14.3.8 Variable Resistors (VR), Light-Emitting Diodes (LED), and Check Pins by PCB

14.3.8.1 Variable Resistors (VR), Light-Emitting Diodes, and Check Pins by PCB
iR2270 / iR2870 / iR3570 / iR4570 / / iR2270N / / iR2870N / / iR3570N / / iR4570N / iR2230 / / / iR3530 /
Of the variable resistors (VR), light-emitting diodes (LED), and check pins found in the machine, those that are needed when servicing the machine in the field are
discussed.
- Some LEDs carry current and emit light when they are off; this is a normal condition, and must be kept in mind.
- Take note of the following:
...VR that may be used in the field.
...VR that must not be used in the field.
14.3.8.2 Points to Note About the Leakage Breaker

Points to Note When Checking the Output of a PCB
Normally, an AC voltage is applied to the terminal of the leakage breaker [1].
Take care not to touch it when making a check.
