7. Wireless transmission
The wireless range depends on a variety of environmental factors. The local conditions at the installation
site may have a negative impact on the range. When there are no obstructions between the receiver and
transmitter, a range of up to 150m is possible, but this range will be considerably less within buildings.
The following environmental conditions compromise both the range as well as the frame rate:
Mobile communication masts, high-tension pylons, electrical wires, ceilings and walls, devices with the
same or an adjacent wireless frequency.
Warnings
Observe all safety and operating instructions before putting the device into operation for the first time.
1. Observe the following information to avoid damage to the mains cable and plug:
Do not modify or manipulate the power cable or plug.
Do not pull the cable when disconnecting the device from the mains power – always hold of the plug.
Ensure that the mains cable is positioned as far away as possible from any heating equipment, as this
could otherwise melt the plastic coating.
The power supply unit for the door station must be protected from damp and moisture.
2. Follow these instructions. Non-compliance with these instructions could lead to an electric shock.
1. Never open the housing or power supply unit.
2. Do not insert any metallic or flammable objects into the device.
3. Use overvoltage protection to prevent damage caused by overvoltage (e.g. electrical storms).
3. Disconnect defective devices from the power immediately and contact your specialist dealer.
If in doubt, have a specialist technician carry out assembly, installation, and connection of the
device. Improper or unprofessional work on the power supply or domestic installation puts both
you and other persons at risk.
Connect the installations so that the power supply circuit and low-voltage circuit always run
separately from each other. They should not be connected at any point or be able to become
connected as a result of a malfunction.
Avoid the following adverse conditions during operation:
Moisture or excess humidity
Extreme heat or cold
Direct sunlight
Dust or flammable gases, vapors, or solvents
Strong vibrations
Strong magnetic fields (e.g. next to machines or loudspeakers)
The camera for the door station must not be directed toward the sun, as otherwise the sensor may be
destroyed.
The camera must not be installed on unstable surfaces
Unpacking the device
Handle the device with extreme care when unpacking it.
If the original packaging has been damaged, inspect the device. If the device shows signs of
damage, return it in the original packaging and inform the delivery service.
