Why does the PulseOx not turn on when I place my finger into it?
- First, make sure you are wearing the device correctly. Your palm should be face up, and the screen should be face up. Refer to the diagram below.
- Make sure your hand and fingers are warm.
- If all else fails, try replacing the batteries. The batteries typically last about 3-4 months. Insert two (2) AAA batteries.
- Important: it is not intuitive how the batteries are inserted into the device. Carefully match the polarity markings ( + and -). Refer to the diagram below.
