Phase adjustment may be necessary in multiple camera installations to prevent 
picture roll when switching between two cameras. To adjust the vertical phase 
while switching between two cameras, turn the Line lock adjustment screw on 
one camera until there is no vertical roll. See 

 for color cameras. The 

Wide Dynamic Range cameras use line lock adjustment buttons to adjust the 
vertical phase (see 

If the phase cannot be adjusted to prevent picture roll, reverse the 

power polarity.

The backlight compensation (BLC) adjusts the electronic shutter speed of the 
camera based on the light levels in specific areas of the scene. This adjustment

To adjust the BLC, set the BLC switch to ON (see 

 for color cameras).
