Electronic apparatus having improved diagnostic interface

An arrangement for providing remote support services to a user of an electronic apparatus, the apparatus comprising main operative functionality and a power provisioning system for powering the apparatus from an external power source, the power provisioning system comprising:

• a main power supply output for energising the main operative functionality of the apparatus when said power provisioning system is connected to said external power source, and
• a standby power source for energizing a subset of the components of the apparatus when said main power supply output is not energised, the apparatus further comprising a self contained subsystem including a memory for storing at least one parameter reflecting an internal state of the apparatus, said self contained subsystem being powered by said standby power source and including an encoder for encoding the parameters in an output signal and a transducer for generating a wireless transmission from the output signal, which transmission can be detected in the vicinity of the apparatus, so as to enable the parameter to be received and decoded,
• wherein the transmission is a sound including in-band encoded signals, the arrangement comprising;
• a telephone call handling system that provides at least one telephone number that the user can call to get advice from a human support agent;
• and
• a decoder within the call handling system for decoding sounds generated by the apparatus and transmitted within a telephone call made by the user so as to enable the apparatus to transmit the parameter to the call handling system for processing without requiring the user or any support agent to directly understand the parameter from the transmission,
• wherein the call handling system is arranged to generate a database query from the parameter for retrieving for presentation to a support agent diagnostic data for the apparatus.
