Setting Up; Power Requirements - Yamaha PortaTone PSR-450 Owner's Manual

Setting Up

This section contains information about setting up your PSR-450 for playing. Make sure to
read this section carefully before using the instrument.

Power Requirements

Although the PSR-450 will run either from an 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.
■ Using an AC Power Adaptor
q Make sure that the [STANDBY/ON] switch of the PSR-450 is set to
STANDBY.
w Connect the AC adaptor (PA-5D, PA-5C or other adaptor specifically recom-
mended by Yamaha) to the power supply jack.
e Plug the AC adaptor into an AC outlet.
w
■ Using Batteries
For battery operation the PSR-450 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 Turn the instrument upside-down on the soft cloth, then open the battery com-
partment cover located on the instrument's bottom panel.
w Insert the six new batteries as shown in the illustration, making sure that the
positive and negative terminals are properly aligned.
e Replace the compartment cover, making sure that it locks firmly in place.

CAUTION
• Never interrupt the power
supply (e.g. remove the bat-
teries or unplug the AC adap-
tor) during any PSR-450
record operation! Doing so
can result in a loss of data.
WARNING
• Use ONLY a Yamaha PA-5D,
PA-5C 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-450.
• Unplug the AC Power Adap-
tor when not using the PSR-
450, or during electrical
storms.
CAUTION
• 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 bat-
tery.
• Use of a power adaptor is
recommended when per-
forming floppy disk opera-
tions. If you use batteries and
the batteries fail during an
operation, the PSR-450 and/
or floppy disk data can be
corrupted or lost.
