Battery Installation

1. Refer to Figure 2, insert two AAA size batteries into the battery compartment properly, and note the polarity markings.
2. Replace the cover.
   Attentions:

• Make sure that the batteries are correctly installed. Incorrect installation may cause the device not to work.
• Remove batteries if the device is not being used for more than 7 days to prevent and avoid potential damage from the battery leaking. Any such damage is not covered under the product warranty.

Start/Stop Measuring

1. Open the clip and put a finger inside the clip (make sure the finger is in the correct position), and then release the clip. Wait for 2 seconds, the oximeter will power on and start to measure. If you connect the device to App, you can also check readings in App
2. Get the finger out, and the device will automatically power off.
3. Readings display screen The screen displays as below：
4. Recording & recall
   Recording & recall functions are available. At power-off status, pressing the Display key can bring up the record list display screen, as shown in figure 5. In record list screen, press the Display key to shift the records page.

If the time from displaying valid readings to the end of measurement is less than 5 seconds, then no recording will be done.
Up to 12 groups of records can be stored in the record list, the newest record is marked as M1, and the oldest record is marked as M12. The new record will override the previous record. If the batteries are removed from the device, then the records will be not kept or volatile.

Menu Setup

During measuring, long-pressing Display key can enter the setup menu screen.

Menu operating procedures:

1. Shortly press Display Key to choose the setting item;
2. Long press Display Key to active the setting item, then shortly press it to modify the setting parameter;
3. Long press Display Key to confirm the modification and exit from this setting item.
4. Move the setting item to “Exit”, and long-press Display Key to store the modification and exit from the setup menu.

“Beep”： Pulse beep option. If it is set to on, every pulse beat makes a beep. when the beep is on and the over-limits indication sound is activated, then the Display key will work as the ute key, and short time pressing it can mute the over-limits indication sound and pulse beep for 90 seconds.

Data transmission
The user could effectively transmit the data to App via Bluetooth.

Attention to the operation

• The finger should be put into the sensor correctly.
• Do not shake the finger and relax during measurement.
• Do not put wet finger directly into the sensor.
• Avoid placing the device on the same limb which is wrapped with a cuff for blood pressure measurement or during venous infusion.
• Do not let anything block the emitting light from the device, i.e. do not use fingernail polish/paints.
• Vigorous exercise and electrosurgical device interference may affect the measuring accuracy.
• Nail polish may affect the measuring accuracy, and too long fingernails may cause the failure of measurement or inaccurate results.
• The existence of high intensive light sources, such as fluorescence light, ruby lamb, infrared heater or strong sunshine, etc. may cause inaccuracy of measurement results. Please put an opaque cover on the sensor or change the measuring site if necessary.
• If the first reading appears with poor waveform (irregular or not smooth), then the reading is unlikely true, the more stable value is expected by waiting for a while, or a restart is needed when necessary

Frequently Asked Questions

1. Q: What’s SpO2?
   A: SpO2 means the saturation percentage of oxygen in the blood.
2. Q: What’s the normal range of SpO2 value for healthy people?
   A: The normal range varies by individual, but usually over 95%, otherwise, please consult your physician.
3. Q: What’s the normal range of PR value for healthy people?
   A: Usually, the normal range is 60bpm~100bpm.
4. Q: Why do the display value of SpO2 and PR vary with time?
   A: The measured SpO2 and PR value changes in correspondence with the change of patient’s physiological conditions.
5. Q: What to do if there is no SpO2 and PR reading?
   A: Do not shake the finger, and keep calm during the measurement Please also avoid the Oximeter and the cuff on the same limb for blood pressure and oxygen saturation measurement simultaneously.
6. Q: How to confirm that the SpO2 reading is true or accurate?
   A: Hold breath for a while (50 seconds or more), if the SpO2 value significantly decreases, it means that the SpO2 reading truly reflects the physiological condition change.
7. Q: When to replace the batteries?
   A: The icon of low battery will appear on the screen when the battery voltages are low. By then, batteries need to be replaced.
8. Q: What to do if the Oximeter is moistened or sprayed by water?
   A: Remove the batteries immediately and dry the Oximeter completely with a hair dryer.
9. Q: What factors will affect the SpO2 accuracy?
   A: Intravascular dyes such as indocyanine green or methylene blue;
   1. Exposure to excessive illumination, such as surgical lamps, bilirubin lamps, fluorescent lights, infrared heating lamps, or direct sunlight;
   2. Vascular dyes or external used color-up products such as nail enamel or color skincare;
   3. Excessive patient movement;
   4. Placement of a sensor on an extremity with a blood pressure cuff, arterial catheter, or intravascular line;
   5. Exposure to the chamber with High-pressure oxygen;
   6. There is an arterial occlusion proximal to the sensor;
