9. Error messages/troubleshooting
In the event of errors, the error message
EE
appears on the
display.
Error messages may appear if:
• Systolic or diastolic pressure could not be measured (
EE1
)
• The cuff is faulty or fastened too tightly or too loosely (
EE2
)
• The pump pressure is higher than 290 mmHg (
EE8
)
• The data could not be sent via
Bluetooth
®
(
EE7
)
