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 T10YXXXXXX is used exceeds the applicable RF compliance
level above, the T10YXXXXXX should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the T10YXXXXXX.
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
T10YXXXXXX
The T10YXXXXXX is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
T10YXXXXXX can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment
(transmitters) and the T10YXXXXXX as recommended below, according to the
maximum output power of the communications equipment.
