measurement which is indicated by two short
beeps.
After the measurement, a small arrow in the
display will indicate if the reading is in the
green, yellow or red range. This device
automatically stores the highest (best) value
to date, with the green range being any
reading above 80% of this best value. A
reading in the yellow range indicates a
reading between 60% and 80% of the best
value. A reading in the red range indicates a
reading below 60% of the best value.
However, these ranges can be set manually
within the software. Please consult your
doctor about the range indication.

measurements sequentially.
9. After each measurement, at first the actual
reading is shown in the display and then it
switches automatic
ally to the highest reading
of your current measurement session. Please
note that the monitor only saves the
highest reading from switching the
device on until switching it off.
