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 device is
used exceeds the applicable RF compliance level above, the device should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the device.
Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM –
for EQUIPMENT or SYSTEM that are not LIFE-SUPPORTING
Recommended separation distances between
portable and mobile RF communications equipment and the device
The device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The customer or the user of the device
can help prevent
electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the device as recommended below,
