Floors should be wood, concrete, or
ceramic tile. If floors are covered
with synthetic material, the relative
humidity should be at least 30%.

Portable and mobile radio equip-
ment must not be used within the
recommended working clearance
from the UNIT and its cables, which
is calculated based on the equation
suitable for the relevant transmission
frequency.
