Any items must be returned in their original condition to qualify for a refund or replacement. Your sales will provide the tracking number once our warehouse sends your parts out. The supply voltage is obtained from the AC ring sig- nal and the circuit is designed so that noise on the line or variations of the ringing signal cannot affect correct operation of the device.


The two tone frequencies generated are switched by an internal oscillator in a fast sequence and made audible across an output amplifier in the loud- speaker, both tone frequencies and the switching frequency can be externally adjusted. LSA is a monolithic integrated circuit designed to replace the mechanical bell in telephone sets in connection with an electro-acoustical converter.
