10 Manufacturer’s declaration regarding electromagnetic compatibility
Recommended separation distances between portable and mobile RF communications
equipment and the SIROLaser
The SIROLaser model is intended for use in an electromagnetic environment in which radiated RF disturbances are con-
trolled. The customer or user can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the SIROLaser 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 meters
can be determined using the equation applicable to the frequency of the transmitter, where “P” is the maximum output
power rating of the transmitter in watt according to the transmitter manufacturer.
Remarks:
At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
(2) These guidelines may not apply in all cases. Electromagnetic propagation is affected by absorption and reflection from
structures, objects, and people.
