Note 1 At 80 MHz and 800 MHz the higher frequency range is applied.
Note 2 These guidelines are not applicable in all cases. The propagation of electromagnetic quantities is influenced by the absorption and reflection of buildings,
items and human beings.
a
It is not possible to predict theoretically the field strength of immobile transmitters like base stations of mobile phones and mobile land radio sets, amateur
radio stations, AM and FM television and radio broadcasting transmitters. In order to determine electromagnetic ambient conditions with regard to immobile transmitters a
study of the location should be taken into consideration. If the field strength measured in the place where the laser device is operated exceeds the above mentioned
conformity level the laser device should be watched to proof its function in accordance to the requirements. Unusual performance data may require additional measures,
for instance change of orientation or different location of the laser device.

devices and the laser device without life supporting function
Recommended protective distance between portable and mobile HF-telecommunication devices and the laser device
The laser device is designed for the operation in electromagnetic ambient conditions where HF-disturbance variables are
controlled. Client or user of the laser device can help to avoid electromagnetic disturbances by keeping the minimum distance
between portable and mobile HF-telecommunication devices (transmitters) and the laser device as indicated below, dependent
on the power output of the communication device.

If the maximum power rating for certain transmitters is not given in the above table the recommended protective distance d in
metres (m) can be determined by using the equation indicated in the respective column, where P is the maximum power rating
of the transmitter in Watt (W) according to the manufacturer of the transmitter.

Electromagnetic ambient conditions - guidelines
Portable and mobile radio sets must not be operated in
a distance to the laser device and the leads less than
the recommended protective distance what was
calculated according to the equation for the
transmission frequency.
Recommended protective distance:
d = 1,2 √ P
d = 1,2 √ P for
80 MHz up to 800 MHz
d = 2,3 √ P for
800 MHz up to 2,5 GHz
with P as power rating of the transmitter in Watt (W)
according to data from the manufacturer of the
transmitter and as recommended protective distance in
meter (m).
