Important Information6For best performanceBefore usingL�It is prohibited to disassemble or modify this unit. Contact the dealer where you purchased this unit for repair.L�When power fails, this unit cannot be used.L�For the recorded image:The recorded image may be lost when:– Mishandled– Electric shock or radio wave interference occurs.– The power is turned off during use.(We might not be held responsible for the damage.)Location/avoiding noiseL�The main monitor station, the sub monitor station and the camera use radio waves to communicate with each other. Formaximum distance and noise-free operation, we recommend the following:– Placing the unit away from electrical appliances such as:• TVs.• personal computers.• Microwave ovens.• Wireless LAN appliances.• Other sub monitor stations.• Other cameras (optional).• If you use the sub monitor station near a microwave oven which is being used, noise may be heard. Move away from themicrowave oven and closer to the main monitor station.For places to install the main monitor station and the door station, see the Installation Guide included separately.EnvironmentL�Keep the unit away from electrical noise generating devices, such as fluorescent lamps and mortors.L�The unit should be kept away from excessive smoke, dust, high temperature and vibration.L�The unit should not be exposed to direct sunlight.L�Do not place heavy objects on top of the unit.L�When you leave the unit unused for a long period of time, unplug it from the power outlet.L�The unit should be kept away from heat sources such as heaters, kitchen stoves, etc. It should not be placed in roomswhere the temperature is less than 0 °C or greater than 40 °C. Damp basements should also be avoided.L�The maximum calling distance (approx. 100 m) may be shortened when the unit is used in the places:– Where there are following obstacles between the main monitor station and the sub monitor station:• Metal doors or metal shutters.• Heat insulation including aluminium foil.• Concrete walls or walls made of galvanized iron sheet.• When using the sub monitor station on the different floor or house in the same grounds from where the main monitorstation has been installed.• Many walls.L�Operating near 2.4 GHz electrical appliances may cause interference. Move away from the electrical appliances.Important:L�When you move the sub monitor station from a cold place to a warm place, wait a little while to let the sub monitor stationadapt to the change in environment before use. In this case, condensation such as the formation of dew may occur,resulting in error or malfunction.TappingThis unit uses digital wireless technology so that a call is rarely intercepted. However, calls may be tapped by a third partybecause the unit also communicates using radio waves.L�“Tapping” means that the other party intercepts a radio message intentionally or accidentally by using a receiver.Using near medical equipmentL�Consult the manufacturer of any personal medical devices, such as pacemakers or hearing aids, to determine if they areadequately shielded from external RF (radio frequency) energy. (The unit operates in the frequency range of 2.4 GHz to2.48 GHz, and the power output level can range from 0.03 to 0.175 watts.) Do not use the unit in health care facilities if anyregulations posted in the area instruct you not to do so. Hospitals or health care facilities may be using equipment that couldbe sensitive to external RF (radio frequency) energy.
