Appendix A: Electromagnetic Emissions and Immunity
Recommended separation distances between portable and mobile RF communications equipment
®
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
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.
