Guidance and manufacturer's declaration - Electromagnetic Immunity
The product is intended for use in the electromagnetic environment specified below. The customer or the user of the product should assure that it is used in such an environment.
Immunity test EN/IEC60601 test level
Conducted RF 3Vrms
EN/IEC61000-4-6 150kHz to 80MHz
Radiated RF 3V/m
EN/IEC61000-4-3 80MHz to 2.5GHz
NOTE1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE2: 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 product is used exceeds the applicable RF compliance level stated above, the product should be observed
to verify normal operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the product.
b: Over the frequency range 150kHz to 80MHz, the field strength should be less than 3V/m.

Recommended separation distances between portable and mobile RF communications equipment and the product
The product is intended for use in an electromagnetic environment in which radiated RF disturbances are controlled. The customer or the user of the product can help prevent
electromagnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment (transmitters) and the product 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 estimated 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.
NOTE1: At 80MHz and 800MHz, the higher frequency range applies.
NOTE2: These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and reflection from structures, objects and people.

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be
used no closer to any part of the product, 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 80MHz to 800MHz
d = 2.3 P 800MHz to 2.5GHz
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 from fixed RF transmitters as determined by an
(a)
electromagnetic site survey should be less than the
compliance level in each frequency range
