Portable and mobile RF
communications equipment
(radio devices, incl. antennas or
cables) should be used no closer
to any part of the MOS-1302B
than the recommended safety
distance of 300 mm (or 12
inches).
The field strengths from fixed RF
transmitters, as determined by
field surveys of electromagnetic
fields, should be less than a
compliance level of 3 V/m in
each frequency range.
Interference may occur in the
vicinity of equipment marked

Info 1: These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from bildings, objects and people.
The field strengths from fixed transmitters, such as wireless (cellular / cordless) telephones and mobile
terrestrial radio base stations, amateur radio, AM / FM radio broadcasts and TV broadcasts cannot be
accurately and theoretically predicted. In order to confirm the electromagnetic environment caused by
the fixed RF transmitter, it is desirable to consider an electromagnetic field survey. If the measured field
strength exceeds the compliance level as specified above at the location where the MOS-1302B is used,
the MOS-1302B should be observed to verify correct functionality. If abnormal performance is observed,
additional measures may be necessary, such as re-orienting or relocating the MOS-1302B.
