• Risk of electric shocks. Before performing any maintenance or servicing, always disconnect the unit from its power source.
• This product is equipped with an overload protection (fuse). A blown fuse indicates an overload or a short-circuit situation.
If the fuse blows, unplug the product and check the polarity and voltage output from the outlet. Replace the fuse as per the
servicing instructions (refer to wiring diagram for proper fuse rating) and verify the product. If the replaced fuse blows, it may
be a short-circuit and the product must be discarded or returned to an authorized service center for examination and/or repair.
