ENGLISH
Guidance and Manufacturer's Declaration – Electromagnetic Immunity
The SwiSto3 is intended for use in the electromagnetic environment specified below. The customer or user of the SwiSto3 is
to assure that it is used in such an environment.
IEC 60601
Immunity test
test level
Conducted RF 3 Vrms
IEC 61000-4-6 150 kHz to
80 MHz
3 V/m
Radiated RF
80 MHz to
IEC 61000-4-3
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 SwiSto3 device is used exceeds the applicable RF compliance level
above, the SwiSto3 device 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.

Compliance
Electromagnetic environment – guidance
level
Portable and mobile RF communications equipment should be
used no closer to any part of the SwiSto3 device, including cables,
than the recommended separation distance, which is calculated
using the equation for the frequency transmission.
3 Vrms Recommended separation distance
d = 1.2√P
3V/m d = 1.2√P for 80 MHz to 800 MHz
d = 2.3√P for 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 meters (M).
Field strengths (a) from fixed RF transmitters, as determined by an
electromagnetic site survey, should be less than the compliance
level (b) in each frequency range.
Interference may occur in the vicinity of equipment marked with
the following symbol:
