Introduction

1.1. Your automatic wrist blood pressure monitor

Thank you for purchasing a fully automatic wrist blood pressure monitor. Your monitor is designed to provide fast and reliable digital readings of your pulse, and systolic/diastolic blood pressure using the oscillometric method on your wrist. It offers clinically proven accuracy and has been designed to be user-friendly. Before using your blood pressure monitor, please read this instruction manual carefully to ensure correct use. If you have additional questions regarding blood pressure measurements please contact your doctor.

1.2. Inflation mode technology

Please note that this device employs “Inflation Mode Technology.” This means your blood pressure is measured while the wrist cuff is inflating, rather than first inflating to a  peak pressure, and then measuring during a slow deflation process. With this process, it is a normal occurrence for the inflation speed to vary. This unique technology provides a  faster, more comfortable blood pressure reading for you. If you have any questions about your blood pressure reading or monitor, please call us at 1-888-287-1915.

How is blood pressure measured?

2.1. What is blood pressure, and why does it fluctuate?
Your level of blood pressure is determined in the circulatory center of the brain and adjusts to a variety of situations through feedback from the nervous system. To adjust blood pressure, the strength and frequency of the heart (pulse), as well as the width of circulatory blood vessels is altered.
Blood vessel width is affected by way of fine muscles in the blood vessel walls. Your level of arterial blood pressure changes periodically during heart activity. During the “blood  ejection” (Systole), the value is highest (systolic blood pressure value). At the end of the heart’s “rest period” (Diastole), pressure is lowest (diastolic blood pressure value). Your blood pressure values must lie within certain normal ranges in order to prevent particular diseases.
2.2. Measurement guidelines
Blood pressure is very high if your systolic blood pressure is over 160 mmHg and/or your diastolic pressure is above 100 mmHg, while at rest. In this case, please consult your
physician immediately. Long-term values at this level endanger your health due to continual damage to the blood vessels in your body. If your systolic blood pressure values are between 140 mmHg and 159 mmHg and/or the diastolic blood pressure values are between 90 mmHg and 99 mmHg, consult your physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values under 105 mmHg and/or diastolic values under 60 mmHg), consult your physician. Even with normal blood pressure values, a regular self-check with your blood pressure monitor is recommended. You can detect possible changes in your values early and react appropriately.
If you are undergoing medical treatment to control your blood pressure, keep a record of values along with time of day and date. Show these values to your physician.
Never use the results of your measurements to independently alter the medication prescribed by your physician.
Which values are normal?
The following standards for assessing high blood pressure (in adults) have been established by the American Heart Association (AHA) and American College of Cardiology (ACC) in 2017.

Hypertension
Stage 1 Hypertension| 130-139| or80
Stage 2 Hypertension| 140-179| 90-119
H hypertensive Crisis| ≥180| or≥120

Additional information

• If your values are mostly normal under resting conditions but exceptionally high under conditions of physical or psychological stress, it is possible that you are suffering from
  so-called “labile hypertension.” Consult your physician.
  2.3. What can I do to change my blood pressure?
  a). Consult your physician.
  b). Increased blood pressure values (various forms of hypertension) are associated with considerable health risks over time. Arterial blood vessels in your body are endangered
  due to constrictions caused by deposits in the vessel walls (arteriosclerosis). A deficient supply of blood to important organs (heart, brain, muscles) can result. Furthermore, the
  heart will become structurally damaged with increased blood pressure values.
  c). There are many different causes of high blood pressure. We differentiate between common primary (essential) hypertension and secondary hypertension. Secondary
  hypertension can be ascribed to specific organ malfunctions. Please consult your physician for information about the possible origins of your own increased blood pressure values.
  d). There are measures you can take to reduce and even prevent high blood pressure. These measures must be permanent lifestyle changes.

1) Eating habits

• Strive for a normal weight corresponding to your age. See your doctor for your ideal weight.
• Avoid excessive consumption of common salt.
• Avoid fatty foods.

2) Previous illnesses
Follow consistently any medical instructions for treating illness such as:

• Diabetes (diabetes mellitus)
•  Fat metabolism disorder
• Gout

3) Habits

• Give up smoking completely.
• Drink only moderate amounts of alcohol.
• Restrict your caffeine consumption (e.g., coffee).

4) Physical constitution

• After a preliminary medical examination, do regular exercise.
•  Choose sports that require stamina and avoid those which require strength.
•  Avoid reaching the limit of your performance.
•  With previous illnesses and/or age of over 40 years, please consult your doctor before beginning your exercise routine. He will advise you regarding the type and extent of exercise that is appropriate for you.

How do I get started?

4.1. Inserting the batteries
After you have unpacked your device, insert the batteries. The battery compartment is located on the side of the device.
a). Remove the battery cover.
To open the battery cover: Turn the monitor over, locate the pull-on cover and use your fingertip to pull it towards you. To close battery cover: Align cover in the battery compartment at approximately a 15-degree angle, inserting the tabs into the holes found on the inside. Once the back of the cover has been seated, push down on the battery
cover pull.
b). The door will click into place.
c). Insert the batteries (2 x size AAA 1.5 V), following the indicated polarity.
If the battery warning appears in the display, the batteries are discharged and must be replaced with new ones.
Attention!
• After the low battery indication warning appears, the device will not function until the batteries have been replaced.
• Please use “AAA” Long Life or Alkaline 1.5V batteries. When replacing batteries, replace all at the same time, and ensure they are correctly connected, as shown on the symbols in the compartment.
If the blood pressure monitor is left unused for long periods, remove the batteries from the device.
4.2. Selecting standard or MAM mode
Before each measurement, select standard (single measurement) or MAM mode (automatic double measurement). In MAM mode, 3 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, 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 Heart Level 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, 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, an additional measurement is automatically taken.

4.3. Selecting Heart Level 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. Incorrect wrist position might lead to an inaccurate result. Follow the instruction of the Heart Level Indicator to make sure the wrist height is the same level as the heart.

• After the MAM mode is selected, the Heart Level Indicator ON/OFF selection will appear on the display. Press the M-button to select ON or OFF the Heart Level 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 to 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 to repeat the measurement to make sure to get an accurate result.

4.4. Setting the date and time

• After selecting the Heart Level Indicator, the year number flashes in the display. You can set the year by pressing the M-button. To confirm and then set the month, press the time button.
• Press the M-button to set the month. Press the time 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 time 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 time button down for approx. 3 seconds to enter the setting menu. Press time button twice to skip MAM mode/ Heart Level Indicator setting until the year number starts to flash. Now you can enter the new values as described above.

4.5. Setting the user
This device allows 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.

5. How do I take a measurement?
Please note: You should always be seated before and during the measurement.
5.1. Preparing to take a measurement

• Avoid activity, eating or smoking immediately before the measurement.
• 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.
• Always measure in a sitting position and on the same wrist. Use the wrist which usually shows higher blood pressure values.
•  Remove any items of clothing and your watch, for example, so that your wrist is free.
• Always ensure that the cuff is positioned correctly, as shown in the pictures illustrated on the short instruction card.
• Fit the cuff comfortably but not too tight. The cuff will cover a wrist circumference of 13.5 – 23 cm (5.25 – 9.06 inches).
• Support your arm in a relaxed position and ensure that the device is at the same height as your heart.

5.2. Common errors
Note:
Comparable blood pressure measurements always require the same conditions. These are normally always quiet conditions.

• All efforts to support the arm can increase blood pressure. Make sure you are in a comfortable, relaxed position and do not flex any of the muscles in the measurement arm
  during the measurement. Use a cushion for support if necessary.

•  If the wrist artery lies considerably lower (higher) than the heart, an erroneously higher (lower) blood pressure will be measured. (Each 15 cm/6″ difference in height results in a measurement error of 10 mmHg.)

• A loose cuff causes false measurement values.

• With repeated measurements, blood can accumulate in the respective arm, which can lead to false results. Correctly executed blood pressure measurements should therefore first be repeated after a 1-minute pause or after the arm has been held up in order to allow the accumulated blood to flow away.

5 .3. Taking a measurement

• Select standard (single measurement) or MAM mode (automatic double measurement): see details in chapter 4.2
• Press the ON/OFF button to start the measurement.
•  After Heart Level Indicator is checked (see details in chapter 4.3), 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.
•  The Cuff Fit Check on the display indicates that the cuff is perfectly placed. If the icon 15-A appears, the cuff is fitted suboptimally, but it is still ok to measure.
• The measurement is performed during inflation. The inflation speed may vary, this is a normal occurrence.
• During the measurement, the pulse indicator flashes in the display.
•  The result, comprising the systolic and the diastolic blood pressure and the pulse rate is displayed. Note also the explanations on further display symbols in this booklet.
• 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 an unpleasant pressure sensation).

5.4. Stopping a measurement

If it is necessary to interrupt a blood pressure measurement for any reason (e.g., the patient feels unwell), the POWER button can be pressed at any time. The device then immediately lowers the cuff pressure automatically and enters into sleep mode.

5.5. Appearance of the Irregular Heartbeat (IHB) Symbol

This symbol 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 frequent appearance of the IHB symbol

This device is an oscillometric blood pressure monitor that also analyses pulse irregularity during measurement. The IHB 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 briefly, when the device is switched off. The display first shows «M» and «A», which stands for the average of the last 3 measurements in memory.
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 15-A are not considered in the average value.
Memory full
Pay attention that the maximum memory capacity of 99 memories is not exceeded. When value. Values should be evaluated by a doctor before the memory capacity is reached – otherwise data will be lost. the 99 memory is full, the oldest value is automatically overwritten with the 100 th
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 time button while «CL ALL» is flashing. Individual values cannot be cleared.
Cancel deletion: press the ON/OFF button while «CL ALL» is flashing.

   Battery charge indicator

• Low battery
  When the batteries are approximately ¾ empty the battery symbol 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 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 at the back of the device.
2. Replace the batteries – ensure correct polarity as shown by the symbols in the compartment.
3. To set a date and time, follow the procedure described in «Section 5.».
   The memory retains all values although date and time must be reset – the year number, therefore, flashes automatically after the batteries are replaced (after MAM mode and Heart Level Indicator setting).

Which batteries and which procedure?
Use 2 new, long-life 1.5 V, size AAA 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.
