correctly clicked into place, otherwise a leak may
occur. Attach the power lead, plug into the mains
outlet and switch the power on at the side of
power unit adjacent to the power lead entry. Once
inflated (approx. 5 minutes) increase the comfort
control setting to SEATED using the UP arrow
button.
NB. If using the power unit from an operating
mattress system, first press the MAX. INFLATE
button to fully inflate the mattress, then rotate
the air supply hose connector anti-clockwise and detach from the power unit to
seal the air within the mattress to leave it fully inflated. To reconnect the mattress
to the power unit after using the cushion, switch off the power unit and disconnect
the cushion adaptor. Re-connect the mattress air supply tubing to the power unit,
and switch on the power unit (operation will automatically default to Active mode).
b) To use the cushion whilst the mattress is operating, simply attach the air supply
hose from the cushion to the connection port on the side of the head end of the
mattress by matching up the alignment markings and pushing together the CPC
connectors until they
click into place
(Fig. 4), increasing the comfort control setting
to SEATED. The mattress and cushion will operate simultaneously, allowing the simple
transfer of the patient between the bed and chair. NB. When the patient is in bed,
return the comfort setting to the mattress settings of SOFT, MEDIUM or FIRM.
It should be noted that the use of an alternating air pressure cushion will increase the
patient’s seated height by approximately 5cm, and care should be taken to ensure the
patient’s comfort and security regarding height of foot and arm rests.
OPERATION BUTTONS
The operation buttons on the face of the power unit provide the following functions.
THERAPY MODE
Pressing the THERAPY MODE button will toggle between ACTIVE (1 in 4 alternating
air pressure cycle) and CONTINUOUS LOW PRESSURE therapy modes. The selected
therapy mode is shown on the display screen. The default mode is ACTIVE therapy. To switch
to CONTINUOUS LOW PRESSURE mode, press THERAPY MODE button for 2 seconds until an
audible tone is heard. The system will then display 'PLEASE WAIT' and requires approximately
2 minutes to initialise.
COMFORT CONTROL
Air pressure is regulated within each of the cells throughout the cycle so that support,
posture and therapy are constantly maintained at optimum levels, in response to
patient weight, movement and position. Equalisation of cell pressure automatically
takes place at each stage of the 1-in-4 cycle, again to ensure precise pressure
