Setting Up
This section contains information about setting up your PSR-350 for playing. Make sure to
read this section carefully before using the instrument.

Power Requirements

Although the PSR-350 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-350 to a wall socket, you will need the optionally available
Yamaha PA-5C 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-350 is set to STANDBY.
Connect one end of the adaptor to the DC IN 12V jack on the rear panel of your
PSR-350, 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-350 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 press the
power switch until it locks in the ON position. When the instrument is not in use,
be sure to turn the power off. (Press the switch again so that it pops up.)
• Never interrupt the power sup-
ply (e.g. remove the batteries
or unplug the AC adaptor) dur-
ing any PSR-350 record opera-
tion! Doing so can result in a
loss of data.
• Use ONLY a Yamaha PA-5C AC
Power Adaptor (or other adap-
tor 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 PSR-
350.
• Unplug the AC Power Adaptor
when not using the PSR-350,
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-350 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.
