Trouble shooting of Accutension Stethos and instructions

Post by Junfeng » Wed May 31, 2017 5:29 am

When you encounter sounds related problems, please read the trouble shooting related to sounds. If it does not solve your problem, please send a piece of record to us by tapping "Send" in Accutension Stetho app after you complete recording. You need to have your email setup in your iPhone/iPad to do this. Our email address is service@huludevices.com. By doing so, we will be able to help you. Most of sounds related problems are due to incorrect use.
  • Failed to register the product
Please watch this video to see if you followed the registration process. How "scan the QR code" works is shown in the video.



Here are some possibilities that you can not register.

a. The camera of your iPhone is disallowed to be used by Accutension Stetho

The App needs to use the camera to scan the QR code so you need to allow the use of the camera of your phone. Here is a video to show how you can turn it on in your iPhone Settings if you rejected when you were asked.



b. Your iPhone or iPad does not have internet access

The registration requires internet access to work. If the internet access is off, please turn it on.

c. Other reasons

Please try registration one more time. If it still does not work, please contact us.
  • Can't see visualization of pulse sounds but noise or just see weak signals in the sound curve but can hear when you playback with your earphone after recording
a. Please check if the stetho is plugged into the phone and the stethoscope is placed on the artery as shown in the instruction manual. If there is iPhone or iPad case, please remove the case and have try. The plug of the stethoscope can be stopped by the iPhone/iPad case. Please try not to use the converter/splitter.

b. Please make sure the diaphram side faces the skin of the arm. If all these are correct, have you started recording when the cuff is still inflated (the number on your blood pressure monitor still increases)? Here is a video to show how the visualization of the sounds (sounds curve) looks like if it records the noise during cuff inflation. In this case, the pulse signal might look like weak. Actually the pulse sounds are not affected. You can trim off the noise to improve sounds signal resolution as shown in the video.



c. If the above two donot work, please contact us through email and leave a post - we will figure it out for you.
  • When you do the calibration, there is no sounds signal displayed, even noise
When this happens, possibly the microphone of your iphone is disallowed to be used by Accutension Stetho when you were asked on the first run. So please turn it on in iPhone Settings. Please refer to the video on how to turn it on.
