1) 

Open the battery compartment cover on the back of the device, shown as Figure 5. 

2) 

Install the two “AAA” Alkali batteries, pay attention to the polarity, shown as Figure 6.. 

3) 

Install the battery compartment, shown as Figure 7. 

 

Please make sure the batteries polarities are installed properly, to avoid any damage to the device. 

 

Please take out the batteries if the device is not used for a long time. 

 

Please replace the batteries in time when low-battery appears. 

 

Please replace two new batteries with same type at the same time. 

 

After replacing batteries, perform sync time with APP again. 

Disposal of scrap batteries should follow local regulations about environment. 
5.2 Data measurement 
1) 

Install the two “AAA” batteries properly, then the device will turn on automatically and enter to 
“Synchronous  Time...” interface. 

 

Figure 8 Synchronous time interface 

In “Synchronous    Time...” interface, Bluetooth will be turned on automatically. 
2) 

Three methods to exit from “Synchronous  Time...” interface. 

 

Before each measurement, make sure the device has been performed sync time, to insure accurate time for 
storing data. It indicates that the device needs to perform sync time when it displays “Synchronous  
Time...”, otherwise it will not store measurement results. 
The first method: 
Don’t perform sync time, press the button, then the device will enter to “Steps” interface from “Synchronous  
Time...” interface. 
The second method: 
Don’t perform sync time, wait for several minutes, then the device will enter to “Steps” interface from 
“Synchronous  Time...” interface. 
The third method: 
Perform sync time, connect to power, then the device will turn on automatically, when it enters to “Synchronous   
Time...” interface, connect it with App, then it will automatically adjust time. 
3) 

In “Steps” interface, insert the finger to the probe (fully insert), then the device will automatically enter to 
“SpO

2

” interface from “Steps” interface, shown as Figure 3. 

 

If the time is wrong, the device will not store data. 

 

Fingernails and the luminescent tube should be on the same side. 

 

During using, the testee’s finger should not shake, and keep quiet.   

4) 

Read SpO

2

 and pulse rate value directly from the screen after inserting the finger for about 4~8 s, shown as 

Figure 3. Pull out the finger after stable data appears to finish data storing. Only one result is stored from 
each inserting to pulling out the finger. 

5) 

In SpO

2

 state, screen direction can be changed automatically. 

6) 

The interface between “Steps” and “SpO

2

” interface can be switched by inserting the finger. 

a. 

In “Steps” interface, insert the finger to enter to “SpO

2

” interface. 

b. 

In “SpO

2

” interface, pull out the finger to enter to “Steps” interface, shown as Figure   

In “Steps” interface, Bluetooth will be in “ON” state all the time. 
7) 

In “Steps” interface for 1 minute, it will automatically enter standby mode. 

In standby mode, the screen does not display any contents, but the pedometer can work normally. 
In standby mode, Bluetooth is in “OFF” state. 
8) 

In standby mode, press Button to turn on screen display and enter to “Steps” interface shown as Figure 4. 

5.3 Data upload 
The device can transmit SpO

2

, pulse rate, Steps and calorie value to phone-side by wireless mode. 

User can add the device by searching it in PC-side, as each device has the unique code which is marked in the 
device enclosure, which provides convenience for user to upload the results to PC, avoids confusion caused by 
excessive and same devices. After measuring, the device will automatically connect to the PC communicated with 
it last time. 
In “STEPS” interface, Bluetooth is in “ON” state, and it is in “OFF” state in other interfaces. 

 

Before uploading steps data, please do sports for 5 minutes at least. 
The Pedometer can only upload the data(measured in the last day) on the next day.

6.1 Routine maintenance 
6.1.1 Cleaning and disinfecting 
Turn off the device before cleaning. Use medical ethanol to clean and disinfect the device, natural air-drying or 
clean it with a clean and dry cloth. Avoid any liquid entering to the device. 
6.1.2 Maintenance 
1) 

Keep the device away from dust, high temperature and humidity, and avoid strong shaking and hitting.
