Recommended Safety Distance - Barkey plasmatherm Instructions For Use Manual

Gui delines and manufacturers declarati on - Electromagnetic i mmunity
The Barkey p lasmatherm is intended for operation in one of the electro magnetic enviro n-
ments listed below. The customer or user of the Barkey plas matherm must ensure that it is
operated in one of these environments.

NOTE 1 At 80 M Hz and 800 MHz the higher frequency range applies.
NOTE 2 These guidelines may not apply in all cases. The propagation of electromagnetic
variables is affected by absorption and reflection of buildings, objects and people.
a
The field strength of static transmitters, such as base stations of radio telephones and
mobile land radios, amateur radios, AM and FM radio and telev ision transmissions cannot be
accurately theoretically determined in advance. You should consider carrying out a site survey
to determine the electro magnetic environ ment with regard to static transmitters. If the meas-
ured field strength at the location where the Barkey plasmatherm is being used exceeds the
above compliance levels, the Barkey p lasmatherm should be monitored to ensure that the
device is functioning as intended. If unusual performance characteristics are observed, add i-
tional measures such as changing the align ment or location of the Barkey p lasmatherm may be
necessary.
b
The field strength should be less than 3 V/ m in the frequency range 150 kHz to 80 M Hz.

Portable and mobile rad io sets should
not be used within a distance fro m the
Barkey plas matherm, including cords,
that is less than the recommended
safety distance as calculated by the
relevant equation for the transmit
frequency.
