NEVER mix old and new batteries. • Do not use different kinds of batteries (e.g. alkaline and manganese) at the same time. • If the instrument is not to be in use for a long time, remove the batteries from it, in order to prevent possible fluid leakage from the battery. 10

Setting Up
This section contains information about setting up your PSR-290 for playing.
Make sure to
read this section carefully before using the instrument.
Although the PSR-290 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.

Make sure that the [STANDBY/ON] switch of the PSR-290 is set to
STANDBY.

mended by Yamaha) to the power supply jack.

For battery operation the PSR-290 requires six 1.5V “D” size, R20P (LR20) or
equivalent batteries. (Alkaline batteries are recommended.)
When the batteries
need to be replaced, the volume may be reduced, the sound may be distorted, and
other problems may occur. When this happens, turn the power off and replace the
batteries, as described below
q
Open the battery compartment cover located on the instrument’s bottom panel.
w
Insert the six new batteries, being careful to follow the polarity markings on
the inside of the compartment.
e
Replace the compartment cover, making sure that it locks firmly in place.
Power Requirements
• Never interrupt the power sup-
ply (e.g. remove the batteries
or unplug the AC adaptor) dur-
ing any PSR-290 record opera-
tion! Doing so can result in a
loss of data.
• Never attempt to turn the
power off when a “WRITING!”
message is shown in the dis-
play. Doing so can damage the
internal flash memory and
result in loss of data.
• 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-290.
• Unplug the AC Power Adaptor
when not using the PSR-290,
or during electrical storms.
w
e
• When the batteries run down,
replace them with a complete
set of six new batteries.
NEVER mix old and new bat-
teries.
• Do not use different kinds of
batteries (e.g. alkaline and
manganese) at the same time.
• If the instrument is not to be in
use for a long time, remove the
batteries from it, in order to
prevent possible fluid leakage
from the battery.
