2. Product Description
The Rhythm Turn system, operated blower unit, is a very unique innovation of a
specialized mattress replacement. The system is primarily designed for at risk patients
or step-down intensive care units. It features continuous lateral rotation therapy in two
different degree (20 degree and 40 degree), which gently turns the patient from side to
side to significantly lower the risk of infection, pneumonia and other pulmonary
complications – illnesses that significantly ad to patient care costs and length of stay.

The Master Control Unit is user friendly designed and most of the functions are
self explained.
Rotation angle can be independently selected for 20 degree of 40 degree.
Rotation time can be adjusted in 5 min increments to 99 min. Or the caregiver
can even select the Static Function that will seize the Rotation Function and
provide only the True Low Air Loss Therapy.
Auto Firm Function provides a uniformly firmness for nursing procedure.
Power failures produce an audio alarm for added safety.
10 digital scales of Soft/Firm Comfort Control.
Double insulation to provide max silent operation.
Foot board mounting rack provides the convenience of placement.
Mattress Features
Individual air cushion design for maximum pressure distribution.
Each air cushion has orifices to provide true Low Air Loss therapy.
LAL Turning Mattress Replacement, eliminating the compromising effects of an
existing mattress.
Permanent inflated bed rails for added safety.

4. Instruction for Proper Use
1. Remove the existing mattress from the bed frame.
2. Replace the standard mattress with LAL Turning Mattress Replacement and make
sure orient mattress so that the air tube is placed at the foot of the bed.
3. Secure the straps beneath the mattress to the bed frame.
4. Hang the Master Control Unit on the foot-board of the bed frame. Attach the air
tubes connectors to socket on the left panel of the Master Control Unit. Be careful
on the color matching between the connectors and socket. (black connectors to
black socket, red connector to red socket)
5. Ensure the air hoses are not kinked under the mattress. (Could be verified by
simple visual check) For detail Air hose connection please refer Explode Diagram.
6. Zip the low shear top cover to the mattress. The top cover should be loosely fit to
the mattress.
7. Carefully plug power cord into a properly grounded power source. Turn on the
master mechanical power switch on the right side panel. The STANDBY LED
should illuminates.
8. Push the STANDBY/OPERATE button of the front panel. The OPERATE LED should
now be lighted up and the Master Control Unit should now start to spin.
9. Push the AUTO FIRM button for fast inflation. Allow 4 ~ 7 minutes for full inflation.
After the mattress is fully inflated, the caregiver can now transfer the patient on to
the mattress. Push the AUTO FIRM again to release the fast inflation mode. (Note:
The mattress can be inflated with patient lying on top).
10. Static Function: Push the static button and adjust the Contort Control by pressing
the SOFT/FIRM button to achieve the maximum patient comfort. On this mode the
system provides True Low Air Loss therapy. Perform a hand check by placing
hand under the patient buttocks between cells and foam. The patient should have
at least 4 cm of clearance between the buttocks and the bottom of the mattress.

11. Turning time can be adjusted by the CYCLE button. The time can be adjusted from
3 minutes to 95 minutes. (When Static Function is selected, the timing window
would not show any digits).
12. The Master Control Unit is equipped with power failure alarm. With this function
enabled, the Control unit generates a horn sound to signal to caregiver that main
power failure. The alarm can be disabled by pushing the Alarm Reset Button on
the front panel.
Caution: Immediate response by the operator is required with power
f ailure alarm.
13. LOCK-OUT: The Master Control Unit is also equipped with a manual locking-out
function. All function keys will be automatically disabled if the LOCK –OUT button
has not been activated. When lock-out has been engaged, the “LOCK OUT” button
will illuminate.
UNLOCKING
Unlocking the control panel is easy. Simply press the “LOCK OUT” button on the
control panel for 3-5 seconds or recycle the power by turning off and on the main
power switch.
14. 20 degrees turning function can be activated by pressing the “TURN” and select
desire turning therapy. “LEFT TURN” a l lo w s the mattress to turn to left and back
to horizontal. “RIGHT TURN” would have the same effect but turning to the right.
The “FULL TURN” al lo w s for full function of turning to left and right and s h o u ld
always activate with timer setting. The timer can be set by “CYCLE” button.

5
15. 40 degrees turning function can be activated by pressing the “BT” button and
follow the operation instruction on step 14.

The Master Control Unit
CAUTION
SWITCH OFF THE ELECTRICAL SUPPLY TO THE PUMP AND DISCONNECT THE
POWER CORD FROM THE MAIN SUPPLY BEFORE CLEANING AND INSPECTION
The master control unit should also be cleaned weekly using a damp soft cloth and m i ld
detergent.
The pump casing is manufactured from ABS plastic and if the case is soiled the pump
can be wiped down with a sodium hypochlorite solution to dilution of 1000ppm or any
EPA- approved hospital grade disinfectant. (Don’t use phenol base cleaning
solution).
The air filter should also be cleaned and checked as often as possible at a minimum of
every six months. Air Filter can be removed by pinching center of the filter and
pulling outward from the back of the Therapy control unit.
