4. Error Messages / Malfunctions

If an error occurs during a measurement the LCD displays the corresponding error code.
Error Possible Cause
Weak signal or a sudden change in pressure
External disturbance (eg. if there is a cell
phone near by)
Appears when there is an error during the
Abnormal Blood Pressure
In 7D Mode - Protocol was not done correctly
Low battery
If problems occur when using the device the following points should be checked, and if necessary, the
corresponding measures should be taken.
Malfunction
The display remains blank when the device is
switched on.
The pressure does not rise even though the pump is
running.
The device frequently fails to measure the blood
pressure values, or the values measured are too low
or too high.
Every measurement produces varying results
although the instrument functions normally and the
values displayed are normal.
Blood pressure values measured differ from those
measured by the doctor.
Ensure that the cuff is worn correctly and
measure again. Avoid movement or talking
Electromagnetic interferance can cause odd
behaviour in the monitor. Move away from
the source.
Make sure the cuff is wraped around the
arm properly and that the air plug is properly
connected to the unit.
Rest for 5 minutes and try measurement again
Delete all measurements from the memory.
Start Protocol again. Take 4 measurements a
day (2 in the morning, 2 in the evening) for 7
days straight.
Replace batteries.
1. Check batteries for correct polarity.
2. If using the AC adapter, ensure it is correctly
inserted.
Check the connection of the cuff tube and connect
properly, if necessary.
1. Check the positioning of the cuff and cuff tension.
The cuff should be snug but not tight.
2. Measure the blood pressure again, ensuring that
you have remained motionless for a sufficient
amount of time to ensure an accurate reading.
therefore measurements will show some variability.
Record the daily developement of the values and
consult your doctor.
