4.1 Taking a Measurement

The oximeter features an efficient one-button operation for quick and easy measurements:

1. Open the clamp of the oximeter.
2. Insert one of your fingers (preferably the index, middle, or ring finger) fully into the rubber opening of the oximeter, ensuring your fingernail is facing upwards towards the display.
3. Release the clamp.
4. Press the power button once to turn on the device.
5. Keep your hand still. The device will automatically begin measuring. Your SpO2 (blood oxygen saturation) and PRbpm (pulse rate in beats per minute) readings will appear on the display within approximately 10 seconds. A pulse bar graph will also be displayed, indicating the strength of your pulse signal.

A visual guide demonstrating the quick and simple steps to take a measurement: open the oximeter, insert your finger, press the power button, and wait for the readings.

Ensure your finger is fully inserted into the device for accurate readings.

4.2 Understanding the Display

The OLED display offers 6 display modes, 4 display directions, and 10 levels of adjustable brightness for optimal viewing.

• SpO2: Blood Oxygen Saturation percentage.
• PRbpm: Pulse Rate in beats per minute.
• Pulse Bar Graph: Visual representation of pulse signal strength.
• Battery Indicator: Shows remaining battery life.

The oximeter's display can rotate in four directions for easy viewing from any angle.

4.3 Automatic Shut-Off

The device will automatically shut off after 8 seconds of inactivity to conserve battery life.

5. Maintenance and Care

5.1 Cleaning the Device

To clean the oximeter, wipe its surface with a soft cloth dampened with medical alcohol (75% ethanol) or isopropyl alcohol. Do not immerse the device in water or any cleaning solution. Ensure the device is dry before use.

5.2 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 and potential damage.

6. Troubleshooting

If you encounter issues with your oximeter, refer to the following common problems and solutions:

• No Reading or Inaccurate Reading:
  • Ensure your finger is fully inserted into the device.
  • Keep your hand still during measurement. Movement can affect accuracy.
  • Cold hands, poor circulation, or nail polish/acrylic nails can lead to inaccurate readings. Warm your hands if they are cold.
  • Verify battery levels. The battery indicator only appears when the battery is low. Replace batteries if needed.
• Device Not Turning On:
  • Check battery installation. Ensure batteries are inserted with correct polarity (+/-) and the battery compartment cover is securely closed.
  • Replace batteries with new ones if they are depleted.
• Pulse Rate Changing Rapidly:
  • Your heart rate naturally changes with emotions, excitement, and physical exercise. This is normal behavior.
