1. Inngangur
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.

3. Uppsetning
3.1 Uppsetning rafhlöðu
- Locate the battery compartment on the back of the oximeter.
- Use the provided screwdriver to loosen the screw on the battery cover.
- Renndu rafhlöðulokinu af.
- Settu tvær AAA rafhlöður (ekki innifaldar) í hólfið og gætið þess að pólunin (+/-) snúi rétt.
- Replace the battery cover and secure it with the screw using the screwdriver. This screw helps prevent accidental battery access, especially for children.

This image demonstrates the battery installation process and subsequent steps for taking a measurement.
3.2 Festing á bandi
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. Notkunarleiðbeiningar
4.1 Að taka mælingu
- 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).
- Ýttu einu sinni á rofann til að kveikja á oximeternum.
- 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 Skjástilling
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 Sjálfvirk slökkt
The device will automatically power off after approximately 5 seconds of inactivity (when no finger is detected) to conserve battery life.
5. Birta upplýsingar
The TFT display provides the following information:
- SpO2 (%): Blood Oxygen Saturation level.
- PRbpm: Púlstíðni í slögum á mínútu.
- Súlurit: A visual representation of pulse strength.
- Púlsbylgjuform: A graphical representation of the pulse.
- Vísir fyrir lága rafhlöðu: An icon indicating when batteries need replacement.

This image shows a typical display reading with SpO2, PRbpm, and the pulse waveform.
6. Viðhald og umönnun
6.1 Cleaning the Oximeter
- Hreinsið yfirborð oximetersins fyrir og eftir hverja notkun með mjúkum klút.ampened with medical alcohol (70% ethanol or isopropanol).
- Ekki setja tækið í vatn eða aðrar hreinsilausnir.
- Ensure the device is completely dry before reuse.
6.2 Skipt um rafhlöðu
When the low battery indicator appears on the display, replace the batteries promptly. Follow the battery installation steps in Section 3.1.
6.3 Geymsla
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. Bilanagreining
| Vandamál | Möguleg orsök | Lausn |
|---|---|---|
| Engin skjár eftir að kveikt er á honum | Rafhlöður eru tómar eða rangt settar í. | 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. |
| Tækið slekkur sjálfkrafa á sér | 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. |
