Guidance and manufacturer's declaration - electromagnetic immunity
The BY 40 Breast Pump is designed to be operated in the electromagnetic environment described below. The client or
user of the BY 40 Breast Pump must ensure that the product is used in such environment.
Immunity test
Conducted RF
IEC 61000-4-6
Irradiated RF
IEC 61000-4-3
NOTE 1: For 80MHz and 800MHz, the highest frequency interval is applied.
NOTE 2: These guidelines cannot always be applied. Electromagnetic propagation is altered by absorption and refl
ection of facilities, objects and people.
a. For field intensity of fi xed transmitters, such as the base stations for radiophones (cellular and cordless) EN and
terrestrial radiophones, radio amateur equipment, AM and FM radio and TV transmitters whose presence ca not
be foreseen an on-site electromagnetic test should be planned. If fi eld intensity measured where the BY 40 Bre-
ast Pump is used exceeds the RF conformity level then the BY 40 Breast Pump has to be kept under control to
check for its correct operation. If anomalies are detected, additional measures can be taken such as a reorienting
or repositioning of the BY 40 Breast Pump
b. Over the frequency interval of 150kHz - 80MHz, field intensity has to be lower than 3V/m.

RF portable and mobile communica-
tion equipment should not be used
closer than the separation distance
calculated through the equation appli-
cable to the transmitter frequency to
any part of the BY 40 Breast Pump,
Cables included. Recommended se-
paration distances.
d = 1.17 P
d = 4 Pda 80 MHz to 800 MHz
d = 2.33 P 800 MHz to 2.5 GHz
where P is the maximum rated Watt
(W) power from the transmitter as
declared by the manufacturer while
d is the recommended separation
distance expressed in metres (m).
Field intensity produced by fixed RF
transmitters, as set by electromagne-
tic test on site a, should be lower than
the conformity level of every frequen-
cy interval. b Interferences nearby the
