1. Introducción
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.

4. Instrucciones de funcionamiento
4.1 Realización de una medición
- Abre la clamp del oxímetro.
- Insert one of your fingers (preferably the index or middle finger) into the rubber opening of the oximeter with the nail surface upward. Ensure the finger is fully inserted and rests on the sensor.
- Suelte 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 Comprender la pantalla
The bright LED display shows the following information:
- SpO2 (%): Blood Oxygen Saturation Level.
- PRbpm: Frecuencia del pulso (pulsaciones por minuto).
- Gráfico de barras: Indicates pulse intensity.
- Indicador de batería: Muestra la vida útil restante de la batería.

4.3 Apagado automático
The device will automatically power off after approximately 5 seconds of inactivity or when the finger is removed from the sensor.
5. Mantenimiento
5.1 Limpieza del dispositivo
To ensure longevity and hygiene, clean the oximeter regularly:
- Limpie la superficie del dispositivo con un paño suave.ampenriquecido con alcohol medicinal (etanol al 75%) o alcohol isopropílico.
- Clean the inside of the finger clip with the same method.
- Deje que el dispositivo se seque al aire completamente antes de usarlo.
- No sumerja el dispositivo en agua ni en ninguna solución de limpieza.
5.2 Reemplazo y almacenamiento de la batería
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.
Guarde el oxímetro en un lugar fresco y seco, alejado de la luz solar directa y de temperaturas extremas.
6. Solución de problemas
| Problema | Posible causa | Solución |
|---|---|---|
| Sin pantalla después del encendido | Las baterías están agotadas o instaladas incorrectamente. | Reemplace las baterías o vuelva a instalarlas con la polaridad correcta. |
| Display unstable or inaccurate readings | Finger not properly inserted; finger shaking; ambient light interference; cold fingers. | Re-insert finger correctly and keep still. Avoid strong light. Warm hands if cold. |
| Se muestra el mensaje "Dedo fuera" | Dedo no detectado o eliminado. | Ensure finger is fully inserted into the sensor. |
