iv
total rating of all products plugged into the wall outlet does not exceed
15 amperes.
11. Never push objects of any kind into this product through cabinet slots
as they may touch dangerous voltage points or short out parts that
could result in a fire or electric shock. Never spill liquid of any kind
on the product.
12. Do not attempt to service this product yourself, as opening or removing
covers may expose you to dangerous voltage points or other risks.
Refer all servicing to qualified service personnel.
13. Unplug this product from the wall outlet and refer servicing to
qualified service personnel under the following conditions:
a. When the power cord or plug is damaged or frayed
b. If liquid has been spilled into the product
