Recommended separation distances between portable and mobile RF communications
equipment and the Optional Electric Lift/Litter and Optional Scale System.
The Optional Electric Lift/Litter and Optional Scale System is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or the user of the Optional
Electric Lift/Litter and Optional Scale System can help prevent electromagnetic interferences by maintaining
a minimum distance between portable and mobile RF communications equipment (transmitters) and the
Optional Electric Lift/Litter and Optional Scale System 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.
