ELECTROMAGNETIC ENVIRONMENT GUIDANCE
NOTES
The higher frequency range applies at 80 MHz and 800 MHz.
Field strengths from fixed transmitters, such as base stations for radio (cellular/cordless) telephones and land mobile radios, amateur radio, AM and FM radio broadcast and TV broadcast, cannot be
predicted theoretically with accuracy. An investigation of the location is recommended to determine the electromagnetic environment resulting from stationary HF transmitters. If the measured field
strength in the location in which the Gemini 810 + 980 diode laser is used exceeds the applicable RF compliance level above, the Gemini laser unit should be observed to verify normal operation. If
unusual performance characteristics are observed, it may be necessary to take additional measures such as reorientation or repositioning of the Gemini 810 + 980 diode laser.
Over the frequency range 150kHz to 80MHz, field strengths should be less than 3V/m.
WORKING CLEARANCES
The Gemini 810 + 980 diode laser is intended for operation in an electromagnetic environment where radiated HF interference is checked. The customer or the user of the Gemini laser can help prevent
electromagnetic interference by duly observing the minimum distances between portable and/or mobile RF communication devices (transmitters) and the Gemini laser unit. These values may 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, the recommended working clearance d in meters (m) can be determined using the equation in the 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 electromagnetic waves is influenced by their absorption and reflection by buildings, objects and persons.
