Recommended separation distances between portable and mobile RF communications equipment and the NU-IP40S
The NU-IP40S is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer
or the user of the NU-IP40S can help prevent electromagnetic interference by maintaining a minimum distance between portable and
mobile RF communications equipment (transmitters) and the NU-IP40S as recommended below, according to the maximum output
power of the communications equipment.

For transmitters rated a maximum output power not listed above, the recommended separation distance in meters (m) can be
estimated using the equation applicable to the frequency of the transmitter, where 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.
Caution
When you dispose of the unit or accessories, you must
obey the laws in the relative area or country and the
regulations in the relative hospital regarding
environmental pollution.
