SpO2
measurement
technology is based on 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
are two emitting tube (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 PR
waveform.

Stop working & Upload data
Take off the device, the countdown
will begin.
(If the working time is less than 2 minute, 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 4 records.
The oldest will be overwritten by the 5th. Please
upload data to your phone in time.
3.6
Screen Wake up
The screen will go off automatically for saving
power in Standard Mode; you can touch the key on
top to wake up the screen.
3.7
How to Check Battery
Touch the key on top, you can switch display
between readings and battery.
3.8
Unavailable Symbol
When this symbol displays on device screen, it
indicates the readings is unavailable right now.
It may caused by:
Excessive movement;
Poor signal, finger is too cold;
Usually, the readings will recover in a few seconds
when at rest.
3.9
Bluetooth Connection
The device 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 Bluetooth is enabled
.
Notice:
DO NOT PAIR
in the settings of your phone.
3.10 Add a New Device
For the initial use, you need to add a new device.
1)
Turn on device, run phone, select <O2Ring>;
2) Touch the key on top of device.
3.11 Smart Vibration by SpO
2
The vibrator in the sensor will be activated when
the SpO
2
fall below the pre-set value (Threshold).
The vibration will stop when the SpO
2
recover.
3.12 Smart Vibration by Pulse Rate
When your pulse rate is above the Upper
Threshold or below the Lower Threshold, vibration
will be activated.

Maintenance
4.1
Time & Date
After connection with phone, device time will
upload from your phone time automatically.
4.2
Cleaning
The device can be repeatedly used. Please clean
before reuse as follow:
• Clean the device with a soft, dry cloth with 70%
alcohol.
• Do not use petrol, thinners or similar solvent.
• Clean the cuff carefully with cloth soaked 70%
alcohol.
• The cuff must not be washed!
• Clean on the monitor and the arm cuff, and
then let it air dry.
