The Optional Electric Lift/Litter and Optional Scale System is suited for use in the electromagnetic
environment specified below. The customer or the user of the Optional Electric Lift/Litter and Optional
Scale System should ensure that it is used in such an environment.

Portable and mobile RF communications equipment should be
used no closer to any part of the Optional Electric Lift/Litter and
Optional Scale System, including cables, than the recommended
separation distance calculated from the equation appropriate for
the frequency of the transmitter.
Recommended Separation Distance
d=1,2√P
d=1,2√P
80 MHz to 800 MHz
d=2,3√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 metres (m).
Field strengths from fixed RF transmitters, as determined by an
electromagnetic site survey,
a
should be less than the compliance
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 the Optional Electric Lift/Litter and
Optional Scale System is used exceeds the applicable RF compliance level above, the Optional Electric Lift/Litter
and Optional Scale System should be observed to verify normal operation. If abnormal performance is observed,
additional measures may be necessary, such as reorienting or relocating the Optional Electric Lift/Litter and Optional
Scale System.
b
Over the frequency range 150 kHz to 80 MHz, field strengths are less than 3 V/m.
