94 Flowmaster User’s and Service Manual | LBL-000990 [B] Appendix D
with the following symbol:
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 Flowmaster is used
exceeds the applicable RF compliance level above, the Flowmaster should be
observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the
Flowmaster.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be
less than 6 V/m.
Recommended separation distances between portable and mobile RF
communications equipment and the Flowmaster
The Flowmaster is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the
Flowmaster can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the Flowmaster as recommended below, in
accordance to the maximum output power of the communications equipment.
WARNING: Portable RF communications equipment (including
peripherals such as antenna cables and external antennas) should be used no
closer than 30 cm (12 inches) to any part of the Flowmaster system, including
cables specified by the manufacturer. Otherwise, degradation of the
performance of this equipment could result.
