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.
