preparation
installation of batteries in the Remote Control Unit
If the remote control fail to operate TV functions,replace the batteries in the remote control unit
1. Open the battery cover . 2. Inser t two “AA “ size batteries 3. Close the battery cover
(supplied with the product)
.Place the batteries with their terminals
Corresponding to the (+) and (-)
Indications in the battery compartment
CAUTUION
Improper use of batteries can result in chemical leakage or explosion. Be sure to follow the instructions below.
1.Do not mix batteries of different types. Different types of batteries have different characteristics.
2.Do not mix old and new batteries. Mixing old and new batteries can shorten the life of new batteries or cause chemical leakage in old batteries.
3.Remove batteries as soon as they are worn out. Chemicals that leak from batteries that come in contact with skin can cause a rash. If you find
any chemical leakage, wipe thoroughlywith a cloth.
4 The batteries supplied with this product may have a shorter life expectancy due to storage conditions.
5If you will not be using the remote control unit for an extended period of time, remove batteries from it.
using the remote control unit
Use the remote control unit by pointing it towards the
remote control sensor. Objects between the remote control unit and sensor mayprevent proper operation.

Problem
No power
Unit cannot be operated External influence such as lighting ,static electricity,may cause improper
Remote control unit does no operate 1. Is the FUNCTIOn set correctly? Set it to the TV setting position
Picture is cut off/with sidebar screen Are screen mode adjustments such as picture size made correctly?
Strange color,light color,or color misalignment 1. Adjust the picture tone
Powe r is suddenly turned off 1. Is the sleeptimer set?
No picture 1. Is connection to other components correct?
No sound 1. Is the volume too low?
The TV cometimes makes a creacking sound This is not a malfunction.This happens when the cabinet slightly expands
Cautions regarding use in high and low temperature environments
• When the unit is used in a low temperature space (e.g. room, office), the picture may leave trails or appear slightly delayed. This
is not a malfunction, and the unit will recover when the temperature returns to normal.
• Do not leave the unit in a hot or cold location. Also, do not leave the unit in a location exposed to direct sunlight or near a
heater, as this may cause the cabinet to deform and the LCD panel to malfunction.
• Storage temperature: +5°C to +35°C.

compliant.
ECOPACK is an ST trademark. ECOPACK specifications are available at: www.st.com.
I²C uses a two-wire serial interface, comprising a bidirectional data line and a clock line. The devices carry a built-in 4-bit Device Type Identifier code (1010)
in accordance with the I²C bus definition.
The device behaves as a slave in the I²C protocol, with all memory operations synchronized by the serial clock. Read and Write operations are initiated by
a Start condition, generated by the bus master. The Start condition is followed by a device select code and Read/Write bit (RW), terminated by an
acknowledge bit.
When writing data to the memory, the device inserts an acknowledge bit during the 9th bit time, following the bus master’s 8-bit transmission. When data is
read by the bus master, the bus master acknowledges the receipt of the data byte in the same way. Data transfers are terminated by a Stop condition after
an Ack for Write, and after a NoAck for Read
