Keypad Matrix
For maximum flexibility in operation, the HI-3604 has a
keyboard matrix for the upper three keypads on the membrane
switch panel. The function of each of the three keys can be
changed depending on the location of the CURSOR block in the
LCD display. The cursor block is a dark rectangle located at the
bottom edge of the LCD display. On turn on, the cursor is
located above the leftmost of the three columns of functions on
the control panel. In this mode the functions of the three
topmost keys are as follows:
A. SCALE
B. MAX
C. E/H
