Guidance and manufacturer's declaration
electromagnetic immunity
The DEVICE is intended for use in the electromagnetic environment specified below. The customer or the user of
the DEVICE should assure that it is used in such an environment.
Immunity IEC 60601 Compliance
Electromagnetic environment – guidance
test test level level
Portable and mobile RF communications equipment should be used no
closer to any part of the DEVICE, including cables, than the recommended
separation distance calculated from the equation applicable to the
frequency of the transmitter.

IEC 61000- MHz to 2.5 3 V/m (W) according to the transmitter manufacturer and d is the recommended
4-3 GHz separation distance in meters (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, the DEVICE should
be observed to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as
re-orienting 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 DEVICE
The DEVICE is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The customer or the user of the DEVICE can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters) and the DEVICE as
recommended below, according to the maximum output power of the communications equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance d in meters (m) can be determined
using the equation applicable to the frequency of the transmitter, where P is the maximum output power rating of the transmitter in watts (W)
according to the transmitter manufacturer.
NOTE 1 At 80 MHz and 800 MHz, the separation distance for 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.
