Using the CONTEC CMS50M Pulse Oximeter is straightforward. Begin by inserting two AAA batteries into the device, ensuring correct polarity. Next, secure the cover. Open the device's clip and place your finger into the rubber cushions. Make sure your finger is correctly positioned within the clip, and then close the clip firmly. Press the power button once to turn the device on. Remain still and relaxed during measurement. The device will then display your SpO2 (oxygen saturation) and pulse rate readings. This device is designed for adults weighing between 40kg and 110kg and is not suitable for infants or neonatal users. If you get unusual readings, reposition your finger and try again. Always consult the user manual included with your CONTEC CMS50M for detailed information and safety advice.
