Immunity Test IEC 60601 Test Level Compliance Level Electromagnetic Environment—Guidance
This device is intended for use in the electromagnetic environment specified below. The user of this device
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.
Conducted RF 3 Vrms

80 MHz to 2.5 GHz
Notes:
• At 80 MHz and 800 MHz, the higher frequency range applies.
• 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 reorienting or relocating
the device.
b. Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

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 electromagnetic site
a
survey, should be less than the compliance
level in each frequency range.
