Recommended separation distances between portable and mobile
RF communications equipment and the EQUIPMENT or SYSTEM –
for ME EQUIPMENT or ME SYSTEM that are not LIFE-SUPPORTING
The Medical LED Headlight is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of The Medical LED
Headlight can help prevent electromagnetic interference by maintaining a minimum distance
between portable and mobile RF communications equipment (transmitters) and The Medical
LED Headlight 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 meters (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 reflection from structures, objects and people.
Recommended separation distances between portable and mobile RF communications
equipment and The Medical LED Headlight Equipment.
