Working of NCS-Esteem

             By turning ON the switch on the calling unit an indicator gets lighted up confirming that your call is passed on, which in turn reaches the Controller/Display unit and flashes the room number of the patient on it. simultaneously, the Voice module in it announces the call which forces the nurse to give immediate attention.
            After noticing the call the nurse can silence the voice module by pressing the MUTE button on Controller/Display Unit which makes the flashing window steady but it will continue glowing unless it is cleared by the nurse from the patient”s room using the calling unit. If another patient raises a call, again the same procedure takes place independent of the preceding call.
            Thus NCS ensures a positive and immediate response from the nurse for the patient needs.
