PURPOSE:To improve the operability in the case of one slave set to be connected especially by storing in advance number of slave sets to be connected and controlling the calling based on the content stored at calling. CONSTITUTION:A master set 1 connects to a telephone line L, and plural slave sets 2-1, 2-2,...2-n connect to the master set 1 via a radio line. When number of slave sets to be connected is one, the slave sets 2-1 to 2-n are called by the operation of a call key only, while number of the connected slave sets 2-1 to 2-n is a plural number, designated slave sets are called by the operation of the call key and the operation of a key designating the slave sets 2-1 to 2-n. Thus, when number of the slave sets to be connected is one especially, the operability is improved. |
