Frequently Asked Questions - Basis Plus Aponorm

How do I set the date and time on my Aponorm Basis Plus?

Press the 'SET' button (usually labeled 'M' or 'Set') to enter setting mode. Use the '+' and '-' buttons to adjust year, month, day, hour, and minute. Confirm each step with the 'SET' button. The device will automatically store the settings.

What does the irregular heartbeat symbol mean?

The irregular heartbeat symbol (e.g., a heart with an arrow) indicates that an irregular heartbeat was detected during measurement. If it appears frequently, consult your doctor. It is not a substitute for a medical diagnosis.

How do I clean the cuff and monitor?

Wipe the monitor with a soft, dry cloth. Do not use any abrasive cleaners or immerse in water. For the cuff, gently clean with a damp cloth and mild soap, then air dry. Never machine wash or dry the cuff.

Can I use the monitor without batteries with an AC adapter?

Yes, the Aponorm Basis Plus can be powered using an optional AC adapter (output: 6V DC, 600mA). Insert the adapter plug into the device's power jack. This may allow you to save batteries.

What should I do if the cuff doesn't fit?

The standard cuff fits arm circumferences of 22–32 cm. If your arm is larger or smaller, purchase a compatible large (32–42 cm) or small (18–22 cm) cuff from Aponorm or an authorized dealer.

How do I interpret the blood pressure classification indicator?

The device displays a colored bar or icon based on WHO classification: Green (optimal), Yellow (normal), Orange (high normal), Red (hypertension). Refer to the manual for exact ranges.

How many readings can be stored in memory?

The device has 2 memory banks (for two users) each storing up to 60 readings, totaling 120 readings. Press the 'M' button to view stored averages or individual readings.

What is the normal blood pressure range according to the device?

According to the WHO classification used, normal blood pressure is systolic <120 mmHg and diastolic <80 mmHg. The device will show a green indicator for this range.

Why does the monitor show an error message 'E1' or 'E2'?

Error E1 indicates inflation failure or loose cuff. Ensure the cuff is properly wrapped and the air plug is securely connected. Error E2 indicates noisy signal or movement; remain still during measurement. Refer to manual for full error codes.

1. Important Facts about Blood Pressure and Self-Measurement

• Blood pressure s the pressure of the blood flowing in the arteries generated by the pumping of the heart. Two values, the systolic (upper) value and the diastolic (lower) value, are always measured.
• The device indicates the pulse rate (the number of times the heart beats in a minute).
  • Permanently high blood pressure values can damage your health and must be treated by your doctor!
• Always discuss your values with your doctor and tell him/her if you have noticed anything unusual or feel unsure. Never rely on single blood pressure readings.
• There are several causes of excessively high blood pressure values. Your doctor will explain them in more detail and offer treatment where appropriate. Besides medication, weight loss and exercise can also lower your blood pressure.
• Under no circumstances should you alter the dosages of any drugs prescribed by your doctor!
• Depending on physical exertion and condition, blood pressure is subject to wide fluctuations as the day progresses. You should therefore take your measurements in the same quiet conditions and when you feel relaxed! Take at least two readings every time (in the morning and in the evening) and average the measurements.
• It is quite normal for two measurements taken in quick succession to produce significantly different results.
• Deviations between measurements taken by your doctor or in the pharmacy and those taken at home are quite normal, as these situations are completely different.
• Several measurements provide much more reliable information about your blood pressure than just one single measurement.

• Leave a small break of at least 15 seconds between two measurements.

• If you suffer from an irregular heartbeat (arrhythmia, see «Section 4.»), measurements taken with this device should be evaluated with your doctor.

• The pulse display is not suitable for checking the frequency of heart pacemakers!
• If you are pregnant, you should monitor your blood pressure very closely as it can change drastically during this time!

This monitor is specially tested for use in pregnancy and preeclampsia. When you detect unusual high readings in pregnancy, you should measure again after 4 hours. If the reading is still too high, consult your doctor or gynaecologist.

How do I evaluate my blood pressure?

Table for classifying home blood pressure values in adults in accordance with the international Guidelines (ESH, AHA, JSH). Data in mmHg.

Range		Systolic	Diastolic	Recommendation
	blood pressure too low	100	60	Consult your doctor
1.	blood pressure optimum	100 - 130	60 - 80	Self-check
2.	blood pressure elevated	130 - 135	80 - 85	Self-check
3.	blood pressure too high	135 - 160	85 - 100	Seek medical advice
4.	blood pressure dangerously high	160	100	Urgently seek medical advice!

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».

2. Using the Device for the First Time

Inserting the batteries

After you have unpacked your device, first insert the batteries. The battery compartment ⑤ is on the bottom of the device. Insert the batteries (4 x size AAA 1,5 V), thereby observing the indicated polarity. Switch the Lock Switch ⑭ to «unlock» position.

Setting the date and time

Your aponorm® Basis Plus upper arm blood pressure monitor is equipped with a radio clock, which is controlled by the DCF77 signal. This time and date are set automatically. If no DCF77 signal (this is the term for the time signal transmitter) is available, the time is not adjusted automatically.

The display comes to receiving mode and device sets the time automatically, after insert batteries.

If you do not wish to set the time or you want to take a measurement immediately, exit the time setting mode by pressing the Start/Stop button ①.

Once the time signal is received, the radio clock icon ② flashes on the display every second until the reception of the DCF77 signal is complete.

While receiving the DCF77 signal, the radio clock icon ② flashes first with 1, then 2 and then 3 bars above it. When the icon appears with 3 bars, the time has been set. First the date and then the time are displayed at the top right of the display. Then the time is displayed permanently together with the radio clock icon ④.

The automatic setting of date and time takes about 2-4 minutes. If no signal is received within 10 minutes, “-” appears on the display.

Now you need to improve the reception by choosing another location or set the clock manually (for more information see „manual setting“). After a change of location, batteries have to be re-inserted or to reset radio clock to „ON“ to restart the auto setting again.

Manual setting

(if automatic setting does not work or is not desired):

The device must be in ON mode. If you do not press any buttons for 1 minute during the time setting, the time setting mode switches off and „-:- -” appears in the clock display.

1. Press down Time button several seconds until „bl OFF“ appears on the display.
2. Press Time button again, the radio clock indicator and "ON" appears in the display.
3. Press the M button to switch on („ON“) or switch off the radio clock („OFF“).
4. Press ON/OFF button to confirm and return to standby mode, or if the radio clock is switched off, you can press Time button to confirm.
5. The year number flashes in the display. You can set the year by pressing either the «+» ⑪ or the «-» ⑩ button. To confirm and then set the month, press the time button ⑧.
6. Press the «+» ⑪ or the «-» ⑩ button to set the month. Press the time button ⑧ to confirm and then set the day.
7. Follow the instructions above to set the day, hour and minutes.
8. Once you have set the minutes and pressed the time button, the date and time are set and the time is displayed.
9. If you want to change the date and time, press and hold the time button down 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

aponorm® by 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).

Cuff size for circumference of upper arm
S 17 - 22 cm
M 22 - 32 cm
M - L 22 - 42 cm
L - XL 32 - 52 cm

Only use aponorm ^® by microlife cuffs.

Connect the cuff to the device by inserting the cuff connector ⑦ into the cuff socket ③ as far as it will go.

3. Taking a Blood Pressure Measurement using this Device

Checklist for taking a reliable measurement

1. Avoid activity, eating or smoking immediately before the measurement.
2. Sit down for at least 5 minutes before the measurement and relax.
3. 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.

4. 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.

5. 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 2 cm above the elbow.
- The artery mark located 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.

1. Slide the lock switch ⑫ down to the «unlock» position. Press the START/STOP button ① to start measuring.

2. 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.

3. When the correct pressure is reached, the pumping stops and the pressure falls gradually. If the required pressure was not reached, the device will automatically pump some more air into the cuff.

4. During the measurement, the pulse indicator ⑳ flashes in the display.

5. The result, comprising the systolic ¹⁴ and the diastolic ¹⁵ blood pressure and the pulse rate ¹⁶ is displayed. Note also the explanations on further display symbols in this booklet.

6. When the device has finished measuring, remove the cuff.

7. Switch off the device. (The monitor does switch off automatically after approx. 1 min.).

How not to store a reading

Press the START/STOP button ① while the reading is being displayed. Keep the button pressed until «M» ⑲ is flashing and then release it. Confirm by pressing the M-button ⑨ again.

You can stop the measurement at any time by pressing the START/STOP button (e.g. if you feel uneasy or an unpleasant pressure sensation).

4. Appearance of the Pulse Arrhythmia Indicator for early Detection

This symbol ② 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 Arrhythmia indicator

This device is an oscillometric blood pressure monitor that also analyses pulse irregularity during measurement. The device is clinically tested.

The arrhythmia 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.

5. Traffic Light Indicator in the Display

The bars on the left-hand edge of the traffic light display ¹⁸ show you the range within which the indicated blood pressure value lies. Depending on the height of the bar, the readout value is either within the optimum (green), elevated (yellow), too high (orange) or dangerously high (red) range. The classification corresponds to the 4 ranges in the table as defined by the international guidelines (ESH, AHA, JSH), as described in «Section 1.».

6. Data Memory

This device automatically stores up to 99 measurement values.

Viewing the stored values

Press the M-button ⑨ briefly, when the device is switched on. The display first shows «M» ⑲ and then an average value. The device then switches to the last stored value.

Press the M-button again to exit the memory mode. Pressing the «+» ⑪ or the «-» ⑩ button repeatedly enables you to move from one stored value to another.

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 values, hold down the M-button ③ until «CL» appears and then release the button.

Press the M-button while «CL» is flashing to permanently clear all values.

Cancel deletion: press START/STOP button ① while «CL» is flashing.

Individual values cannot be cleared.

7. Battery Indicator and Battery change

Low battery

When the batteries are approximately 3/4 empty the battery symbol ⑰ 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 ⑰ 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 ⑤ on the bottom of the device.
2. Replace the batteries – ensure correct polarity as shown by the symbols in the compartment.
3. To set date and time, follow the procedure described in «Section 2».

The memory retains all values although date and time must be reset – the year number therefore flashes automatically after the batteries are replaced.

Which batteries and which procedure?

Use 4 new, long-life 1.5 V, size AAA 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.

Using rechargeable batteries

You can also operate this device using rechargeable batteries.

Only use «NiMH» type reusable batteries.
Batteries must be removed and recharged when the flat battery symbol appears. They should not remain inside the device as they may become damaged (total discharge as a result of low use of the device, even when switched off).
Always remove the rechargeable batteries if you do not intend to use the device for a week or more.
Batteries cannot be charged in the blood pressure monitor. Recharge batteries in an external charger and observe the information regarding charging, care and durability.
