Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The dynatron 25 series (and accessories) is intended for use in the electromagnetic environment speci-
fied below. The customer or the user of the Dynatron 25 Series (and accessories) 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 dynatron
25 series (and accessories), including cables, than the
recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
recommended separation distance
d = 1.17 x P 80 mhz to 800 mhz
d = 1.17 x P 800 mhz to 2.5 ghz
where P is the maximum output power rating of the trans-
mitter in watts (W) according to the transmitter manufac-
turer 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 pre-
dicted theoretically with accuracy. To assess the electromagnetic environment due to fixed RF transmit
-
ters, an electromagnetic site survey should be considered. If the measured field strength in the location
in which the dynatron 25 series (and accessories) is used exceeds the applicable
rf compliance level above, the dynatron 25 series (and accessories) should be observed to verify nor-
mal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the dynatron 25 series (and accessories).
b. Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
