TRANSMITTER RECOGNITION CODE REGISTRATION FUNCTIONMode Function Add mode Adds a newly received code while preserving any previously registered codes. The mode is used when adding a new transmitter. If the number of codes exceeds 4, the oldest registerd code is erased first. Rewrite mode Erases all previously registered codes and registers only newly input codes. Confirmation mode Confirms how many codes are currently registered. When adding a new code, this mode is used to check how many codes already exist. Prohibition mode Deletes all the registered codes and distables the wireless door lock function. This mode is used when the transmitter is lost. - OPERATION OF INTERLOCK FUNCTION
