GENERAL INFORMATION ON USAGE AND MAINTENANCE
Guidance and manufacturer's declaration - electromagnetic immunity
The TRK-2P is intended for use in the electromagnetic environment specified below.
The customer or the user of the TRK-2P should assure that it is used in such an environment.

Portable and mobile RF communications equipment should be
used no closer to any part of the TRK-2P, including cables, than
the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
d = 1.2
d = 1.2 80MHz to 800MHz
d = 2.3 800MHz to 2, 5GHz
where P is the maximum output power rating of the transmitter
in watts (W) according to the transmitter manufacturer and d is
the recommended separation distance in meters (m).
Field strengths from fixed RF transmitters, as determined by
an electromagnetic site survey, a should be less than the com-
pliance level in each frequency range. b
Interference may occur in the vicinity of equipment marked with the
following symbol:
NOTE 1
NOTE 2
At 80 MHz and 800 MHz, the higher frequency range applies.
These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorp-
tion and reflection from structures, objects and people.
a Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land
mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast cannot be predicted theoretically
with accuracy. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic
site survey should be considered. If the measured field strength in the location in which the TRK-2P is used
exceeds the applicable RF compliance level above, the TRK-2P should be observed to verify normal opera-
tion. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relo-
cating the TRK-2P.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
