Chapter 1 - Introduction

The lower Red, Green and Blue assignable rotary controls vary either:

– the skin contour colour width.
The function selected for adjustment and its value is shown in the menu display and the

This three-in-one control is used to vary the master black level, to control the iris and to
preview the connected camera signal on a preview monitor.
Operation
– Press the top of the knob to get a preview of the connected camera signal.
– Turn the lower knob to vary the master black level.
– Move the joystick up and down to open and close the iris. The joystick direction, range

Tension adjustment
When the joystick’s movement becomes too loose or too tight it may be necessary to adjust its
tension spring. Use a long Torx-10 type screwdriver to adjust the tension screw of the joystick.
The screw is located in a hole at the side panel of the OCP casing. Turn the screw and move
the joystick at the same time to find the right adjustment.
