3.3 SELF-DIAGNOSTIC MODES
The following three self-diagnostic modes are available.
Usually, the test mode is the most convenient for self-diagnosis.
(1) Test mode
The self-diagnostic program in the test mode executes the selected test and
all the subsequent tests.
Note that the following tests involve the use of touch panel operation to start
the tests:
•
LCD pattern test
•
Touch panel test
•
LED/conventional key test
• CMOS RAM test
If it detects a problem, the self-diagnostic system stops executing the test
and displays information about the problem.
