The audio visual signal activates if a fault is detected. To silence the audible signal
the ‘mute’ button is pressed. When 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 20 minutes and the audible signal will re-sound.
When silencing the ‘power failure’ indicator the audible signal will not
reactivate after 20 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 3 different settings:
9.5.4 System Functions
9.5.4.1 Mode Selection
1: Alternating
2: Constant Low Pressure
3: Pulsation
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 9.5.4.5).
Weight(kg): 40■■■■■■□□□□□□□□□□□□□□267
Mode: Alternating
Pressure Setting: 13 mmHg
Cycle Time: 10 minutes
2) Constant low pressure: Patients should always be nursed on the mattress in
alternating mode but the CLP mode maybe selected for short intervals if a patient is
finding it difficult to tolerate the alternating mode. (This could occur if, for example,
the patient feels discomfort, nauseated or perhaps having difficulty getting to sleep).
When CLP is selected all cells inflate at the pressure to which the control unit is set,
thereby offering a non-moving surface.
