OPTIONAL ELECTRIC LIFT/LITTER AND OPTIONAL SCALE SYSTEM(CONTINUED)
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 .
IEC 60601
Immunity Test
Test Level
Conducted RF 3 Vrms
IEC 61000- 150 kHz to 80 MHz
4-6 *
3 V/m
Radiated RF 80 MHz to 2,5 GHz
IEC 61000-4-3
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 .
* Applies to Optional Electric Lift/Litter only

EMC Information
Compliance
Electromagnetic Environment - Guidance
Level
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
3 Vrms
3 V/m
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) .
