HOW TO ADJUST THE PICTURE
4
The first step in adjusting the video quality is to display text and a graphic on your monitor
(i.e. desktop icons). Then set your computer to the resolution that you will be using most
frequently. The dip switches are used to set the focus and sharpness of the picture to the
best possible setting. Set the dip switches to the settings that are recommended for the
different lengths of CAT5 cable (see chart below). Verify that the picture quality is to your
satisfaction. If the recommended setting does not produce a great quality picture, try using
a different dip switch setting.
The dip switches are located underneath the Receiver Unit. Peel off the silver sticker to
reveal the dip switch bay.
0-25 Feet All dip switches OFF for all colors.
26-55 Feet Set dip switch #1 ON all colors. 2,3,4 remain OFF.
56-85 Feet Set dip switch #2 ON all colors. 1,3,4 remain OFF.
116-145 Feet Set dip switch #3 ON all colors. 1,2,4 remain OFF.
146 Feet and Up Set dip switch #4 ON all colors. 1,2,3 remain OFF.
NOTE: The dip switches are set to the OFF position when the switch is closest to the
number or in the down position.
