Guidance and Manufacturer’s Declaration - Electromagnetic Immunity
The Dynatron ibox is intended for use in the electromagnetic environment specified below.
The customer or the user of the Dynatron ibox should assure that it is used in such an environment.
Immunity Test
IEC 60601
Test Level
Compliance
Level
Electromagnetic Environment - Guidance
Conducted RF
IEC 61000-4-6 3 Vrms
150 kHz to 80 MHz
Not
Applicable
Portable and mobile RF communications equipment should be used no closer to any part of
the Dynatron ibox, 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 = 2.33 x P 800 MHz to 2.5 GHz
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 compliance level in each frequency range.
b
Interference may occur in the vicinity of equipment marked with the following symbol:
Conducted RF
IEC 61000-4-6
Radiated RF
EN55011
Not Applicable
3 V/m
80 MHz to 2.5 GHz
Not
Applicable
3 V/m
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 ibox is used exceeds the applicable RF compliance level above, the Dynatron ibox should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the device.
b. Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
