Setting Date and Time

It is important to set the clock before using your blood pressure monitor, so that a time stamp can be assigned to each record that is stored in the memory.
(year: 2022—2050 Time format: 12H/24H)

Auto Setting
Once connected to smartphone App via Bluetooth, date and time will be syned to BPM automatically.

Manual Setting

1. When the monitor is off, press and hold the “START/ STOP ” button to display the date format. Press the “Bluetooth” or “Record” button to switch the date format  between [month/day] and [day/month].
2. Press the “START/ STOP ” button to confirm the date format, then the year will flash. Press the “Bluetooth” or “Record” button to change the year.
3. When you get the right year, press the “START / STOP” button  to confirm the year. The screen will then show a blinkingnumber representing the [MONTH].
4. Repeat steps 2 and 3 to set the [MONTH] and [DAY].
5. Repeat steps 2 and 3 to set the time format.
6. Repeat steps 2 and 3 to set the [HOUR] and [MINUTE].
7. After the minute is set, the LCD will display “do NE” and then it will turn off.

Tie The Cuff

1. Insert the air plug into the air jack
2. Wrap the arm cuff firmly in place around your left upper arm.

NOTES
The bottom edge of the arm cuff, should be 0.5 inch (1 to 2 cm) above the elbow. Air tube is on the inside of your arm and aligned with your middle finger.
3. Secure closed with the fabric fastener.

NOTES

• When you take a measurement on the right arm, the air tube will be at the side of your elbow. Be careful not to rest your arm on the air tube.
• The blood pressure can differ between the right arm and the left arm, and the measured blood pressure values can be different. We recommends to always use the same  arm for measurement. If the values between both arms differ substantially, please check with your physician which arm to use for your measurements.

Sit Correctly

To take a measurement, you need to be relaxed and comfortably seated, under comfortable room temperature.
Avoid bathing, drinking alcohol or caffeine, smoking, exercising or eating 30 minutes before taking a measurement.

• Sit in a chair with your legs uncrossed and feet flat on the floor.
• Sit with your back and arm supported.
• The arm cuff should be placed on your arm at the same level as your heart, with the arm resting comfortably on a table.

Start The Measurement

Notes:
-To stop the measurement, press the START/STOP button once to defalte the arm cuff.
-Remain still and quiet while taking a measurement.
Press the START/STOP button.
-The arm cuff will start to inflate automatically.
-The whole measurement takes around 35 seconds.

Measurement Tips

To help ensure an accurate reading, follow these directions:

• Stress raises blood pressure. Avoid taking measurements during stressful times.
• Measurements should be taken in a quiet place.
• It is important to take measurements at the same times each day. Taking measurements in the morning and in the evening is recommended.
• Remember to have a record of your blood pressure and pulse readings for your physician. A single measurement does not provide an accurate indication of your true blood pressure. You need to take and record several readings over a period of time.

CAUTION

• Avoid bathing, drinking alcohol or caffeine, smoking, exercising and eating for at least 30 minutes before taking a measurement.
• Rest for at least 5 minutes before taking  a measurement.

2. Each time you complete a measurement, data will be synced to App automatically, will blink during uploading and turn solid on after uploading successful.
3. If you data is not synced to App, will show in data page, indicating the record is not uploaded to App.
4. You could press ‘Bluetooth’ button when the blood pressure monitor is off to sync data that are not uploaded.

Delete the records

If you did not get the correct measurement, you can delete results by following steps below.

A: To delete a single measurement:

1. Enter the memory recall mode as described in section [Recall the Records]. Press “Record” or “Bluetooth” button to get the measurement you would like to erase.
2. Press and hold “Record” button for 3 seconds, and the display will show a blinking “dell yes” along with the memory number of the reading.
3. Use the “Record” or “Bluetooth” button to toggle between “dell yes” and “deli no”, Press “START/STOP” to confirm the selection.
   If “dell yews” is selected, the unit will delete the record and display “dell do NE” along with the memory number of the reading. After then it will return to last memory record and All the records are pushed forward one digit (e.g., 03 becomes 02, and so on)
   If “dell no” is selected, it will stop the deletion.

B: To delete all measurements:

1. Enter the memory recall mode as described in section [Recall the Records].
2. Press and hold “BLUETOOTH” and “RECORD” button for 5 seconds, and the display will show a blinking “dEL ALL” along with the user ID.
3. Use the “BLUETOOTH” or “RECORD” button to toggle between “dell ALL” and “dell no”, Press “START/STOP” to confirm the selection.
   If “dEL ALL” is selected, the unit will display “dell ALL do NE” + User ID and delete all the record of the current user.
   Several seconds later, it will display “—”. If “dell no” is selected, it will stop the deletion.

Systolic pressure and diastolic pressure

When ventricles contract and pump blood out of the heart, the blood pressure reaches its maximum value in the cycle, which is called systolic pressure. When the ventricles  relax, the blood pressure reaches its minimum value in the cycle, which is called diastolic pressure.

Standard blood pressure classification

The blood pressure classification published by AAC/AHA in 2017 is as follows:
CAUTION
Only a physician can tell your normal BP range.Please contact a physician if your measuring result falls out of the range. Please note that only a physician can tell whether  your blood pressure value has reached a dangerous point.

Irregular Heartbeat Detector

An irregular heartbeat is detected when a heartbeat rhythm varies while the unit is measuring the systolic and diastolic blood pressure. During each measurement, the monitor records all the pulse intervals and calculate the average; if there are two or more pulse intervals, the difference between each interval and the average is more than the average  value of ±25%, or there are four or more pulse intervals, the difference between each interval and the average is more than the average value of ±15%, the irregular heartbeat symbol appears on the display when the measurement results are appeared.

CAUTION
The appearance of the IHB icon indicates that a pulse irregularity consistent with an irregular heart-beat was detected during measurement. Usually this is NOT a cause for  concern. However, if the symbol appears often, we recommend you seek medical advice. Please note that the device does not replace a cardiac examination, but serves to detect pulse irregularities at an early stage.

Blood pressure fluctuate throughout the day

1. Individual blood pressure varies multiple times everyday. It is also affected by the way you tie your cuff and your measurement position, so please take the measurement  under the same conditions.
2. If the person takes medicine, the pressure will vary more.
3. Wait at least 3 minutes for another measurement.

Different blood pressure at home compared to the hospital

The blood pressure is different even throughout the day due to weather, emotion, exercise etc. Also, there is the “white coat” effect, which means blood pressure usually  increases in clinical settings.
What you need to pay attention to when you measure your blood pressure at home:
If the cuff is tied properly.
If the cuff is too tight or too loose.
If the cuff is tied on the upper arm.
If you feel anxious.
Taking 2-3 deep breaths before beginning will be better for measuring.
Advice: Relax yourself for 4-5 minutes until you calm down.

Measuring on the right arm

It is ok for both arms, but there will be some different results for different people.
We suggest you measure the same arm every time.
