5. Understanding Your Readings

The display shows two primary measurements:

• SpO2 (%): Blood Oxygen Saturation level.
• PR (BPM): Pulse Rate (Heart Rate) in beats per minute.

The device is designed for sports and aviation use to monitor these parameters. It is not intended for medical diagnosis.

6. Maintenance and Care

• Cleaning: Wipe the finger chamber with a soft cloth dampened with alcohol before and after each use. Do not immerse the device in water or other cleaning solutions.
• Storage: Store the oximeter in a cool, dry place when not in use. Avoid extreme temperatures and direct sunlight.
• Battery Replacement: Replace batteries when the low battery indicator appears on the display.
• Long-Term Storage: Remove batteries if the device will not be used for an extended period to prevent battery leakage.

7. Troubleshooting

7.1 Additional Troubleshooting Tips

• Q: The values measured by different fingers of the same hand are different every time. A: Yes, the measured blood flow area is different every time. As long as the value is within the normal range, it is normal.
• Q: It takes a few seconds to read the data. A: It takes time to calculate.
• Q: The reading changes from low value to high value in a short time until it is stable. A: When the product receives infrared rays, the blood flow rate increases slowly until it is stable.
