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.

3. Do not connect any power source other than specified to terminals +,- nor install
two power supplies in parallel to 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 into the unit through the openings. Fire or electric shock
could result.

6. When existing chime wiring is used, it is possible that it contains AC power. Unit
damage or electric shock could result. Ask a qualified electrician.

7. Do not puncture the LCD panel with a sharp-edged tool. Damage to the LCD panel
could occur, causing a liquid crystal spill. If liquid crystal makes contact with the
eyes or mouth, immediately wash away with water.

8. Do not put high pressure on the monitor cover. If fractured, injury could result.

9. Do not use a power supply with a voltage other than specified. Fire or electric
shock could result.

CAUTION

(Negligence could result in injury to people or damage to property)

1. Before turning on the power, make sure wires are not crossed or shorted. Fire or
electric shock could result.

2. Mount the unit onto the wall in a place where it cannot be easily jarred or bumped
by people. Injury could result.

3. Do not make any wiring connections while the power supply is turned on. Electric
shock or unit trouble could result.

4. Do not install or use the unit in any of the following places.

. Places in direct sunlight, or near heating equipment that varies in temperature.

*

. Places subject to metal particles, dust, oil, chemicals.

*

. Places subject to moisture and humidity extremes, such as bathrooms, cellars,

*

greenhouses, etc.

. Places where the temperature is quite low, such as inside a refrigerated area or in

*

front of an air-conditioner.

1. This unit is for indoor use only. Do not use outdoors.

GENERAL PRECAUTIONS

2. When wall-mounted, the unit may become black and sooty. This does not indicate
unit trouble.

3. In areas where broadcasting station antennas are close by, the intercom system
may be affected by radio frequency interference.

4. The unit may become a little warm with use, but this is not a malfunction.

5. If a cellular phone is used close by, the unit may malfunction.

6. 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 at all. This is not considered a unit malfunction.

7. Keep the unit more than 1 m away from Radio or TV set.

8. If the monitor station is operated near office equipment, radios or TVs, it will be
affected by radio wave interference or noise. Carefully select the place of use.

9. Ambient noise around the unit may prevent normal communication. This is not
unit trouble.

10.As to other manufacturer's devices, such as sensor, used with this system, comply
with the relative specifications and warranty conditions of the devices.

11.If the system is down or does not operate properly, turn off the unit power switches.
