSR-202 for a long time, make
sure you unplug the AC power
adaptor from the wall AC out-
let, and/or remove the batteries
from the instrument.
