1. Introduction
The CONTEC CMS50Q1 Fingertip Pulse Oximeter is a portable, non-invasive device designed for spot-checking of oxygen saturation (SpO2) and pulse rate (PR) through the finger. It is specifically designed for individuals with small fingers, such as children, and is suitable for sports and aviation use. This device is not intended for medical diagnosis or treatment.
Important Note: This device is for Sports or Aviation use only and is not a medical device. Consult a healthcare professional for any medical concerns.
2. Product Overview
2.1 Key Features

This image demonstrates the battery installation process and subsequent steps for taking a measurement.
3.2 Attaching the Lanyard
Thread the thin loop of the lanyard through the lanyard loop hole on the oximeter. Then, pass the larger part of the lanyard through the thin loop and pull gently to secure it. This allows for convenient carrying.
This image shows the device dimensions and how to attach the included lanyard.
4. Operating Instructions
4.1 Taking a Measurement
- Ensure the oximeter has batteries installed.
- Open the clip of the oximeter.
- Insert one of your fingers (preferably the index finger) into the rubber opening of the oximeter, ensuring the finger is placed correctly and fully inside. The device is designed for finger diameters greater than 0.2 inch (5mm).
- Press the power button once to turn on the oximeter.
- Keep your hand still and avoid movement during the measurement.
- The SpO2 and pulse rate readings will appear on the display within a few seconds.
4.2 Display Orientation
The display of the CMS50Q1 Pulse Oximeter can rotate automatically to provide optimal viewing from different angles. Simply adjust the device's orientation, and the display will adapt.
This image demonstrates the rotatable display feature of the oximeter.
4.3 Automatic Power Off
The device will automatically power off after approximately 5 seconds of inactivity (when no finger is detected) to conserve battery life.
5. Display Information
The TFT display provides the following information:
- SpO2 (%): Blood Oxygen Saturation level.
- PRbpm: Pulse Rate in beats per minute.
- Bar Graph: A visual representation of pulse strength.
- Pulse Waveform: A graphical representation of the pulse.
- Low Battery Indicator: An icon indicating when batteries need replacement.
This image shows a typical display reading with SpO2, PRbpm, and the pulse waveform.
6. Maintenance and Care
6.1 Cleaning the Oximeter
- Clean the surface of the oximeter before and after each use with a soft cloth dampened with medical alcohol (70% ethanol or isopropanol).
- Do not immerse the device in water or other cleaning solutions.
- Ensure the device is completely dry before reuse.
6.2 Battery Replacement
When the low battery indicator appears on the display, replace the batteries promptly. Follow the battery installation steps in Section 3.1.
6.3 Storage
Store the oximeter in a cool, dry place away from direct sunlight, extreme temperatures, and humidity. If the device will not be used for an extended period, remove the batteries to prevent leakage.
7. Troubleshooting
| Problem | Possible Cause | Solution |
|---|---|---|
| No display after power on | Batteries are dead or incorrectly installed. | Replace batteries or reinstall them with correct polarity. |
| Display shows '---' or unstable readings | Finger not inserted properly; excessive movement; cold finger; nail polish. | Reinsert finger correctly; remain still; warm the finger; remove nail polish. |
| Device turns off automatically | Normal auto-off function (5 seconds inactivity) or low battery. | This is normal behavior. If unexpected, check battery level. |
| Difficulty opening battery cover | Screw is too tight or cover is stiff. | Use the provided screwdriver. Apply gentle, even pressure to slide the cover after unscrewing. |
