Different notifications exist based on how serious the warning is. With a malfunction or an error, a notification will be given by way of a flashing warning triangle. To mute the warning signal, press the mute button.
	When a notification occurs, the current cycle time diode will turn off and a notification code is shown on the four different cycle time diodes (10, 15, 20, 25). To read the cycle time during the error notification, unlock the control panel. For more information about the different notification codes, see Table of Notifications below.

Table of Notifications

Information about each notification is shown in the notification table: 

• Notifications from 1-10 are both audible and visual. The error code will be displayed until the error has been rectified. If the mute button is pressed the audible warning will crease for a period of 5 minutes and will return until the error has been rectified. 
• The notifications 11-13 have no audible alarm. The error code is shown until the system is restarted.

	Notification	Description and Troubleshooting
1		High temperature. Valves and compressors are turned off. If the control unit is in direct sunlight, relocate it. Otherwise, contact the support.
2		Default settings are not completed. Contact the support.
3		Incorrect input voltage. Make sure that the correct power supply is used, otherwise contact the support.
4		Low pressure. Secure the CPR, mattress, air tubes and air filter. If the problem remains, contact the support.
5		Automatic setting failure. The correct pressure has not been reached within the time limit. If the problem remains, contact the support.
6		Leakage under the automatic setting period. The mattress is leaking too much for the weighing to be accomplished. Control the mattress and the air connections. If the problem remains, contact the support.
7		High pressure. The pressure cannot be reduced to the desired value within the time limit. Contact the support.
8		The automatic setting has been restarted too many times during the automatic setting period. Contact the support.
9		The mattress control parameters have not been read. Connect the CPR or contact the support.
10		The mattress control parameters have been changed during the use. Restart the system. If the problem remains, contact the support.
11		Leakage in blue cell section. Secure the CPR, mattress and connection tubes. See section 4.2 for more information. If the problem remains, contact the support.
12		Leakage in green cell section. Secure the CPR, mattress and connection tubes. See section 4.2 for more information. If the problem remains, contact the support.
13		Leakage in red cell sections. Secure the CPR, mattress and connection tubes. See section 4.2 for more information. If the problem remains, contact the support.

Maximum Pressure Notification

When the function Maximum pressure has been used for a long time, the Maximum pressure diode will blink. If the use is intentional, ignore the notification.
