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.

LEVEL ENVIRONMENT GUIDANCE
Portable and mobile radio equip-
ment must not be used within the
recommended
from the Gemini laser unit and its
cables, which is calculated based on
the equation suitable for the rele-
vant transmission frequency.
Recommended separation distance
d= [1.2] √P
d= [1.2] √P at 80 MHz to 800 MHz
d= [2.3] √P at 800 MHz to 2.5 GHz
where P is the nominal transmitter
output in watts (W) specified by the
transmitter manufacturer and d is
the recommended working clearance
in meters (m).
