GENERAL INFORMATION ON USAGE AND MAINTENANCE
Guidance and manufacturer's declaration - electromagnetic immunity
The TRK-3 OMNIA is intended for use in the electromagnetic environment specified below.
The customer or the user of the TRK-3 OMNIA should assure that it is used in such an environment.

a)
Portable and mobile RF communications
equipment should be used no closer to any
part of the TRK-3 OMNIA, including cables,
than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended separation distance
d =
where P is the maximum output power rating
of the transmitter in watts (W) according to
the transmitter manufacturer, d is the recom
-
mended separation distance in meters (m),
and E is the radiation electromagnetic field
level in volt/meter (V/m).

The exterior surface of the TRK-3 OMNIA
should be kept at least 0.15 m from RF emit-
ters such as RFID readers.
NOTE 1
These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
