around the equipment marked
with the following symbol:
NOTE 1: At 80 MHz and 800 MHz the highest frequency band is applied.
NOTE 2: These guidelines may not be applicable to all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects and
people.
a
Field strengths set by fixed transmitters, such as radio base stations, telephones
(cellular/cordless) and land mobile radios, amateur radio, AM and FM radio broadcast
and TV broadcast cannot be theoretically predicted with accuracy. To assess an
electromagnetic environment due to fixed RF transmitters, it is recommended an
electromagnetic inspection on the place. If the measure of the field strength at the
location where the equipment is used exceeds the conformity level used above, the
unit must be observed in order to check whether the operation is normal. If an
abnormal performance is observed, additional procedures such as reorientation or
replacement of the equipment may be necessary.
b
Over the frequency range from 150 KHz to 80 MHz, the field strength must be less
than 10 V/m.
Recommended separation distances between the communication equipment of RF
portable and mobile and SONOPEEL
SONOPEEL is destined to be used in electromagnetic environment in which RF
disturbances are controlled. The user of the equipment can help to prevent the
electromagnetic interference by maintaining the minimum distance between the
communication equipments of RF portable and mobile (transmitters) and SONOPEEL, as
recommended below, according to the maximum power of the communication
equipments.
