If display is distorted, it may be
necessary to position the Model
Myolift QT. Further from sources of
power frequency magnetic fields or
to install magnetic shielding. The
power frequency magnetic field
should be measured in the intended
installation location to assure that it
is sufficiently low.
NOTE: UT is the a.c mains voltage prior to application of the test level.
Recommended Separation Distances Between Portable and Mobile RF
Communications Equipment and the Myolift QT System
The Myolift QT device is intended for use in an electromagnetic environment in which radiated RF
disturbances are controlled. The user of the Myolift QT device can help prevent electromagnetic
interference by maintaining a minimum distance between portable and mobile RF communications
equipment (transmitters) and the Myolift QT device 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 a ff ected by
absorption and reflection from structures, objects, and people.
