Abstract
A programmable display device main body includes an address file detecting section for detecting whether a memory card stores a MAC address file, a password file detecting section for detecting whether the memory card stores a password file, and an activation control section for reading data from the memory card. The activation control section does not read data in a case where the memory card stores neither a MAC address file nor a password file.
