PRECAUTIONS
General Prohibitions Prohibition on Subjecting the Unit to Water
Prohibition to Dismantle the Unit
WARNING
(Negligence could result in death or serious injury.)
1. High voltage is present internally. Do not open the case. Electric shock could result.
2. Do not dismantle or alter the unit. Fire or electric shock could result.
EnglishFrançaisNederlands
3. Do not connect any non-specified power source to the +, - terminals, and do not
install two power supplies in parallel to a single input. Fire or damage to the unit
could result.
4. Keep the unit away from water or any other liquid. Fire or electric shock could result.
5. Do not put any metal or flammable material into the unit through the openings. Fire
or electric shock could result.
6. Do not use power supply with a voltage other than specified. Fire or electric shock
could result.
7. Do not connect any terminal on the unit to AC power lines. Fire or electric shock
could result.
CAUTION
(Negligence could result in injury to people or damage to property.)
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. Before turning on power, make sure wires are not crossed or shorted. If not, fire or
electric shock could result.
3. When mounting the unit on wall, install the unit in a convenient location, but not
where it could be jarred or bumped. Injury could result.
4. For power supply, use Aiphone power supply model specified with system. If nonspecified product is used, fire or malfunction could result.
5. Do not install the unit in any of the following locations. Fire, electric shock, or unit
trouble could result.
∗ Places under direct sunlight, or near heating equipment that varies in temperature.
∗ Places subject to dust, oil, chemicals, etc.
∗ Places subject to moisture and humidity extremes, such as bathroom, cellar,
greenhouse, etc.
∗ Places where the temperature is quite low, such as inside a refrigerated area or in
front of air-conditioner.
∗ Places subject to steam or smoke (near heating or cooking surfaces).
∗ Where noise generating devices such as dimmer switches or inverter electrical
appliances are close by.
6. Do not put anything on or cover the unit with cloth, etc. Fire or unit trouble could
result.
7. Do not press on the LCD or subject it to a high impact. The LCD glass could be
punctured and result in an injury.
8. If LCD is punctured, do not allow contact with the liquid crystal inside.
Inflammation could result.
∗ If necessary, gargle your mouth and clean your eyes or skin with clear water for at
least 15 minutes, and consult your doctor.
General Precautions
GENERAL PRECAUTIONS
1. Keep the unit more than 1 m away from radio or TV set.
2. This unit is for indoor use only. Do not use outdoors.
3. In areas where broadcasting station antennas are close by, the intercom system may
be affected by radio frequency interference.
4. As to other manufacturer's devices (such as sensor, detectors, door releases) used
with this system, comply with the Specifications and Warranty conditions that the
manufacturers or venders present.
5. Keep the intercom wires more than 30 cm (12") away from AC 100~240 V lines.
Noise and malfunction could result.
6. If the unit is down or does not operate properly, unplug the power supply or turn off
the JF-2MED and JF-2HD Power switches.
7. The unit is for wall-mount use only. For desktop applications, use desk stand.
8. When wall-mounted, the unit may become dusty. Clean with a soft cloth.
9. The unit case may become a warm with use, but this is not a unit malfunction.
10. If a cellular phone is used close by, the unit may malfunction.
11. If must be noted in advance that the LCD panel, though manufactured with very high
precision techniques, inevitably will have a very small portion of the picture
elements steadily lit or not lit at all, which is not considered a unit malfunction.
12. Refrain from using the color monitor station in sunlit areas.
13. At night, due to reduced lighting on the object, the monitor sees more noise and the
face becomes more difficult to see, but this is not malfunction.
14. Talk within 50 cm (20") or less from the unit. If you stand too far away, it may be
difficult for the other person to hear the communication.
15. If there are loud noises around the unit (such as music playing or children crying),
the sound may break up and be difficult to hear.
16. During communication, if you speak before the other person has finished talking,
your voice may not be heard. Communication will proceed smoothly if you wait
until the other person has finished before speaking.
17. At a gate or porch illuminated by fluorescent lamp, the picture may vary, but this is
not a malfunction.
18. When outside temperature lowers sharply after rainfall, etc., the inside of the camera
may fog up slightly, causing a blurry picture, but this is not a malfunction. Normal
operation will be restored when moisture evaporates.
19. Due to the environmental sound around the unit, it may hinder smooth
communication, but this is not a malfunction.
