Setting Up
This section contains information about setting up your PSR-730/630 and preparing to play.
Be sure to go through this section carefully before using your PSR-730/630.
Power Supply
Although the PSR-730/630 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.
• Never interrupt the power
supply (e.g. remove the
batteries or unplug the
AC adaptor) during any
PSR-730/630 record op-
eration! Doing so can re-
sult in a loss of data.
■Using An Optional AC Power Adaptor
zPlug an optional Yamaha PA-6 Power Adaptor into a wall AC outlet.
xThen plug the DC output cable from the PA-6 into the DC IN 10-12V jack on
the rear panel of the PSR-730/630. The internal batteries are automatically
disconnected when an AC Power Adaptor is used.
• Use ONLY a Yamaha PA-6 AC
Power Adaptor (or other
adaptor specifically recom-
mended by Yamaha) to power
your instrument from the AC
mains. The use of other adap-
tors may result in irreparable
damage to both the adaptor
and the PSR-730/630.
• Unplug the AC Power Adap-
tor when not using the PSR-
730/630, or during electrical
storms.
■Using Batteries
For battery operation the PSR-730/630 requires six 1.5V SUM-1, “D” size, R-
20 or equivalent batteries.
When the batteries need to be replaced “Lo Battery!!” 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:
zOpen the battery compartment cover located on the instrument’s bottom panel.
xInsert the six new batteries, being careful to follow the polarity markings on
the inside of the compartment.
cReplace the compartment cover, making sure that it locks firmly in place.
DC IN 10-12V
PA-6
• 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 pos-
sible fluid leakage from
the battery.
• Plugging or unplugging
the AC power adaptor
while the batteries are in-
stalled will reset the PSR-
730/630 to the defaults.
When turning the power OFF, simply reverse the procedure.
◆Important Notes on Battery Use
• Since the PSR-730 and PSR-630 consume a considerable
amount of power, Yamaha recommends the use of an AC po wer
adaptor rather than batteries. The batteries should be consid-
ered 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 re-
cording/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-630/730 for an impor-
tant performance or when creating important data.
• When using batteries and the “Lo Battery!!” warning initially
appears on the display, the volume will drop a little but you will
be able to use the instrument for a while longer. When the “Lo
Battery!!” warning begins to appear every few seconds, re-
place the batteries as soon as possible.
