The user interface may include a menu control for detecting at least one parameter from the user's operation of the controls to navigate the menu and applying this to subsequent operation of the user interface controls. The user parameter may be a direction of operation of the rotary control dial which the user associates with a particular direction of navigation within the menu. ## Claims ### Claim 1 An apparatus for treating sleep disordered breathing (SDB) in a patient, the apparatus comprising: a flow generator configured to deliver a supply of air at positive pressure in the range of 4 to 25 cmH2O; a display configured to display a plurality of screens to a user; a set of controls operable by the user; and a controller configured to control operation of the flow generator and the display, receive user input from the set of controls, detect whether at least one accessory device is connected to the apparatus, and determine the identity of the at least one accessory device, if the controller detects at least one accessory device connected to the apparatus; wherein the controller is configured to instruct the display to display a first screen of the plurality of screens based on whether the controller detects at least one accessory device connected to the apparatus and the identity of the at least one accessory device determined by the controller, if the controller detects at least one accessory device connected to the apparatus; wherein when the display is displaying the first screen and the controller receives user input from the set of controls, the controller is configured to instruct the display to display a second screen of the plurality of screens in response to the user input; and wherein when the display is displaying the second screen and the controller determines that a predetermined period of time has elapsed after the controller received user input without receiving further user input, the controller is configured to instruct the display to display the first screen. ### Claim 2 (depends on 1) The apparatus of claim 1, wherein the at least one accessory device is a humidifier and/or a heated tube. ### Claim 3 (depends on 1) The apparatus of claim 1, wherein the flow generator is operable in a plurality of modes including a standby mode, a mask fitting mode, a run mode, and an error mode. ### Claim 4 (depends on 3) The apparatus of claim 3, wherein when the flow generator is in the standby mode or the run mode, the first screen and the second screen each is a different one of a patient climate control screen, a humidifier level screen, a heated tube level screen, and a home screen. ### Claim 5 (depends on 3) The apparatus of claim 3, wherein when the flow generator is in the standby mode, the first screen is a patient home screen and the second screen is a patient setup menu screen. ### Claim 6 (depends on 3) The apparatus of claim 3, wherein when the flow generator is in the standby mode, the flow generator is configured not to deliver the supply of air at positive pressure. ### Claim 7 (depends on 3) The apparatus of claim 3, wherein when the flow generator is in the mask fitting mode, the flow generator is configured to deliver the supply of air at positive pressure to allow the user to check for leaks between a mask and the patient's face and, if necessary, adjust the mask. ### Claim 8 (depends on 3) The apparatus of claim 3, wherein when the flow generator is in the run mode, the flow generator is configured to deliver the supply of air at positive pressure to treat sleep disordered breathing. ### Claim 9 (depends on 3) The apparatus of claim 3, wherein when the flow generator is in the error mode, the controller has detected an error and the flow generator is configured not to deliver the supply of air at positive pressure. ### Claim 10 (depends on 1) The apparatus of claim 1, wherein the predetermined period of time is thirty seconds. ### Claim 11 (depends on 1) The apparatus of claim 1, wherein the set of controls are located on the flow generator. ### Claim 12 (depends on 1) The apparatus of claim 1, wherein the set of controls includes a dial to control ramp time, pressure, humidification, climate control level, and/or heated tube temperature and humidity. ### Claim 13 (depends on 1) The apparatus of claim 1, wherein if the controller does not detect at least one accessory device connected to the apparatus, the first screen of the plurality of screens is a flow generator default screen that is configured to enable adjustment, using the set of controls, of a flow generator operational parameter that is associated with operation of the flow generator, and wherein if the controller detects at least one accessory device connected to the apparatus, the first screen is a screen that is configured to enable adjustment, using the set of controls, of an accessory device operational parameter that is associated with operation of the at least one accessory device. ### Claim 14 (depends on 13) The apparatus of claim 13, wherein the flow generator operational parameter is a set treatment pressure or a ramp time. ### Claim 15 (depends on 13) The apparatus of claim 13, wherein the at least one accessory device is a humidifier and the accessory device operational parameter is a humidity parameter of the humidifier. ### Claim 16 (depends on 13) The apparatus of claim 13, wherein the at least one accessory device is a heated tube and the accessory device operational parameter is a heated tube temperature parameter. ### Claim 17 (depends on 13) The apparatus according of claim 13, wherein the at least one accessory device is a humidifier and a heated tube and the accessory device operational parameter is a climate control parameter. ### Claim 18 (depends on 13) The apparatus of claim 13, wherein the set of controls further comprises a first control and a second control, and wherein, when the display is displaying the first screen, the flow generator operational parameter or the accessory device operational parameter is adjustable in response to user interaction with the first control, and the display is configured to display the second screen in response to user interaction with the second control. ### Claim 19 (depends on 13) The apparatus of claim 13, further comprising a backlight configured to indicate different states of the flow generator.
