10. Servicing - Refer all servicing to qualified service personnel. Servicing is required when the device has been damaged
in any way, such as the power-supply cord or plug is damaged, liquid has been spilled, objects have fallen into the
device, the device has been exposed to rain or moisture, does not operate normally or has been dropped.
11. Damage requiring service - If any of the following conditions occurs, unplug the power cord
from the AC outlet and request a qualified service technician to perform repairs.
a. When the power cord or plug is damaged.
b. When liquid is spilled on the product or when objects have fallen into the product.
c. When the product has been exposed to rain or water.
d. When the product does not operate properly as described in the operating instructions.
Do not touch the controls other than those described in the operating instructions. Improper adjustment of controls not described in
the instructions can cause damage, which often requires extensive adjustment work by a qualified technician.
e. If the product has been dropped or the cabinet has been damaged in any way.
f. When the product displays an abnormal condition or exhibits a distinct change in performance.
