Good Product
I've been using this product since I got covid in 2020. Simple and easy to use. Information on the website is very helpful.
1. Insert batteries 2. Check parameter settings 3. Insert finger fully into rubberised hold of the pulse oximeter with the nail surface facing upwards. 4. Release the clamp and press the power button to turn on the device. Device will turn off after 8 seconds if finger is not detected in the device.
Replace batteries timely when low voltage symbol shows. Clean the surface of the fingertip pulse oximeter before and after each use. Remove batteries when not in use for extended period of time. Store in a dry place, avoid damp/humid environment as it may affect its lifespan.
