1. Set the On/Off switch on the side of the control unit to position 1 (On). 
2. Air will start to be pumped into the mattress and the diode over the chosen program will blink. Upon completion of the inflation process, the program mode diode will remain green constantly. Depending on its size, it takes approximately 20–30 minutes for the mattress to inflate fully. 
3. When the green diode for the chosen program mode is constant, the mattress system can be taken into use. 
4. It will take approximately 20-30 minutes for the system to adjust to the user.

NOTE: 

• Each time the system starts up, it will operate as follows: When using a mattress without an air safety mattress (CuroCell® OP10, CuroCell® CX10 and CuroCell® CX16), the control unit will completely inflate the main cells and then perform an automatic setting. When using a mattress with an air safety mattress (CuroCell® CX15 or CuroCell® CX20), the control unit always begins by completely inflating the safety mattress, followed by the other cells, and then perform an automatic setting. 
• Once automatic setting is complete, the control unit switches to a basic setting of Pulsating mode (when used for the first time) or to the previous setting. For more information see article on Control Unit Functions - CuroCell A4 - Instructions of Use. 
• During the automatic setting, try to avoid larger movements on the mattress, otherwise, the automatic setting time will be extended. 
• When using a mattress with a safety mattress in foam (CuroCell® CX16), the user can lie on the mattress even when not inflated. When using a mattress with an air safety mattress (CuroCell® CX15 or CuroCell® CX20), this must be inflated before the user can lie on the mattress. In both cases, the safety mattress will carry the load.
