6. Special features
* STANDBY CAUSE (Page 1/40)
Display of a cause (code) of the last standby
The cause of the last standby is recorded in EEPROM whenever possible.
Checking this code will be useful in finding a problem when you repair the troubled set.
* EEP SAVE (Page 40/40)
Storage of EEP adjustment value
* EEP RECOVER (Page 40/40)
Retrieval of EEP adjustment value from storage area
7. Microcomputer software writing
7.1. Main microcomputer/monitor microcomputer software writing (Main PWB: QPWBXF282WJZZ)
7.2. Model/inch discrimination writing (Main PWB: QPWBXF282WJZZ)
• When writing the sub microcomputer software, the model data is configured with the software from the USB memory mounted to the checker.
• Reference and setting change are enabled through the process menu and RS-232C communication.

<Main PWB>
Software Version Up
File version check
USB memory check
1. Insert a USB memory for the main/monitor microcomputer into the service con-
nector.
2. Supply AC power and write the main software to IC8453 and the monitor micro-
computer software to IC2002.
3. Check that writing is normally completed and turn off the power.
CAUTION: When the USB memory is not inserted or reading error occurs, nothing
is written. (The former models have read the main software from the
writing jig. However, this model reads the main/monitor software from
the USB memory.)
* When IC is failure
Please exchange to another PWB unit when IC8453 (NAND Flash) is failure.
(Because the software can't be written with USB memory, when the new IC is
exchanged from broken IC)

keys on the remote control.
3. Press the Enter key to check that the pattern for adjustment is displayed.
4. Make adjustment so that the flicker located in the center of the screen is mini-
mized using the /- keys on the remote control.
5. If the status is optimized in step 4, press the Enter key to turn off the pattern.
CAUTION: * Make adjustment without ANT signal (since the active backlight
changes the brightness).
