Beurer BC 30 Gebrauchsanweisung Seite 94

a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM
and FM radio broadcast and TV broadcast cannot be predicted theoretically with accuracy. To assess the electromagnetic environment due to
fixed RF transmitters, an electromagnetic site survey should be considered. If the measured field strength in the location in which the BC30 is
used exceeds the applicable RF compliance level above, the BC30 should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as re-orienting or relocating the BC30.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

For ME EQUIPMENT and ME SYSTEMS that are not LIFE-SUPPORTING
Recommended separation distances between portable and mobile RF communications equipment and the BC30
The BC30 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the
BC30 can help prevent electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equip-
ment (transmitters) and the BC30 as recommended below, according to the maximum output power of the communications equipment.
