How do you turn on/off the Respironics SimplyGo?
Turn the device on by pressing the Power button twice. After the first press, the display screen and the button backlights turn on. Press the Power button a second time to place the device in operating mode. This second press helps prevent unwanted starts or inadvertent changes in oxygen flow. The introductory screen momentarily appears followed by the final operating mode screen. Turn off the device by pressing the power button twice.
