PROBLEM TO BE SOLVED: To provide a cordless phone system that accommodates many cordless phones each consisting of a master set connected to a host device via an extension and a slave set so as to suppress radio wave interference and reduce wireless connection errors. SOLUTION: Master sets 2, 4, 6 and slave sets 3, 5, 7 are wirelessly interconnected to configure cordless phones consisting of sets of the master set and the slave set (2+3), (4+5), and (6+7). The master sets 2, 4, 6 included in the cordless phones are connected to the host device 1 through extensions. The master set of each set, e.g. the master set 1 of the cordless phone (2+3) has a wireless module 23 connected to a communication circuit 21 leading to the host device 1, a CPU 22 and an antenna. The slave set 3 has a wireless module 31 connected to an antenna and a CPU 32. A wireless transmission output of each of the sets (2+3), (4+5), and (6+7) is automatically set to a plurality of stages in advance depending on conditions such as 'high output', 'medium output' and 'low output'. |
