Safety advice
3.4.3 Recommended safety distance
The Barkey plas matherm is intended for operation in an electro magnetic environ ment in
which HF interference is controlled. The customer or user of the Barkey plasmatherm can help
avoid electro magnetic interference by observing the minimu m distance between portable an d
mobile HF co mmunications devices (transmitters) and the Barkey plas matherm as stated b e-
low, depending on the output power of the communicat ion device.

For transmitters whose maximu m no minal output is not given in the above table, the recom-
mended safety distance d in metres (m) can be determined using the equation belonging to the
appropriate column, where P is the maximu m no minal output of the transmitter in Watts (W)
as stated by the transmitter manufacturer.
NOTE 1 The higher frequency level applies at 80 M Hz and 800 MHz.
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.
