ELECTROMAGNETIC ENVIRONMENT GUIDANCERATED MAXIMUM OUTPUTPOWER OF TRANSMITTER [W]WORKING CLEARANCE ACCORDING TO TRANSMISSION FREQUENCY [M]WORKING CLEARANCESThe Gemini 810 + 980 diode laser is intended for operation in an electromagnetic environmentwhere radiated HF interference is checked. The customer or the user of the Gemini laser can helpprevent electromagnetic interference by duly observing the minimum distances between portableand/or mobile RF communication devices (transmitters) and the Gemini laser unit. These valuesmay vary according to the output power of the relevant communication device as specified below.For transmitters whose maximum nominal output is not specified in the above table, therecommended working clearance d in meters (m) can be determined using the equation inthe corresponding column, where P is the maximum nominal output of the transmitter in watts (W)specified by the transmitter manufacturer.Remark 1: The higher frequency range applies at 80 MHz and 800 MHz.Remark 2: These guidelines may not be applicable in all cases. The propagation of electromagneticwaves is influenced by their absorption and reflection by buildings, objects and persons.150 KHZ TO 80 MHZd= [1.2] √P0.01 0.12 0.12 0.230.1 0.38 0.38 0.731 1.2 1.2 2.310 3.8 3.8 7.3100 12 12 23d= [1.2] √P d= [2.3] √P80 MHZ TO 800 MHZ 800 MHZ TO 2.5 GHZ48 |
