microAIR® MA50 Series 5.1.1 Power Button 1. To turn the control unit on or off, press and release the Power button A. Once the unit is plugged in, an Amber LED on the control unit is lit indicating that the system is in stand by mode. Once the Power button is pressed and released, a green LED illuminates indicating that the control unit is on. If the power comes on after a power outage, the control unit will go through its system initialization routine for a few seconds and then resume the desired function. 5.1.2 Static/Alternating Pressure Button 1. Press the Alternating Pressure button B to select between Static Mode and one of four Alternating Pressure Times-5, 10, 15, and 20 minutes. The alternating pressure times indicate the frequency of deflation or inflation of half of the air cushions (even or odd numbered). For example, 10 minutes is selected. In this example, the even numbered air cushions in the mattress will deflate, while the odd numbered cushions remain at constant pressure. When 10 minutes has elapsed, the even numbered air cushions will inflate while the odd numbered cushions remain at constant pressure. When 10 minutes has elapsed again, the odd numbered air cushions deflate while the even numbered cushions remain at constant pressure. The air cushions continue to inflate or deflate like this as long as an alternating pressure time has been selected. At all times, half of the air cushions remain at a constant pressure when an alternating pressure time has been selected. In Static Mode, all air cushions in the mattress are maintained at constant pressure. The Static LED is illuminated Green. 22 1148136-G
