2. AGING   
1) Display SERVICE MENU 2. 
2) Select "AGING" with [VOL + ()], [VOL - (↓)] keys.    Press [ENTER] button. 
3) Select “AGING1” or “AGING2” with [VOL + ()] [VOL - ()] buttons, and press [ENTER] button. The aging is started. 
AGING1: Every time when [BRIGHT + ()] button is pressed, the whole screen color is changed. 
 
 
AGING2: The whole screen color is changed every 2 sec. 
 
 
4) When finishing AGING, set this to OFF. 
AGING1 can be directly executed by pressing the [SIZE] button for about 5 seconds (LED flashes and “F” mark is displayed in the upper 
left corner of the screen.) and then pressing the button of [VOL + ()], [VOL - (↓)], [VOL + ()], [VOL - (↓)] sequentially. 
The power button of the remote controller or the machine cannot terminate aging.   
With the A model, the controller is shut down automatically after selecting the AGING.    When the AGING is selected with other input 
screen being displayed, it takes a time to start the AGING.

5. HARDWARE CHECK 
This machine is provided with the function to watch for any abnormality in the hardware. 
*When an error occurs in the hardware (internal power voltage), the message of STATUS [XXXX] is displayed.   
The power lamp flashes in red. (It differs depending on the setting of " STATUS ALERT" of the FUNCTION.) 
*When only a temperature error occurs, the message of "TEMPERATURE" is displayed on the loft lower section of the screen.   
The power lamps of red and green flash alternatively. (It differs depending on the setting of "TEMPERATURE ALERT" of the FUNCTION.) 
*The error position can be checked. There are following four methods. 
 
5 – 1. METHOD1 
1) SERVICE MENU 2 is displayed. 
2) Select "HARDWARE CHECK" with [VOL + ()], [VOL - (↓)] keys, 
and press [ENTER] key. "HARDWARE CHECK" menu is 
displayed. 
 
 
 
 
 
 
 
 
 
3) The watch result and the current measurement value of the     
hardware are displayed. 
Watch result 
"OK" or "NG" is displayed. 
After turning ON the power, if an   
abnormality occurs to be "NG" once, the   
"NG" state is kept until the main power is   
turned OFF. 
Measurement 
value 
The measurement value at the time is 
displayed when HARDWARE CHECK menu 
is displayed.   
The measurement value at the time when 
an abnormality occurred is saved in the log 
data. 
The measurement value of the internal voltage displayed is the 
A/D conversion value.   
The normal range is as shown below.

For more than 99 times, “99” is 
displayed. 
C
Accumulated control time of 
the backlight when a

It takes some time necessary for judgment of a temperature 
abnormality and a hardware abnormality as shown below: 
- Temperature abnormality:                                
Min. 2 minutes (Exceeding the threshold value 3 times 
continuously in the interval of 1 minute). 
- Hardware abnormality:                                  
Min. 18 seconds (Exceeding the threshold value 4 times 
continuously in the interval of 6 seconds).               
Though, therefore, the threshold value is exceeded on the 
“HARDWARE CHECK” screen of SERVICE MANU 2 or in the   
periodic send/ test mail, “OK” may be displayed. 
In addition, when “NG” judgment is made once, “NG” state is 
maintained until the power is turned OFF/ON. Even if, therefore, 
the target value is reduced below the threshold value, the 
judgment may be “NG” with a normal value.
