Manufacturer's EMC guidelines
NOTE 1: The higher frequency range applies for 80 MHz and 800 MHz.
NOTE 2: These guidelines may not apply in all cases. The diffusion of electromagnetic parameters is affected by
absorption and reflections from buildings, objects and people.
The field strength of stationary transmitters, such as base stations for cordless telephones and land mobile radios,
amateur radio stations, AM and FM radio and television transmitters cannot be specified precisely in advance, in
theory.
In order to determine the electromagnetic environment relating to stationary transmitters, you should consider a
study of the location. If the measured field strength at the location where the Tel-O-Graph
®
Tel-O-Graph GSM plus is used exceeds the upper compliance level, the Tel-O-Graph
plus should be kept under observation to ensure proper functioning. If unusual performance characteristics are
observed, additional action may be necessary, such as changing the orientation or location of the
