Human NIBP Nano
Owner’s Guide
Recommended separation distances between portable and mobile
RF communications and the Human NIBP Nano Interface
The Human NIBP Nano Interface is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the Human NIBP Nano Interface can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the Human NIBP Nano
Interface 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 metres (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 refl ection from structures, objects and people.
ADInstruments reserves the right to alter these specifications at any time.
