Recommended separation distance between portable and mobile RF communications equipment
and the MEDICAL SCALE
The MEDICAL SCALE M-110 is intended for use in an electromagnetic environment in which
radiated RF disturbances are controlled. The customer or the user of the MEDICAL SCALE M-110
can help prevent electromagnetic interference by maintaining a minimum distance between
portable and mobile RF communications equipment (transmitters) and the MEDICAL SCALE M-110
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.
