1. Introduction and Overview
The Amemo Fingertip Pulse Oximeter A320E is a portable, non-invasive device designed for spot-checking blood oxygen saturation (SpO2) and pulse rate (PR) in adults and children over one year old. It features a large OLED digital display, plethysmograph, and perfusion index (PI) for enhanced measurement reliability. This device is suitable for sports and aviation use, such as by mountain climbers, skiers, and bikers, or individuals interested in monitoring their SpO2 and pulse rate.

Key Features:
- Accurate Measurement: Deviates less than 1% under lab conditions for SpO2 accuracy.
- Advanced Display: Large Dual-Color OLED screen for clear readings in various lighting conditions.
- Plethysmograph and Perfusion Index (PI): Helps confirm the reliability of SpO2 and Pulse Rate measurements.
- Alarm Function: Auditory alarm to alert users when SpO2 and Pulse Rate exceed set limits.
- Auto Shut-off: Automatically turns off after 6-8 seconds of inactivity to conserve battery.
- Durable Design: Constructed with high-quality ABS shell, acrylic panel, high-speed computing chips, and medical-grade silicone finger mold.

4. Operating Instructions
4.1 Taking a Measurement
- Ensure your finger is clean and free of nail polish or any foreign matter.
- If your hands are cold, rub them together for about 10 seconds to warm them up, as cold fingers can affect accuracy.
- Press the power button to turn on the oximeter.
- Open the clamp and insert one of your fingers (preferably the index or middle finger) into the rubber opening of the oximeter, ensuring your fingernail faces upwards.
- Release the clamp. It is recommended to remain still during measurement.
- After a few seconds, the SpO2, Pulse Rate, Plethysmograph, and Perfusion Index will be displayed on the screen.
- The device will automatically power off after 6-8 seconds of removing your finger.

4.2 Understanding Readings
- SpO2 (%): Blood Oxygen Saturation level.
- PR bpm: Pulse Rate in beats per minute.
- Plethysmograph: A waveform that indicates the consistency of the pulse. When the wave amplitude is consistent, the pulse oximeter is optimized, and readings can be taken reliably.
- Perfusion Index (PI%): Indicates the strength of the pulse signal. A PI value greater than 0.2% generally suggests accurate blood oxygen readings.

4.3 Alarm Settings
The oximeter features an alarm function to notify you when your SpO2 or Pulse Rate falls outside predefined limits. To adjust these settings:
- With the oximeter on, press and hold the 'M' (Setting) button for 2 seconds to enter the settings menu.
- In the menu, press the power button once to switch between menu items (e.g., SpO2 High/Low, PR High/Low, Sound Reminder, Beep, Brightness).
- To change a setting value, press and hold the power button for 2 seconds. Use the power button to adjust the value, then press and hold again to confirm.
- Navigate to 'Exit' and press the power button to save changes and return to the measurement screen.

5. Maintenance
Proper maintenance ensures the longevity and accuracy of your Amemo Fingertip Pulse Oximeter A320E.
- Cleaning: Regularly clean the surface of the oximeter with a soft cloth dampened with alcohol. Do not immerse the device in water or use abrasive cleaners.
- Storage: Store the device in its carrying case in a cool, dry place, away from direct sunlight, extreme temperatures, and humidity.
- Battery Replacement: Replace batteries when the low battery indicator appears on the display. If the device will not be used for an extended period, remove the batteries to prevent leakage.
6. Troubleshooting
If you encounter issues with your pulse oximeter, please refer to the following common solutions:
| Problem | Possible Cause | Solution |
|---|---|---|
| No display after power on | Batteries incorrectly installed or depleted. | Check battery orientation; replace with new AAA batteries. |
| Inaccurate readings | Finger not inserted properly, movement during measurement, cold fingers, nail polish, or poor circulation. | Reinsert finger correctly, remain still, warm hands, remove nail polish, or try a different finger. Ensure PI is above 0.2%. |
| "Finger Out" message | Finger not detected or improperly placed. | Ensure finger is fully inserted into the device with the nail facing up. |
If the problem persists after attempting these solutions, please contact customer support.
