Guidance and manufacturer's declaration - electromagnetic immunity
Model POC-W181 is intended for use in the electromagnetic environment specified below. The
customer or the user of the model POC-W181 should assure that it is used in such an environ-
ment.

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) tele-
phones 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 mea-
sured field strength in the location in which the model POC-W181 is used exceeds the applica-
ble RF compliance level above, the model POC-W181 should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such
as reorienting or relocating the model POC-W181.

Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

W181, including cables, than the recom-
mended separation distance calculated
from the equation applicable to the fre-
quency of the transmitter.
