The result is stored in the bank selected when the unit
is turned off . Irregular pulse rhythm indication will not be

IRREGULAR PULSE RHYTHM INDICATION
A flashing heart mark in the measurement result
display indicates irregular pulse rhythm. Irregular pulse rhythm can
be a result of body movement during measurement or arrhythmias.
Although continuous appearance of the indication under quiet
measurements may suggest arrhythmias, do not make any
judgment on your own before consulting with your doctor.
Measurement during inflation
Initially the cuff is rapidly pressurized to approximately 25 mmHg at the
beginning of a measurement, during which the inflation mark is
displayed. After the pressure reaches this point, the inflation mark
disappears and the cuff is pressurized more gradually. During this
gradual inflation, pulse is detected and heart mark flashes. Measurement
ends when systolic blood pressure is determined and air is exhausted
from the cuff.
"Personal Mode"
This blood pressure monitor employs what is called "Personal Mode" to
shorten the measurement time and improves comfort. With "Personal
Mode", the pressure to which the monitor rapidly inflates is adjusted
based on the last three measurements. For example, high diastolic blood
pressure values from past three measurements will lead to higher
inflated pressure value than the initial value. In the event that this value is
too high for your current blood pressure, the cuff will rapidly deflate and
measurement will restart.

MEASUREMENT PROCEDURES
Automatic Repressurization
If noise was detected or diastolic
blood pressure suspected to be low,
measurement is interrupted and cuff is
deflated once and inflation starts again.
Do not execute repeated
measurements for congestion
of blood could result in false
measurement. Let your arm
rest for at least 5 minutes.
