• It must be noted in advance that the TFT color
LCD panel, though manufactured with very
high precision techniques, inevitably has a
very small portion of picture elements that are
steadily lit or not lit at all, which is not considered
a unit malfunction. The LCD monitor looks dark
in the bright sunlit area, etc. Adjust BRIGHT
control to high position to increase monitor luminosity,
or reduce ambient lighting.
• When holding handset close to video monitor, the
image may vary, but this is not a malfunction.
• KB-3MRD unit surface becomes warmer while
being powered, but this is not a malfuction.
• Strong light, such as direct sunlight, etc. may cause
silhouette on the monitor, but this is not a malfunction.
• When outside temperature lowers sharply after
rainfall, etc., the inside of camera may fog up slightly,
causing a blurry picture, but this is not a malfunction.
Normal operation will be restored when moisture
evaporates.
• KB-3MRD may collect dust on the top of the unit.
Clean unit as needed.
• Do not apply any caulking sealant around video
door station. The openings at the bottom will help
rain to dissipate.

dampened with neutral household cleanser. Never
use any harsh cleaner or cloth. Do not spray high-
pressure water on KB-DAR.
