Adjustments
An adjustment may be necessary to center the picture on the
monitor. The VHDC300 has an access hole marked "H. ADJ". To
adjust centering, insert a screwdriver into the access hole. Turn
clockwise or counterclockwise as required. If turned too far in
one direction the picture may disappear. If this happens, turn the
adjustment back until the picture reappears.
