• This device is tested according to the ESH protocol and ISO81060-2:2013.

Using the Device for the First Time

Inserting the batteries
After you have unpacked your device, first insert the batteries. Battery compartment 5 is on the bottom of the device. Insert the batteries (2 x 1.5 V, size AAA), thereby observing the indicated polarity.
Selecting standard or MAM mode
Before each measurement, select standard (single measurement) or MAM mode (automatic double measurement). In MAM mode, 2 measurements are automatically taken in succession and the result is then automatically analyzed and displayed. Because the blood pressure constantly fluctuates, a result obtained in this way is more reliable than when a single measurement is performed.

• After the new batteries are fitted, the Smart MAM mode ON/OFF selection will appear on the display first. Press the M-button to select ON or OFF the MAM mode. Press the Time Button to confirm and then select the Wrist Position Indicator. To change to standard mode (single measurement), press the Time Button until the MAM mode selection menu appears and select OFF.

• The bottom, right-hand section of the display shows a 1 or 2 to indicate which of the 2 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 2 measurements are taken.

• Do not remove the cuff between measurements.

• If one of the individual measurements was questionable, an additional measurement is automatically taken.
  Selecting Wrist Position Indicator
  Keeping the wrist at the same height level as the heart during measurement is one of the most important facts to use a wrist blood pressure monitor. An incorrect wrist position might lead to an inaccurate result. Follow the instruction of the Wrist Position Indicator to make sure the wrist height is the same level as the heart.

• After the MAM mode is selected, the Wrist Position Indicator ON/OFF selection will appear on the display. Press the M-button to select ON or OFF the Wrist Position Indicator. Press the Time Button to confirm and then enter the date and time setting.

• There are 5 levels of height detection plus a blue LED indicator to help the user determine if the monitor is at the correct height.

• When the monitor is at a higher position relative to your heart, 1 or 2 downward arrow(s) appear to remind you to lower the wrist slowly until the blue LED is lighted with a heart symbol. Conversely, 1 or 2 upward arrow(s) appear when your wrist height is lower than heart level and raise the wrist higher as an indication.

• Adjust your wrist to the correct height level and keep about 2 sec, the monitor will start measurement automatically.

• Please retain this wrist height during measurement, and do not move even in the interval time of MAM mode until the result is displayed on the LCD.

• The blue LED will blank off during measurement to save the battery power and appear again with the result when the measurement is finished.

• If the user doesn’t adjust the wrist at the correct heart level in time (about 9 sec), the monitor will still start measurement with upward/downward arrows as an indication. However, we recommend repeating the measurement to make sure to get an accurate result.
  Caution: The Wrist Position Check is only an approximate indication, and may not be accurate for all users because of differences in individual physique and size. If you are unable to make your seat or table adjustments and find the height of the wrist is not the same as your heart level obviously, please turn off the Wrist Position Check feature and position your wrist at heart level by yourself.

Setting the date and time

1. After selecting the Wrist Position Indicator, the year number flashes on the display. You can set the year by pressing the M-button3. to confirm and then set the month, press the time button4.
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 to enter the setting menu. Press the time button twice to skip MAM mode/ Wrist Position
   Indicator setting until the year number starts to flash. Now you can enter the new values as described above.

Setting the user
This device allows to the storage of the results for 2 individual users.

• Select the intended user (user 1 or user 2) by pressing the time button.

**** Before each measurement, ensure that the correct user is selected.

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. Adjust your seat height to make sure the distance between your seat and the top of the table is within 30 ± 5 cm (12 ± 2 inches).
3. Always measure in a sitting position and on the same wrist. Use the wrist which usually shows higher blood pressure values.
4.  Remove any items of clothing and your watch, for example, so that your wrist is free.
5. Always ensure that the cuff is positioned correctly.
6. Fit the cuff comfortably but not too tight. The cuff will cover a wrist circumference of 13.5 – 21.5 cm (5.25 – 8.5 inches).
7. Support your arm in a relaxed position and ensure that the device is at the same height as your heart.

Taking a Blood Pressure Measurement

1. Select standard (single measurement) or MAM mode (automatic double measurement): see details in chapter«1».

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

3. After the Wrist Position Indicator is checked (see details in chapter «1»), 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 AO on the display indicates that the cuff is perfectly placed. If the icon AO-A appears, the cuff is fitted suboptimally, but it is still ok to measure.

5. The measurement is performed during inflation. The inflation speed may vary, this is a normal occurrence.

6.  During the measurement, the pulse indicator AP flashes in the display.

7. The result, comprising the systolic 7 and the diastolic 8 blood pressure and the pulse rate 9 is displayed. Note also the explanations on further display symbols in this booklet.

8. Remove and switch off the monitor. (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 have 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» AK is flashing. Confirm to delete the reading by pressing the time button 4.
**** «CL» is displayed when 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 AL 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. For example, a blood pressure value of 140/80 mmHg or a value of 130/90 mmHg indicates «blood pressure too high».

The appearance of the Pulse Arrhythmia (PAD)
This symbol AM indicates that certain pulse irregularities were detected during the measurement. In this case, the result may deviate from your normal blood pressure – repeat the measurement. In most cases, this is no cause for concern. However, if the symbol appears on a regular basis (e.g. several times a week with measurements taken daily)
we advise you to tell your doctor. Please show your doctor the following explanation:

Information for the doctor on the frequent appearance of the PAD symbol
This device is an oscillometric blood pressure monitor that also analyses pulse irregularity during measurement. The device is clinically tested.
The PAD symbol is displayed after the measurement if pulse irregularities occur during measurement. If the symbol appears more frequently (e.g. several times per week on measurements performed daily) we recommend the patient to seek medical advice.

This device does not replace a cardiac examination but serves to detect pulse irregularities at an early stage.

Data Memory

This model is designed for two users and can store up to 99 blood pressure readings for each user.
Select either user 1 or 2 by pressing the time button.
Viewing the stored values
Press the M-button 3 briefly, when the device is switched off. The display first shows «M» AK 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 AO-A are not considered in the average value.

Memory full
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 100th
value.

Values should be evaluated by a doctor before the memory capacity is reached – otherwise data will be lost.

Clearing all values
If you are sure that you want to permanently remove all stored Make sure the correct user is activated.
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 time 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.
