The audio visual signal activates if a fault is detected. To silence the audible signal the
‘mute’ button is pressed. When the system is muted the screen shows:
9.5.3.2. Mute
****MATTRESS DISCONNECT**** MUTE
Please make sure the connector is
securely fastened.
(note, fault shown is an example only)
Re-pressing the mute button reactivates the audible signal.
The mute setting will self-cancel after 30 minutes and the audible signal will re-sound.
Note: If the ‘power failure’ indicator activates the mute button will not silence
the audible signal. To silence, the system must be turned off by pressing the power
button.
When silencing the ‘power failure’ indicator the audible signal will not
reactivate after 30 minutes and all lights will extinguish – There will
be no indication that the system is powered down. Ensure power is
returned to the system as soon as possible to resume pressure relief.
Warning
When pressed a menu appears offering 4 different settings:
9.5.4. System Functions
9.5.4.1. Therapy Selection
1: Alternating
2: Constant Low Pressure
3: Pulsation
4: Max Inflate
Use the up/down cursor key followed by the selection key to initiate the chosen
setting.
1) Alternating: Operates an ‘AB’ cycle where alternate cells deflate and inflate over a
defined time period (see section 9.5.4.3) causing the pressure over any one part of
the body to change regularly, actively encouraging tissue perfusion.
2) Constant low pressure: Reduces the contact pressure by increasing the surface
area over which the patient is supported and by contouring to the shape of the
body, therefore redistributing pressure away from vulnerable areas. In this setting
the system runs in a static mode where the cells are not alternating and are within a
pressure range of 10 to 40mmHg (patient weight dependent).
When using the constant low pressure setting, to return to alternating it is necessary
to manually reselect alternating from the therapy menu, it will not automatically
default back.
