15-June-15Murata Electronics Oy 6/17www.murata.com Doc. nr. 82 2178 00 Rev.C4 SCA11H installation4.1 Positioning SCA11H into the bedPositioning of SCA11H is very important. 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 or3. On the side of the bedFigure 4. Position options for SCA11HIn addition the socket-outlet shall be installed near the equipment and shall be easily accessible.

15-June-15Murata Electronics Oy 8/17www.murata.com Doc. nr. 82 2178 00 Rev.C4.2 Setting SCA11H into configuration mode (Appendix 1)1. Ensure power is disconnected2. 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 power4. Wait about 5 s until the green power led starts to blink with 1s interval5. Attach SCA11H sensor node to the black attachment plate6. After steps 1-5 SCA11H is ready for positioning and configuration.Figure 6. SCA11H node without attachment plate4.3 Configuration (Appendix 1 and 2)1. Connect the used configuration device (for example laptop) to SCA11H's configuration network: muRata_CFG_XXXXXX using password: 24681012.Figure 7.

If the person in bed changes, calibration should be repeated in order to obtain reliable results for each person.

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.

15-June-15Murata Electronics Oy 14/17www.murata.com Doc. nr. 82 2178 00 Rev.C5 Testing the output of SCA11HWhen 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 UtilizationSCA11H 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.
