The device also includes a first magnet mounted to the door, wherein magnetic force applied to the door exerts a moment on the door, and a second magnet mounted in the housing and positioned to hold the door shut by magnetic interaction with the first magnet. In addition, the device includes a user-movable mode-changing mechanism attached to a third magnet, and arranged to hold the third magnet out of proximity with the first and second magnets when the device is in a first mode, and to move the third magnet into proximity with the first and second magnets when the device is in a second mode so as to expel the first magnet away from the housing and open the door to expose items positioned behind the door. ## Claims ### Claim 1 An electronic medical device comprising: a device housing comprising a first magnet; a panel mounted to the device housing and comprising a second magnet wherein a magnetic attraction between the first magnet and the second magnet support the panel in a first panel position; and a device operation mode selection switch comprising a third magnet and having a first switch position corresponding to a first life-support mode of operation of the device, and a second switch position corresponding to a second life-support mode of operation of the device, wherein the device operation mode selection switch is configured to cause movement of the panel from the first panel position to a second panel position in response to a change in a position of the device operation mode selection switch from the first switch position to the second switch position, and wherein, when the device operation mode selection switch is in the first switch position, the device operates according to the first life-support mode of operation, and, when the device operation mode selection switch is in the second switch position, the device operates according to the second life-support mode of operation, and further wherein the change in the position of the device operation mode selection switch is configured to change a position of the third magnet and further wherein the first magnet repels the second magnet in response to the change in the position of the third magnet. ### Claim 2 (depends on 1) The device of claim 1, wherein one or more controls relevant to a second life-support mode of operation are located in an area of the device housing that is covered by the panel in the first life-support mode of operation. ### Claim 3 (depends on 1) The device of claim 1, wherein the panel is mounted to the device housing by a hinge along an edge of the panel. ### Claim 4 (depends on 1) The device of claim 1, further comprising an electronic display connected to a processor programmed to display a first set of instructions when the device is in the first life-support operation mode, and a different, second set of instructions when the device is in the second life-support operation mode. ### Claim 5 (depends on 1) The device of claim 1, wherein the device operation mode selection switch comprises a rotary switch wherein the third magnet is configured such that the change in the position of the device operation mode selection switch changes the position of the third magnet from a first orientation to a second orientation rotationally different than the first orientation. ### Claim 6 (depends on 5) The device of claim 5, wherein the rotary switch is arranged such that the change in the position of the third magnet causes the first magnet to rotate and repel the second magnet in response to the rotation. ### Claim 7 (depends on 1) The device of claim 1, wherein the panel is a pacer cover configured to conceal one or more pacer mode control knobs in the first panel position and configured to expose the one or more pacer mode control knobs in the second panel position. ### Claim 8 (depends on 7) The device of claim 7, wherein the one or more pacer mode control knobs comprise an electrode power output adjustment knob and a pacing rate selection knob. ### Claim 9 (depends on 1) The device of claim 1, further comprising one or more selection keys disposed in the device housing and configured to change parameters for controlling the device. ### Claim 10 (depends on 1) The device of claim 1 wherein the second life-support mode of operation is a pacer mode of operation. ### Claim 11 (depends on 1) The device of claim 1 comprising user-selectable areas, disposed on the device housing, for manual mode parameters, wherein the manual mode parameters comprise a defibrillator electrode energy, wherein the panel covers one or more pacing parameter adjustment knobs in a first panel position and does not cover the user-selectable areas for manual mode parameters in the first panel position. ### Claim 12 (depends on 11) The device of claim 11 further comprising a microprocessor and related circuitry configured to control the user-selectable areas such that the user-selectable areas are invisible to a user in an automated life-support mode of operation and visible to the user in a manual life-support mode of operation. ### Claim 13 A method of operating an electronic medical device having a first life-support mode of operation and a second life-support mode of operation, the method comprising changing a position of a device operation mode selection switch from a first switch position to a second switch position, wherein the first switch position corresponds to the first life-support mode of operation and further wherein the second switch position corresponds to the second life-support mode of operation, wherein the change in the position of the device operation mode selection switch causes a panel mounted to a device housing to move from a first panel position to a second panel position, wherein the device housing comprises a first magnet, the panel comprises a second magnet, and the device operation mode selection switch comprises a third magnet and further wherein a magnetic attraction between the first magnet and the second magnet supports the panel in the first panel position and changing the position of the device operation mode selection switch comprises changing a position of the third magnet such that, in response, the first magnet repels the second magnet. ### Claim 14 (depends on 13) The method of claim 13 wherein the second life-support mode of operation is a pacer mode of operation. ### Claim 15 (depends on 13) The method of claim 13 wherein the panel covers one or more pacing parameter adjustment knobs in the first panel position but does not cover user-selectable areas for manual mode parameters in the first panel position, the manual mode parameters comprising a defibrillator electrode energy.
