5. PART CONFIGURATION AND THEIR SYMBOLS
5-1. 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.
