Setting Up This section contains information about setting up your PSR-550 and preparing to play. Be sure to go through this section carefully before turning the power on. Power supply connections Although the PSR-550 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. CAUTION s Using An Optional AC Power Adaptor 1 Make sure that the STANDBY/ON switch of the PSR-550 is set to STANDBY. • Never interrupt the power supply (e.g. remove the batteries or unplug the AC adaptor) during any PSR-550 record operation! Doing so can result in a loss of data. 2 Connect the AC adaptor (PA-6 or other adaptor specifically recommended by Yamaha) to the power supply jack. 3 Plug the AC adaptor into an AC outlet. When turning the power OFF, simply reverse the procedure. 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-550. • Unplug the AC Power Adaptor when not using the PSR-550, or during electrical storms. s Using Batteries For battery operation the PSR-550 requires six 1.5V "D" size, R20P (LR20) or equivalent 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: 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. 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-550 to the defaults. Important Notes on Battery Use • Since the PSR-550 consumes 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. 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. • 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 • Taking the above precautions into consideration, always use an AC power adaptor when using the PSR-550 for an important performance or when creating important data. 12 10

Setting Up
This section contains information about setting up your PSR-550 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-550
record operation! Doing so
can result in a loss of data.
Power supply connections
Although the PSR-550 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
WARNING
•
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
adaptors may result in
irreparable damage to both
the adaptor and the PSR-550.
•
Unplug the AC Power Adaptor
when not using the PSR-550,
or during electrical storms.
■
Using Batteries
For battery operation the PSR-550 requires six 1.5V “D” size, R20P (LR20) or
equivalent 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-550 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.
1
Make sure that the STANDBY/ON switch
of the PSR-550 is set to STANDBY.
2
Connect the AC adaptor (PA-6 or other
adaptor specifically recommended by
Yamaha) to the power supply jack.
Important Notes on Battery Use
•
Since the PSR-550 consumes 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-550 for an important perfor-
mance or when creating important data.
