unplug the product and have it checked by qualified
personnel before operating it further.
• Always turn the product off when not in use.
Unplug the product from the wall outlet if you are not
going to use it for several days or more. To disconnect the
cord, pull it out by the plug. Never pull the cord itself.
• Do not overload wall outlets, extension cords, or
convenience receptacles beyond their capacity, since this
can result in fire or electric shock.
• Do not use attachments not recommended by the
manufacturer, as they may cause hazards.
• Do not touch the AC power adapter with wet hands. If
you fail to observe this, it may cause electric shock.

or shelf. The product may fall, causing serious injury to a
child or an adult, and serious damage to the product.
