5.2.3 LCD Contrast control
LCD contrast is controlled by KBC.
Use a function of KBC, A/D converter to measure the temperature with a temperature sensor. Then give
the measured data (10 bits AD value) to the system. According to the value system returns the contrast
data to KBC.
KBC adjusts LCD contrast by contrast data.
LCD contrast diagram is shown in Figure 5.2.3.1.
LCD contrast adjustment is shown in Figure 5.2.3.2.

5.2.4 Backlight Control
Backlight is controlled by KBC.
Measure the amount of light with the light sensor.
When light amount falls below a certain amount backlight turns on. When light amount exceeds a certain
amount backlight turns off.
By having a certain amount of hysteresis it prevents the flickering of the backlight.
Backlight control is shown in Figure 5.2.4.

5.5.2 Power transition
This machine is operated by rechargeable lithium battery (main battery) and coin shaped lithium
battery (backup battery). When the main battery power gets low, battery replacement warning is
displayed. When the main battery becomes more weak that it cannot operate the machine, system
turns the power off automatically. Main RAM and RAM disk memory remains due to the backup
battery. The relation between main battery power and the machine is shown as below.

5.5.4 About power supply
The machine’s power is supplied only from batteries.
When operating the machine while recharging, the machine does not operate from the AC directly
but from the power supplied from the battery that is being recharged.

7. DIAGNOSTIC PROGRAM
7.1 General
Diagnostic program is made for diagnosing the IT-2000 hardware.
This section shows operating instruction of the diagnostic program with using the Flash ROM card.
7.1.1 Install the diagnostic program to Flash ROM card
1 Prepare for Casio Flash ROM card and the diagnostic disk.
2 Copy all files in the diagnostic disk to Flash ROM card.
Diagnostic disk files are listed in 7.1.4.
Note: Casio Flash ROM card is recommended. If used the other card it may not work normally.
7.1.2 Boot operation
1 Set the Flash ROM card to IT-2000.
2 Press the INIT button.
3 Power turn off after the system menu is displayed.
4 Power turn on again.
5 Select “1. use HIMEM”.
6 Press “1” “1” “9” “ ”.
Test menu appears on the display.
Note: Select “2. Not use HIMEM” in operating IrDA test. IrDA test is not able to execute when
HIMEM is in effect.
7.1.3 Execute the each test
1 Select the test number from the menu on the display and press “ ”.
2 Each test is executed.
When the test is complete it returns to the menu. Otherwise error message will be displayed.
3 To get out of the error display press “CLR”.
