Guidance and manufacturer's declaration – electromagnetic immunity –
®
The VITOM
3D exoscope model TH 200 is intended for use in the electromagnetic environment specified below.
The customer or user of the device should make sure that it is used in such an environment.
Immunity test
IEC 60601 test level
Conducted RF
3 V
disturbance
150 kHz to 80 MHz
acc. to IEC 61000-4-6
3 V/m
Radiated RF disturbance
acc. to IEC 61000-4-3
80 MHz to 2.5 GHz
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 by 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 device is used exceeds
the applicable RF compliance level above, the device should be observed to verify normal operation. If abnormal performance is observed, additional
measures may be necessary, such as reorienting or relocating the device.
b
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Portable and mobile RF communications equipment should be used
®
no closer to any part of the VITOM
3D exoscope model TH 200,
including cables, than the recommended separation distance calcu-
lated from the equation applicable to the frequency of the transmitter.
Recommended separation distance:
B
B
80 MHz to 800 MHz
E
800 MHz to 2.5 GHz
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 fixed RF transmitters, as determined by an
a
electromagnetic site survey
, should be less than the compliance
