• Do not open the device cover without authorization.
  The cover should only be opened by qualified service personnel.
• The biocompatibility testing has been performed on the materials in contact with the person in accordance with 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 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.
• The local laws and regulations should be followed when disposing of the device and accessories.
• Do not maintain the device while it is charging.
• Please keep the cable away from children. It can cause strangulation.

Overview

Name: Pulse Oximeter
Model: PO6, PO6A
Model and Configuration see the table below.

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.

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

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

When this symbol displays on the device screen, it indicates the readings are unavailable right now.
It may be 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’s Bluetooth will be enabled automatically

after it’s turned on.
To establish a Bluetooth connection,

1. keep the device Bluetooth enabled.
2. Make sure the phone’s Bluetooth is enabled.

Notice:

• DO NOT PAIR in the settings of your phone.

Add a New Device
For the initial use, you need to add a new device.

1. Turn on the device, run phone, select <Oxyfit>;
2. Press the button on the side of the device

Smart Vibration by SpO2
When SpO2 drops below the preset value (threshold), the buzzer in the sensor will be activated. When SpO2 is restored, the sound will stop.

Smart Vibration by SpO2
When SpO2 drops below the preset value (threshold), the buzzer in the sensor will be activated. When SpO2 is restored, the sound will stop.

Smart Vibration by Pulse Rate
When your pulse frequency is higher than the upper limit or lower than the lower limit, the buzzer will be activated.

Maintenance

Time & Date
After connection with the phone, device time will upload from your phone time automatically.

Cleaning

The device can be repeatedly used. Please clean before reuse as follow:

• Clean the device with a soft, dry cloth with 70% alcohol and then let it air dry.
• Do not use petrol, thinners, or similar solvent.
• Clean the SpO2 sensor carefully with a cloth soaked in 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.
