LENS SETUP PROCEDURES
For manual or fixed iris lenses set the EI switch to ON.
Auto Iris Lenses
Switch the EI off. Refer to the lens instructions and adjust the lens for the optimum picture
(video output level of 1V peak-to-peak).
Direct Drive Lenses
Switch the EI off. Use an appropriate screwdriver to turn the lens level potentiometer (under
the hinged flap) fully clockwise then back off until the optimum picture is obtained (video output
level of 1V peak-to-peak).
FOCUS ADJUSTMENT
The back focus adjustment screws are located on the top and side of the case and should be
adjusted using an appropriate screwdriver. If possible, always use the top screw to adjust the
back focus mechanism.
Turn the adjuster screw clockwise or anticlockwise to obtain focus. When the focus is sharp,
turn the back focus adjustment screw 2 or 3 turns anticlockwise. The picture will lose sharpness.
Turn the back focus screw clockwise until focus is once again obtained. If you have turned the
back focus screw clockwise past the point of best focus, repeat the procedure. The last turn
of the back focus adjustment screw must always be in a clockwise direction. Do not
over turn the back focus mechanism.
Fixed Lenses
Set the lens focus to infinity and view an image greater than two meters away. Focus the image
using the back focus screw. Set the lens focus as required.
Manual Iris Lenses
Open the iris fully and set the lens focus to infinity. View an image greater than 7 feet (2 meters)
away. Focus the image using the back focus screw. Set the lens focus and iris as required.
