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.
