Variable Resistors, Light-Emitting Diodes, And Check Pins By Pcb - Canon NP6330 Service Handbook

CHAPTER 3 ARRANGEMENT/FUNCTIONS OF THE ELECTRICAL PARTS
F. Variable Resistors, Light-Emitting Diodes, and Check Pins by
PCB
Of the variable resistors (VR), light-emitting diodes (LED), and check pins found,
those that may be used in the field are discussed:
Note:
1. Some LEDs emit dim light because of leak current when OFF; this is a normal
condition and should be kept in mind.
2.VRs that may be used in the field . . . . . . . . .
VRs that must not be used in the field . . . . .
Note:
Do not use VRs and check pins not given in the list; they are for the factory only
and require special instruments and high precision.
