Attaching/Detaching the Stand
Before attaching (or detaching) the stand, unplug the ACcord from the AC INPUT terminal.Before performing work spread cushioning over the basearea to lay the TV on. This will prevent it from beingdamaged.
CAUTION
Attach the stand in the correct direction.Do not remove the stand from the TV unless using anoptional wall mount bracket to mount it.Be sure to follow the instructions. Incorrect installationof the stand may result in the TV falling over.

CAUTION
This TV should be mounted on the wall with boththe AN-37AG2 (SHARP) wall mount bracket and theAN-37P30 (SHARP) attachment of the wall mountbracket. The TV cannot be mounted when withonly the AN-37AG2 wall mount bracket. The use ofother wall mount brackets may result in an unstableinstallation and may cause serious injuries.Installing the TV requires special skill that shouldonly be performed by qualified service personnel.Customers should not attempt to do the workthemselves.

[Adjustment]1) Enter the monitor adjustment process mode.2) Set the specified gradation for standard value 6. Set the strongest
color as the fixed color and adjust RGB by reducing to the standard value.
3) Set the specified gradation for standard value 5. Set the correction value of G [(default of standard value 5) x (G of standard value 6) / (default of standard value 6)] and adjust RB to the standard value.
4) Set the specified gradation for standard value 4. Set the correction value of G [(default of standard value 4) x (G of standard value 6) / (default of standard value 6)] and adjust RB to the standard value.
5) Set the specified gradation for standard value 3. Set the correction value of G [(default of standard value 3) x (G of standard value 6) / (default of standard value 6)] and adjust RB to the standard value.
6) Set the specified gradation for standard value 2. Set the correction value of G [(default of standard value 2) x (G of standard value 6) / (default of standard value 6)] and adjust RB to the standard value.
7) Set the specified gradation for standard value 1. Set the correction value of G [(default of standard value 1) x (G of standard value 6) / (default of standard value 6)] and adjust RB to the standard value.
8) Write the adjustment values with MSET0003 command and turn off AC power.

LC-32/37D64U8.2. Adjusting procedure by use of [RS-232C]1. Get ready the PC with COM port (RS-232C) running on Windows 95/98/ME/2000/XP operating system, as well as the RS-232C cross cable.
2. Start the unit with the RS-232C cable connected.
3. Start the terminal software. (The freeware readily available on the Internet will do.)
4. Make the following settings.
5. If the settings are correct, the terminal software indicates ERR against pressing of the ENTER key.
6. After the settings are done correctly, it is possible to make an adjustment by typing in the command shown in the table below and pressing theENTER key on the keyboard.
7. Command entry is successful if the terminal software indicates OK when the ENTER is pressed. If ERR is shown, retry to enter the command.
8. Send the process mode switching command to switch from the RS232C operation mode to the process mode.
