NOTE 1 At 80 MHz and 800 MHz, the higher frequency range applies.
NOTE 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
models JPD-100B is used exceeds the applicable RF compliance level
above, the models JPD-100B should be observed to verify normal
operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the models
JPD-100B.
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 models JPD-100B.
The models JPD-100B is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The
customer or the user of the models JPD-100B can help prevent
electromagnetic interference by maintaining a minimum distance
between
portable
and
mobile
RF
communications
equipment
(transmitters) and the models JPD-100B as recommended below,
according to the maximum output power of the communications
equipment.
