(3) Release the switch when the display shown below appears.
* Operation is not guaranteed if the switch is released before the display appears.
(4) Enter 99990000 and then [OK].
(5) LCD calibration test starts automatically.
Refer to [ 12 ] LCD calibration test for the operation details.
7-2. Notes for the DIAG
•Make sure the printer used to print out test results is set to a baud rate of 9600 bps and is connected
to COM4.
•Perform testing by connecting HHS-15 to COM2.
•Always make sure to connect REMOTE DISP to COM3.
•When desiring to conduct a test for an unlimited number of times, enter a value other than 0 in
accordance with the explanation for each test.  Tests are performed for an unlimited number of times
when a value of 1 through 9 is entered for the commend used to specify the number of times testing
is performed in the operating procedure on each page.  However, this function allows a test to only
be performed once or for an unlimited number times.
[Procedure and Display for Operator-Evaluated Tests]
•In operator-evaluated tests, the results for that test are determined according to the OK and NG keys
after the following display appears.
[OK] key: Register 1   [NG] key: Register 9
•A display that excludes the following display is shown for the LCD display of each test.
| Please Hit Key  OK-> 1  NG-> 9  |
[Other]
* ESC printout and display contents for forced termination of a test by ESC are as shown below.  This
display and printout are omitted in each test.
