2. Attach the lithium battery in the reverse order of steps.

1-9. Warning on Power Connection

Boards requiring use of unleaded solder are printed with a lead free mark (LF) indicating the solder contains no lead. (Caution: Some printed circuit boards may not come printed with the lead free mark due to their particular size.)
: LEAD FREE MARK
m . Be sure to use the unleaded solder for the printed circuit
board printed with the lead free mark.
. The unleaded solder melts at a temperature about 40 dC
higher than the ordinary solder, therefore, it is recom­mended to use the soldering iron having a temperature regulator.
. The ordinary soldering iron can be used but the iron tip
has to be applied to the solder joint for a slightly longer time. The printed pattern (copper foil) may peel away if the heated tip is applied for too long, so be careful.
Use the proper power cord for your local power supply.

1. EEPROM Initialize
EEPROM Configuration
Table 1 (page 2-13) shows the configuration of EEPROM. The entire area or the respective areas of the EEPROM can be separately initialized.
Menu Structure
Select the desired area of EEPROM to be initialized using the following menu.
Service Mode EEPROM Initialize
Whole Area Common White Balance Prog. Gamma Prog. Preset Last Memory User Memory Factory
To initialize the desired area, firstly select the desired item from the EEPROM RESET menu. Change the selected item from “CANCEL” to “OK”. Then press “ENTER”.
a) Whole Area
It initializes whole area of EEPROM. This command is identical to carrying out the all items of Common, White Balance, Prog. Gamma,
“Prog. Preset”, “Last Memory”, “User Memory” and “Factory”.
Execute this command only when the memory (IC1007) on the B board is replaced.
b) Common
It initializes Common (1)”, “Common (2) and Common (3) of the COMMON DATA AREA shown in Table 1. It initializes the data unique to the machine and the common data (various setup values of the user menu). Do not carry out this command because it initializes the serial number and accumulative operation hours.
c) White Balance
It initializes Color Temp (1) and Color Temp (2) of the COMMON DATA AREA shown in Table 1. It initializes the color temperature “High”, “Mid” and Low, and all data of user setup 1 to 3 to 00. It also initializes the user name to User1, User2 and User3.
d) Prog. Gamma
This command is not used in this machine.
e) Prog. Preset
It initializes the PRESET DATA AREA (page 2-13) shown in Table 1. It resets the backup preset area.
f) Last Memory
It initializes LAST MEMORY AREA (pages 2-13,
14) shown in Table 1. It initializes the last memory data that user has adjust­ed for each signal.
g) User Memory
This command is not used in this machine.
h) Factory
It resets the EEPROM to the factory default status. All of the EEPROM areas except the following are initialized by this command.

Editing procedure
An independent memory area (editing RAM) is assigned for data editing inside the system controller as shown below. First, copy the source data for editing to the editing RAM. Then modify the data on the editing RAM and save the editing contents to the specified preset area of EEPROM. In addition to the default preset data that has been set already when shipped from the factory, you can edit the various data from the already saved data in EEPROM or the signal data that is being input at this moment. (The following example shows the case the data stored in the EEPROM preset area No.2 is used for editing and the edited data is stored in the area No.11.)

It enables or disables the dot adjustment in the user menu. ON : The dot adjustment is enabled in the user
menu.
OFF : The dot adjustment is disabled in the user
menu. If the actual input signal specification is different from the setups of H. Total Pixel and H. Active Pixel due to fetching the interlace, set this item to OFF.
4 Frame synchronization setting
It sets synchronization setting of the picture input to scan converter. ON : Vertical sync of PDP panel synchronizes with
the input signal. OFF : The PDP panel display signal is no more
synchronized with the input signal. When the
