Oscillation Zone
™
:
When the carriage reaches the Programmed Flexion
Angle, it will oscillate between the Programmed Flexion Angle and ten
degrees less than the flexion angle three times. The ten degree range
of motion is known as the
OSCILLATION ZONE ROM
. While in the
OSCILLATION ZONE ROM
, the carriage will move at 75 deg/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.
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 deg/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 one degree
every hour, up to a maximum of 5° per day.
How to Use:
While pressing and holding 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. The unit will not automatically increase
more than five degrees in any 24 hour period. Decreasing the flexion
angle will automatically deactivate this mode.
