  • 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 the 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 to the PC.
There will be a battery logo flash on the device when charging. When the battery is low, the display screen will display low power promptly.

A full charge will need 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 a moment after you take off the sensor.

Typical steps

  1. START. Charge the battery. Wear the device to power on.
  2. STOP. Take off the device, the recording will be over after the countdown.
  3. DATA Uploading. Run your phone to download data.

Start working

viatom 4708 Pulse Oximeter - Start working

  1. Wear the device on the index finger. Try to move the device along the forefinger to find out the best fit. Avoid being loose. Loose wearing causes inaccurate measures.
  2. 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 the strong ambient light conditions.

SpO2 measurement principle:

The Pulse Oximeter is a lightweight, portable health oximeter for use in the home or in healthcare facilities. SpO2 measurement technology is based on the developed photoelectron method, the circuit design and calculation software was developed by Shenzhen Viatom Technology Co., Ltd. The SpO2 sensor receives the optical signal from the red light and infra-red light through the finger. Insert the finger into the oximeter, there is 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 the 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 the above peak intervals of the PR waveform.

Stop working & Upload 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
