Recommended separation distance between portable and mobile RF
communications equipment and the MEDICAL SCALE
The MEDICAL SCALE MS4940 is intended for use in an electromagnetic
environment in which radiated RF disturbances are controlled. The customer or
the user of the MEDICAL SCALE MS4940 can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile
RF communications equipment (transmitters) and the MEDICAL SCALE
MS4940 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 metres (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.
NOTE1 At 80 MHz and 800 MHz, the separation distance for the higher
frequency range applies.
NOTE2 These guidelines may not apply in all situations. Electromagnetic
propagation is affected by absorption and reflection from structures, objects
and people.
