C. Variable Resistors, LEDs, Test Pins, Jumpers and Switches on PCBs

Only the variable resistors, LEDs, test pins, jumpers, and switches required for after-sales ser-

vice in the field are listed below.

All other variable resistors, test pins, etc. are for the factory use only. The adjustment and

check using these test pins, etc. require special tools, measuring instruments and high preci-

sion. Do not touch them in the field.

Notes: 1. Some LEDs receive leakage current during normal operation, thus glow dimly even

when they should be OFF.

2. Variable resistor which may be adjusted in the field are marked .........

Variable resistor which may not be adjusted in the field are marked ...
