Controlled RF interference variables
The lighting system is intended for use in an electromagnetic environment where the RF disturbances are monitored. To prevent
electromagnetic interference, maintain a minimum distance between the portable and mobile HF communications devices
(transmitters) and the above-mentioned device according to the maximum output power of the communications equipment, as
recommended below.
For transmitters, whose maximum rated output is not indicated in the table above, the recommended safety distance D in
metres (m) can be determined using the equation, which belongs to the respective column, whereby P is the maximum rated
output of the transmitter in watts (W) according to the information of the transmitter manufacturer.
Notes:
At 80 MHz and 800 Hz, the higher frequency range applies. These guidelines may not be applicable in all cases. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and people.
Distance for portable RF communication device and their peripherals
Do not use portable RF communication device (including peripherals such as antenna cables and external antenna)
at a distance below 30 cm (12 inch) to the lighting system including its cables specified by the manufacturer. This
can otherwise lead to a decline in the functionality of the system.
