WIRING -
■ Cable requirements
* Use a parallel conductor cable. Coaxial cable should
not be used.
* When existing chime wires are used, it is possible that the
wires may contain high voltage current. Locate and remove
the bell transformer before actually connecting
MJ-DS.
Parallel cable
YES
Coaxial cable
< $)•
NO
* Extra pair(s) in the installed cable can affect image quality,
and must be terminated with a 120 ohm resistor at each
end on both MJ-DS and MJ-1 AD.

■ Installation location
MJ-DS
MJ-DS employs CCD
camera and the
performance can be
affected by bright
direct light, such as
strong sunlight, gate
light, or street or porch
light which comes
directly into the
camera lens.

TECHNICAL PRECAUTIONS-
Installation location:
The MJ-DS is weather resistant, but for best results
it should be protected from direct weather
conditions. An eave or overhead cover is
recommended to protect it from direct rainfall.
Temperature:
The MJ-DS is rated to operate at temperatures
between -10° and 60°C (14° and 140°F). When the
outside temperature lowers rapidly, the camera lens
may fog up slightly, causing a blurry picture at the
inside monitor. The ventilation openings will allow
the moisture to evaporate, and the picture will return
to normal.
• Poor lighting conditions:
The MJ-DS’s infrared illumination will light the image
of the caller when positioned within 50cm, 20” in
front of the camera, and will see in near darkness (1
Lux of light).
• Cleaning:
Clean the unit with a soft cloth and neutral
household cleanser. Do not use an abrasive cleaner
or cloth.
