Advice on use

In order to ensure comparable values, always measure your blood pressure at the same time of day.
Before every measurement, relax for about five minutes.
If you want to perform several measurements on the same person, wait five minutes between each measurement.
Do not take a measurement within 30 minutes after eating, drinking, smoking or exercising.
Repeat the measurement if you are unsure of the measured value.
The measurements taken by you are for your information only – they are not a substitute for a medical examination! Discuss the measurements with your doctor, and never base any medical decisions on them (e.g. medicines and their ad- ministration)!
Do not use the blood pressure monitor on newborns, pregnant women or patients with preeclampsia.
In the case of restricted circulation on the arm as a result of chronic or acute vascular diseases (including vascular constriction), the accuracy of the wrist measurement is limited. In this case, you should avoid using an upper arm blood pressure monitor.
This device is not intended for use by people (including children) with restricted physical, sensory or mental skills or a lack of experience and/or a lack of knowledge unless they are supervised by a person who has responsibility for their safety or they receive instructions from this person on how to use the device. Supervise children around the device to ensure they do not play with it.
Cardiovascular diseases may lead to incorrect measurements or have a detrimental effect on measurement accuracy. The same also applies to very low blood pressure, diabetes, circulatory disorders and arrhythmias as well as chills or shaking.
The blood pressure monitor must not be used in connection with a high-frequency surgical unit.
Only use the unit on people who have the specified wrist measurement for the device.
Please note that when inflating, the functions of the limb in question may be impaired.
During the blood pressure measurement, blood circulation must not be stopped for an unnecessarily long time. If the device malfunctions, remove the cuff from the arm.
Do not allow sustained pressure in the cuff or frequent measurements. The resulting restriction of the blood flow may cause injury.
Ensure that the cuff is not placed on an arm in which the arteries or veins are undergoing medical treatment, e.g. intravascular access or therapy, or an arteriovenous (AV) shunt.
Do not use the cuff on people who have undergone a mastectomy.
Do not place the cuff over wounds as this may cause further injury.
Place the cuff on your wrist only. Do not place the cuff on other parts of the body.
The blood pressure monitor can only be operated with batteries.
To conserve the batteries, the monitor switches off automatically if no buttons are pressed for two minutes.

Preparing the measurement

Insert the batteries

Remove the battery compartment lid on the left side of the device.
Insert two 1.5 V micro (alkaline type LR03) batteries.Make sure that the batteries are inserted the correct way round.Do not use rechargeable batteries.
Close the battery compartment lid again carefully.

If the battery change symbol is flashing and appears, no more measurements are possible and you must replace all batteries. After inserting the batteries, the year appears on the display and you can then set the date and time.

Battery disposal

The empty, completely flat batteries must be disposed of through specially designated collection boxes, recycling points or electronics retailers. You are legally required to dispose of the batteries.
The codes below are printed on batteries containing harmful substances:Pb = Battery contains lead,Cd = Battery contains cadmium,Hg = Battery contains mercury.

Setting the date and timeYou should set the date and time without fail. Otherwise, you will not be able to save your measured values correctly with a date and time and access them again later. The time is displayed in the 24-hour format. To set the date and time, proceed as follows:1. After inserting the batteries:

Following the display check, during which all segments appear, the year flashes on the display.
Using the button, you can increase the basic values to be set. Set the year and confirm the entry using the button.
Now set the month using the button. Confirm using the button.
Set the day/hour/minute and confirm each using the button.
To switch off, press the START/STOP button 2. At any time:
Press the button to display the date/time and current user memory.
Press and hold the button again for about 3 seconds to reach Date and time mode.
Set as described above.

Measuring blood pressure Attach the cuff

Expose your left wrist. Ensure that the circulation of the arm is not hindered by tight clothing or similar. Place the cuff on the inside of your wrist.
Fasten the cuff with the hook and loop fastener so that the upper edge of the monitor is positioned approx. 1 cm below the ball of your thumb.
The cuff must be fitted tightly around the wrist, but must not constrict.Adopt the correct posture
Before every measurement, relax for about five minutes. Otherwise, deviations can occur.
You can perform the measurement while sitting or lying. To carry out a blood pressure measurement, make sure you are sitting comfortably with your arms and back leaning on something. Do not cross your legs. Place your feet flat on the ground. Make sure to rest your arm and move it. Always make sure that the cuff is at heart level.Otherwise, significant deviations can occur. Relax your arm and the palm of your hand.
To avoid falsifying the measurement, it is important to remain still during the measurement and not to speak!

Selecting memoryPress the button to display the date/time and current user memory. Select the desired user memory by pressing the user selection button. Confirm your selection with the button. You have 2 memories with 60 memory spaces each to store the measurements of 2 different people separately or to separate measurements taken in the morning and at night.Performing the blood pressure measurement

As described above, attach the cuff and adopt the posture in which you want to perform the measurement.
Select the user memory or. Start the measurement by holding the button. Following the display check, during which all numbers appear, the cuff inflates automatically. Whilst the cuff is pumping up, the device already calculates measurements for estimating the necessary pump pressure.If this pressure is insufficient, the device automatically pumps more pressure.
Then the pressure in the cuff is slowly released and the pulse is detected.
When the measurement has been taken, the remaining air pressure dissipates very quickly. The pulse, systolic, and diastolic blood pressure are displayed.
Measuring can be canceled at any time by pressing.
The symbol appears if the measurement could not be performed properly. Take note of the chapter on error messages/ trouble-shooting in these instructions for use and repeat the measurement.
The device switches off automatically after 2 minutes.Wait at least 5 minutes before taking another measurement!

Evaluating resultsCardiac arrhythmias:This unit can identify potential disruption of the heart rhythm when measuring and if necessary, indicates this after the measurement with the symbol.This can be an indicator of arrhythmia. Arrhythmia is an illness in which the heart rhythm is abnormal because of flaws in the bioelectrical system that regulates the heartbeat. The symptoms (skipped or premature heartbeats, pulse being slow or too fast) can be caused by factors such as heart disease, age, physical make-up, excess stimulants, stress, or lack of sleep. Arrhythmia can only be determined through an examination by your doctor. If the symbol is shown on the display after the measurement has been taken, it should be repeated. Please ensure that you rest for 5 minutes beforehand and do not speak or move during the measurement. If the symbol appears frequently, please consult your doctor. Self-diagnosis and treatment based on the measurements can be dangerous. Always follow your GP’s instructions.

Classification of measurements:The measurements can be classified and evaluated in accordance with the following table.However, these standard values serve only as a general guideline, as the individual blood pressure varies in different people and different age groups, etc.

It is important to consult your doctor regularly for advice. Your doctor will tell you your individual values for normal blood pressure as well as the value above which your blood pressure is classified as dangerous. The classification on the display and the scale on the unit show which category the recorded blood pressure values fall into. If the values of systole and diastole fall into two different categories (e.g. systole in the ‚High normal‘ category and diastole in the ‚Normal‘ category), the graphical classification on the device always shows the higher category; for the example given this would be ‚High normal.

Blood pressurevalue category	Systole(in mmHg)	Diastole(in mmHg)	Action
Setting 3:severe hypertension	≥ 180	≥ 110	seek medical attention
Setting 2:moderate hypertension	160 – 179	100 – 109	seek medical at-tention
Setting 1:mild hypertension	140 – 159	90 – 99	regular monitoringby doctor
High normal	130 – 139	85 – 89	regular monitoringby doctor
Normal	120 – 129	80 – 84	self-monitoring
Optimal	< 120	< 80	self-monitoring
