Considerations for Safe Operation of the System 4:
1. The clinician should always be present during testing or activity sessions. Do
not allow subjects to test or exercise by themselves.
2. Range limits should always be set after the subject is positioned according
to protocol and before switching to a test or activity mode. Limits should
never be set at points that are beyond the safe maximum allowable range of
motion for the individual subject.
Always assume that previously set limits are inappropriate for successive
subjects, or for successive joints on the same subject. Limits should be
canceled and reset at the completion of each test or activity session.
3. Range of motion limits should be set ensuring that the mechanical stop on
the attachment or fixture will not contact the mechanical stop on the
dynamometer. Metal-to-metal contact of these parts during operation will
override the system’s normal deceleration function (cushion), causing harsh
impacts at ends of ROM.
4. Always educate subject as to function and use of the Comfort Stop buttons.
Always place the hand-held remote Comfort Stop (on black coiled cord) in
the subject’s free hand before the start of any test or activity session.
5. During set-up, check subject positioning and ability to complete range of
motion (slowly) prior to securing stabilization straps. Ensure that both the
positioning chair and dynamometer are securely locked in detentes before
allowing subject to move through ROM.
6. Before beginning any test or activity session, always inform the subject that
the input attachment will now be able to move.
7. Always keep the surrounding area free of equipment and other personnel,
especially when the passive mode is to be used. Check for clear,
unobstructed path of movement pattern (through complete ROM).
8. Do not operate equipment that has malfunctioned until it has been serviced
by a qualified technician or use has been approved by a Service
Representative.
9. Use equipment only with recommended power supplies, grounding, and
surge suppression. (Refer to site survey or contact Service Department for
specifications.)
