MIR Spirolab (UK version) | User Manual
Manufacturer’s recommendations and declarations - electromagnetic immunity
The Spirolab device can be used in the following electromagnetic environments.
The Spirolab customer or end user must ensure that the device is used in such an environment.
RF conduit
IEC 61000-4-6
RF radiated
IEC 61000-4-3
3 Vrms
150 kHz to 80 MHz
3 V/m 80 MHz to
2.5 GHz
[3 ] V
[3 ] V/m
RF and mobile communication items of equipment must not be used any
closer the separation distance recommended by SPIROLAB including ca-
bles as calculated using the equation applicable to the frequency of the
transmitter.
Recommended separation distance:
d=[ 3.5 ] √P
3
d=[ 3.5 ] √P 80 MHz at 800 GHz
3
d=[ 7 ] √P 800 MHz at 2.5 GHz

Where P is the maximum nominal distance of the transmitter in Watts (W)
according to the transmitter manufacturer and d is the recommended
separation distance in metres (m). The intensity of the fixed RF transmit-
ters, as determined by an electromagnetic scan of the site, could be lower
than the level of conformity in each frequency interval (b). Interference
near the device may be detected from devices marked with the following
symbol:
NOTE 1: at 80 MHz and 800 MHz, the highest frequency interval is applied.
NOTE 2: These guide lines may not apply for all situations. The propagation of electromagnetism is influenced by the absorption and
reflection of structures, objects and persons.
A) The intensities of fixed transmitter fields such a telephone base stations (mobiles and cordless), terrestrial radio equipment, amateur
radio appliances, AM and FM radio and TV transmitters cannot be theoretically accurately predicted. To assess an electromagnetic
environment generated by fixed RF transmitter, you need to perform an electromagnetic scan of the site. If the intensity of the field
where the Spirolab is used exceeds the applicable conformity level mentioned above, you will need to observe how the Spirolab works under
normal conditions. If you detect faulty performance, you may need to implement additional measures such as changing the direction or position of
the Spirolab.
B) The intensity of the field in the frequency interval from 150 kHz to 80 MHz should be less than [3] V/m
