Abstract
In order to achieve check and adjustment of electronic apparatus such as a VTR from a remote location, a tone dialer in a service company converts commands and data into tone signals for checking and adjusting a VTR in a user's house, which tone signals are transmitted by a telephone over a telephone line and input to a telephone in the user's house. The tone signals received by the user's telephone are converted into the commands and data by a gateway and input to the VTR.
