guidelines
Floors should be wood, concrete, or
ceramic tile. If the floor is covered
with synthetic material, the relative
humidity must be at least 30%.
The quality of the line power supply
should be that of a typical commer-
cial or hospital environment.

with P as the power rating of the
transmitter in watts (W) according to
the transmitter manufacturer's speci-
