SPECIFICATIONS & PERFORMANCE
Guidance and manufacturer's declaration - electromagnetic immunity
The TRC-NW8 is intended for use in the electromagnetic environment specified below.
The customer or the user of the TRC-NW8 should assure that it is used in such an environment.

equipment should be used no closer to any
part of the TRC-NW8, including cables,
than the recommended separation dis-
tance calculated from the equation applica-
ble to the frequency of the transmitter.
Recommended separation distance
where P is the maximum output power rat-
ing of the transmitter in watts (W) accord-
ing 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 compli-
ance level in each frequency range.
b
Interference may occur in the vicinity of
equipment marked with the following sym-
bol:
NOTE 1 At 80 MHz and 800 MHz, 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.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) tele-
phones 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 mea-
sured field strength in the location in which the TRC-NW8 is used exceeds the applicable RF
compliance level above, the TRC-NW8 should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorient-
ing or relocating the TRC-NW8.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
