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 SBC 41 is used exceeds the applicable RF compliance level above, the SBC 41 should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting or relocating the SBC 41.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Recommended separation distances between portable and mobile RF communications equipment and the SBC 41
The SBC 41 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the SBC 41 can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the SBC 41 as recommended below, according to the maximum output
power of the communications equipment.
