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.

1 Confirm that there are 9 screws and a hex keysupplied with the stand unit.

2 Attachthe basbelow.

Setting the TV on the Wall

CAUTION

This TV should be mounted on the wall only with theAN-37AG5 (SHARP) 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. SHARP bears no responsibility forimproper mounting or mounting that results inaccident or injury.

2.3.1 How to upgrade the software1. Unplug the AC cord.

2. Insert the USB memory for version upgrade (prepared as above) into the service socket located Right side from center at terminals, above HDMI4terminal in the rear of the unit.

3. Plug in the AC cord with power button pressed down.

4. After 5 seconds, unpress the power button.

CAUTION: The moment this operation is done, the upgrading of the monitor microprocessor software starts. While the upgrade is ongoing, neverpower off the unit. Otherwise the upgrade will fail and the system may be serious damaged beyond recovery (inability to start).

After the monitor microprocessor software is upgraded, also perform the 'Industry Init'.

LC-32D44U3. Entering and exiting the adjustment process mode1) Before entering the adjustment process mode, the AV position RESET in the video adjustment menu.

2) While holding down the VOL () and INPUT keys at a time, plug in the AC cord of the main unit to turn on the power.

The letter appears on the screen.

3) Next, hold down the VOL () and CH ( ) keys at a time.

(The VOL () and CH ( ) keys should be pressed and held until the display appears.)

Multiple lines of blue characters appearing on the display indicate that the unit is now in the adjustment process mode.

When you fail to enter the adjustment process mode (the display is the same as normal startup), retry the procedure.

4) To exit the adjustment process mode after the adjustment is done, unplug the AC cord from the outlet to make a forced shutdown. (When thepower was turned off with the remote controller, once unplug the AC cord and plug it again. In this case, wait 10 seconds or so before plugging.)

CAUTION: Use due care in handling the information described here lest your users should know how to enter the adjustment process mode. If thesettings are tampered in this mode, unrecoverable system damage may result.
