For ME EQUiPMENt and ME SYStEMS that are not LiFE-SUPPortiNG
recommended separation distances between portable
and mobile rF communications equipment and the AD-2040
The AD-2040 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the
AD-2040 can help prevent electromagnetic interference by maintaining
a minimum distance between portable and mobile RF communications
equipment (transmitters) and the AD-2040 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 determined 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.
