9. Cleaning and storing the device and cuff

• Clean the device and cuff carefully using a slightly damp
cloth only.
• Do not use any cleaning agents or solvents.
• Under no circumstances hold the device and cuff under wa-
ter, as this can cause liquid to enter and damage the device
and cuff.
• If you store the device and cuff, do not place heavy objects
on the device and cuff. Remove the batteries. The cuff line
should not be bent sharply.

10. Rectifying faults

Error messages can occur when
• measurement error ( appears in the display),
• you move or talk during the measurement (
display),
• the cuff tube is not properly inserted (
• inflation takes longer than 15 seconds (
display),
• the inflation pressure is higher than 300 mmHg (
in the display),
• an error occurs when storing the measured values (
pears in the display),
• exceeding measurement range (
• the data could not be sent to the PC (
display).
In the about cases, you must repeat the measurement. Make
sure that the cuff tube is properly inserted and that you do not
move or talk. Put the batteries back in if necessary, or else
