14. Check if the cable length compensation (6) selector is set to the correct length. The length set must be the  
same as the length of the system cable (0-300m/900ft max.) connecting monitor and camera.  
Remark: If the length of the system cable is more than 200m/600ft, a mains power adapter (optional should  
be used (the max. cable length is 300m/900ft). Connect the adaptor to the mains and to the external supply  
socket (7) at the back of the camera.

Remark: If still no sharp object image is obtained, you should adjust the  
back-focus of the camera.  
Back-focus adjustment  
Caution: Back-focus adjustment is only necessary when no sharp object  
image is obtained with the focus adjustment ring.  
• Set focus adjustment ring to Far or Infinity (1).  
CL 66610005_304B.AI  
• Aim the camera at an object at least 15 metres/45 feet away.  
Remark: When bright light sources are positioned within thecamera view field; dim the light source.  
• Loosen the back-focus locking ring (2).  
• Rotate the lens, including the CS-mount ring, until the video image on the monitor is sharp.

The CS-mount of the camera allows you to use other lenses. The field of view (= covered area) of  
an 8mm lens is half of the field of view of the 4mm lens (see figure below).

The auto-iris lenses are recommended when the  
camera is used in environments with variable light  
conditions (eg. outdoors). By means of the auto-iris the  
amount of light going through the lens is regulated.

plugs. Never connect a telephone to the camera or system monitor.  
Tips for maintenance  
Cleaning  
You can clean the outside of the camera with a moist fluff-free cloth or shammy leather cloth.  
When cleaning the camera lens a special cleaning cloth should be used. Do NOT use cleaning fluids based  
on alcohol, methylated spirit, ammonia, etc..
