9. Cleaning and storing the instrument
• Clean your device and cuff carefully only with a slightly mois-
tened cloth.
• The frequency of cleaning depends on the contamination
level of the device. Clean the blood pressure device and cuff
as soon as any dirt appears on the device.
• Do not use detergents or solvents.
• On no account must you immerse the computer in water,
otherwise liquid can enter it and cause demage.
10. Rectifying faults
Error messages can occur when
• measurement error ( appears in the display),
• you move or talk during the measurement ( appears in the
display),
• the cuff tube is not properly inserted ( appears in the dis-
play),
• inflation takes longer than 15 seconds ( appears in the dis-
play),
• the inflation pressure is higher than 300 mmHg ( appears
in the display),
• an error occurs when storing the measured values ( ap-
pears in the display),
• exceeding measurement range ( appears in the display),
• the data could not be sent to the PC ( appears in the
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
replace them.
