This section contains useful information about setting up your YPR-50 for playing. Make sure to read this
section carefully before using the instrument.
Power Requirements
Although the YPR-50 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 YPR-50 to a wall socket, you will
need the optionally available Yamaha 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. Connect one end of the adaptor to the
DC IN 10-12V jack on the rear panel of your YPR-
50, and the other end to a suitable electrical outlet.
WARNING
Use ONLY a Yamaha PA-3B AC Power Adaptor (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 YPR-50.
CAUTION
Unplug the AC Power Adaptor when not using the
YPR-50, or during electrical storms.
Using Batteries
Inserting Batteries
Turn the instrument upside-down and remove the
battery compartment lid. Insert six 1.5-volt size
"D" (SUM-1, R-20 or equivalent) batteries as
shown in the illustration, 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 YPR-50
may not sound or function properly. As soon as
this happens, replace them with a complete set of
six new batteries.
CAUTION
Never mix old and new batteries or different types of
batteries (e.g., alkaline and manganese).
CAUTION
To prevent possible damage from battery leakage,
remove the batteries from the instrument if it is not
to be used for a long time.
Accessory Jacks
Using Headphones
For private practicing and playing without
disturbing others, connect a set of stereo
headphones to the rear panel PHONES/OUTPUT
jack. Sound from the built-in speaker system is
automatically cut off when you insert a headphone
plug into this jack.
Connecting a Keyboard Amplifier or
Stereo System
Though the YPR-50 is equipped with a built-in
speaker system, you can also play it through an
external amplifier/speaker system. First, make sure
the YPR-50 and any external devices are turned off,
then connect one end of a stereo audio cable to the
LINE IN or AUX IN jack(s) of the other device and
the other end to the rear panel PHONES/OUTPUT
jack on the YPR-50.
CAUTION
To prevent damage to the speakers, set the volume of
the external devices at the minimum setting before
connecting them. Failure to observe these cautions
may result in electric shock or equipment damage.
Also, be sure to set the volumes of all devices at their
minimum levels and gradually raise the volume
controls while playing the instrument to set the
desired listening level.
