APPENDIX D – PORTABLE AND MOBILE RF COMMUNICATIONS
Table 4. Recommended separation distances between portable and mobile RF communications equipment
and the ME Equipment or ME System – for ME Equipment and ME Systems that are not Life-Supporting.
Recommended separation distance between
portable and mobile RF communications equipment and the REVIAN RED 101
The REVIAN RED 101 is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The customer or the user of the REVIAN RED 101 can help prevent electromagnetic interference
by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the REVIAN RED 101 as recommended below, according 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 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.
