echosens FibroScan 502 touch - Recommended Separation Distances

EE FIBROSCAN 502 TOUCH USER MANUAL FibroScan
NOTE 4: In case of any disturbance in the electromagnetic environment of the FibroScan
502 TOUCHa message is displayed (see the Message Area chapter) and no measurements
can be carried out.
12.4. RECOMMENDED SEPARATION DISTANCES
(Between portable or cellular RF communication devices and the FibroScan 502 TOUCH)
The FibroScan 502 TOUCH is designed for use in an electromagnetic environment in which
RF disturbance is controlled. The customer or the user of the FibroScan 502 TOUCH can
take precautions against interference by maintaining a minimal distance between the portable
or cellular RF communication equipment (transmitters) and the FibroScan 502 TOUCH as
recommended below according to the maximum power of the communicative device.
Maximum Separation distance according to transmitter frequency (m)
transmitter
output power 150 kHz to 80 MHz 80 MHz to 800 MHz 800 MHz to 2.5 GHz
(w) d=3.5/3 VP d= 3.5/3 VP d=7/3 VP
0.01 | 0.12 0.12 0.23
o1 0.37 | 037 ー 0.74
1 1.17 | 1.17 2.33
10 3.69 | 3.69 7.38
100 11.67 | 11.67 23.33
For emitters whose maximum power is not listed above, the recommended separation
distance in meters (m) can be estimated using the applicable equation at the transmitter's
frequency, where P is the maximum transmitter power in watts (W) as specified by the
transmitter manufacturer.
NOTE 1: At 80 MHz and 800 MHz, the separation distance for the highest frequency range is
applicable.
NOTE 2: These recommendations may not be applicable in all cases. Electromagnetic
propagation is affected by absorption and reflection caused by structures, objects and
individuals.
