Important Facts about Blood Pressure and Self-Measurement

• Blood pressure is the pressure of the blood flowing in the arteries generated by the pumping of the heart. Two values, the systolic (upper) value and the diastolic (lower) value, are always measured.
• The device indicates the pulse rate (the number of times the heart beats in a minute).
• Permanently high blood pressure values can damage your health and must be treated by your doctor!
• Always discuss your values with your doctor and tell him/her if you have noticed anything unusual or feel unsure. Never rely on single blood pressure readings.
• There are several causes of excessively high blood pressure values. Your doctor will explain them in more detail and offer treatment where appropriate. Besides medication, weight loss and exercise can also lower your blood pressure.
• Under no circumstances should you alter the dosages of drugs or initiate a treatment without consulting your doctor.
• Depending on physical exertion and condition, blood pressure is subject to wide fluctuations as the day progresses. You should therefore take your measurements in the same quiet conditions and when you feel relaxed! Take at least two readings every time (in the morning and in the evening) and average the measurements.
• It is quite normal for two measurements taken in quick succes-sion to produce significantly different results. Therefore we recommend using the MAM technology.
• Deviations between measurements taken by your doctor or in the pharmacy and those taken at home are quite normal, as these situations are completely different.
• Several measurements provide much more reliable information about your blood pressure than just one single measurement. Therefore we recommend using the MAM technology.
• Leave a small break of at least 15 seconds between two measurements.
• If you suffer from a cardiac arrhythmia consult with your doctor before using the device. See also chapter «Appearance of the Irregular Heartbeat (IHB) Symbol» of this user manual.
• The pulse display is not suitable for checking the frequency of heart pacemakers!
• If you are pregnant, you should monitor your blood pressure regularly as it can change drastically during this time.

This monitor is specially tested for use in pregnancy and pre-eclampsia. When you detect unusual high readings in pregnancy, you should measure after a short while again (eg. 1 hour). If the reading is still too high, consult your doctor or gynecologist.

Using the Device for the First Time

Inserting the Batteries

After you have unpacked your device, first insert the batteries. The battery compartment 4 is on the bottom of the device. Insert the batteries (4 x 1.5 V, size AA), thereby observing the indicated polarity.

Setting the Date and Time

1. After the new batteries are fitted, the year number flashes in the display. You can set the year by pressing the M-button AK. To confirm and then set the month, press the time button AL.
2. Press the M-button to set the month. Press the time button to confirm and then set the day.
3. Follow the instructions above to set the day, hour and minutes.
4. Once you have set the minutes and pressed the time button, the date and time are set and the time is displayed.
5. If you want to change the date and time, press and hold the time button down for approx. 3 seconds until the year number starts to flash. Now you can enter the new values as described above.

Selecting the Correct Cuff

Microlife offers different cuff sizes. Select the cuff size to match the circumference of your upper arms (measured by close fitting in the centre of the upper arm).

Cuff Size

|

For Circumference of Upper Arm

---|---

M

| 22 – 32 cm
M – L|

22 – 42 cm

L

|

32 – 42 cm

• Pre-shaped cuffs are optionally available.

• Only use Microlife cuffs.

• Contact your local Microlife Service if the enclosed cuff 6 does not fit.

• Connect the cuff to the device by inserting the cuff connector 7 into the cuff socket 3 as far as it will go.

If you buy a spare Microlife cuff, please remove the cuff connector 7 from the cuff tube AL from the cuff supplied with the original device and insert this cuff connector into the tube of the spare cuff (valid for all cuff sizes).

Selecting the User

This device allows to store the results for 2 individual users.

• Before each measurement, set the user switch AT for the intended user: user 1 or user 2.
• User 1: slide the user switch AT upwards to the user 1 icon.
• User 2: slide the user switch AT downwards to the user 2 icon.

The first person to measure should select user 1.

Selecting Standard or MAM Mode

This device enables you to select either standard (standard single measurement) or MAM mode (automatic triple measurement). To select standard mode, slide the MAM switch 9 on the side of the device downwards to position «1» and to select MAM mode, slide this switch upwards to position «3».

MAM Mode (Highly Recommended)

• In MAM mode, 3 measurements are automatically taken in succession and the result is then automatically analysed and displayed. Because the blood pressure constantly fluctuates, a result determined in this way is more reliable than one produced by a single measurement.
• When you select the 3 measurements, the MAM-symbol BM appears in the display.
• The bottom, right hand section of the display shows a 1, 2 or 3 to indicate which of the 3 measurements is currently being taken.
• There is a break of 15 seconds between the measurements. A count down indicates the remaining time.
• The individual results are not displayed. Your blood pressure will only be displayed after all 3 measurements are taken.
• Do not remove the cuff between measurements.
• If one of the individual measurements was questionable, a fourth one is automatically taken.

Taking a Blood Pressure Measurement

Checklist for Taking a Reliable Measurement

1. Avoid activity, eating or smoking immediately before the measurement.

2. Sit down on a back-supported chair and relax for 5 minutes. Keep the feet flat on the floor and do not cross your legs.

3. Always measure on the same arm (normally left). It is recom-mended that doctors perform double arm measurements on a patients first visit in order to determine which arm to measure in the future. The arm with the higher blood pressure should be measured.

4. Remove close-fitting garments from the upper arm. To avoid constriction, shirt sleeves should not be rolled up – they do not interfere with the cuff if they are laid flat.

5. Always ensure that the correct cuff size is used (marking on the cuff).

   • Fit the cuff closely, but not too tight.
   • Make sure that the cuff is positioned 1-2 cm above the elbow.
   • The artery mark on the cuff (ca. 3 cm long bar) must lie over the artery which runs down the inner side of the arm.
   • Support your arm so it is relaxed.
     Ensure that the cuff is at the same height as your heart.

6. Press the ON/OFF button 1 to start the measurement.

7. The cuff will now pump up automatically. Relax, do not move and do not tense your arm muscles until the measurement result is displayed. Breathe normally and do not talk.

8. The measurement is performed during the inflation. The infla-tion speed may vary, this is a normal occurence.

9. During the measurement, the pulse indicator BK flashes in the display.

10. The result, comprising the systolic AP and the diastolic AQ blood pressure and the pulse rate AR is displayed. Note also the explanations on further display symbols in this booklet.

11. When the device has finished measuring, remove the cuff.

12. Switch off the device. (The monitor does switch off automati-cally after approx. 1 min.).

How Not to Store a Reading

As soon as the reading is displayed press and hold the ON/OFF button 1 until «M» BP is flashing. Confirm to delete the reading by pressing the M-button AK.

• You can stop the measurement at any time by pressing the ON/OFF button (e.g. if you feel uneasy or an unpleasant pressure sensation).

Appearance of the Irregular Heartbeat (IHB) Symbol

This symbol indicates that an irregular heartbeat was detected. In this case, the measured blood pressure may deviate from your actual blood pressure values. It is recommended to repeat the measurement.

Information for the doctor in case of repeated appearance of the IHB symbol:
This device is an oscillometric blood pressure monitor that also measures the pulse during blood pressure measurement and indicates when the heart rate is irregular.

Traffic Light Indicator in the Display

The bars on the left-hand edge of the display AS show you the range within which the indicated blood pressure value lies. Depending on the height of the bar, the readout value is either within the optimum (green), elevated (yellow), too high (orange) or dangerously high (red) range. The classification corresponds to the 4 ranges in the table as defined by the international guidelines (ESH, ESC, JSH), as described in «Section 1.».

PC-Link Functions

This device can be used in conjunction with a personal computer (PC) running the Microlife Blood Pressure Analyzer+ (BPA+) soft-ware. The memory data can be transferred to the PC by connecting the monitor via a cable. If no download-voucher and cable is included download the BPA+ software from www.microlife.com/software and use a USB cable with a Mini-B 5 pin connector.

• During the connection, the device is completely controlled by the computer.

Data Memory

This device automatically stores up to 99 measurement values for each of the 2 users.

Viewing the Stored Values

Select either user 1 or 2 with the user switch AT.
Press the M-button AK briefly, when the device is switched off. The display first shows «M» BP and «A», which stands for the average of all stored values.
Pressing the M-button again displays the previous value. Pressing the M-button repeatedly enables you to move from one stored value to another.

Memory Full

• Pay attention that the maximum memory capacity of 99 memories per user is not exceeded. When the 99 memory is full, the oldest value is automatically overwritten with the 100th value. Values should be evaluated by a doctor before the memory capacity is reached – otherwise data will be lost.

Clearing All Values

Make sure the correct user is activated.

1. Select either user 1 or 2 with the user switch AT, when the device is switched off.
2. Hold down the M-button AK until «CL» appears and then release the button.
3. Press the M-button while «CL» is flashing to permanently clear all values of the selected user.

• Cancel deletion: press ON/OFF button 1 while «CL» is flashing.
• Individual values cannot be cleared.

Battery Indicator and Battery Change

Low Battery

When the batteries are approximately ¾ empty the battery symbol AN will flash as soon as the device is switched on (partly filled battery displayed). Although the device will continue to measure reliably, you should obtain replacement batteries.

Flat Battery – Replacement

When the batteries are flat, the battery symbol AN will flash as soon as the device is switched on (flat battery displayed). You cannot take any further measurements and must replace the batteries.

1. Open the battery compartment 4 on the bottom of the device.
2. Replace the batteries – ensure correct polarity as shown by the symbols in the compartment.
3. To set date and time, follow the procedure described in «Section 2».

• The memory retains all values although date and time must be reset – the year number therefore flashes automatically after the batteries are replaced.

Which batteries and which procedure?

• Use 4 new, long-life 1.5 V, size AA alkaline batteries.
• Do not use batteries beyond their date of expiry.
• Remove batteries if the device is not going to be used for a prolonged period.

Using Rechargeable Batteries

You can also operate this device using rechargeable batteries.

• Only use «NiMH» type reusable batteries.
• Batteries must be removed and recharged when the flat battery symbol appears. They should not remain inside the device as they may become damaged (total discharge as a result of low use of the device, even when switched off).
• Always remove the rechargeable batteries if you do not intend to use the device for a week or more.
• Batteries cannot be charged in the blood pressure monitor. Recharge batteries in an external charger and observe the information regarding charging, care and durability.
