The field strength of stationary wire-
less radio transmitters as measured
locally
a
should be lower than the
conformance level at all frequen-
cies.
b
Interference is possible in the vicin-
ity of devices that bear the following
symbol.
Note 1: At 80 MHz and 800 MHz, the higher frequency range applies.
Note 2: These guidelines may not be applicable in every case. The propagation of
electromagnetic waves is subject to absorption and reflection by buildings, objects,
and people.
a
The field strength of stationary transmitters such as base stations of mobile tele-
phones and land mobile radio devices, amateur radio stations, AM and FM radio and
television broadcasting stations cannot be determined based on theoretical considera-
tions. A site study should be considered to determine the electromagnetic environment
in terms of stationary transmitters. If the field strength measured at the location at
which the MASTERsurg LUX Wireless is used exceeds the conformity levels specified
above, the MASTERsurg LUX Wireless should be monitored to confirm that it is func-
tioning as intended. Should unusual performance features be observed, additional
measures may be required, such as, e.g., a different alignment or another location for
the MASTERsurg LUX Wireless.
b
In the frequency range of 150 kHz to 80 MHz, the field strength should be less than
3V
