portable and mobile RF communications equipment and the TD-3128
The TD-3128 is intended for use in an electromagnetic environment (for home and
professional healthcare) in which radiated RF disturbances are controlled. The customer
or the user of the TD-3128 can help prevent electromagnetic interference by maintaining a
minimum distance between portable and mobile RF communications equipment (transmitters)
and the TD-3128 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.
