Setting Up; Using An Ac Adaptor - Yamaha CK88 Owner's Manual

Setting up

Although the CK will run either from an AC adaptor or batteries, Yamaha recommends the use of an AC adaptor
whenever possible. An AC adaptor is more environmentally friendly than batteries and does not deplete resources.
NOTICE
It is recommended to use the AC adaptor when executing USB flash drive operations, since battery power may not be reliable
enough to last through these crucial operations.

Using an AC adaptor

Make sure that the [P] (Standby/On) switch is in a
standby position (the switch is up), then connect the
AC adaptor in the order shown in the illustration.
1.
Wrap the DC output cable of the AC adaptor
around the cord hook (as shown below),
and then connect the plug of the adaptor to
the DC IN jack on the rear panel.
NOTICE
Use of the cord hook prevents accidental unplugging of
the cable during operation. Make sure to avoid
tightening the cord more than necessary or pulling on
the cord strongly while it is wrapped around the cord
hook, in order to prevent wear on the cord or possible
breakage of the hook.
2.
Connect the other end of the AC adaptor to
an AC outlet.

WARNING
• Use the specified AC adaptor (page 69) only. Using the
wrong AC adaptor can result in damage to the instrument
or overheating.
• When using the AC adaptor with a removable plug, make
sure to keep the plug attached to the AC adaptor. Using
the plug alone can cause electric shock or fire.
• If the plug is accidentally removed from the AC adaptor,
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.
The shape of the plug differs depending on
your area.
CAUTION
When setting up the product, make sure that the AC outlet
you are using is easily accessible. If some trouble or
malfunction occurs, immediately turn the power off and
disconnect the plug from the outlet.
NOTE
• Follow the order shown above in reverse when disconnecting the
AC adaptor.
• When the AC adaptor is connected, the adaptor is used for
supplying power to the instrument regardless of whether or not
the batteries are installed to the instrument.
• Do not insert or remove the DC plug with the [P] (Standby/On)
switch set to the On position (O). Failure to observe this
precaution can lead to malfunction.
Plug
Slide the plug
as indicated.
