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

Error Description
«ERR 1» Signal too
weak
AR
«ERR 2» Error signal
AQ-B
«ERR 3»
Abnormal cuff

Microlife BP B1 Classic
Potential cause and remedy
The pulse signals on the cuff are too
weak. Re-position the cuff and repeat
the measurement.*
During the measurement, error
signals were detected by the cuff,
caused for instance by movement or
muscle tension. Repeat the
measurement, keeping your arm still.
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 neces-
sary. Repeat the measurement.
Error Description
«ERR 5» Abnormal
result
«HI» Pulse or cuff
pressure too
high
«LO» Pulse too low
* Please immediately consult your doctor, if this or any other
