HOW TO ADJUST THE PICTURE

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
adifferentdipswitch setting.Thetrim pod nextto theVGAconnector onthe VGAExtender
LR-R allows brightness adjustments for video.
The dip switches are located underneath the Receiver Unit. Peel off the silver sticker to
reveal the dip switch bay.
