Cleaning and storing the device and cuff

To keep your digital blood pressure monitor in the best condition and protect the unit from damage follow the directions listed below:

•Do not use any cleaning agents or solvents.

•Under no circumstances hold the device and cuff under water, as this can cause liquid to enter and damage the device and cuff.

•If you store the device and cuff, do not place heavy objects on the device and cuff. Remove the batteries.

•Clean your device and cuff carefully only with a slightly moistened soft cloth and dry it immediately with a soft dry cloth.

•When storing the device, make sure that no heavy objects are placed on top of it.

•Do not fold the cuff tightly. If the unit is stored near freezing, allow it to acclimate to room temperature before use.

•Always store the unit in its storage case after use.

•This unit may not meet its performance specifications if stored or used outside of the temperature and humidity ranges (see section ‘13. Technical Specifications’).

•Use the unit consistent with the instruction provided in this manual.

Advice on use

•For consistency, always measure your blood pressure at the same time each day.

•Always wait at least 5 minutes between measurements to allow the blood circulation in your arm to return to normal. You may need to increase the wait time depending on your individual physiological characteristics. Because of normal physiologic changes and the many external factors influencing blood pressure, it is unusual to obtain identical blood pressure measurements, even when taken a few minutes apart. Speak with your physician to determine what is affecting your blood pressure and which variation may be seen as normal in your case.

12

•When performing multiple measurements on an individual, wait five minutes between each measurement.

•Do not take a measurement within 30 minutes of eating, drinking, smoking or exercising. You should not be physically tired or exhausted while taking measurement.

•Repeat the measurement if you are unsure of the results.

•Measurements are for your information only

– they are no substitute for a medical examination. Discuss the measurements with your doctor and never base any medical decisions on them (e.g. medicines and their administration).

•Do not use the blood pressure monitor on newborns, pregnant women or patients with pre-ec- lampsia. Consult your doctor before using the blood pressure monitor during pregnancy.

•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.

•For reliable monitoring and reference of blood pressure, keeping long-term records is recommended.

•To minimize measurement variations due to physical activity, rest at least 5 minutes before measuring your blood pressure (or 15 minutes after strenuous activity).

•Stress raises blood pressure.

•Perform measurements in a quiet and relaxed environment at room temperature.

Battery Handling Safety Precautions

•Use only the size and type of batteries specified.

•Be sure to follow the correct polarity when installing the batteries. Reversed batteries may cause damage to the device.

•Do not mix different types of batteries together (e.g. Alkaline and Carbon-zinc or recharge-

13

able batteries) or old batteries with fresh ones. Always replace batteries as a simultaneous set.

•If the batteries in the device are depleted or the device will not be used for a long period of time, remove the batteries to prevent damage or injury from possible battery leakage.

•Do not try to recharge batteries not intended to be recharged; they can overheat and rupture (follow battery manufacturer’s directions).

•Do not dispose of batteries in fire, batteries may explode or leak.

•Clean the battery contacts and also those of the device prior to battery installation.

•Remove discharged batteries from the product and dispose/recycle in compliance with all applicable laws.

•Keep batteries away from children and pets. Batteries may be harmful if swallowed. Should a child or pet swallow a battery, seek medical assistance immediately.

8. Evaluating Results

Irregular Heartbeat:

This device can detect irregular heartbeat patterns during measurement and will indicate them by displaying the irregular heartbeat indicator

.

This may be an indicator for arrhythmia, which is a condition where the heart rhythm is abnormal. These symptoms (omitted or premature heartbeats, slow or excessively fast heart rate) may be caused, among other things, by heart disease, age, physical predisposition, excessive use of stimulants, stress, or lack of sleep. Arrhythmia can only be ascertained through examination by your doctor.

Repeat the measurement if the Irregular Heartbeat Indicator displays after a measurement. Rest for at least five minutes between measurements and

do not talk or move during measurement. If the icon appears often, contact your doctor, since self-diagnosis and treatment based solely on the test results may be dangerous. It is vital to follow your doctor‘s instructions.

9. Classification Categories

Measurements can be classified and assessed by the table below. However, these standard values are only a general guideline, since 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 systolic and dia-

stolic values fall into two different categories, the classification Indicator on the unit always shows the higher category.
