Connect the supplied power cord to the AC IN
on the instrument's rear panel.

CAUTION
Make sure your S90 XS/S70 XS meets the voltage requirement for the
country or region in which it is being used. The power cord includes a
grounding pin to prevent electrical shock and damage to equipment.
When connecting to an outlet, connect the adaptor's ground lead to
the ground screw. If you're unsure how to connect, then contact your
Yamaha dealer or service center (page 63).
WARNING
Use only the AC power cord supplied with the S90 XS/S70 XS. The
use of an inappropriate replacement can pose a fire and shock
hazard!
CAUTION
Even when the switch is in the OFF position, a small amount of
electricity is still flowing to the unit. When you are not using the S90
XS/S70 XS for a long time, make sure to unplug the AC power adaptor
from the wall AC outlet.
