Guidance and manufacturer’s declaration – electromagnetic
immunity
The Dash 3000/4000/5000 is intended for use in the electromagnetic
environment specified below. It is the responsibility of the customer or
user to assure that the Dash 3000/4000/5000 is used in such an
environment.
Immunity test IEC 60601 test level Compliance level Electromagnetic environment – guidance
Portable and mobile RF communications equipment should not
be used closer to any part of the equipment, including cables,
than the recommended separation distance calculated from the
equation applicable to the frequency of the transmitter.
Recommended separation distance
Conducted RF
IEC 61000-4-6
3 Vrms
150 KHz to 80 MHz
3 V rms
d = 1.2
Radiated RF
IEC 61000-4-3
3 V/m
80 MHz to 2.5 GHz
3 V/m
d = 1.2 80 MHz to 800 MHz
d = 2.3 800 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:
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 reflection from structures, objects,
and people.
a
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile 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 equipment is used exceeds the applicable RF compliance level above,
the equipment should be observed to verify normal operation. If abnormal performance is observed, additional measures
may be necessary, such as re-orienting or relocating the equipment.
b
Over the frequency range 150 KHz to 80 MHz, field strengths should be less than 3 V/m.
Note 3: For values above 2.5GHz, IEC 60601-1-2, Subclause 5.2.2.2 states “frequencies above 800MHz can use k= 7.
