Press down on Photo-chopper to release tension from mo-

tor mount.

8. Use the “+” button on the Vission 20/20 to drive the

capacity slide to its maximum mechanical stop position.

This will be apparent by a slowing of the motor rotation

and a winding sound from the actuator motor. When

you hear the motor wind-up, release the “+” button.

9. Quickly press and release the BLUE CALIBRATION

BUTTON on the ACTUATOR motor once. The RED LED

will stop ﬂ ashing. This now instructs the ACTUATOR mo-

tor that this point is the maximum slide position. This

point corresponds to 5 volts. The ACTUATOR calibration

procedure is completed.

Now the Capacity Channel is automatically calibrated

based on the calibration settings made to the actuator.

CAUTION

Do not over tigten screws. Failure to comply may

result in damage to equipment.

10. Gently lower the plastic cover to where it contacts

the base and O-ring seal. After making sure that the cov-

er is not binding, gently tighten the four screws.

11. Repeat the same procedure for the Volume slide

motor.
