SPECIFICATIONS AND TECHNICAL INFORMATION: EMC (Electromagnetic Compatibility)
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.

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 reorienting or relocating the
device.

NOTE: If necessary to achieve the immunity test level, the distance between the transmitting antenna and the ME equipment or ME
system may be reduced to 1 m. The 1 m test distance is permitted by IEC 61000-4-3.
