Portable and mobile radio transmitter should
not be use within the recommended safety
distance to the SWIFTCAM (including the
lines)!
The recommended safety distance will be
calculate by the appropriate transmitting
frequency formula.

In the enviroment of equipment which bore the
following pictograph, it is possible to appear
interferences.
Note 1: At 80 MHz and at 800 MHz the higher result is valid.
Note 2: This guideline may not be the case for all situations. The spread of electromagnetic waves will
be affect by absorption and reflexion of buildings, objects and humans.

The electric field strength of fixed transmitter, like wireless telephones, mobile radio services, AM- and FM
broadcast transmitter and TV transmitter, couldn’t be predetermine correctly. In order to ascertain the
electromagnetic enviroment at fixed HF-transmitter, it is commendable to inspect the location. If the ascertained field
strength at the SWIFTCAM location exceed the specified correspondence level, it’s may be necessary to adopt other
means, e.g. reorientation or removal the SWIFTCAM.
By means of the frequency range from 150 kHz to 80 MHz the field strength is less than
3 V/m
