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.
