F. Variable Resistors, Light-Emitting Diodes, and Check Pins byPCBOf the variable resistors (VR), light-emitting diodes (LED), and check pins found,those that may be used in the field are discussed:1. Some LEDs emit dim light because of leak current when OFF; this is a normalcondition and should be kept in mind.2.VRs that may be used in the field . . . . . . . . .VRs that must not be used in the field . . . . .Do not use VRs and check pins not given in the list; they are for the factory onlyand require special instruments and high precision.11-124CHAPTER 11 TROUBLESHOOTINGCOPYRIGHT © 1997 CANON INC.
