HNS 12
Stimuplex
®
HNS12 is intended for operation in an electromagnetic environment in which RF disturbances are controlled. The
user of the Stimuplex ® HNS 12 can help prevent electromagnetic malfunctions by maintaining a minimum distance between
portable and mobile RF telecommunications equipment (transmitters) and the Stimuplex
®
HNS 12, dependent on the output
power of the communications equipment as listed below.

For transmitters whose maximal rated power is not listed in the table above, the recommended separation distance d in meters
(m) can be calculated by applying the equation that belongs to each column, where P is the maximum rated power of the
transmitter in watts (W) as stated in the transmitter ’s information.
Remark 1:
At 800 MHz, the separation distance for the higher frequency range applies.
Remark 2: These guidelines may not apply in all cases. The distribution of electromagnetic fields is affected by absorptions
and reflections of buildings, objects and persons
