■ Make sure your cables are securely connected at both ends.
■ If you’re using an extension cable, you may pick up interference if the cable is not
adequately shielded. You may need to use a signal amplifier for longer cables.

off your laptop’s LCD display (see page 80).
The picture is blurry.

■ There may be dirt on the lens. Clean the lens as described on page 68.
■ Adjust the focus (see page 29).
