Intended Use

This oscillometric blood pressure monitor is intended for measuring non-invasive blood pressure in people aged 12 years or older. It is clinically validated in patients with hypertension, hypotension, diabetes, pregnancy, pre-eclampsia, atherosclerosis, end-stage renal disease, obesity, and the elderly. The device can detect an irregular pulse suggestive of Atrial Fibrillation (AF). Please note that the device is not intended to diagnose AF. A diagnosis of AF can only be confirmed by ECG. The patient is advised to see a physician.

This device uses the same measuring technology as the award-winning «BP 3BTO-A» model tested according to the British and Irish Hypertension Society (BIHS) protocol.

Preparation for Measurement

1. Sit on a back-supported chair and keep your legs uncrossed.
2. Avoid thick or close-fitting garments on the upper arm.
3. Place the artery mark on the cuff over your artery.
4. Fit the cuff closely, but not too tight.
5. Position the cuff 2-3 cm above your elbow.
6. Keep your arm still and do not speak during the measurement.

Before Each Measurement

• Avoid eating, bathing, smoking, or caffeine intake (approx. 30 min).
• Relax for 5-10 minutes.
• Measure before medication intake.

Using the Device for the First Time

Inserting the Batteries

Open the battery compartment 7, insert 4 new 1.5 V AA alkaline batteries, observing correct polarity.

Setting the Date and Time

1. After battery insertion, the year flashes. Use the M-button 3 to set the year and the MAM button 4 to confirm.
2. Set the month using the M-button, confirm with MAM button, then set the day.
3. Repeat for hour and minutes.
4. Once minutes are set and confirmed, date and time are displayed.
5. To change date/time later, press and hold the MAM button for approx. 3 seconds until the year flashes.

Selecting the Correct Cuff

Microlife offers various cuff sizes. Select a size that matches your upper arm circumference for a close fit.

Pre-shaped cuffs are optionally available. Only use Microlife cuffs. Contact Microlife Service if the enclosed cuff 8 does not fit.

Connect the cuff connector 9 into the cuff socket 5.

Selecting Standard or MAM Mode

Before each measurement, choose between standard (single measurement) or MAM (automatic triple measurement) mode.

• To select MAM mode, press the MAM button 4 until the MAM symbol 15 appears.
• To return to standard mode, press the MAM button again until the symbol disappears.
• In MAM mode, the display shows 1, 2, or 3 for the current measurement.
• There is a 15-second break between measurements, indicated by a countdown.
• Individual results are not displayed; only the final average is shown after all measurements.
• Do not remove the cuff between measurements. A fourth measurement may be taken automatically if one is questionable.
• AF detection is only activated in MAM mode.

Checklist for Taking a Reliable Measurement

• Avoid activity, eating, or smoking immediately before measurement.
• Sit on a back-supported chair and relax for 5 minutes.
• Keep feet flat on the floor and do not cross legs.
• Always measure on the same arm (normally left). Doctors may perform double arm measurements to determine the best arm.
• Remove close-fitting garments. Shirt sleeves should not be rolled up if they are laid flat.
• Ensure the correct cuff size is used.
• Fit the cuff closely but not too tight.
• Position the cuff 2 cm above the elbow.
• The artery mark on the cuff must lie over the brachial artery.
• Support your arm so it is relaxed.
• Ensure the cuff is at the same height as your heart.

Taking a Blood Pressure Measurement

1. Select standard or MAM mode.
2. Press the ON/OFF button 1 to start.
3. The cuff inflates automatically. Relax, do not move or tense your arm muscles. Breathe normally and do not talk.
4. The cuff fit check 18 on the display indicates placement. 18-A means suboptimal fit but measurement can proceed.
5. Pumping stops when correct pressure is reached; pressure falls gradually.
6. The pulse indicator 23 flashes during measurement.
7. Results (systolic 12, diastolic 13, pulse 14) are displayed.
8. Remove the cuff after measurement.
9. Switch off the device (it switches off automatically after approx. 1 min).

AF detection is only activated in MAM mode.

You can stop measurement anytime by pressing the ON/OFF button.

This monitor is tested for use in pregnancy and pre-eclampsia. If high readings occur in pregnancy, re-measure after an hour. If still high, consult a doctor. The AFIB symbol can be ignored in pregnancy.

Manual Inflation

For high systolic pressure (e.g., >135 mmHg), you can set pressure individually. Press ON/OFF after the cuff inflates to ~30 mmHg, keep pressed until ~40 mmHg above expected systolic, then release.

How Not to Store a Reading

Press and hold the ON/OFF button 1 until «M» 16 flashes. Confirm deletion by pressing the MAM button 4. «CL» indicates deletion.

How to Evaluate Your Blood Pressure

The traffic light indicator 22 shows the range:

The higher value determines the evaluation. Example: 140/80 mmHg or 130/90 mmHg indicates «blood pressure too high».

Appearance of the Pulse Arrhythmia (PAD)

The PAD symbol 20 indicates pulse irregularities. Results may deviate; repeat measurement. If the symbol appears regularly, consult your doctor.

Information for the Doctor on Frequent Appearance of the Arrhythmia Indicator

This device detects pulse irregularities. It does not replace a cardiac examination. In MAM mode, AF is also checked. If the symbol appears, select MAM mode and measure again.

Data Memory

The device stores the last 99 measurement values.

Viewing Stored Values

When the device is off, briefly press the M-button 3. It shows «M» 16 and «A» (average). Pressing M again shows previous values.

Readings with suboptimal cuff fit (18-A) are not included in the average.

The memory overwrites the oldest value when full (100th value). Consult a doctor before the memory is full.

Clearing All Values

To permanently remove all stored values, press and hold the M-button (device off) until «CL ALL» appears, then release. Press the MAM button 4 while «CL ALL» flashes to confirm. Individual values cannot be cleared.

Cancel deletion: Press ON/OFF button 1 while «CL ALL» flashes.

Battery Indicator and Battery Change

Low Battery

The battery symbol 17 flashes when batteries are low. The device can still measure reliably, but replacement batteries should be obtained.

Flat Battery - Replacement

The battery symbol 17 flashes when batteries are flat. No further measurements can be taken. Replace batteries.

1. Open battery compartment 7.
2. Replace batteries, observing polarity.
3. Set date and time as described in Section 2. The year number will flash automatically.

Which Batteries and Which Procedure?

Use 4 new, long-life 1.5 V, size AA alkaline batteries. Do not use expired batteries. Remove batteries if the device is not used for a prolonged period.

Using Rechargeable Batteries

Use only «NiMH» type reusable batteries. Batteries must be removed and recharged when the flat battery symbol appears. Do not leave them in the device. Always remove rechargeable batteries if not using the device for a week or more. Batteries cannot be charged in the monitor; use an external charger.

Using a Mains Adapter

The device can be operated with a Microlife mains adapter (DC 6V, 600 mA). Use only the original Microlife adapter. Ensure the adapter and cable are undamaged.

1. Plug the adapter cable into the mains adapter socket 6.
2. Plug the adapter into the wall socket.

No battery current is consumed when the mains adapter is connected.

Error Messages

If an error occurs, the measurement is interrupted and an error message is displayed.

* Please immediately consult your doctor if this or any other problem occurs repeatedly.
