CMS50Q1 Pulse Oximeter

Instructions
The Pulse Oximeter can be used in measuring the pulse oxygen saturation and pulse rate through finger.The product is fit for family, hospital, oxygen bar, community healthcare, physical care in sports (It can be used before or after doing sports and it is not recommended to use the device during the process of having sport) and etc.

Major Features
1)SpO2 value display
2)Pulse rate value display, bar graph display
3)Pulse waveform display
4)The display mode can be changed
5)Screen brightness can be changed
6)Voice prompt for over-limit and low battery(optional)
7)PR sound indication(optional)
8)Low-voltage indication: low-voltage indicator appears before working abnormally which is due to low-voltage
9)Automatically power off function: when the device is under the state of measuring interface . it will automatically power off within 5 seconds if the finger falls out of probe
