This system stores blood pressure measurements for up to four users. Each user’s test results are stored separately under each user number.

1. Press  to select the desired user number.
2. Press  to confirm. The monitor will repeat the selected user number and then turn off automatically

TESTING YOUR BLOOD PRESSURE

BEFORE MEASUREMENT

• Avoid caffeine, tea, alcohol and tobacco for at least 30 minutes before measurement.

• Wait 30 minutes after exercising or bathing before measurement.

• Sit or lie down for at least 10 minutes before measuring.

• Do not measure when feeling anxious or tense.

• Take a 5-10 minutes break between measurements.
  This break can be longer if necessary, depending on your physical condition.

• Keep the records for your healthcare provider as reference.

• Blood pressure naturally varies between each arm.
  Always measure your blood pressure on the same arm.

FITTING THE CUFF PROPERLY

1. Connect the air plug of the tubing to the air jack of the meter.

2. Assemble the cuff as shown. The smooth surface should be inside of the cuff loop and the metal D-ring should not touch your skin.

3. Stretch your left (right) arm in front of you with your palm facing up. Slide and place the cuff onto your arm with the air tube and artery mark region toward the lower arm.
   Wrap and tighten the cuff above your elbow. The bottom edge of the cuff should be approximately 0.8” to 1.2” (2 cm to 3 cm) above your elbow. Align the tube over the main arteries on the inside.

4. Leave a little free space between the arm and the cuff; you should be able to fit two fingers between them. Clothing must not restrict the arm. Remove all clothing covering or constricting the measurement arm.The range index of cuff should fall within this range

5. Press the hook material firmly against the pile material. The top and bottom edges of the cuff should be tightened evenly around your upper arm.

PROPER MEASUREMENT POSITION

1. Sit down for at least 10 minutes before measuring.

2. Place your elbow on a flat surface. Relax your hand with the palm facing up.

3. Make sure the cuff is about the same height as the location of your heart.
   Press Remain still and do not talk or move during the measurement.
   WARNING
   If the cuff is relatively lower (higher) than the heart, the obtained blood pressure value could be higher (lower) than the actual value. A 15 cm difference in height may result in an error around 10 mmHg.

4. Measurement is in progress. After the meter is turned on, the cuff will begin to inflate automatically.

TAKING MEASUREMENTS

Always apply the pressure cuff before turning on the meter.

1. Press All the LCD symbols will appear. Press to select user (numbers from 1 to 4) whose test reading will be stored in its memory.
   Then the cuff will begin to inflate automatically.

2. The heart symbol “ ” will flash when pulse is detected during the measurement.

3. After the measurement, the meter displays the systolic pressure, diastolic pressure and pulse rate.

4. Press to switch off or it will switch off automatically after being  idle for 3 minutes.

5. The meter will enter Bluetooth mode automatically.

NOTE

• If you press during measurement, the meter will be turned off.
• If the pulse rate symbol is shown as “ ” instead of “ ”, this indicates that the meter has detected an irregular heart beat.

AVERAGING MEASUREMENT MODE

Always apply the pressure cuff before turning on the meter.

1. Press and hold until the meter displays “AVERAGE”, then Press to select user (numbers from 1 to 4) whose test reading will be stored in its memory. Then the cuff will begin to inflate automatically.
2. After the first measurement is completed, the meter will start counting down before the second measurement begins. The number on the right represents the remaining countdown between each measurement. The meter will take three (3) measurements consecutively with intervals of 20 seconds.
3. After taking three measurements, the results are averaged to produce the blood pressure measurement with “AVERAGE” symbol display on the meter. Press to turn off the meter.

METER MEMORY

Your meter stores the 400 most recent blood pressure test results along with respective dates and times in the meter memory. To recall the memory, start with the meter off.

REVIEWING TEST RESULTS

1. Press and release M
   The user symbol (numbers from1 to 4) appears first, press to select which one you used to store in the memory. Press again, and the first reading you see is the last blood pressure result along with date and time.

2. Press M again, and the first reading you see is the last blood pressure result along with date and time.

DETAILED INFORMATION

REFERENCE VALUES

Clinical studies show that adult diabetes is often accompanied by elevated blood pressure. People with diabetes can reduce their heart risk by managing their blood pressure along with diabetes treatment” Monitoring your routine blood pressure trend helps you to know your body condition. Human blood pressure naturally increases after reaching middle age. This symptom is a result of continuous ageing of the blood vessels. Further causes include obesity, lack of exercise and cholesterol (LDL) adhering to the blood vessels. Rising blood pressure accelerates hardening of the arteries, and the body becomes more susceptible to apoplexy and coronary infarction. Categories of blood pressure in adults?:

Blood Pressure Category| Systolic Blood Pressure (mmHg)| | Diastolic Blood Pressure (mmHg)
---|---|---|---
Normal| Less than 120 mmHg| and| Less than 80 mmHg
Elevated| 120-129 mmHg| and| Less than 80 mmHg
Hypertension| | |
Stage 1| 130-139 mmHg| or| 80-89 mmHg
Stage 2| 140 mmHg or more| or| 90 mmHg or more

Individuals with systolic blood pressure and diastolic blood pressure in two categories should be designated to the higher blood pressure category.

If necessary to achieve the IMMUNITY TEST LEVEL, the distance between the transmitting antenna and the ME EQUIPMENT or ME SYSTEM may be reduced to 1 m. The 1 m test distance is permitted by IEC 61000-4-3.
For some services, only the uplink frequencies are included.
The carrier shall be modulated using a 50 % duty cycle square wave signal.
As an alternative to FM modulation, 50 % pulse modulation at 18 Hz may be used because while it does not represent actual modulation, it would be worst case.
