Prorelax TENS + EMS SUPER DUO PLUS Operating Instructions Manual page 162

Recommended separation distances between portable and mobile RF communications
equipment and the TENS+EMS SUPER DUO
The TENS+EMS SUPER DUO is intended for use in an electromagnetic environment
in which radiated RF disturbances are controlled. The customer or the user of the
TENS+EMS SUPER DUO help prevent electromagnetic interference by maintaining a
minimum distance
between portable and mobile RF communications equipment (transmitters) and the
TENS+EMS SUPER DUO 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 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.
