Irregular heartbeat
This unit has a unique feature that alerts the user if it detects an irregular heartbeat during
measurement.
Note: An irregular heartbeat is defined as a heartbeat rhythm that has a variation of more
than 25% from the average rhythm detected
during measurement.
If such an irregular rhythm occurs twice
or more during the same measurement,
the display will show the pulse value and
the "IH" symbol alternately.
Example: (90 / IH)
Note: Please consult your doctor if an
irregular heart rhythm occurs often.

100 beats per minute during measure-
ment, the unit will display the pulse value
and "LO" symbol alternately. Example:
(58/LO)
Regular but ABOVE normal Heartbeat
If the monitor detects a pulse rate above
100 beats per minute during measurement,
the monitor will display the pulse value and
"HI" symbol alternately. Example: (58/HI)
