standard household power outlet.
WARNING
• Use only the included power adaptor (PA-3C or PA-
130) or an equivalent recommended by Yamaha).
Use of a different adaptor may result in equipment
damage, overheating, or fire. Doing so will also
immediately void the product warranty, even if the
effective warranty period has not expired.
•Wrap the DC output cable of the adaptor around
the cable clip (as shown below) to prevent acciden-
tal unplugging of the cable during operation. Avoid
tightening the cord more than necessary or pulling
on the cord strongly while it is wrapped around the
cable clip to prevent wear on the cord or possible
breakage of the clip.
