Guidance and Manufacture’s Declaration for Electromagnetic Immunity for non-life support systems
The VALO is intended for use in the electromagnetic environment specified below. The customer or user should ensure that it is used in such an environment.
IMMUNITY test
IEC 60601 test level
Compliance level
Electromagnetic environment guidance
Conduction RF
3 Vrms
3 Vrms
Portable and mobile RF communications equipment should be used no
closer to any part of the VALO, including cables, than the recommended
separation distance calculated from the equation applicable to the frequency
of the transmitter.
Recommended separation distance
80 MHz to 800 MHz
800 MHz to 2.5 GHz
P is the maximum output power rating of the transmitter in watts (W) accord-
ing to the transmitter manufacturer and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as determined by an electro-
magnetic site surveya, should be less than the compliance level in each
frequency rangeb.
Interference may occur in the vicinity of equipment marked with the following
symbol:
IEC 61000-4-6
150 kHz to 80 MHz
150 kHz to 80 MHz
Radiated RF
3 V/m
3 V/m
IEC 61000-4-3
80 MHz to 2.5 GHz
80 MHz to 2.5 GHz
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 VALO is used exceeds the applicable RF compliance level above, the VALO should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as re-orienting or relocating the VALO.
b Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
