■About the Camera Cleaning Function
Prolonged use can lead to noise on the monitor and
divergence of preset positions.
If such conditions persist even after you perform cam-
era cleaning (page 41), use the special setup menu to
execute the "REFRESH" operation (page 50).
If you are using a matrix switcher with a camera clean-
ing function (WJ-SX550C), configure the matrix switch-
er Auto Cleaning settings so cleaning is performed
once a day.
■Downloading (saving) or uploading (recovering)
camera preset data
When downloading or uploading camera preset data,
aim the camera at static objects such as a wall without
moving the camera as much as possible.
