VII. FRONT AND REAR PANEL CONTROLS
FRONT PANEL
The front panel of the IC22/IC22XT series shown above has a tactile touch membrane
keyboard with an audible feedback button press beep. The keyboard is used to set all
operating parameters. The display is a two-line alphanumeric LCD with backlighting. When
the unit is turned on the display will light and show the Set Point(“sp”) and Plate Temp.(“T”)
for both the front (“F”) and back (“B”) plates. Each set point temperature is set by pressing
the up arrow button to increment the value, and the down arrow button to decrement the
value. The arrow cursor on the display indicates which plate is selected. Pressing both up
and down arrow buttons at the same time will toggle the cursor between the front and back
plates. The displayed plate temperatures are the actual temperature of the center of the
plate surface. There are two LEDs on the front panel. One is a power-on indicator and the
other is the plate surface hot indicator that will illuminate when the plate is at or above 50C.
