Guidance and Manufacturer’s Declaration - Electromagnetic Emissions
e model VisiClear™ is intended for use in the electromagnetic environment specied below.
e customer or user of the model VisiClear™ should assure that it is used in such an environment.
Immunity Test
IEC 60601
Test Level Compliance Level Electromagnetic Environment - Guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the Model EVL including cables,
than the Recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.

Where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from xed RF transmitters,
as determined by an electromagnetic site
survey, should be less than the compliance
level in each frequency range.
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: ese guidelines may not apply in all situations. Electromagnetic propagation is aected by absorption
and reection from structure, objects and people.
Field strengths from xed 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 xed RF transmitters, an electromagnetic site
survey should be considered. If the measured eld strength in the location in which the Model EVL is used
exceeds the applicable RF compliance level above, the model VisiClear™ should be observed to verify normal
operation. If abnormal performance is observed, additional measures may be necessary, such as reorienting or
relocating the model VisiClear™.
Over the frequency range 150 kHz to 80 MHz, eld strengths should be less than 3 V/m.
