Setting Up
This section contains information about setting up your PSR-175/172 for playing. Make sure to
read this section carefully before using the instrument.
Power Requirements
Although the PSR-175/172 will run either from an optional AC adaptor or batter-
ies, Yamaha recommends use of an AC adaptor whenever possible. An AC adap-
tor is more environmentally friendly than batteries and does not deplete resources.
■ Using an AC Power Adaptor • • • • • • • • • • • • • • • • • • • • • • • • •
To connect your PSR-175/172 to a wall socket, you will need the optionally avail-
able 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-175/172 is set to
STANDBY.
Connect one end of the adaptor to the DC IN 12V jack on the rear panel of your
PSR-175/172, and the other end to a suitable electrical outlet.
■ Using Batteries • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • • •
● 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-175/172 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-175/172.
• Unplug the AC Power Adaptor
when not using the PSR-175/
172, 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-175/172 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.
