ers, back boxes, rain shelters, hood covers and
modules see section “intercoms” on page 11 to

Adjustments
If necessary, you can manually modify the cam-
era position by means of the horizontal and
vertical adjustments located on the back of the
camera.
To do this, you must:
- remove the upper screw of the push-button
panel to access the back of the camera;
- loosen the screw of the horizontal or vertical
adjustment (or both screws, if you want to
adjust the image in all the directions);
- move the camera in the desired direction;
- tighten the screw to block the camera in the
desired position;
- fix the push-button panel.

MD40, MD40C and MD40D cameras have the same specifications as models MD41, MD41C
and MD41D, except that they have not horizontal and vertical adjustment.
