Abstract: A device for management is attached to a copier, and the device for management is connected to a host computer at a management center via a telephone line. In a database of the host computer are provided a field for calculating an MCBJ since resetting or in a predetermined period, and a field for calculating a total MCBJ of copiers of a same model. Based on comparison between results obtained in these two fields, a warning is issued. Moreover, an MCBJ of a copier in a predetermined period is retained in the database for three consecutive such periods, so that a trend of the MCBJ of the copier is traced. A rising tendency of the MCBJ is judged from a combination of two trend-indicating values, one comparing an MCBJ two periods before with a current MCBJ and the other comparing the MCBJ two periods before with an MCBJ one period before. If the rising tendency exceeds a predetermined factor, a warning is issued.

Abstract: In order to prevent illegal use of a mobile telephone, a call is repeatedly originated from a telephone or base station to the mobile telephone over a wireless path. When the call is received by the mobile telephone over the wireless path so that a communication channel is established, a destruction code including a cryptographic data is transmitted from the telephone or base station to said mobile telephone. The mobile telephone receives the destruction code and compares the cryptographic data of the received destruction code with a preset data stored in the mobile telephone to determine whether both the data are matched. When it is determined that both the data are matched, the mobile telephone destroys a telephone functioning information stored in the mobile telephone and necessary for performing communication.
