4.8 Variable Resistors (VR), Light-Emitting Diodes (LED), and

Check Pins

Of the VRs, LEDs, and switches found in the machine, those used in the machine are dis-

cussed.

1. Some of the LEDs emit dim light when they are off because of leakage

current; this is a normal condition, and must be kept in mind.

2. VRs that may be used in the field

VRs that must not be used in the field

Those VRs and check pins not discussed herein are for use at the factory

only, and must not be used in the field, as they require special tools and

high precision.
