For transmitters rated at a maximum output power not listed above, the recommended separation distance (D) in meters
(m) can be determined 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.
N N o o t t e e 1 1 - At 80 MHz and 800 MHz, the separation distance for the higher frequency range applies.
N N o o t t e e 2 2 - These guidelines may not apply in all situations. Electromagnetic propagation is affected by absorption and
reflection from structures, objects, and people.
The electric lift option, electric litter option, or scale system option is intended for use in the electromagnetic environment
specified below. The customer or the user of the electric lift option, electric litter option, or scale system option should
assure that it is used in such an environment.
