Start PO2 - Positioning the oximeter

1. Open the pulse oximeter clamp, then place the middle, ring or index finger of your hand into the opening of the device. The fingernail should be on the screen side (the same side as the light emitter).
   
2. Press the button once to turn on the oximeter.
3. Keep your hand still during the measurement.
4. After a few seconds, your pulse oxygen saturation (SpO2) and heart rate (BPM) values will appear on the oximeter display.
5. If the signal is too weak, switch fingers and try again.
6. Remove the oximeter from your finger. The oximeter will automatically turn off after 5 seconds.
