6.1.6 Variable Resistors(VR), LED, and Check Pins by PCB
6.1.6.1 Variable Resistors (VR), Test Pins, Jumpers, and Switches
0008-1749
This section lists only the variable resistors (VR), LEDs, test pins, jumpers, and switches required for after-sales service in the field.
All other VRs, 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
precision. Do not touch them in the field.
