Claims

[Scope of utility model registration request]

For devices with a dedicated control circuit that includes a key power detection unit and a memory for writing dial data, the dedicated control circuit is equipped with a call return switch, which is turned off during a call, and the dial number is stored in the memory using the key power. and when the call ends, the callback switch is turned on and the call is made manually using the keys stored in the memory.
