Recommended separation distances between portable and mobile
RF communications
equipment and the 1101
This Model 1101 is intended for use in the electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of
the 1101 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications
equipment (transmitters) and the 1101 as recommended below, according
to the maximum output power of the communications.

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 manufactuer.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
NOTE2 These gudelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects and people.
800 MHz to 2.5 GHz
d = 2.3 P
80 MHz to 800 MHz
d = 1.2 P
150 kHz to 80 MHz
d = 1.2 P
