Technical Specification – Sectra MicroDose Mammography L30, Software 8.3
Electromagnetic immunity
Portable and mobile RF
communications equipment should be
used no closer to any part of the L30,
including cables, than the
recommended separation distance
calculated from the equation
applicable to the frequency of the
transmitter.
Conducted disturbances
induced by RF fields
IEC 61000-4-6.
(V1)
V1 =10 V and 80%
AM modulation
with 1 kHz at
frequency range
0,15 – 80 MHz
Radiated disturbances
induced by RF fields
IEC 61000-4-3
(E1)
10 V/m and 80%
AM modulation
with 1 kHz at
frequency range
80-2500 MHz
E1 = 10 V/m
Recommended separation distance
P = maximum output power rating of
the transmitter in watts (W) according
to the transmitter manufacturer
d = recommended separation distance
in metres (m)
Field strengths from fixed RF
transmitters, as determined by an
electromagnetic site survey3 should be
less than the compliance level in each
frequency range. 4
Interference may occur in the vicinity
of equipment marked with the
following symbol:
Voltage dips, short
interruptions and voltage
variations on power supply
input lines
IEC 61000-4-11
>95% dip for 10
ms. 60% dip for 100
ms. 30% dip for 500
ms.
Power loss may result in unwanted
power off of model L30. In such cases
re-calibration of the system is
necessary.

Note: 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 L30 is used exceeds the applicable RF compliance level above, the
L30 should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the L30.
4
Note: Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 10 V/m.
