Frequencies

When operating wireless systems, there are several key issues which have to be taken into consideration:

It is necessary to select the frequencies very carefully. Interference can be caused by what is called “inter- modulation” – in simple terms this means the effect created when two frequencies interact. 
You must ensure that in any multi-channel system, no two frequencies are the same and care should be exercised because it is possible for some frequencies to interfere with each other.

Please consult your dB Technologies dealer for assistance.
