SDC MLD-810 Manuel D'utilisation page 47

The MLD-810 Class IV Soft-Tissue Diode Laser System is intended for use in the
electromagnetic environment specified below. The customer or the user of the
Model MLD-810 should assure that it is used in such an environment.

NOTE 1: At 80 MHz, the higher frequency range applies.
NOTE 2: These guidelines may not apply in all situations. Electromagnetic propagation is
affected by absorption and reflection from 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, and electromagnetic site survey should be
considered. If the measured field strength in the location in which the MLD-810 is used
exceeds the applicable RF compliance level above, the MLD-810 should be observed to
verify normal operation. If abnormal performance is observed, the additional measures may
be necessary, such as re-orienting or relocating the MLD-810.
b) Over the frequency range of 150 kHz to 80 MHz, field strengths should be less than 3 V/m.

Level Environment — Guidance
Portable and mobile RF
communications equipment should
be used no closer to any part of
the MLD-810, including cables,
than the recommended separation
distance calculated from the equation
applicable to the frequency of the
transmitter.
Recommended separation distance
d=1,2√P 150 kHz to 80 MHz
3 V/m
d=1,2√P 80 MHz to 800 MHz
d=2,3√P 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 metres (m). Field strengths from
fixed RF transmitters, as determined
by and electromagnetic site survey, a
should be less than the compliance
level in each frequency range.
Interference may occur in the vicinity
of equipment containing a transmitter.
