PROBLEM TO BE SOLVED: To enable re-calling, when making a call to multiple portable terminals after receiving a call from a nurse call slave unit, even when there is a portable terminal to which the call cannot be made, in the middle of calling other portable terminals.SOLUTION: A control machine 4 includes: a call destination table storage section 41 for storing a call destination from each nurse call slave unit; and a setting time storage section 42 for storing a specific time to perform re-calling. The call destination table storage section 41 stores multiple portable terminals as call destinations with respect to each nurse call slave unit. A control machine CPU 43 continues calling of the portable terminals for a fixed time till the portable terminals respond after receiving a call operation, but when the specific time shorter than the call duration time elapses, the control machine CPU resets all calls, and then performs recalling. When there is a portable terminal to which the call cannot be made first, calling in the middle of the call duration time can be performed. |
