Guidance and manufacturer’s declaration – electromagnetic immunity
The model PT 200 is intended for use in the electromagnetic environment specified below. The
customer or the user of the model PT 200 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 model
PT 200, including cables, than the recommended
separation distance calculated from the equation
applicable to the frequency of the transmitter.
Recommended separation distance
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 metres (m).b
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,a
should be less than the compliance level in each
frequency range. b
Interference may occur in the vicinity of equipment
marked with the following symbol:
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)
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 model PT 200 is used exceeds the applicable RF compliance
level above, the model PT 200 should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating
the model PT 200.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
