IRIS SENSITIVITY ADJUSTMENT
Rotate the iris sensitivity adjusting trimmer clockwise for higher sensitivity and counterclockwise for lower
sensitivity.
When obtaining higher sensitivity, be careful not to cause hunting.
IRIS ADJUSTMENT
Since the iris is precisely adjusted at the factory before shipment, normally the readjustment is not required.
But when an abnormality occurs for some reason, the readjustment can be made as described below.
The adjusting trimmer becomes visible inside the drive unit by removing the cap at the front of the drive unit.
Use a small screwdriver or similar implement to rotate the trimmer.
