The knee joint is weatherproof but not corrosion-resistant. Therefore, the knee joint should
►
not come into contact with salt water, chlorinated water or other solutions (such as soap or
shower gel, and body and/or wound fluids). Do not use the knee joint under extreme condi­
tions like diving or jumping into water. The knee joint is not designed for prolonged under­
water use or prolonged diving.
After contact with water, remove the Protective Cover (if installed) and hold the prosthesis
►
with the sole of the foot facing up until the water has drained from the knee joint and tube
adapter. Dry the knee joint and components with a lint-free cloth and allow the components
to fully air dry.
