Portable and mobile RF communications equipment
should be used no closer to any part of the Dynatron
900+ (and accessories), 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 meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site survey,
should be less than the compliance level in each
frequency range
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 to 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 Dynatron 900+ (and accessories) is
used exceeds the applicable
RF compliance level above, the Dynatron 900+ (and accessories) should be observed to verify normal operation. If
abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
Dynatron 900+ (and accessories).
b. Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
Guidance and Manufacturer's Declaration - Electromagnetic Immunity
The Dynatron 900+ (and accessories) is intended for use in the electromagnetic environment specified below. The
customer or the user of the Dynatron 900+ (and accessories) should assure that it is used in such an environment.
