1. An electronic system comprising:
- a user interface configured to transmit an operational parameter control signal in response to manual manipulation of the user interface, the user interface including a plurality of pushbuttons, the user interface being configured;
to be disabled by depressing the pushbuttons in a first predetermined sequence; and
to be enabled, when in the disabled state, by depressing the pushbuttons in a second predetermined sequence, the second predetermined sequence being different than the first predetermined sequence;
a processor coupled to the user interface and configured to adjust an operational parameter of the electronic system in response to receiving the operational parameter control signal; and
an actuatable device configured to;
be actuated by a user; and
in response to the user actuation, prevent the processor from adjusting the operational parameter of the electronic system.

Abstract
An electronic system including a user interface for transmitting an operational parameter control signal in response to manual manipulation of the user interface. A processor is coupled to the user interface and adjusts an operational parameter of the electronic system in response to receiving the operational parameter control signal. An actuatable device is actuated by a user. In response to the user actuation, the actuatable device prevents the processor from adjusting the operational parameter of the electronic system.

8. An electronic system comprising:
-
an electronic apparatus including; a user interface configured to transmit an operational parameter control signal in response to manual manipulation of the user interface, the user interface including a plurality of pushbuttons, the user interface being configured to be; disabled by depressing the pushbuttons of the user interface in a predetermined sequence; and enabled, when in the disabled state, by depressing the pushbuttons in the predetermined sequence; a processor coupled to the user interface and configured to adjust an operational parameter of the electronic apparatus in response to receiving the operational parameter control signal; and a remote controller including a user-actuatable pushbutton, the remote controller being configured to; in response to a first actuation of the pushbutton, transmit a first air-borne signal to the electronic apparatus to inhibit the processor from adjusting the operational parameter of the electronic apparatus; and in response to a second actuation of the pushbutton after the first actuation, transmit a second air-borne signal to the electronic apparatus to enable the processor to adjust the operational parameter of the electronic apparatus in response to receiving the operational parameter control signal. - View Dependent Claims (9, 10, 11)

12. An electronic system comprising:
-
a body; a user interface disposed on the body, the user interface being configured to transmit a control signal in response to manual manipulation of the user interface; a processor coupled to the user interface and configured to adjust an operational parameter of the electronic system in response to receiving the control signal; a switch disposed on the body, the switch having a lock position and an unlock position; and a remote controller including a user-actuatable pushbutton; the electronic system being user-configurable to enable a user to switch between; a first configuration in which when the switch is in the lock position, the user interface remains disabled regardless of the pushbutton of the remote controller being depressed, and when the switch is in the unlock position, the user interface toggles between enabled and disabled states in response to the pushbutton of the remote controller being depressed; and a second configuration in which when the switch is in the unlock position, the user interface remains enabled regardless of the pushbutton of the remote controller being depressed, and when the switch is in the lock position, the user interface toggles between enabled and disabled states in response to the pushbutton of the remote controller being depressed. - View Dependent Claims (13, 14, 15, 16, 17, 18, 19, 20)
