TRANSMITTER FOR SERVICE CALL SYSTEM |
摘要 |
PROBLEM TO BE SOLVED: To provide the transmitter for the service call system which enables the setting as to whether or not a notice tone is to be outputted depending on applications, without addition of a setting switch that leads to cost increase. SOLUTION: The transmitter 1 of the service call system, where a call signal is outputted for every operation of a call switch and displayed on a display section of a receiver receiving the call signal, transits to a notice tone mode when a power supply to a call switch 11 is applied without operating the call switch 11 or transits to a silence mode when the power supply to the call switch 11 is applied while operating the call switch 11. A notice tone is outputted for every operation of the call switch 11 in the notice tone mode, and no notice tone is outputted in the silence mode even when the call switch 11 is operated.
