If you do not see the Welcome screen, you may need to change channels or change the 
video source your TV uses:

• If you used coaxial RF cable 

to connect your DVR to the TV, make sure 

you’re viewing the same channel (3 or 4) that you selected using the switch on the 
back of your DVR. 

• If you used Composite Video and L/R Audio cables

  to connect your DVR, 

make sure your TV is displaying the appropriate video source. You may need to use 
the “INPUT,” “SOURCE,” or “TV/VIDEO” button on your TV or TV’s remote 
control to change video sources. If you are having trouble changing the video source, 
refer to the instructions that came with your TV.

• If you did not connect the DVR directly to the TV but are instead passing the signal 

through your VCR, make sure your VCR is displaying the appropriate video source. 
You may need to use the “Input,” or “Source” button on your VCR or VCR’s remote 
control. Also, some VCRs only pass the signal through when they are turned either on 
or off. If you are having trouble displaying the correct video source, refer to the 
instructions that came with your VCR.

• If you are still having trouble, double-check your connections.
