Guidance and manufacturer's declaration – electromagnetic immunity
The EcoRO Dia I/II (HT) is intended for use in the electromagnetic environment specified below. The customer or the
user of the EcoRO Dia I/II (HT) should assure that it is used in such an environment.

Electromagnetic environment –
guidance
Portable and mobile RF communications
equipment should not be used no closer
to any part of the EcoRO Dia I/II (HT),
including cables, than the recommended
separation distance caculated from the
equation applicable to the frequency of
the transmitter.

Field strengths from fixed RF transmitters,
as determined by an electromagnetic
site survey,
a
should be less than the com-
pliance level in each frequency range.
b
Interference may occur in the
vicinity of equipment marked
with the following symbol:
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 EcoRO Dia I/II (HT) is used exceeds
the applicable RF compliance level above, the EcoRO Dia I/II (HT) should be observed to verify normal operation.
If abnormal performance is observed, additional measures may be necessary, such as reorienting or relocating the
EcoRO Dia I/II (HT).
b
Over the frequency range 150 kHz to 80 MHz, field strength should be less than 10 V/m.
