8
4.2 Operating Instruction
1. Press the POWER button on the display panel to start the system.
2. For faster inflation, the AUTOFIRM function can be activated. This mode will last for 20
minutes and then it will return to default setting automatically.
3. After the mattress is fully inflated, user can change the setting according to their
preference or recommended by physician.
4.3 CPR
When there is an emergency to perform CPR on the patient,
quickly pull the CPR valves to release air from mattress. The
CPR valves are located at the head-end, right-hand-side of
the mattress. The air hose on the pump unit can be
disconnected for even faster deflation.
4.4 Comfort Range Setup
Users can adjust the pressure of air mattress by adjusting the comfort range from level 1 to 6.
Please consult your physician for a suitable setting.
When the Low Pressure Indicator is off, it indicates the mattress has reached to its preset
softness. Patient can lie on the mattress.
NOTE: Check to see if the suitable comfort range (or pressure setting) is selected
by sliding one hand between the air cell and the patient to feel the patient buttock.
Users should be able to feel the minimal contact.
4.5 Pulsation Function
The mattress will inflate to the preset pressure level and deflate to the next lower pressure
level on a cycle of 2 times per minute. This means a 30 second period for one inflating and
deflating cycle.
For example, if the Pulsation function is activated and the preset comfort level is set at level
2, then the pressure setting will increase and decrease 2 times per minute between comfort
level 2 and 1.
4.6 Low Pressure and Alarm Function
When an abnormal low pressure occurs for a long time, the Low Pressure Indicator (flashing
yellow LED) will light up with audible alarm. Check if all the connections are securely made
and that they are correctly installed as per installation instructions.
9
NOTE: If the pressure level is consistently low, check for any leakage at air cells or
connecting tubes. If necessary, replace any damaged cells or tubes or contact local
qualified dealer for repair.
If the control unit is equipped without audible alarm feature, the Low Pressure Indicator will
flash until the low-pressure fault condition is solved. If the control unit is equipped with
audible alarm feature, the Low Pressure indicator will flash and the alarm will sound when
air pressure is below normal (preset pressure). To silence the alarm, simply press the alarm
mute button, and it will be silent for 3 minutes; however, the Low Pressure Indicator still
remains flashing. After 3 minutes, alarm buzzer will alert again if the pressure has not yet
returned to normal.
4.7 Power Failure Alarm
If the pump unit has a sudden power outage during normal use, the power indicator LED on
the control panel will flash " yellow" light, and alarm will sound. To silence the alarm, simply
press Power button on the control panel.
When power failure situation occurs, alarm will last until backup battery is low or it can be
turned off by manual operation.
Once power failure alarm situation is resolved, it is recommended to turn "OFF" the main
power switch located at the lateral side of the pump. If the main power switch is not turned
"OFF", once the main power comes back again, the pump will start again at "Standby" status.

8. Troubleshooting
Problem
Solution
• Check if the plug is connected to main power.
• Check if there is any blown fuse.
Power is not ON
• Check if the connection between air tube connector to
pump unit is tightly secured.
• Check if the CPR is sealed.
• Check if there are any leakage on air cells.
• Check if all tubing connections along mattress are secured.
Alarm is on
(audible & visual)
• Pressure setting might be inadequate for the patient,
adjust comfort range 1 to 2 levels higher and wait for a
few minutes.
Patient is bottoming out
• This may happen when the AUTOFIRM is activated for
too long. Release some air by disconnecting the air tube
connector and change to preferred setting.
Mattress becomes too firm and
pressure can’t be reduced.
• Check if all the snap buttons or straps of mattress are
all securely fastened.
• Check if the mattress is fixed to the bed frame by
elastic straps.
Air Mattress is loose
• Press handles on both sides of air tube connector
slightly before pushing the connector into the pump unit.
Air tube connector won’t fit
into the pump unit
• Make sure the connector is tightly secured by hearing
“click” while pushing it into pump unit.
Large airflow from air
bladders
• This is normal since this system has high airflow and
numerous air loss holes on all bladders.
If your questions can't be answered with above information, it might require a technician to
take care the problem. Please contact your local dealer directly.
