than the recommended separation distance
calculated from the equation applicable to
the frequency of the transmitter.
Recommended Separation Distance:
d = 1.17√P
d = 1.17√P 80 MHz to 800 MHz
d = 2.33√P 800 MHz to 2.5 GHz
where P is the maximum output power
rating of the transmitter in watts (W)
according to the transmitter manufacturer
and d is the recommended separation
distance in meters (m).
Field strengths from fixed RF transmitters, as
determined by an electromagnetic site
survey (a), should be less than
thecompliance level in each frequency
range(b).
Interference may occur in the vicinity of
equipment marked
with the following symbol:
NOTE 1: At 80 MHz and 800 MHz, 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.
(a) 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. To assess the electromagnetic environment due to fixed RF transmitters, an electromagnetic site
survey should be considered. If the measured field strength in the location in which 32” 4K Surgical Display is
used exceeds the applicable RF compliance level above, the display and transmitter should be observed to verify
normal operation. If abnormal performance is observed, additional measures may be necessary, such as
reorienting or relocating the display.
(b) Over the frequency range 150 kHz to 80 MHz, field strengths should be less than 3 V/m.
Recommended Separation Distances Between Portable and Mobile RF Communications Equipment and 32”
4K Surgical Display
The display is intended for use in an electromagnetic environment in which radiated RF disturbances are
controlled. The user of the display can help prevent electromagnetic interference by maintaining a minimum
distance between portable and mobile RF communications equipment (transmitters) and the display as
recommended below, according to the maximum output power of the communications equipment.
