Buried cables are more aesthetic as they do not clutter the landscape with utility poles and wires but may be less easy to access to make changes or repairs. See Call Before Digging. burn-in A diagnostic preliminary operation sometimes at high temperatures to test devices and circuits in order to identify those likely to fail. In electronics many problems will show up early in the first few weeks of operation or under stress from heat and humidity. Sometimes called early failure period. burn-in monitor An undesirable ghost image on the coating inside a cathode-ray tube CRT monitor resulting from the persistent display of the same image or similar images. Monitor bum-in can be prevented by turning the monitor off when not in use and using screen savers that darken the screen completely or second-best that move around small low-contrast images.
