Risk of electric shocks. Before performing any maintenance or servicing, always disconnect the unit from its power

source. This product employs overload protection (fuse). A blown fuse indicates an overload or short-circuit situation.

If the fuse blows, unplug the product from the outlet. Replace the fuse as per the servicing instructions (follow

product marking for proper fuse rating) and check the product. If the replacement fuse blows, a short-circuit may be

present and the product should be discarded or returned to an authorized service facility for examination and/or repair.
