▶Do not allow the electrodes of the device to come into contact with
other conductive parts (including earth).
▶ Do not store the device in the following locations: locations in which
the device is exposed to direct sunlight, high temperatures or levels of
moisture, or heavy contamination; locations near to sources of water or
fire; or locations that are subject to strong electromagnetic influences.
▶ Vital signs measurements, such as those taken with this device,
cannot identify all diseases. Regardless of the measurement taken
using this device, you should consult your doctor immediately if you
experience symptoms that could indicate acute disease.
▶ Do not self-diagnose or self-medicate on the basis of 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 device has no alarms and will not sound if the measurement
reading is too low or too high.
▶ 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.
▶Do not use the Oximeter on the same hand/arm when using a blood
pressure cuff or monitor.

Daily Check measurement is a function that combines the measuring
of ECG (Electrocardiograph), SpO2 (blood oxygenation) and systolic
blood pressure. It takes only 20 seconds to collect your vital signs
before giving you vital signs readings and your health evaluation.
Using Daily Check
To start a Daily Check, follow the steps as below.
1. If you have not created user, then please follow the instruction in
[Settings Section] to add your user account.
2. Tap the <Daily Check> icon in the middle of the screen.
3. Choose the right user.
4. Hold the device according to the instruction, keep the device at the
same level as your heart, and keep stable posture and stay calm. Don’t
exert too much pressure on the ECG electrode, which may result in
EMG (electromyograph) interference. Just hold gently and ensure
good contact with the ECG electrode. Do not exert pressure on the
finger that put in the SpO2 sensor. Just fit it inside but gently to
ensure good blood perfusion.

nail to squeeze the edge of the SpO2 sensor
cover, then move in upward to the left
to raise it up as shown below.
(2) Press the right thumb on the right
electrode.
(3) Press the right middle finger on the back
electrode.
(4) Press the left electrode to the left palm.

MEASUREMENT
PROCEDURE

Daily Check provides the trending graph of heart rate, SpO2 and blood
pressure. To view the trend, tap the button, then select one record, and
then tap the button.
BP Calibration
Warnings and Cautionary Advices
▶For a given user, it is suggested to make BP calibration every three
months.
To get blood pressure readings, this device should be calibrated by a
doctor with a traditional cuff blood pressure (BP) meter. Because of
individual differences, each user must make his/her own calibration
before using Daily Check to measure or track the blood pressure. The
calibration should be performed when the user is under calm status.
To calibrate with a cuff BP meter, follow the steps as below.
1. Select the <Settings> icon, select <BP Calibration>, and then choose
the right user.
2. Ensure that the cuff and the Vital Signs Monitor are at the same level as
your heart. Then start the blood pressure measurement from the cuff BP
meter.
3. Press the button on thescreen, and start the DailyCheck
measurement.
4. When the blood pressure measurement is finished, manually input the
readings of systolic pressure.
5. Repeat the calibration once again by following the above steps.
ECG Recorder
About ECG Recorder
The ECG recorder offers four different methods to measuring ECG. Tap the
f icon to switch between two pages.
As shown above, from left to right, there are:
▶ Method A: Lead I, right hand to left hand
▶ Method B: Lead II, right hand to left abdomen
▶ Method C: Lead I, left wrist to right wrist
▶ Method D: Lead II, right wrist to left lower abdomen
ST segment analysis is performed on selected LEAD.
MEASUREMENT
PROCEDURE

MEASUREMENT
PROCEDURE
Method A and B offer maximum comfort, than method C and D, but no ST
segment value. No matter which method you choose to measure ECG,
please keep stable posture and stay calm during the measurement.

Do not press the device too firmly against your skin, which may result in
EMG (electromyograph) interference. After you finish the above steps,
hold the device stably and stay calm.
3. Once the device detects stable waveform, it will automatically start the
measurement. The countdown bar moves from left to right.
4. When the bar if fully filled, the device will analysis your data, and then
show the measurement result.

MEASUREMENT
PROCEDURE
Measuring with Cable
To start an ECG Recorder measurement with cable,

2. Follow the instructions to connect the ECG cable and place the ECG
electrodes.
▶ Sit down or stand,/ stay calm;
▶ Palms facing up, place an electrode in the middle of right wrist;
▶ For method C, place another electrode in the middle of left wrist;
▶ For method D, place another electrode in the left lower abdomen;
3. The display will then show your ECG waveform.
The device will monitor your ECG continuously, however no data will be saved
until you press the button.
4. Press the button to start collecting your ECG data. The countdown bar
moves from left to right.
5. When the bar is fully filled, the device will analysis your data, and then
show the measurement result.

measurement very quickly by picking up the device and hold it according to
method A. This saves time and is much easier for use.
In the Settings menu and tap <Quick ECG> to enable or disable this function.

MEASUREMENT
PROCEDURE
Temperature
About thermometer
Warnings and Cautionary Advices
The thermometer is only designed for the measuring area on the
human body stated in this manual.
▶The device needs to be in the room which the measurement is taken
for at least 10 minutes before use.
▶Physical activity, increased perspiration on the forehead, taking
vasoconstictive medication and skin irritations can distort the result.
▶ The forehead (temples) must be free from perspiration and
cosmetics.
Influences on forehead temperature include but not limited to
A person’s individual metabolism;
▶Age; Forehead temperature is higher in babies and infants than in
adults. Greater temperature fluctuations occur faster and more often in
children. Normal forehead temperature decreases with age.
▶ Environmental temperature;
▶Time of day; Forehead temperature is lower in the morning and
increases throughout the day towards evening.
▶ Activities; Physical and, to the lesser extent, mental activities increases
forehead temperature.
Taking Temperature Measurement
To start a temperature measurement,
1. In the Main Screen, select <Thermometer>.
2. Put the thermometer sensor on your temple.
Put sensor on
temple, click button
then scan to
forehead until you
hear a beep
3. Press the Home button once, you will hear “Bi-Bi” beep, which
indicates the measurement starts. Then move the thermometer
around the temple for around 3 seconds until you hear a long “Bi” beep,
which indicates the measurement is finished.
4. Take down the device, and the screen shows the measurement
result.
In the Settings menu, tap the <Thermometer> area to change between
Celsius degree (°C) and Fahrenheit degree (°F).
