Important Notes on Battery Use • Since the PSR-540 consume a considerable amount of power, Yamaha recommends the use of an AC power adaptor rather than batteries. The batteries should be considered an auxiliary power source for data backup. • The floppy disk drive, in particular, uses a large amount of power, so it is important to always use an AC power adaptor when performing disk-intensive operations such as song recording/playback or data load/save. If you attempt to use battery power for these operations and the batteries do fail, you will lose not only the data you're recording or saving, but also other data in internal memory including user styles, user pads, registration memory, etc. • Taking the above precautions into consideration, always use an AC power adaptor when using the PSR-540 for an important performance or when creating important data. Setting Up Connecting a footswitch s FOOT SWITCH jack The sustain function lets you produce a natural sustain as you play by pressing a footswitch. Plug an optional Yamaha FC4 or FC5 footswitch into this jack and use it to switch sustain on and off. The footswitch connected to this jack can also be set to replicate the functions of some panel buttons, doing things like starting and stopping accompaniment (page 121). • Be sure that you do not press the footswitch while turning the power on. If you do, the ON/OFF status of the footswitch will be reversed. • When the sustain or sostenuto pedal functions are being used (page 121), some voices may sound continuously or have a long decay after the notes have been released while the pedal is held. Audio equipment connections s PHONES/OUTPUT jack A standard pair of stereo headphones can be plugged in here for private practice or late-night playing. The internal stereo speaker system is automatically shut off when a pair of head phones is plugged into the PHONES/OUTPUT jack. Do not listen with the headphones at high volume for long periods of time. Doing so may cause hearing loss. CAUTION • Connect the PSR-540 to external equipment only after turning off power for all devices. 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. 13 11

Important Notes on Battery Use
•
Since the PSR-540 consume a considerable amount of power, Yamaha recommends the use of an AC power
adaptor rather than batteries. The batteries should be considered an auxiliary power source for data backup.
•
The floppy disk drive, in particular, uses a large amount of power, so it is important to always use an AC
power adaptor when performing disk-intensive operations such as song recording/playback or data load/save.
If you attempt to use battery power for these operations and the batteries do fail, you will lose not only the
data you’re recording or saving, but also other data in internal memory including user styles, user pads,
registration memory, etc.
•
Taking the above precautions into consideration, always use an AC power adaptor when using the PSR-540
for an important performance or when creating important data.
Connecting a footswitch
■
FOOT SWITCH jack
The sustain function lets you produce a natural sustain as you play by pressing a
footswitch. Plug an optional Yamaha FC4 or FC5 footswitch into this jack and use it to
switch sustain on and off. The footswitch connected to this jack can also be set to
replicate the functions of some panel buttons, doing things like starting and stopping
accompaniment (page 121).
•
Be sure that you do not
press the footswitch while
turning the power on. If you
do, the ON/OFF status of the
footswitch will be reversed.
•
When the sustain or
sostenuto pedal functions
are being used (page 121),
some voices may sound
continuously or have a long
decay after the notes have
been released while the
pedal is held.
Audio equipment connections
■
PHONES/OUTPUT jack
A standard pair of stereo headphones can be plugged in here for private practice or
late-night playing. The internal stereo speaker system is automatically shut off when a
pair of head phones is plugged into the PHONES/OUTPUT jack.
Do not listen with the headphones at high volume for long periods of time. Doing so
may cause hearing loss.
CAUTION
•
Connect the PSR-540 to
external equipment only
after turning off power for
all devices. 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.
