Safety advice
Guidelines and manufacturers declaration - Electromagnetic immunity
The Barkey plasmatherm is intended for operation in one of the electromagnetic environ-
ments listed below. The customer or user of the Barkey plasmatherm must ensure that it is
operated in one of these environments.

Portable and mobile radio sets should
not be used within a distance from the
Barkey plasmatherm, including cords,
that is less than the recommended
safety distance as calculated by the
relevant equation for the transmit
frequency.

Interference is possible near devices
that display 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 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 television transmissions cannot be
accurately theoretically determined in advance. You should consider carrying out a site survey
to determine the electromagnetic environment 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 plasmatherm should be monitored to ensure that the
device is functioning as intended. If unusual performance characteristics are observed, addi-
tional measures such as changing the alignment or location of the Barkey plasmatherm may be
necessary.
b
The field strength should be less than 3 V/m in the frequency range 150 kHz to 80 MHz.
