NOMENCLATURE
PENDANT FUNCTIONS AND USE
Oscillation Zone™: When the carriage reaches the
Programmed Flexion Angle, it will oscillate between the
Programmed Flexion Angle and 10° less than the flexion
angle, three times. The 10° range of motion is known
as the Oscillation Zone ROM. While in the Oscillation
Zone ROM, the carriage will move at 75°/min. or the
Programmed Speed, whichever is slower. On the third
oscillation cycle, the carriage will hold at the flexion
angle for the Programmed Extension/Flexion Delay
Time. See Chart 3.
How to Use: While pressing and holding the Mode
button, press the Oscillation Zone button to enable the
Oscillation Zone mode.
NOTE: If both Fast Back™ and Oscillation Zone modes
are enabled, the carriage will move at the slower of 75°/
min. and half of the Programmed Speed while in the
Oscillation Zone ROM.
Progressive ROM™: When Progressive ROM is
activated, the unit will automatically increase the
Programmed Flexion Angle by 1° every hour, up to a
maximum of 5° per 24 hour period. See Chart 4.
How to Use: Press and hold the Mode button. Press the
Progressive ROM button to enable the Progressive
ROM mode. Set the desired Final Flexion Angle by
pressing and holding the Flexion Button while using
the Up and Down Arrows. Accept the Final Flexion
Angle by pressing the Mode Button.
NOTE: The unit must run for a full hour at the entire
ROM before the flexion angle will be increased.
Decreasing the flexion angle will automatically
deactivate this mode.
