Recommended Separation Distance
This device can be used under the environment that radiated RF disturbances are controlled. User should maintain a minimum
distance between portable and mobile RF communications equipment to prevent electromagnetic interference. Following
recommended distance is calculated according to the maximum output power of the communication equipment.

For transmitters rated at a maximum output power not listed above, the recommended separation distance “d” in meters can
be estimated using the equation applicable to the frequency of transmitter, where “p” is the maximum output power rating of
the transmitter in watts according to the transmitter manufacturer.
Note1: at 80M~800MHz, 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 refection
from structures, objects and people.
2. Overviews
2.1
Indication for Use
XFT-2001EA Foot Drop System is intended to address the lack of ankle dorsiflexion in patients who have sustained damage to
upper motor neurons or pathways to the spinal cord. During the swing phase of walking, the XFT-2001EA electrically stimulates
the appropriate muscles that cause ankle dorsiflexion and may thus improve the individual’s gait. Medical benefits of Functional
Electrical Stimulation (FES) may include prevention/retardation of disuse atrophy, increased local blood flow, muscle
re-education, and maintained or increased joint range of motion.
How does XFT-2001EA Foot Drop System work?
When the leg swings to the angle of threshold, the electrical stimulation will be triggered.
2.3 Features and Innovation
