STATE DATA INTERCEPTION SYSTEM FOR CORDLESS TELEPHONE SET

摘要

PURPOSE:To report the state of a working slave set in real time and in a short time through an unused set by providing a radio unit to a master set to form a radio link between the master set and the working slave set. CONSTITUTION:A radio link 500 is formed between a working set 200 and a master set 100. Then an unused set 300 intercepts the data signal on the using state of the set 200 which is transmitted to the set 200 from the set 100 via the link 500. The state of the set 200 is decided based on the intercepted data signal and this deciding result is displayed by an LED circuit 303 of the set 300.
