Error message/trouble shooting
In the event of errors, the error message _ appears on the display.
Error messages can occur when
1. it was not possible to record the pulse (
),
2. you move or speak during the measurement ( ),
3. the cuff is fastened too tightly or loosely ( ),
4. errors occur during the measurement ( ),
5. the pump pressure is higher than 300 mmHg ( ),
6. the batteries
are almost empty ( ).
In such cases, repeat the measurement. Ensure that you do not move or speak.
If necessary, reinsert or replace the batteries.
Cleaning and storing the unit
• Clean your blood pressure monitor carefully using a slightly damp cloth only.
• Do not use any cleaning agents or solvents.
• Under no circumstances should you hold the unit under water, as this can cause liquid to enter and damage the unit.
• If you store the unit, no heavy objects should be placed on top of it. Remove the batteries. The cuff line should not be
bent sharply.
