Guidance and Manufacturer's Declaration: Electromagnetic Immunity
Norlase Leaf is intended for use in the electromagnetic environment specified below. The
customer or the user of the laser system should ensure that it is used in such an environment.

Portable and mobile RF
communications equipment should be
used no closer to any part of the laser
system, including its cables, than the
recommended separation distance
calculated from 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 and d is the
recommended separation distance in
meters (m).
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(b).
Interference may occur in the vicinity of
equipment marked with the following
symbol:
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 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, an electromagnetic site survey should be considered. If the measured field
Strength in the location in which the laser system is used exceeds the applicable RF compliance level
above, the laser system should be observed to verify normal operation. If abnormal performance is
observed, additional measures may be necessary, such as reorienting or relocating the laser system.
(b)
Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
