The lens is dewing
This phenomenon occurs especially in the cold season, when condensation occurs
due to the temperature difference between the wall and the door station itself. In
case of condensation, we recommend to dry the station thoroughly and adjust the
installation.
S
pontaneous ringing
Spontaneous ringing causes moisture to enter the camera. The water short-circuits
the contacts of the lock switch and the device rings spontaneously. We recommend
disassembling the door station, drying it thoroughly and spraying it with a water-
repellent electronics varnish.
Whi
stling (feedback)
The source of the feedback is the splintering of the outgoing sound of the door
station. The sound is fragmented and returned to the microphone where it is
further amplified. This can be eliminated by lowering the speaker volume.
I
t doesn't open the lock
Check the integrity of the wiring. Use a multimeter to measure the voltage at the
terminals of the lock. The lock requires 12 V to trigger. If this value is lower, we
recommend using stronger wires to operate the lock.
Sudden drop in microphone sensitivity
Check the microphone hole for cleanliness, or use a thin blunt object to lightly clean
it. Damage to the microphone may occur if careless!
