• Before measuring, stretch your back and sit up straight,
breathe normally 5-6 times, relax your shoulders, arms
and entire body.
• Slightly bend and support your elbow ( e.g. on a table ).
• Do not move, talk or touch the device during measure-
ment.
• Stress influences your blood pressure, so try to relax
before taking a measurement.
• To compare results, measurements must always be
taken from the same arm.
• Do not place the cuff over thick clothes and do not roll up
your sleeve if it is too tight.
• Align the cuff with the height of your heart (breast
height). If necessary use a pillow or cushion.
• Coldness raises your blood pressure. It is recommended
to measure at room temperature ( +20°C).
• Relax before measurement. If necessary go to the
bathroom before measurement.
• Do not measure directly after bathing.
• If you wish to interrupt measurement prematurely, press
the (
) button. Inflation is stopped and the air is auto-
matically released from the cuff.
• If you wish to repeat the measurement, follow the same
procedure as before starting at step 4 (Inflating the cuff).
• Blood pressure measurements taken in a moving vehicle
may be influenced by vibration.
• If an error has occurred during measurement E is dis-
played. Please refer to the next chapter.
• The monitor should be switched off after measurement
to avoid running down the batteries unnecessarily. If you
forget to do so, the monitor switches itself off automati-
cally after 5 minutes.
