Immunity Test
This device is intended for use in the electromagnetic environment specified below. The user of this device should ensure that it is
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
IEC 61000-4-6 150 kHz to 80 MHz
Radiated RF 3 V/m
IEC 61000-4-3 80 MHz to 2.7 GHz
Radiated RF Professional Transport
IEC 61000-4-3 20 V/m
80% AM 1 kHz modulation
80 MHz to 2.7 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.
