Precautions for installation
To avoid malfunction or communication disturbances, do not install the doorphone or the main monitor in
the following locations:
– Places where vibration or any other kind of impact occurs.
– Places where echoing is frequent.
– Places near a high concentration of dust, hydrogen sulphide, ammonia, sulphur, or noxious fumes.
For the doorphone
R If a strong light is shining on the doorphone, the visitor’s face may not be distinguishable. Do not place
the doorphone in the following locations:
– Where most of the background is the sky.
– Where the background is a white wall, and direct sunlight will reflect off it.
– Where direct sunlight will shine on the doorphone.
R Do not place the doorphone in locations where echoing occurs, as this will cause the doorphone to
beep frequently.
R Make sure the rear of the doorphone is not subject to water.
R Depending on the installation location, condensation may form on the doorphone’s lens cover. This
may cause images to become obscured. Condensation will dissipate as the temperature rises.
For the main monitor
R Install the main monitor away from electronic appliances such as TVs, radios, personal computers, air
conditioners, boiler control panels with intercom, home security equipment, wireless devices, or digital
cordless phones.
R Do not install the main monitor in places where it will be affected by extremely high-frequency radio
waves (near broadcasting antennas etc.). This may cause the display to flicker or an interrupting noise
to occur.
R Leave at least 20 cm of space above, below, and to the left and right sides of the main monitor. Do not
install on a wall that is deeply recessed.
R Do not install the main monitor inside a wall.
R Be sure to install the main monitor more than 5 m away from the doorphone.
R The product operates in the frequency range of 2.412 GHz and 2.472 GHz with a peak transmission
power of 100 mW (max.). Refer to the "For best performance" section in the Operating Instructions.
R In areas surrounded by a high electrical field, disturbances may occur in the main monitor’s image or
sound.
