PURPOSE:To improve operation by making it possible to send a channel number of not less than two digits through single operation, by storing a remote control transmitter with channel numbers of not less than two digits. CONSTITUTION:In remote-control transmitter 14, one of addresses of memory 8 is assigned via address assignment key 1, address counter 2 and address decoder 3 and memory switch 11 is closed after ten-digit and unit-digit digital switches 7a and 7b of channel number command circuit 7 are depressed, so that a channel number signal will be stored 8 at a previously-assigned address. For channel selection, operating a random key of keys 1 reads the channel number written at the assigned address in memory 8 and a code signal for two digits from read control circuit 6 is converted 9 in series and then sent out via transducer 10. In this way, a two-digit signal is automatically read out and sent out through the single operation of key 1. |
