Symptoms
Problems / Cause
Low Pressure
The mattress is set to a mode that
is too SOFT.
Change the mode button to standard (from Lo to High(+)
a firmer pressure setting) as required. If the mattress is still
too soft after a short period of 5 to 10 minutes, then please
call an engineer.
The CPR connector is not fully home. Check all tubing is not kinked within the mattress.
There may be a leak in the system.
Ensure that the tubing within the mattress is fully connected.
High Pressure
The mattress is excessively firm on a
constant basis.
Set mattress to a softer setting as clinically required.
Evaluate that the mattress to be of a “less firm” state after
a short period of 5 to 10 minutes.
If this is not achieved, then please follow the task as below
before calling an engineer for assistance.
Note: Check all tubing is not kinked within the mattress.

3. Troubleshooting
This symbol when illuminated (The blue indicator light) is not used to indicate that the
equipment is on or ready for use.
When a patient requires a true dynamic function or indeed more pressure in the cells,
as they may be uncomfortable or feel as though the support surface if too soft or unstable,
then please select a “Hi” setting (pressure 26mmHg). This must only be used by a trained
clinician as often too higher pressures can further agitate certain patients conditions.
When a patient requires less pressure in the cells, as they may be uncomfortable
or indeed hyper sensitive to cell movement or indeed if the patient is still reddening further,
then please select a “Lo” setting. This must only be used by a trained clinician.
This function is used to silence the Audible Warning. The LED will remain lit if the Audible
Warning has been silenced previously, however a fault is still detected. Refer to the power
switch (as above) in order to re-set fully. If the Audible Warning continues to sound repeatedly,
along with an illuminated light, then an engineer must be called.
This symbol indicates an “Audible Warning Failure”.
Please see trouble shooting guide below for how to re-set.
