The user can repeat the recognition step 1309 each time that a new visible code 1120 is generated in step 1308. The communicating terminal 1200 reads the visible code information 1120 and displays at least some of the information to the user. The communicating terminal accesses data held by an application that it hosts or by a remote server, on a site accessible on the web. The user can continue to manually control the apparatus 100, or if the apparatus 100 comprises communication means 1005, the user can establish a connection between the communicating terminal 1200 and the communication means 1005, during a step 1310. The connection is a Bluetooth connection (registered trademark), NFC (acronym for "Near Field Communication" in English), Wi-fi (trademark) or by airwaves, for example. The connection can be initialized by means of a specific visible code 1120, for example. Once the connection is established, the communicating terminal 1200 can receive, during a step 1311, information from the control unit. The information can be device function parameters 100 that can be selected, operating parameters of the apparatus 100 whose values can be selected, access to an application hosted on the communicating terminal 1200, access to a page of a site on the web, to which the communicating terminal 1200 can access, a state of the apparatus 100 and / or an identification of the model of the apparatus 100. The step 5 of receiving information by the terminal 1311, can be realized in real time. Once the connection is established, the user interface 1100 of the apparatus 100 is reproduced, at equivalence, on the user interface 1205 of the communicating terminal 1200, during a step 1312. The user can control the connection. Apparatus 100 through terminal 1200 in step 1313. The actions that can be performed by the user through interface 1100 reproduced on communicating terminal 1200 are the same as those manually achievable during step 1307. If a failure occurs at one of the steps of the method 1300, the visible code generated in step 1308 may be representative of the failure to identify it by a code, for example. By recognizing the code visible in step 1309, the communicating terminal 1200 can first fill out a fault information sheet to be sent to an after-sales service, by means of an application or a page of a site on the site. canvas, for example. The user performing the recognition may be an employee of an after-sales service, for example.

The control steps 1307, generation 1308, recognition 1309, establishment 1310, reception 1311, reproduction 1312, and control 1313 can be performed in a different order. The steps of generation 1308, recognition 1309, establishment 1310, reception 1311, reproduction 1312, and control 1313 are optional.
