Technical Alarm Description
The monitor will show ‘HI’ or ‘Lo’ as technical alarm
on LCD with no delay if the determined blood pres-
sure (systolic or diastolic) is outside the rated range
specified in part SPECIFICACIONS. In this case, you
should consult a physician or check if your opera-
tion violated the instructions.
The technical alarm condition (outside the rat-
ed range) is preset in the factory and cannot be
adjusted or inactivated. This alarm condition is
assigned as low priority according to IEC 60601-1-8.
The technical alarm is non-latching and need no
reset. The signal displayed on LCD will disappear
automatically after about 8 seconds.
