5. CONFIGURATION
The configuration defines the mode in which we communicate with the module by means of DTMF tones
of a telephone call. Access to this configuration is gained by pressing the “CONFIG.” button on the
module and making a call through the telephone connection. Once the module answers, 10 digits must
be entered. Each digit configures a different parameter.
