SETTING CONFIRMATION SYSTEM FOR IDENTIFICATION CODE

PURPOSE:To provide the setting confirmation system for an identification code in which the identification code left not set is prevented. CONSTITUTION:A signal string sent from a transmitter 1 includes a call code CA, an identification code ID, and a check code CC. The check code CC represents the presence of setting of the identification code I in the transmitter 1. When the call code CA and the identification code ID are set to a receiver 2, the receiver 2 is set to the registration mode and the transmitter 1 sends a signal string. In the setting registration mode, the receiver 2 discriminates the presence of the identification code ID in the transmitter 2 by the check code CC. When the identification code ID is set, the call code CA and the identification code ID included in the signal string are registered and when the identification code ID is not set, it is noticed by a notice section 21.
