SETTING UP This section contains information about setting up your PortaTone for playing. Make sure to read this section carefully before using the instrument. POWER REQUIREMENTS Although the PSR-225 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. Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-225 record operation! Doing so can result in a loss of data. Using an AC Power Adaptor To connect your PortaTone 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 PortaTone, and the other end to a suitable electrical outlet. Using Batteries I Inserting Batteries Turn the instrument upside-down and remove the battery compartment lid. Insert six 1.5-volt size "D", R20P (LR20) or equivalent batteries as indicated in the battery case, making sure that the positive and negative terminals are properly aligned, and replace the lid. I When the Batteries Run Down When the batteries run low and the battery voltage drops below a certain level, the PortaTone may not sound or function properly. As soon as this happens, replace them with a complete set of six new batteries. • Never mix old and new batteries or different types of batteries (e.g., alkaline and manganese). • To prevent possible damage from battery leakage, remove the batteries from the instrument if it is not to be used for a long time. • 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 PSR225. • Unplug the AC Power Adaptor when not using the PSR-225, or during electrical storms. 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.) Even when the switch is in the "STANDBY" position, electricity is still flowing to the instrument at the minimum level. When you are not using the PSR-225 for a long time, make sure you unplug the AC power adaptor from the wall AC outlet, and/or remove the batteries from the instrument. 8

SETTING UP
This section contains information about setting up your PortaTone for playing.
Make sure to read this section carefully before using the instrument.
Using Batteries
■
Inserting Batteries
Turn the instrument upside-down and remove
the battery compartment lid.
Insert six 1.5-volt
size “D”, R20P (LR20) or equivalent batteries as
indicated in the battery case, 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
PortaTone may not sound or function properly.
As soon as this happens, replace them with a
complete set of six new batteries.
• Never mix old and new batteries or different types of
batteries (e.g., alkaline and manganese).
• To prevent possible damage from battery leakage, remove
the batteries from the instrument if it is not to be used for a
long time.
POWER REQUIREMENTS
Although the PSR-225 will run either from an
optional AC adaptor or batteries, Yamaha rec-
ommends use of an AC adaptor whenever
possible.
An AC adaptor is more environmen-
tally friendly than batteries and does not deplete
resources.
Never interrupt the power supply (e.g. remove the batteries or
unplug the AC adaptor) during any PSR-225 record operation!
Doing so can result in a loss of data.
Using an AC Power Adaptor
To connect your PortaTone 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 PortaTone, and the other end to a
suitable electrical outlet.
• 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 PSR-
225.
• Unplug the AC Power Adaptor when not using the PSR-225,
or during electrical storms.
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.)
Even when the switch is in the “STANDBY” position, electricity
is still flowing to the instrument at the minimum level. When
you are not using the PSR-225 for a long time, make sure you
unplug the AC power adaptor from the wall AC outlet, and/or
remove the batteries from the instrument.
