Please note two main items:

1. Orientation of the SCA11H needs to be the same as printed on top of the node

(head to toes) 2. SCA11H measures the bed vibration caused by blood circulation and therefore it needs to be positioned in a place most optimal to measure this vibration. Figure 4 depicts possible positioning options for SCA11H. 1. Under the mattress pad. Do not place under a person but rather on the side or edge of the mattress. The recommended distance to the person to be measured is min 20 cm. 2. On the bed frame or 3. On the side of the bed Figure 4. Position options for SCA11H In addition the socket-outlet shall be installed near the equipment and shall be easily accessible. Murata Electronics Oy www.murata.com Doc. nr. 82 2178 00 6/17 Rev.C More examples for good positioning of SCA11H are shown in Figure 5. 15-June-15 Figure 5. Examples of good SCA11H attachment positions Murata Electronics Oy www.murata.com Doc. nr. 82 2178 00 7/17 Rev.C 15-June-15 4.2 Setting SCA11H into configuration mode (Appendix 1) 1. Ensure power is disconnected 2. Remove SCA11H from the attachment plate (attachment plate is the black plate attached with magnet to actual SCA11H sensor node, please see the figure below) 3. Plug in the power 4. Wait about 5 s until the green power led starts to blink with 1s interval 5. Attach SCA11H sensor node to the black attachment plate 6.

If the person in bed changes, calibration should be repeated in order to obtain reliable results for each person. Murata Electronics Oy www.murata.com Doc. nr. 82 2178 00 11/17 Rev.C Select Bed Sensor Settings tab 15-June-15 Figure 11. Calibration 1. Make sure that the SCA11H is positioned as instructed in chapter 4.2, bed is empty and it is not exposed to disturbances. 2. Start the empty bed calibration by clicking the Start button. This takes 1 minute. In case of disturbances the calibration can be started again. When succeeded, bed has been calibrated to the environment. 3. After empty bed calibration has been successfully performed SCA11H can be calibrated for the occupied bed. The monitored person should lie still on the bed and the occupied bed calibration can be started by clicking the Start button. This takes also 1 minute. Murata Electronics Oy www.murata.com Doc. nr. 82 2178 00 12/17 Rev.C 15-June-15 4.5 Completing configuration Select System Info tab Figure 12. System Info Check the configured settings are correct. If yes, click Reboot to complete configuration. SCA11H Bed Sensor Node has now been configured. Murata Electronics Oy www.murata.com Doc. nr. 82 2178 00 13/17 Rev.C 15-June-15 5 Testing the output of SCA11H When using SCA11H the first time with the specific bed it is recommended to ensure proper sensor position. Please use e.g. separately provided BCGDemoGUI to verify the measured raw data contains periodic signal due to pulse. If no periodic signal can be seen, sensor position should be improved. 6 Care Instructions and Safety Utilization SCA11H is maintenance free. AC-adapter must be disconnected from the power when cleaning the bed to avoid electric shock due to water or moisture. SCA11H does not need to be reconfigured or recalibrated in case of power out. 7 Declarations

- SCA11H operating temperature range is 10 to 55 C

- Non-authorized modification by user is prohibited.

- SCA11H sensor is not a medical device and has not been validated or approved as such. It should not be used to diagnose or treat medical conditions.
