12 Electromagnetic Compatibility (EMC)
Recommended safe clearances between portable and mobile HF
telecommunication devices and the TNI
®
device
The TNI
®
device is designed for operation in an electromagnetic environment
specified below in which the HF interference is controlled. The customer or
the user of the TNI
®
device can help to avoid electromagnetic interference by
observing the minimum distance shown below between portable and mobile HF
telecommunication devices (transmitters) and the TNI
®
device - depending on the
output power of the communication device.

For transmitters whose maximum rated output is not listed in the above table,
the recommended safe clearance
d
in meters (m) can be determined using the
equation belonging to the appropriate column, with
P
being the maximum rated
power of the transmitters in Watt (W) as specified by the manufacturer of the
transmitter unit.
NOTE 1 The higher frequency range applies to 80 MHz and 800 MHz.
NOTE 2 These guidelines may not be applicable in all instances. The spread
of electromagnetic variables is influenced by absorption and reflection from
buildings, objects and people.
