3B SCIENTIFIC 3B LASER PEN 200 mW Manuel D'utilisation page 70

The „3B LASER PEN 200 mW" laser system is intended for use in an electromagnetic environment in which radiated RF dis-
turbances are controlled. The customer or the user of the „3B LASER PEN 200 mW" laser system can help prevent electro-
magnetic interference by maintaining a minimum distance between portable and mobile RF communications equipment
(transmitters) and the „3B LASER PEN 200 mW" 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 metres
(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 reflec-
tion from structures, objects and people.
