The appearance of the arrhythmia symbol shows that a pulse irregularity corresponding to an irregular heartbeat was detected during the measurement. This is usually not a cause for concern. However, if this symbol appears too frequently, we recommend seeking medical advice. Please note that the device does not replace a cardiac examination, but is only used to detect pulse irregularities at an early stage.

No, the battery of the Geratherm® active control+ is a built-in rechargeable lithium polymer battery. Please do not try to disassemble or force open the blood pressure monitor by yourself or by unauthorized service personnel.

The Geratherm® active control+ cannot be operated with a power pack because it has its own battery.

The measurement can be taken on the left as well as on the right arm. However, further measurements should always be taken on the same arm. Preferably on the arm where the higher blood pressure is to be measured.

Individual blood pressure changes several times a day. It is influenced by a wide variety of factors. Therefore, please make the measurements under the same conditions.

Please do not use this device if you are allergic to polyester, nylon or plastic.

Before using the device by pregnant women, consult a doctor and assess the suitability of the measuring method. In some cases there may be deviations in measurement. Pregnant women are therefore recommended to have regular check measurements carried out by their doctor, since the clinical validation was not carried out with pregnant women.

To clean the case, use a cloth dampened with water or neutral detergent, and then wipe dry. Avoid thinners, petrol and other aggressive cleaning agents.
