Recommended separation distances between portable and mobile RF communication equipment and the
TRENDvent
ventilator
The TRENDvent ventilator is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled.
The user
1
of the TRENDvent ventilator can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the TRENDvent ventilator as recommended below, accord-
ing to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance
d in meters (m) can
be estimated using the equation applicable to the frequency of the transmitter, where
P is the maximum output power rating of the
transmitter in watts (W) according to the transmitter manufacturer.
Note 1 At 80 MHz and 800 MHz the higher frequency range is essential.
Note 2 These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and re
fl
ection
from structures, objects and people.
