Guidance and manufacturer's declaration – electromagnetic immunity –
for medical electrical equipment and systems that are not life-supporting
D-LIGHT C model 20 1336 20-1xx is intended for use in the electromagnetic environment specified below.
The customer or user of the D-LIGHT C model 20 1336 20-1xx should ensure that it is used in such an environment.

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

Electromagnetic environment - guidance
Portable and mobile RF communications equipment should be used
no closer to any part of the D-LIGHT C model 20 1336 20-1xx,
including cables, than the recommended separation distance calcu-
lated from the equation applicable to the frequency of the transmitter.
Recommended separation distance:

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 in meters [m].
Field strengths from fixed RF transmitters, as determined by an
