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. Using the device for the first time».
 The measurements stored in the memory are deleted when
the batteries are removed from the battery compartment
(e.g. when replacing batteries).

Safety and protection
 Follow instructions for use. This document provides important
product operation and safety information regarding this device.
Please read this document thoroughly before using the device
and keep for future reference.
 This device may only be used for the purposes described in
these instructions. The manufacturer cannot be held liable for
damage caused by incorrect application.
 This device comprises sensitive components and must be
treated with caution. Observe the storage and operating condi-
tions described in the «Technical specifications» section.
Potential cause and remedy
An adequate pressure cannot
be generated in the cuff. A
leak may have occurred.
Check that the cuff is
correctly connected and is not
too loose. Replace the
batteries if necessary. Repeat
the measurement.
The measuring signals are
inaccurate and no result can
therefore be displayed. Read
through the checklist for
performing reliable measure-
ments and then repeat the
measurement.*
The pressure in the cuff is too
high (over 299 mmHg) OR
the pulse is too high (over 200
beats per minute). Relax for 5
minutes and repeat the
measurement.*
The pulse is too low (less than
40 beats per minute). Repeat
the measurement.*
