Electromagnetic Environment - Guidance
Portable and mobile RF communications
equipment should be used no closer to any
part of the Optional Electric Lift or Electric
Litter and Optional Scale System, including
cables, than the recommended separation
distance calculated from the equation
appropriate for the frequency of the
Recommended Separation Distance
80 MHz to 800 MHz
800 MHz to 2.7 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
Field strengths from fixed RF transmitters,

Mains power quality should
be that of a typical
commercial or hospital
environment. If the user of
the optional electric lift or
electric litter requires
continued operation during
power mains interruptions,
it is recommended that the
device be powered from an
uninterrupted power supply
or a battery.
Power frequency magnetic
fields should be at levels
