SAFETY PRECAUTIONS
• When the battery charge is low, proprio foot ® will return to the last preset heel height position. A warning
signal will occur (see “Charging and power” ).
• When making adjustments to proprio foot ® ensure the user is seated or in a stable standing position.
• The user should stop walking immediately if alarm signals are felt or heard. Proceed to walk with caution.
• do not use proprio foot ® while the battery is charging. Be sure to disconnect it from the charger prior to
putting on the prosthesis.
• Improper handling or adjustment of proprio foot ® may cause malfunction that may subject the user to the
risk of falling.
• High-impact activity and sports, excessive loading, and heavy-duty use should be avoided.
• avoid impact to the battery.
•
ensure
that the battery connection cable does not interfere with the actuator motion. Interference between the
battery connection wires and the actuator can cause damage to the wires and interruption of function.
»
do not use power supplies other than those provided with the device.
»
ensure that the Flex-Foot sock, shoe or any external load does not interfere with the actuator motion, since this can
cause restriction of the ankle motion.
• Lithium-ion batteries contain hazardous metals and should never be disposed of in residential or commercial
garbage. They should never be incinerated because they may explode.
• Perform field servicing at the recommended intervals, according to the instructions (see chapter “Service” ). This
will prevent malfunction or failure. Not following the instructions invalidates the warranty.
•
avoid
spillage or immersion in water (or any other fluids), use in highly electrical and/or magnetic
(i.e. electrical transformers, high-power radio/TV transmitters) and dirty environments.
• avoid exposure to extreme heat and/or cold (see “Technical specifications” ).
• avoid exposure to intense dust, smoke or mechanical vibrations.
•
do not
use if the product enclosure or covers are broken.
• do not tamper with the keypad.
• Disable proprio foot ® when driving a vehicle (see “Power off” ).
• Steep inclines or declines (above 20°) may trigger the stair response resulting in unexpected foot alignment.
• proprio foot
®
detects walking on uneven or level ground, walking on inclines and declines, climbing stairs and
riding a bike. Non-identified movements may cause unexpected ankle alignments.
• Not suitable for use in the presence of flammable anesthetic mixture with air oxygen or nitrous oxide.
• Protect the foot and battery pack against water or rain, and ensure that no water enters the battery charge plug.
• Battery performance may be affected by very low or very high temperatures that may cause inconsistency in
battery warnings.
