
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3V/m.
Recommended separation distances between portable and mobile RF
communications equipment and the AM-2000
The AM-2000 surgical microscope is intended for use in an electromagnetic environment in
which radiated RF disturbances are controlled. The customer or the user of the AM-2000
surgical microscope can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the
AM-2000 surgical microscope as recommended below, according to the maximum output power
of the communications equipment

For transmitters rated at a maximum output power not listed above the recommended
separation distance d in metres (m) can be estimated using 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.

At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.

These guidelines may not apply in all situations. Electromagnetic propagation is affected by
absorption and reflection from structures, objects and people.
AM-2000 surgical microscope has been tested in accordance with YY 0505-2012/ IEC
60601-1-2:2014, which cannot be guaranteed against electromagnetic interference in any way, and
should avoided to be in a high electromagnetic environment.
