10. INITIALIZATION TO FACTORY SETTINGS
Caution: When initialization is performed, all user setting data are initialized. Be cautious when making this adjust-
ment. (The adjustments done in the adjustment process mode are not initialized.)
11. BACKLIGHT USAGE TIME
10-1. GENERAL
In the LB-1085, the backlight usage accumulated time is saved in the machine.
The backlight usage accumulated time is displayed in the item of [BacklightAcutime] (the 6th line on page 2).
When, therefore, the PWB is replaced, perform setting according to the necessity.
Note: If this setting of the backlight usage accumulated time is erroneously performed, the system will falls into a fatal abnormality and it may be per-
manently damaged. Therefore, this setting must be strictly limited only when it is necessary.
10-2. MAIN WPB REPLACEMENT JOBS
1) Read the backlight usage accumulated time (BacklightAcutime) from the monitor before replacement of the main
PWB.
Enter the process adjustment menu, and display page 2, and put down the content of "BacklightAcutime."
*
If the unit does not operate before replacement and reading cannot be made, this procedure is not required.
2) Replace the main PWB, and enter the process adjustment menu.
3) Set the backlight usage accumulated time which was put down in the former procedure. 
(Refer to "10-3. Setting of the backlight usage accumulated time.")
*
If reading cannot be made in the procedure 1), set the backlight usage accumulated time to “0 hour 0 minute.”

ply
Enter the adjustment process mode
Bring the cursor on to [INDUSTRY INIT] , Set to [ON] using [VOL] key, and press [ENTER] key.
• When “INDUSTRY INIT SUCCESS” gets displayed on the green background, it means the procedure
has been successfully carried out. (If an error occurs, “ERROR” is displayed on the red background.)
•  Turn off the AC power.
*
Never shut off the power during the initialization process.
The following settings are initialized by the factory setting.
1) User setting
2) Center Acutime
3) Auto installation flag (When booting after initialization, the initial setting screen appears.)
After the adjustment, cancel the adjustment process mode.
To exit the adjustment process mode, unplug the AC power cable from the outlet to make a forced 
shutdown.
(When the power was turned off with the remote controller, once unplug the power cable and plug it 
again. In this case, wait 10 seconds or so before plugging.)

10-3. SETTING OF THE BACKLIGHT USAGE ACCUMULATED TIME
1) The backlight usage accumulated time which is to be set in the machine is converted into numeric values.
Since setting of the backlight usage accumulated time to the machine is performed for 4 times, four values are
calculated for writing.
2) Enter the process adjustment menu, and display page 34 (for North America) or page 35 (for Europe/China).
3) Write the value converted in the procedure 1) into the machine.
3) - 1. Use SELECT (
/
) key of the machine to shift the cursor to [MONITOR EEP ADR].
3) - 2. Use VOL (+/-) key to set the content of [MONITOR EEP ADR] to [0 x A].
3) - 3. Use SELECT (
/
) key of the machine to shift the cursor to [MONITOR EEP DATA].
3) - 4. Use VOL (+/-) key to set the content of [MONITOR EEP DATA] to the content of [A] in the above procedure 1).
3) - 5. Use SELECT (
/
) key of the machine to shift the cursor to [MONITOR EEP READ/WRITE].
3) - 6. Use VOL (+/-) key to set the content of [MONITOR EEP READ/WRITE] to [WRITE].
3) - 7. Check to confirm that the contents set in 3)-1 to 3)-6 are proper.
If there is any error, repeat the procedures from 3)-1 again.
Caution: Use a special care to confirm that the value of [MONITOR EEP ADR] is set to [0 x A]. If this value is wrong,
the system will fall into an abnormality and it may be permanently damaged.
3) - 8. When all the items are proper, press [ENTER] button.
Writing of the first value is completed with the above procedure.
Write the second value to the fourth value in the same manner.

3)-32. When all the items are proper, press [ENTER] button.
3)-33. Writing of all the values is completed with the above procedure.
4) Display page 2 of the process adjustment menu and check to confirm that the set backlight usage accumulated
time is displayed in the column of [BacklightAcutime].
If the displayed time is not correct, some values converted in the procedure 1) are wrong. Or some operations in
the procedure 3) may be wrong.
Check the contents of the procedures 1) and 3), and set again as needed.
10-4. READING THE SET CONTENT OF THE BACKLIGHT USAGE ACCUMULATED TIME
In the procedure 1) of [10-2. MAIN PWB REPLACEMENT JOBS], the content of "BacklightAcutime" is put down as
the backlight usage accumulated time of the monitor before replacement.
Since, in this model, the backlight usage accumulated time can be read from the machine, if you read the value from
the machine and put it down, there is no need to convert the backlight usage accumulated time into the value for writ-
ing into the machine as described in the procedure 1) of [10-3. SETTING OF THE BACKLIGHT USAGE ACCUMU-
LATED TIME].
The value read from the machine is the value to write into the machine.
Caution: If writing procedure is erroneously performed instead of reading procedure, the time before replacement of
the PWB will be changed. In addition, if the operation is performed erroneously, the system will fall into an
abnormal state and it may be permanently damaged. Therefore, it is advisable to use the setting procedures
of 10-2 and 10-3.
[Reading procedure]
1) Use SELECT (
/
) key of the machine to shift the cursor to [MONITOR EEP READ/WRITE].
2) Use VOL (+/-) key to set the content of [MONITOR EEP READ/WRITE] to [READ].
3) Use SELECT (
/
) key of the machine to shift the cursor to [MONITOR EEP ADR].
4) Use VOL (+/-) key to set the content of [MONITOR EEP ADR] to [0xA].
5) Use SELECT (
/
) key of the machine to shift the cursor to [MONITOR EEP READ/WRITE].
