Recommended separation distances between portable and mobile RF communications equipment
and the
Propex IQ
®
Apex Locator
The
Propex IQ
®
Apex Locator is intended for use in the electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
Propex IQ
®
Apex
Locator can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the
Propex IQ
®
Apex Locator as recommended below, according to the maximum output power of the
communication 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 separation distance for the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is affected
by absorption and reflection from structures, objects and people.
Note 3: An additional factor of 10/3 is used in calculating the recommended separation distance to
decrease the likelihood that mobile / portable communications equipment could cause interference
if it is inadvertently brought into patient areas.
