Read more Frequently Asked Questions   Q: Unread automatically shut down. What could be the problem? Your finger does not reach the correct position (reach the light point and block this point), or the battery is low.   Q: Can the Pulse Oximeter be used on children? A: Yes. However, we highly recommend using a child pulse oximeter instead which is specifically made for children. The finger chamber of the Oximeter may be too big for the small fingers of children. This can affect the accuracy of the reading.   Q: How do I turn off the pulse oximeter? A: The pulse oximeter turns off automatically when no finger is inserted in the product for 8 seconds.   Read more
