A WARNING
1. Do not connect any power source other than specified to terminals +, - on KC-1MRD.
Fire or damage to the unit could result.
2. Do not open KC-1 MRD. High voltage is present inside, and it can cause electric shock.^p
3. Do not change or alter KC-1 MRD. It can cause fire or electric shock. ^
4. Make sure wires are connected properly before plugging in power supply.
5. Keep the KC-1 MRD unit away from water or any other liquid. Fire or electric
shock could result.
6. Do not put any forcible strength on the video monitor. Damage may result.
7. Keep AC plug away from moisture or dust.
8. Keep AC cord away from being marred or crushed.
9. Do not plug or unplug with wet hands. o,
10. Do not put any metal into KC-1 MRD through openings. It can cause fire, ^
electric shock or unit damage.
CAUTION
1. Do not install or make any wire terminations while power supply is plugged in.
It can cause electrical shock or damage to the unit.
2. Verify chime volume while handset is on the hook. Chime sound from
KC-1 MRD speaker is loud, and may cause hearing damage.
3. In case of electrical storms, unplug power supply from AC outlet. It can cause
fire, electric shock, or power surge damage.
4. Mount KC-1 MRD on wall in a convenient location, but not where it could be
bumped or jarred.
5. Do not install KC-1 MRD in any of the following locations, as it may cause the
system to malfunction;
- High or extreme cold temperature area, such as under direct sunlight, near equipment
that varies in temperature, in front of air conditioner, inside a refrigerated area, etc.
- Places subject to moisture or humidity extremes, (bathroom, cellar, greenhouse, etc.)
- Places subject to environmental conditions, such as oil, dust, chemicals, salt, etc.
- Places subject to constant vibration or impact.
- Places where noise generating devices such as TV or radio are close by.
A^iENERAL PRECAUTIONS
1. KC-1 MRD equipment, except for KC-DAR, is designed for indoor use only.
Do not install outdoors.
2. KC-1 MRD system is not operational during a power failure.
3. In areas where broadcasting station antennas are close by, intercom system
may be affected by radio frequency interference.
4. Keep all DC wiring at least T(30cm) away from AC 100-240V wiring, fluorescent
lighting, or dimmer switches. Otherwise, cross AC wiring at a 90° angle.
5. KC-1MRD system has to be kept in the distance of more than 3'3" (1m) away from
TV or radio.

Mounting Precautions
• The video door station employs a CCD camera, and
its performance may be affected by bright direct light,
such as strong sunlight, gate light, street or porch light
which shines directly into the camera lens.
• Install the video door station in front of where the
caller will normally stand.
• When outside temperature lowers sharply, after rain,
etc., the inside of the camera may fog up slightly,
causing a blurry picture. This is not a malfunction.
Normal operation will be restored when moisture
evaporates.
2 WIRING
Wiring Precautions^^-
• Keep all wiring at least 30cm, 20" away from AC 100~240V wiring,
fluorescent lighting, or dimmer switches.
It may cause noise interference or malfunction.
• Use a parallel conductor cable. Coaxial cable cannot be used.
Parallel cable Coaxial cable
YES diiar NO
Vinyl jacketed, PE (polyethylene) insulation cable is
recommended.
For other types of cables, normal operation and max.
communication distance cannot be guaranteed.
• Extra wire(s) in the installed cable can affect image quality, and
must be terminated with a 120 ohm resistor at each end.
Extra wires
120 ohm
KC-DAR KC-1MRD
If proper cable is not used, system may malfunction.
