Upper and lower blood pressures and pulse rate are
displayed.
Heart mark flashes when pulse rhythm detected during
measurement was irregular.
2. Press either one of memory buttons, M1 or M2, and the
result is stored in the selected bank.
The selected memory bank number is shown on the display.
The result is stored in the bank selected when the unit is
turned off. When a measurement resulted in an error, it will
not be stored.
3. Press POWER BUTTON to turn off the power.
If you forget to turn off the unit, it will automatically turn off after
3 minutes.
Do not execute repeated measurements. This will cause
engorgement of the wrist and correct values will not be
obtained. Let your wrist rest for at least 5 minutes.
IRREGULAR PULSE RHYTHM INDICATION
Heart mark flashing in measurement result display
indicates irregular pulse rhythm.
Irregular pulse rhythm can be a result of body movement during
measurement or can be because of arrhythmias. Although
frequent appearance of the indication under quiet measurements
may suggest arrhythmias, do not make any judgment on your
own before consulting with your doctor.

AUTOMATIC REPRESSURIZATION
If the pressure applied is judged insufficient in the early phase of
measurement or if movement of the hand or wrist occurs during
measurement, the unit will inflate again to a level about 40
mmHg higher. Automatic Repressurization is repeated until a
measurement is made. However, this does not indicate a problem.
To manually control pressurization, hold down POWER BUTTON
immediately after the start of inflation and release it when the
pressure reaches the level 50 mmHg higher than the expected
maximum systolic pressure. If the pressure value has exceeded
190 mmHg, the inflation will stop when the key is released.
Pressure can be increased to approximately 300 mmHg.
