Confi rmation and Preparation
• It must be noted in advance that the LCD panel, though manufactured with
very high precision techniques, inevitably will have a very small portion of its
picture elements always lit or not lit it at all. This is not a malfunction.
• Hands-free calling prioritizes the loud side and switches between
transmission and reception automatically. The quiet side can be heard.
If there are loud noises around the unit, the sound may break up and be
diffi cult to hear.
• During communication, if you speak before the other person has fi nished
talking, your voice may not come through clearly. Allow each person to fi nish
speaking before responding.
• Warm-color lighting shining on the video door station may change the tint of
the image on the screen.
• If light, such as illumination, enters the camera, the liquid crystal display may
fl icker brightly or objects may appear dark due to backlight interference. This
is not a malfunction.
• If the subject has a line pattern or thin pattern, background or color may
differ from the actual images. This is not a malfunction.
• If the video door station is subject to direct sunlight or other strong light,
white lines may appear on the liquid crystal display and refl ected patterns
may appear due to the light. It makes diffi cult to see the face of the visitor.
This is not a malfunction.
• If glare from an LED light or fl uorescent light, etc. enters the camera, black
stripes may appear on the liquid crystal display of the master station, the
screen may fl icker, and colors may differ. This is not a malfunction
• The discrimination between day and night is performed automatically by the
video door station. Though the discrimination result may vary depending on
the installation environment, it is not a malfunction.
• At night, due to reduced lighting on the object, the screen sees more noise
and faces become more diffi cult to see. This is not a malfunction.
• When outside temperature lowers sharply after rainfall, etc., the inside of
the camera may fog up slightly, causing a blurry images, but this is not a
malfunction.
Normal operation will be restored when moisture evaporates.
