Before cleaning, the device must be disconnected from power supply!
Safety Warnings
– Do not place the videophone in the proximity of TV receivers or into environments with high temperature or humidity.
– Do not touch the TFT LCD display or the monitor by hand and do not disassemble the door unit.
– If sunlight shines directly into the lens of the door camera unit, the image on the videomonitor may become illegible.
– Do not subject the device to vibrations or falls.
FAQ
The device does not work
Check the cables and the connection of the power adapter to the network. If you extended the cable from the power adapter,
check that the polarity is correct. Measure the adapter with a multimeter. The output voltage on the connector should be
14.5 V DC (+/- 1 V).
The image/sound is not clear, the device does not ring
Remove the monitor or the door panel and connect it using a short cable to eliminate the possibility of a disrupted conductor
in the house.
Then check the image and sound settings (brightness, contrast, colour, volume).
The lens steams up
This occurs mainly during cold weather, where condensation occurs due to the temperature difference between the wall and
the door unit itself. If water condenses on the lens, we recommend thoroughly drying the unit and modifying the installation.
Spontaneous ringing
Spontaneous ringing is caused by moisture entering the camera. Water short-circuits the contacts on the lock switch and the
device will start ringing on its own. We recommend dismounting the door unit, drying it thoroughly and spraying it with water
repellent for electronics.
High-pitched noise (feedback)
The source of feedback is the scattering of output sound from the door camera unit. The sound feeds back into the microphone
where it further amplifies.
You can solve this by decreasing the microphone sensitivity and speaker volume.
In door units with adjustable elements, you can do this by turning the potentiometers.
In units without these control elements, you can reduce the microphone volume mechanically by a piece of soft foam.
The device does not open the lock
Check that the cabling is intact.
Measure the voltage on the lock terminals using a multimeter. The lock requires a voltage of 12 V to trigger. If the value is lower,
use stronger conductors for the lock control.
Sudden decrease in microphone sensitivity
Check the cleanliness of the microphone opening, or clean it gently with a thin, blunt object.
Be careful not to damage the microphone!
Do not dispose of electrical appliances as unsorted municipal waste; use sorted waste collection points. Contact local
authorities for up-to-date information about collection points. If electrical appliances are deposited in waste landfills,
hazardous substances may leak into the groundwater, enter the food chain and harm your health.
