Guidance and Statement from Manufacturer - Electromagnetic Immunity– for
EQUIPMENT and SYSTEM that are not LIFE-SUPPORTING
The AM-2000 surgical microscope is intended for use in the electromagnetic environment
specified below. The customer or the user of the AM-2000 surgical microscope 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 the AM-2000 surgical
microscope, including cables, than the recommended
separation distance calculated 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
compliance level in each frequency range.
Interference may occur in the vicinity of equipment marked
with the following symbol:

At 80 MHz and 800 MHz, the higher frequency range applies.

These guidelines may not apply in all situations. Electromagnetic is affected by absorption
and reflection from structures, objects and people.

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 AM-2000 is used
exceeds the applicable RF compliance level above, The AM-2000 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the AM-2000.
