Abstract
Upgradable functions which are to be a target of trial are previously stored as software (program) or hardware in a storage section of a system. When a user desires to try out the functions, the user gives an instruction to do so to the system via a display panel or the like. The system, upon receipt of the instruction (including the start, termination, extension of a period, etc., of a trial), provides the target functions as required, thus providing the trial of a functionally upgraded, new system to users more easily and flexibly than ever before.
