• 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.
CLEANING
Clean KB-3MRD and KB-DAR with a soft cloth
dampened with neutral household cleanser. Never
use any harsh cleaner or cloth. Do not spray high-
pressure water on KB-DAR.
