EMC information

NOTE
• 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.
• Electromagnetic interference may occur in the vicinity of high-frequency electrosurgical equipment and/or other
equipment marked with the following symbol:
• Field strength from fixed RF transmitters as determined by an electromagnetic site survey
a)
should be less than the
compliance level in each frequency range
b)
.
a)Field strength 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 this model is used exceeds the
applicable RF compliance level above, this model should be observed to verify normal operation. If abnormal
performance is observed, additional measures may be necessary, such as re-orienting or relocating this model.
b)Over the frequency range 150 kHz to 80 MHz, field strength should be less than 3 V/m.
Guidance and manufacturer’s declaration - electromagnetic immunity
The OEV262H is intended for use in the electromagnetic environment specified below. The customer or the user of the OEV262H
should assure that it is used in such an environment.
Portable and mobile RF communications equipment should be used no closer to any part of this model, including cables, than the
recommended separation distance calculated from the equation applicable to the frequency of the transmitter.
