8. BIT-DRIVER SENSITIVITY ADJUSTMENT
In order to adjust the bit-driver, you must remove the black metal cover, then connect the fiber
optic cable in reverse of normal operations at one end only. ("Cable Setting" Illustration below)
1) Turn the blue sensitivity potentiometer counterclockwise until the RD diode on the front
panel lights up. (see diagram below) If RD is already on, go to step 2.
2) Turn the same potentiometer clockwise until the RD diode turns off.
