Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and Norlase Leaf
Norlase Leaf is intended for use in an electromagnetic environment in which radiated RF disturbances
are controlled. The user of the laser system can help prevent electromagnetic interference by
maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the laser system 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 (m) can be estimated using 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.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for 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.
Complies with 21 CFR 1040.10 and 1040.11 except for deviations pursuant to Laser Notice No 50,
dated June 24, 2007.
Unexpected electromagnetic waves or other electronic interference may cause an unexpected system
response that results in a potentially dangerous condition. Do not use this device if abnormal operation is
observed in the presence of other equipment.
