Abstract
A projector includes a communication unit configured to communicate with an external device, an operation unit configured to receive a user operation, and a system control unit. The system control unit is configured to validate a network function of the communication unit in response to receipt of a particular key sequence received by the operation unit in a stand-by state. The system control unit is configured not to validate the network function of the communication unit even if the operation unit receives the particular key sequence in an image projection state.
