- Do not use the device in a combustible environment (i.e., oxygen-enriched environment).
- Never submerge the device in water or other liquids.
- Do not clean the device with acetone or other volatile solutions.
- Do not drop this device or subject it to strong impact.
- The device and accessories are provided non-sterile.
- Do not place this device in pressure vessels or gas sterilization devices.
- Do not dismantle the device, as this could cause damage or malfunctions or impede the operation of the device.
- Consult your doctor immediately if you experience symptoms that could indicate acute disease.
- Do not self-diagnose or self-medicate based on this device without consulting your doctor. In particular, do not start taking any new medication or change the type and/or dosage of any existing medication without prior approval.
- The biocompatibility testing has been performed on the materials in contact with the person by ISO10993.
- Do not place the SpO2 probe on a finger with edema or fragile tissue.
- Check the SpO2 sensor and cable before use. Do not use a damaged SpO2 sensor.
- Check the SpO2 sensor application site every 6-8 hours to determine the positioning of the sensor and the circulation and skin sensitivity of the patient. Patient sensitivity varies depending on medical status or skin condition. For patients with poor peripheral blood circulation or sensitive skin, inspect the sensor site more frequently.
- The functional tester cannot be used to assess the accuracy of the SpO2 sensor or a device.
- The device has no alarm system.
- Continuous use for a long time may cause allergies, redness, blistering, or burns. Check the wearing position every 6-8 hours.

Using the Device
Charging
Use the USB cable to charge the product. Connect the USB cable to a USB charger or the PC. There will be a battery logo flash on the device when charging. When the battery is low, the display screen will display a low-power prompt. A full charge will take 2-3 hours. After fully charged, the device will power off automatically. Note: The device cannot be used during charging, and if choosing a third-party charging adaptor (Class II), select one that complies with IEC60950 or IEC60601-1.
POWER ON/OFF
POWER ON:
Wear the device, it will turn on automatically.
POWER OFF:
The device turns off automatically in moment after you take off the sensor
Typical steps
- START. Charge the battery. Wear the device to power on.
- STOP. Take off the device, therecordingwillbe over after the countdown.
- DATA Uploading. Run your phone to download data.
Start working
- Wear the device on your index finger. Try to move the device along the forefinger to find the best fit. Avoid being loose. Loosewearing causes inaccurate measurements.
- The device will turn on automatically. After a few seconds, the device will begin to work.
Notice:
- If the working time is less than 2 minutes, the data will not be saved.
- Please avoid excessive motion.
- Please avoid strong ambient light conditions.
SpO2 measurement principle:
The Pulse Oximeter is a lightweight, portable health oximeter for use in the home or healthcare facilities. SpO2measurementtechnology is based on the developed photoelectron method, the circuit design and calculation software was developed by Shenzhen ViatomTechnologyCo., Ltd. The SpO2 sensor receives the optical signal from the red light and infrared light through the finger.
Insert the finger into the theoximeter, there are two emitting tubes (red light diodes and infrared diodes) located on the inner upside of the sensor and they can emit red light and infrared; There is the receiving end located on the inner downside of the sensor, and it can transmit the red light and infrared into the pulse signal through finger. The MCU receives the pulse signal, gets the frequency signal by counting, processes its digital signal, and finally gets the measured SpO2 value. The PR is averagely calculated by above peak intervals of the PR waveform.
Stop working & Upload the data
Take off the device, the countdown will begin. (If the working time is less than 2 minutes, there will be no countdown) During the countdown, if you wear the device again, the record will be resumed. After the countdown, the data will be ready for uploading. Notice: The built-in memory can store 1 record. The oldest will be overwritten by the 2nd. Please upload data to your phone in time.
How to Check Battery
Press the side button, you can switch the display between readings and battery.
Unavailable Symbol
When this symbol displays on the device screen, it indicates the readings are unavailable right now. It may caused by:
- Excessive movement;
- Poor signal, the finger is too cold;
Usually, the readings will recover in a few seconds when at rest.
Bluetooth Connection
The device Bluetooth will be enabled automatically after it’s turned on.
To establish a Bluetooth connection,
- keep the device Bluetooth enabled.
- Make sure the phone’s Bluetooth is enabled.
Maintenance
Time & Date
After connection with the phone, device time will be uploaded from your phone time automatically.
Cleaning
The device can be repeatedly used. Please clean before reuse as follows:
- Clean the device with a soft, dry cloth with 70% alcohol, and then let it air dry.
- Do not use petrol, thinners, or similar solvents.
- Clean the SpO2 sensor carefully with a cloth soaked with 70% alcohol and then let it air dry
Note:
The device is a non-sterile medical device and does not contain any sterile or degradable component thus the device is not subject to the shelf life requirements.
