PENDANT FUNCTIONS AND USE
Start/Stop (Emergency Stop): Starts or stops the 
treatment.
How to Use: Press the Start/Stop (Emergency Stop) 
button to begin or end the treatment.
NOTE: When unit is stopped and the Start/Stop 
(Emergency Stop) button is pressed, the unit will 
immediately begin moving in the opposite direction of the 
last movement.
Comfort Zone™: Temporarily decreases the flexion 
ROM when discomfort is experienced during treatment.
How to Use: Press and the carriage will immediately 
reverse direction to move toward the extension angle. 
For the next five cycles, the carriage will operate in a 
range 5° less than the angle where the button was 
pressed. The Comfort Zone Flexion Angle is 5° less than 
the angle where the button was pressed. Once five 
cycles are complete, the Comfort Zone Flexion Angle 
will be increased by 1° each consecutive cycle until it 
reaches the currently Programmed Flexion Angle. See 
Chart 1.
NOTE: If Comfort Zone is pressed within 30° of the 
currently Programmed Extension Angle, treatment will 
stop and the message "Comfort Zone Too Small" will be 
displayed.
If pain is severe, do not use the Comfort Zone function. Stop 
treatment immediately. Failure to stop treatment could result in 
tissue damage and could compromise the surgical repair.
