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 the 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 batterries
if necessary. Repeat the measurement.
The measuring signals are inaccurate and
no result can therefore be displayed. Read
through the checklist for performing
reliable measurements and then repeat the
measurement.*
