heartbeat, the device may have
difficulty in determining your blood
pressure.
Other
The value is different from
that measured at a clinic
or doctor’s office.
At a clinic or doctor's office
apprehension may cause an elevated
reading. Home measurement reduces
the effects of outside influences
on blood pressure readings,
supplementing the doctor's readings.
––––––––––––
Remove the batteries. Place them back
properly and try the measurement again.
Note: If the actions described above do not solve the problem, contact the dealer. Do not
