10. Transport Mode
11. Alarms & Fault Findings
The Heritage II Digital is equipped with audible and visual alarm indicators. These alert the user to the
status of the available mains supply and any mattress defect.
11.1 Low pressure alarm
Upon detection of low pressure, an audible alarm will be heard and the Low Pressure indicator will
illuminate. The audible alarm may be cancelled by pressing the Alarm Mute button. The Low
Pressure indicator will continuously illuminate until the low pressure fault condition is resolved.
This condition could be caused, for example, by incorrect fitting of the air pipe connector, opening of
the CPR valve or a leak in the mattress due to a cut or puncture.
11.2 Power failure alarm
If at any time the mains power should be removed from the power unit or the power cable is
unplugged without turning the power unit OFF, an audible alarm will be heard and the Power Failure
indicator will illuminate. The audible alarm may be cancelled by pressing the Alarm Mute button.
Note: When the power unit has not been used for more than 3 months, it might
require 60 minutes operating time (or more) for the Alarm to function correctly.
11.3 Service (alternating failure alarm)
Should your system develop a fault condition whilst in use, an audible alarm will be heard and the
Service indicator will illuminate. Please refer to Table 1 for error codes and call Ultimate Healthcare
or your local distributor.

If the patient is being moved on the mattress, or there is a
power cut, general pressure can be maintained in the system
for an adequate period of time whilst disconnected from the
mains.
Simply disconnect air pipe connector and place the connector
cover over it. The air pressures in the mattress will now
equalise, but maintain a degree of comfort. This will maintain
the cells in their present state for approximately 48 hours.
It is important to restore the Heritage II Digital dynamic
replacement mattress as quickly as possible by reconnecting
the supply tubes to the power unit.
