Caution
1. At 80 MHz and 900 MHz, the higher frequency range applies.
2 These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from structures, objects and people.
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 ACCUNIQ BP250 is used exceeds the applicable RF
compliance level above, the ACCUNIQ BP250 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the ACCUNIQ BP250.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3
V/m.
4) Recommended separation distances between portable and mobile RF communications
equipment and the ACCUNIQ BP250
The ACCUNIQ BP250 is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the ACCUNIQ BP250 can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF
communications equipment (transmitters) and the ACCUNIQ BP250 as recommended below, according to
the maximum output power of the communications equipment.
