Portable and mobile radio equipment
including cables should not be operated
within a shorter distance to the prisma
VENT AQUA than the recommended
separation distance calculated according
to that which applies to the transmission
frequency.
Recommended separation distance:
d =3.5/3
√ P
d = 3.5/3 √ P

where P is the rated power of the
transmitter in watts (W) according to the
transmitter manufacturer and d is the
recommended separation distance in
meters (m).
