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.

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.
