Using the device for the first time

Inserting the batteries
After you have unpacked your device, first insert the batteries. The battery compartment 9 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

•  After the new batteries are fitted, the year number flashes in the display. You can set the year by pressing the M-button 3. To confirm and then set the month, press the MAM button 4.
•  Press the M-button to set the month. Press the MAM button to confirm and then set the day.
•  Follow the instructions above to set the day, hour and minutes.
•  Once you have set the minutes and pressed the MAM button, the date and time are set and the time is displayed.

If you want to change the date and time, press and hold the  MAM button 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).

• Pre-shaped cuffs are optionally available.
• Only use Microlife cuffs.
• Contact your local Microlife Service if the enclosed cuff AT does not fit.
• Connect the cuff to the device by inserting the cuff connector AK into the cuff socket 6 as far as it will go.
• If you buy A Kspare Microlife cuff, please remove the cuff connector from the cuff tube 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.
• Select the intended user (user 1 or user 2 BN) by pressing the user button 5.
• Before each measurement, ensure that the correct user ism selected.
• Before each measurement, ensure that the correct user is selected.

Selec ting standard or MAM mode
Before each measurement, select standard (single measurement) or MAM mode (automatic triple measurement). 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 obtained in this way is more reliable than when a single measurement is performed.

• To select MAM mode, press the MAM button 4 until the MAM-symbol AP appears on the display. To change to standard mode (single measurement), press the MAM-button again, until the MAM-symbol disappears.
• 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 countdown 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.

 Checklist for taking a reliable measurement

• Avoid activity, eating or smoking immediately before the measurement.
•  Sit down on a back-supported chair and relax for 5 minutes. Keep your feet flat on the floor and do not cross your legs.
• Always measure on the same arm (normally left). It is recommended 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.
• 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.
•  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.

Taking a blood pressure measurement

1. Select standard (single measurement) or MAM mode (automatic triple measurement): see details in chapter 1.»
2.  Press the ON/OFF button 1 to start the measurement.
3.  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.
4.  The cuff fit check AR on the display indicates that the cuff is perfectly placed. If the icon AR-A appears, the cuff is fitted suboptimally, but it is still ok to measure.
5.  The measurement is performed during the inflation. The inflation speed may vary, this is a normal occurrence.
6.  During the measurement, the pulse indicator BM flashes in the display.
7.  The result, comprising the systolic AM and the diastolic AN blood pressure and the pulse rate AO are displayed. Note also the explanations on further display symbols in this booklet.
8.  When the device has finished measuring, remove the cuff.
9.  Switch off the device. (The monitor does switch off automatically after approx. 1 min.).

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).

How not to store a reading
As soon as the reading is displayed press and hold the ON/OFF button 1 until «M» BO is flashing. Confirm to delete the reading by pressing the MAM button 4.
CL» is displayed when the reading is deleted from the reading is deleted from the memory successfully

How do I evaluate my blood pressure
The triangle on the left-hand edge of the display BL points at the range within which the measured blood pressure value lies. The  value is either within the optimum (green), elevated (yellow) or high (red) range. The classification corresponds to the following ranges defined by international guidelines (ESH, ESC, JSH). Data in mmHg.

• The higher value is the one that determines the evaluation.
• Example: a blood pressure value of 140/80 mmHg or a value of  130/90 mmHg indicates «blood pressure too high».

Appearance of the irregular heartbeat (IHB) symbol

• This symbol BT 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.

Data memory

• This device automatically stores up to 99 measurement values for each of the 2 users.
• Select either user 1 or 2 by pressing the user button 5.

Viewing the stored values

• Press the M-button 3 briefly, when the device is switched off. The display first shows «M» BO, 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.
• Blood pressure readings with suboptimal cuff fit AR-A are not considered in the average value.
• Pay attention that the maximum memory capacity of 99 memories is not exceeded. When the 99 memory is full, the oldest value is automatically overwritten with the 100 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.
If you are sure that you want to permanently remove all stored values, hold down the M-button (the device must have been switched off beforehand) until «CL ALL» appears and then release the button. To permanently clear the memory, press the MAM button while «CL ALL» is flashing. Individual values cannot be cleared.
Cancel deletion: press ON/OFF button 1 while «CL  ALL» is flashing.

Battery indicator and battery change

Low battery
When the batteries are approximately ¾ empty the battery symbol AQ 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.
