Control Maintenance - continued
Slide the shaft back into the control gland and gently slide it back and
forth a few times without fully removing the shaft from the gland.
Replace the knob, noting the flat area on the shaft. The set screw in the
knob should tighten down against the flat area on the control so the
knob does not turn on the shaft.
After completing this procedure, close the housing and submerge it in
water without the camera inside. Check the control for watertightness.
