Power Requirements - Yamaha PSR-F50 Owner's Manual

Power Requirements

Although the instrument 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
1 Make sure that the power of the instrument is off.
WARNING
• Use the specified adaptor (refer to "Specifications" on
page 9). Using the wrong adaptor can result in dam-
age to the instrument or overheating.
2 Connect the AC adaptor to the power supply jack.
3 Plug the AC adaptor into an AC outlet.

CAUTION
• When using a power adaptor, even when the power is
off, a small amount of electricity is still being con-
sumed by the instrument. When you are not using the
instrument for a long time, make sure to unplug the
AC power adaptor from the wall AC outlet.
 Notice for the AC adaptor
Depending on your particular locale, the AC adaptor
having a separable plug should be used. In this case,
make sure to follow the explanations below for your
safety.
If the plug is accidentally removed from the AC
adaptor
Without touching the metallic section, slide the plug
into place as shown below then push it in completely
until you hear the click sound.

WARNING
• Make sure to keep the plug attached to the AC adaptor.
Using the plug alone can cause electric shock or fire.
• Never touch the metallic section when attaching the plug.
To avoid electric shock, short circuit or damage, also be
careful that there is no dust between the AC adaptor and
plug.
Using Batteries
WARNING
• See the "Battery" section in the Precautions.
 Installing the batteries
1 Make sure that the power of the instrument is off.
2 Open the battery compartment cover located on
the instrument's bottom panel.
3 Insert six new 1.5V "AA" size alkaline batteries
or 1.2V rechargeable Ni-MH batteries (recom-
mended), being careful to follow the polarity
markings on the inside of the compartment.
4 Replace the compartment cover, making sure that
it locks firmly in place.
