Guidance and Statement from Manufacturer - Electromagnetic Immunity– for
Equipment and System that are not Life-supporting
The AC-5000 colposcope is intended for use in the electromagnetic environment specified
below. The customer or the user of the AC-5000 colposcope should assure that it is used in such
an environment.

should be used no closer to any part of the AC-5000
colposcope, including cables, than the recommended

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 AC-5000 is used
exceeds the applicable RF compliance level above, The AC-5000 should be observed to
verify normal operation. If abnormal performance is observed, additional measures may be
necessary, such as reorienting or relocating the AC-5000.
 Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
