ADJUSTMENT PROCEDURES

Procedure for turning ON the power
1. Connecting the system
(1) Using the system cable, interconnect the plasma display and the AVC system.
(2) Connect the plasma display to the AC power source.
(3) Connect the AVC System to the AC power source.
2. Procedure for turning ON the power
(1) Turn ON the AC power switch located on the plasma display.
The power indicator on the plasma display will start blinking in red.
(When the AC power switch on the AVC System is not ON, the power indicator on the plasma display always
blinks in red.)
(2) Turn ON the power switch located on the AVC System.
The power indicator on the AVC System will be illuminated in green. Simultaneously, the power indicator on the
plasma display will change from blinking in red to illumination in green. Now the system has started up.
(3) If the power indicators on the AVC System and on the plasma display are both illuminated in red, press the
power key located on the remote controller and the power button located on the plasma display. The power
indicators on the plasma display and on the AVC System will change from red to green. Now the system has
started up.

Procedure for upgrading the AVC System software
(1) With the power being OFF, open the top cabinet of the AVC System and then set the slide switch from the
NORMAL position to the WRITE position by inserting an insulated stick into the cutout located between the
WHITE port on the rear of the shield case for the PC I/F unit and the RS-232C port. (Or the software may be
upgraded by calling the process adjustment mode and using CENTER PROG UPDATE on the process
adjustment menu screen. This is discussed later.)
(2) Connect a program-installed PC to the AVC system using the RS-232C cross cable. (For the details of the
program, see Appendix.)
(3) Open the MS-DOS window on the PC and then go to the directory in which the software is installed.
(4) Start up the system to which the AVC System and plasma display have been connected.
(5) Run “vup.bat (tentative name)” at the MS-DOS prompt. The software will be upgraded.
(6) Load the file “civic_XXXXa.bhx main.bhx osd.bhx (tentative name)”.
It will take a couple of minutes until the file has been loaded. Never turn OFF the power or operate the system
during this rewriting period.
(7) After the file has been loaded, turn OFF the plasma display and the AVC System, and then return the slide
switch in the above step (1) back from the WRITE position to the NORMAL position. Now the software has been
upgraded.

Procedure for adjusting each part of the AVC System
1. The adjustments were made to the best settings at factory. If any setting deviates or if any readjustment is
regarded as necessary when any part has been replaced, perform the following steps.
2. Any parameter that has been changed in the process adjustment mode is stored on the memory. If any
readjustment is required, write down the current value before changing it.
3. Use a stable AC power source.
4. If the program is upgraded, it will take approximately 1 minute for the EEPROM to be initialized before any
video appears. Therefore, you will need to wait for this time period. Do not turn OFF the power or operate the
system during the period.
5. If the program is rewritten, preferably write down the parameters that have been changed within the process
adjustment (see “OSD menu and parameters displayed at manual adjustment”), initialize the EEPROM, and
then reenter the recorded values.
