6.8 Variable Resistors (VR), Light-Emitting Diodes (LED), and
Check Pins by PCB
Of the variable resistors (VR), light-emitting diodes (LED), and check pins used in the
CLC1000, those that are needed when servicing the machine in the field are discussed.
1 Do not touch the VRs and check pins that are not mentioned herein; they
are for factory use only and require special instruments and high preci-
sion for adjustment.
2 Some LEDs emit light because of leakage current; this is a normal con-
dition and must be kept in mind.
