GUIDANCE AND MANUFACTURER’S DECLARATION – ELECTROMAGNETIC IMMUNITY
The ACRL-3100 is intended for use in the electromagnetic environment specified below. The user of the ACRL-3100 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
Radiated RF
IEC 61000-4-3
Not Applicable
3 V/m
80 MHz to
2.6 GHz
3 V/m
Portable and mobile RF communications equipment should be
used no closer to any part of the ACRL-3100, including cables,
than the recommended separation distance calculated from
the equation applicable to the frequency of the transmitter.
Recommended separation distance
d
= 1,2 √P
d
= 1,2 √P 80 MHz to 800 MHz
d
= 2,3 √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 metres (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 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 device is used exceeds the applicable RF
compliance level above, 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.
Recommended separation distances between portable and mobile RF communications equipment and the ACRL-3100
The ACRL-3100 is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The
customer or the user of the ACRL-3100 can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and the ACRL-3100 as recommended below,
according to the maximum output power of the communications equipment.
