1. Introducció
The CONTEC CMS50M Fingertip Pulse Oximeter is a portable, non-invasive device designed for spot-checking of arterial hemoglobin oxygen saturation (SpO2) and pulse rate (PR) through the finger. It is suitable for use in home environments and for sporting and aviation activities. This device is not intended for continuous monitoring or as a medical device for diagnosis or treatment.
It features a small volume, light weight, and is convenient for carrying. The device displays pulse rate value and a bar graph for easy reading.

- Allibera el clamp.
- Press the power button on the front panel once to turn on the oximeter.
- Keep your hand still during the measurement. Do not shake your finger.
- The SpO2 and Pulse Rate values will appear on the display within a few seconds.

4.2 Comprensió de la pantalla
The bright LED display shows the following information:
- SpO2 (%): Blood Oxygen Saturation Level.
- PRbpm: Pulse Rate (beats per minute).
- Gràfic de barres: Indicates pulse intensity.
- Indicador de bateria: Mostra la durada restant de la bateria.

4.3 Apagada automàtica
The device will automatically power off after approximately 5 seconds of inactivity or when the finger is removed from the sensor.
5. Manteniment
5.1 Neteja del dispositiu
To ensure longevity and hygiene, clean the oximeter regularly:
- Wipe the surface of the device with a soft cloth dampened with medical alcohol (75% ethanol) or isopropyl alcohol.
- Clean the inside of the finger clip with the same method.
- Allow the device to air dry completely before use.
- Do not immerse the device in water or any cleaning solution.
5.2 Substitució i emmagatzematge de la bateria
When the low battery indicator appears on the display, replace the batteries promptly. If the device will not be used for an extended period, remove the batteries to prevent leakage and damage.
Guardeu l'oxímetre en un lloc fresc i sec, allunyat de la llum solar directa i de temperatures extremes.
6. Solució De Problemes
| Problema | Causa possible | Solució |
