6. To bypass setting date and time, press the time area of the touch

Select the user

This blood pressure monitor is designed to store 120 measurements for each of the two users. Memories are not stored in guest mode.

Before taking a measurement, be certain that the correct user has been selected.
a) With the monitor unlocked, press and hold the user icon, then release.
b) The user icon will begin to blink. Tap again to change users.
c) To confirm your selection wait 3 seconds, or press STOP.

Select measuring mode: standard or Microlife Averaging Mode (MAM)

This instrument enables you to select either standard (single measurement) or measurement averaging mode (automatic triple measurement).
a) To select Standard mode, push the switch on the side of the monitor to Position “1.”
b) To select Averaging mode, push the switch to Position
“3.” Note the “MAM” icon will illuminate on the screen.
If you select 1, then only one measurement will be taken.
If you select 3, the unit will inflate and deflate three times resulting in one final averaged measurement.

 Microlife Averaging Mode (MAM)

• In Microlife Averaging Mode (MAM), three measurements are automatically taken in succession and the result is then automatically analyzed Because your blood pressure constantly fluctuates, a result determined in this way is more reliable than one produced by a single measurement.
• After pressing the START button the selected Microlife Averaging Mode appears in the display as the MAM symbol.
• The bottom section of the display shows a 1, 2, or 3 to indicate which of the 3 measurements is currently being

3.9. Connecting the cuff and monitor

Insert the yellow cuff tube connector into the yellow socket on the left side of the instrument.
If your cuff connector is another color, please contact customer service as additional steps are needed to obtain an accurate reading.

Using the AC power adapter

You may also operate this monitor using the included AC adapter. Use only the included AC adapter to avoid damaging the unit.
a) Ensure that the AC adapter and cable are not damaged.
b) Plug the adapter cable into the AC adapter port on the right side of the monitor.
c) Plug the AC adapter into a 110 V power socket (the U.S. or Canada).
d) Test that power is available by pressing the START button.

Note:

• No power is taken from the batteries while the AC adapter is connected to the instrument.
• f the power is interrupted during a measurement (e.g., by removal of the adapter from the wall socket), the instrument must be reset by removing the plug from the instrument.

If you have any questions regarding the AC adapter, call us at 1-800-568-4147.

How do I take a measurement?

Please note: You should always be seated before and during measurement.

 Preparing to take a measurement

• Avoid eating and smoking as well as all forms of exertion directly before measurement. These factors influence the measurement result. Find time to relax by sitting in an armchair in a quiet atmosphere for about 5 minutes before your measurement.
• Remove any garment that fits closely to your upper arm.
• Always measure on the same arm (normally left).
• Compare measurements at the same time of day, since blood pressure changes during the course of the day (as much as 20–40 mm Hg).

Common errors

Note: Comparable blood pressure measurements always require the same conditions. Conditions should always be quiet.

• All efforts by the user to support the arm can increase blood 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 arm artery lies considerably lower or higher than the heart, erroneously high or low blood pressure will be Each 15 cm (6”) difference in height between your heart and the cuff results in a measurement error of 10 mm Hg.
• Cuffs that are too narrow or too short result in false measurement Selecting the correct cuff is extremely important. Cuff size is dependent upon the circumference of the arm (measured in the center). The permissible range is printed on the cuff. If this is not suitable for your use, please call 1-800-568-4147.
• A loose cuff or a sideways protruding air pocket causes false measurement
• With repeated measurements, blood accumulates in the arm, which can lead to false results. Consecutive blood pressure measurements should be repeated after a 1-minute pause or after your arm has been held up in order to allow the accumulated blood to flow away

Using the cuff

a) Pass the end of the cuff through the flat metal ring so that a loop is formed. The hook and loop material must be facing outward. (Ignore this step if the cuff has already been  prepared.)
b) Slide the cuff onto your upper left arm.
The rubber tube should be on the inside of your arm extending down to your hand. Make certain the cuff lies approximately ½”  (1 to 2 cm) above the elbow.

IMPORTANT: The red stripe on the edge of the cuff (Artery Mark) must lie over the artery which runs down the inner side of the arm.

TIP: Align red artery mark to the pinky finger.

c) To secure the cuff, wrap it around your arm and press the hook and loop material together. Check the position of the green SIZING SEAM on the cuff. Ensure green sizing seam overlaps green size range bar.

d) There should be little free space between the arm and the cuff. You should be able to fit 2 fingers between your arm and the cuff. Clothing must not restrict the arm. Any piece of clothing which does must be removed. Cuffs that don’t fit properly result in false measurement values. Measure your arm circumference if you are not sure of proper fit.

e) Lay your arm on a table so the cuff is at the same height as your heart. Make sure your arm is relaxed and the tube is not kinked.
f) Remain seated quietly for 5 minutes before you begin the measurement.

Comment

If it is not possible to fit the cuff to your left arm, it can also be placed on your right arm. However, all measurements should be made using the same arm. Comparable blood pressure measurements always require the same conditions (relax for several minutes before a reading).

Taking a measurement

After the cuff has been appropriately positioned the measurement can begin. Remain still during your measurement, do not flex muscles, and refrain from talking.
a) Remain seated quietly for 5 minutes before you begin the measurement.

b) Press the START button. After the system check, the monitor displays OK and the pump begins to inflate the cuff. On the display, the increasing cuff pressure is continually shown.
c) After automatically reaching an individual pressure, the pump stops and the pressure will deflate slowly. The cuff pressure is displayed during the measurement.

d) When the device has detected your pulse, the heart symbol in the display begins to blink.
e) When the measurement has been concluded, the air will automatically release from the cuff. The measured systolic and diastolic blood pressure values, as well as the pulse, are now displayed.

f) The measurement results are displayed until you switch the device off. If no button is pressed for 1 minute, the device switches off automatically.
g) When the unit is set to the MAM (Microlife Averaging Mode) setting, 3 separate measurements will take place in succession, after which your result is calculated and displayed as a single, averaged measurement (individual results are not displayed). There is a 15 second resting time between each measurement. A count-down indicates the remaining time between measurements.

If one of the measurements causes an error message, it will be repeated one more time. If any additional error occurs, the measurement will be discontinued and the error code displayed.

 Memory: Reviewing readings

At the end of a measurement, this monitor automatically stores each result with a date and time. This unit stores 120 memories for each of the 2 users.

Viewing the stored values

• With the unit unlocked, press “M.” The display first shows “A,” then shows an average of all measurements stored in the unit for that user.

• Press the M icon to scroll between stored readings.
  Please note: Measurements for each user are averaged and stored separately. Be certain that you are viewing the measurements for the correct user.

• To exit, press STOP.

Memory full
When the memory has stored 120 results, a new, measured value is stored by overwriting the oldest value.

Clear all values

• If you are sure that you want to permanently remove all stored values, hold down “M” until “CL” appears and then release “M”.
• To continue and erase the values, press “M” again while “CL” is flashing.
• To discontinue the clearing of memories, press “STOP.”
• Individual values cannot be cleared.

Stopping a measurement

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

Hypertension risk indicator

The bars on the left-hand edge of the display show the possible range for a blood pressure reading. The reading can fall within the normal (green), borderline (yellow) or danger  (orange, dark orange) range.
The classification is based on standards established by the American Heart Association (AHA) and the American College of Cardiology (ACC) in 2017. Refer to the chart in section  7.2 of this instruction manual for details of the classifications.

A triangle is displayed to the right of the traffic light bar according to your measurement. If the display shows a triangle in the:

• green zone , your measurement is “Normal.”
• lower yellow zone , it is “Elevated.”
• upper yellow zone , it is “Stage 1 “
• orange zone , it is “Stage 2 ”
• lower dark orange zone , it is “Stage 2 ”
• upper dark orange zone , it is “Hypertensive “

 Irregular heartbeat detector

The appearance of this symbol indicates that certain pulse irregularities were detected during the measurement. In this case, the result may deviate from your normal basal 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 on the frequent appearance of the irregular heartbeat symbol
This instrument is an oscillometric blood pressure monitor device that also analyzes pulse frequency during measurement. The instrument is clinically tested.
If pulse irregularities occur during the measurement, the irregular heartbeat symbol is displayed with the measurement.
If the symbol appears frequently or if it suddenly appears more often than usual, we recommend the patient seek medical advice.
The instrument does not replace a cardiac examina- tion but serves to detect pulse irregularities at an early stage.

Battery change indicator

Batteries almost discharged

When the batteries are approximately 75% used, the battery symbol will flash a few times as soon as the instrument is switched on. Although the instrument will continue to measure reliably, you should obtain replacement batteries.

Batteries discharged – replacements required

When the batteries are discharged, the battery symbol will appear, unblinking, as soon as the instrument is switched on. You cannot take any additional measurements and must replace the batteries.

1. Open the battery compartment on the bottom of the instrument.
2. Replace all of the batteries at the same time, ensure they are correctly connected, as shown on the symbols in the compartment.
3. The memory retains all values although date and time (and possibly also set alarm times) must be reset – the year number will flash automatically after the batteries are replaced.
4. To set a date and time, follow the procedure described in section 3.2.

Note:
Use four new AAA 1.5 V batteries. Do not use batteries beyond their expiration date. If the monitor is not going to be used for a prolonged period, the batteries should be removed.

We do not recommend using rechargeable batteries.

How is blood pressure measured?

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 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).
Blood pressure values must lie within certain normal ranges in order to prevent particular diseases.
Blood pressure is too high if your systolic blood pressure is over 160 mm Hg and/or your diastolic pressure is above 100 mm Hg, 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 mm Hg and 159 mm Hg and/or the diastolic blood pressure values are between 90 mm Hg and 99 mm Hg, consult your physician. Regular self-checks are necessary.
If you have blood pressure values that are too low (i.e., systolic values under 105 mm Hg and/or diastolic values under 60 mm Hg), 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 the 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.

Measurement Guidelines

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

Additional information

• This chart reflects a 2017 update to blood pressure standards.
• 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 doctor.
• Correctly measured diastolic blood pressure values above 120 mm Hg require immediate medical treatment.

What can I do to change my blood pressure?

a) Consult your doctor.
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 constriction caused by deposits in the vessel walls (arteriosclerosis). A deficient supply of blood to important organs (heart, brain, muscles) can result from arteriosclerosis. 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 second- ary hypertension. The latter group can be ascribed to specific organ malfunctions. Please consult your doctor for information about the possible origins of your own increased blood pressure values.
d) There are measures which 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

• Consistently follow all 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. You must receive advice regarding the type and extent of exercise that is appropriate for you.

Care and maintenance

a) The cuff contains a sensitive airtight bubble. Handle this cuff carefully and avoid all types of stress through twisting or buckling.

b) Clean the device with a soft, dry cloth. Do not use gasoline, thinners, or similar solvents. Spots on the cuff can be removed carefully with a damp cloth and soapsuds. Do not wash the cuff in a dishwasher, clothes washer, or submerge it in water.
c) Handle the tube carefully. Do not pull on it. Do not allow the tubing to kink and keep it away from sharp edges.
d) Never open the monitor. This invalidates the manufacturer’s warranty.
