Setting Up
This section contains information about setting up your PSR-540 and preparing to play.
Be sure to go through this section carefully before turning the power on.
CAUTION
• Never interrupt the power
supply (e.g. remove the
batteries or unplug the AC
adaptor) during any PSR-
540 record operation!
Doing so can result in a
loss of data.
Power supply connections
Although the PSR-540 will run either from an optional AC adaptor or batteries,
Yamaha recommends use of the more environmentally safe AC adaptor. Follow the
instructions below according to the power source you intend to use.
■ Using An Optional AC Power Adaptor
1
Make sure that the STANDBY/ON switch of the
PSR-540 is set to STANDBY.
WARNING
• Use ONLY a Yamaha PA-6
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-540.
• Unplug the AC Power
Adaptor when not using
the PSR-540, or during
electrical storms.
■ Using Batteries
For battery operation the PSR-540 requires six 1.5V SUM-1, “D” size, R-20 or equiva-
lent batteries. When the batteries need to be replaced, “Battery Low” may appear on
top of the display, 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.
Replace the batteries as follows:
CAUTION
• When the batteries run
down, replace them with a
complete set of six new
batteries. 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.
• Plugging or unplugging
the AC power adaptor
while the batteries are
installed will reset the
PSR-540 to the defaults.
3
Plug the AC adaptor into an AC outlet.
When turning the power OFF, simply reverse the
procedure.
1
Open the battery compartment cover located on the instrument’s bottom panel.
2
Insert the six new batteries, being careful to follow the polarity markings on the
inside of the compartment.
3
Replace the compartment cover, making sure that it locks firmly in place.
2
Connect the AC adaptor (PA-6 or other adaptor
specifically recommended by Yamaha) to the
power supply jack.
