Guidelines and Manufacturer Statement – Electromagnetic Immunity to Interferences
The Loop-/Event Recorder Beam
®
is intended for operation in the following referred to envi-
ronment. The customer or the user of the Loop-/Event Recorder Beam
®
should ensure that
it is used in such an environment.

Portable and mobile radios should
not be used closer to the Loop/ Event
Recorder Beam® including cables
than the recommended safety distan-
ce, which is calculated by using the
respective equations for the transmit-
ting frequencies.
Recommended Safety Distance:
d= 1,17 * Root(P/W) for 80 MHz to
800 MHz
d= 2,33 * Root(P/W) for 800 MHz to
2,5 Ghz
where P equals the maximum nomi-
nal power of the transmitter in Watts
according to the transmitter manufac-
turer and d is the recommended safe-
ty distance in Meters (m). The field
strength of a stationary radio transmit-
ter should, according to a local evalu-
ation, be less than the corresponding
level for all frequencies. In the vicinity
of devices, which carry the symbol for
“non-Ionising emission”, interference is
possible.
NOTE 1: At 80 Mhz and 800 Mhz the higher frequency range applies.
NOTE 2: These guidelines may not apply to all cases.
The emission of electromagnetic values is influenced by absorption and reflection of
buildings, objects and people.
The field strength of stationary transmitters such as the base stations of mobile phones
or mobile rural broadcasting devices, amateur radio stations, AM/FM Radio and TV sta-
tions cannot be precisely predetermined theoretically.
In order to calculate the electromagnetic environment with regard to stationary transmit-
ters, a local evaluation should be considered.
If the measured field strength at a location, where the Loop-/Event Recorder Beam
®
is
used, is exceeding the above mentioned corresponding level, the Loop-/Event Recorder
Beam® should be observed in order to prove the intended functionality. If extraordinary
performance characteristics are observed, additional actions may be necessary, such as
changed positioning or another location of the Loop/Event Recorder Beam
®
.
