1-2. Precautions for Part Replacement
• In the schematic diagram, parts marked (ex.
F801) are critical part to meet the safety regulations,
so always use the parts bearing specified part codes
(SN) when replacing them.
• Using the parts other than those specified shall
violate the regulations, and may cause troubles such
as operation failures, fire etc.
