IMPORTANT SAFETY INSTRUCTIONS

CAUTION:

Read all of these instructions. Sa ve these instructions for later use . Follo w all Warnings and Instructions marked on the audio equipment.

1. Read Instructions-All the safety and operating instructionsshouldbe read before the productis operated.

2. Retain Instructions- The safety and operating instructions should be retained for future reference.

3. Heed Warnings- All warnings on the product and in the operating instructions should be adhered to.

4. Follow Instructions- All operating and use instructions should be followed.

FOR YOUR PERSONAL SAFETY

1. When the power cord or plugis damaged or frayed, unplug this television set from the wall outlet and refer servicing to qualified service personnel.

2. Do not overload wall outlets and extension cords as this can result in fire or electric shock.

3. Do not allow anything to rest on or roll over the power cord, and do not place the TV where power cord is subject to traffic or abuse. This may result in a shock or fire hazard.

4. Do not attempt to service this television set yourself as opening or removing covers may expose you to dangerous voltage or other hazards. Refer all servicing to qualified service personnel.

5. Never push objects of any kind into this television set through cabinet slots as they may touch dangerous voltage points or short out parts that could result in a fire or electric shock. Never spill liquid of any kind on the television set.

6. If the television set has been dropped or the cabinet has been damaged, unplug this television set from the wall outlet and refer servicing to qualified service personnel.

7. If liquid has been spilled into the television set, unplug this television set from the wall outlet and refer ser vicing to qualified service personnel.

8. Do not subject your television set to impact of any kind. Be particularly careful not to damage the picture tube surface.

9. Unplug this television set from the wall outlet before cleaning. Do not use liquid cleaners or aerosol cleaners. Use a damp cloth for cleaning.

10.1. Do not place this television set on an unstable cart, stand, or table. The television set may fall, causing serious injury to a child or an adult, and serious damage to the appliance. Use only with a car t or stand recommended by the manufacturer, or sold with the television set. Wall or shelf mounting should follow the manufacturer s instructions, and should use a mounting kit approved by the manufacturer.

10.2. An appliance and cart combination should be moved with care. Quick stops, excessive force, and uneven surfaces may cause the appliance and cart combination to overturn.

SCHNEIDER ELECTRONICS GMBH-GERMANY

PROTECTION AND LOCATION OF YOUR SET

Do not use this television set near water ... for example, near a bathtub, washbowl, kitchen sink, or laundry tub, in a wet basement, or near a swimming pool, etc. Never expose the set to rain or water. If the set has been exposed to rain or water, unplug the set from the wall outlet and refer servicing to qualified service personnel.

12. Choose a place where light (artificial or sunlight) does not shine directly on the screen.

13. Avoid dusty places, since piling up of dust inside TV chassis may cause failure of the set when high humidity persists.

14. The set has slots, or openings in the cabinet for ventilation purposes, to provide reliable operation of the receiver, to

protect it from overheating. These openings must not be blocked or covered.

Never cover the slots or openings with cloth or other material. Never block the bottom ventilation slots of the set by placing it on a bed, sofa, rug, etc. Never place the set near or over a radiator or heat register. Never place the set in enclosure, unless proper ventilation is provided.

PROTECTION AND LOCATION OF YOUR SET

15.1. If an outside antenna is connected to the television set, be sure the antenna system is grounded so as to provide some

protection against voltage surges and built up static charges, Section 810 of the National Electrical Code, NFPA No. 70-1975, provides information with respect to proper grounding of the mast and supportingstructure, grounding of the lead-in wire to an antenna discharge unit, size of grounding conductors, location of antenna discharge unit, connection to grounding electrode, and requirements for the grounding electrode.

15.2. Note to CATV system installer : (Only for the television set with CATV reception)

This reminder is provided to call the CATV system attention to Ar ticle 820-40 of the NEC that provides

installer s guidelines for proper grounding and, in particular, specifies that the cable ground shall be connected to the grounding system of the building, as close to the point of cable entr y as practical.

16. An outside antenna system should not be located in the vicinity of overhead power lines or other electric lights or power circuits, or where it can fall into such power lines or circuits. When installing an outside antenna system, extreme care should be taken to keep from touching such power lines or circuits as contact with them might be fatal.

17. For added protection for this television set during a lightning storm, or when it is left unattended and unused for long periods of time, unplug it from the wall outlet and disconnect the antenna. This will prevent damage due to lightning and power-line surges.

SCHNEIDER ELECTRONICS GMBH-GERMANY

1. PCB/SKD Assembly: Test & Alignment

1.1. Pre-Conditions and DC/DC Check

Before power-on, please check the board according to the relevant block diagram and circuit diagram, and make sure that no serious issue or mistake can destroy the board. For example, the output of DC/DC and LDO should not be shorted to ground.

Supply a suited voltage and power-on, then check the voltage according to the relevant block diagram, circuit diagram and voltage spec. The error should less than 5%. For example, the voltage for main chip (+3V3, AV3.3, +1V2, CORE1V, etc.), the voltage for DDR (DDRV), the voltage for amplifier (AMP_VCC), etc...

1.3. Project ID Modification

There are different ID stored into the NVM depending on different Panels settings and Models features, but there’s only one key branching Project ID that includes all. So, it’s not recommended to modify Panel ID with Hyper terminal as other ID features may not change!

To modify Project ID, you need to go through “Design menuService menuProject ID”, then spin left or right with RCU “Zoom±” keys to suitable ID (Project name is dynamically refreshed).

See Appendix

Picture video formats can be changed by the factory according to their own standard.

Remark：1. AV Video & Audio in shared with CMP.

1.5. AD Calibration Test

As SoC is built-in an A/D self-calibration mechanism, ADC need not to be performed any more.

1.6. DDC & EDID & T-Link Test

The E-EDID data structures are according to VESA Enhanced EDID 1.3 (and EIA/CEA-861B for

HDMI). CEA Timing Extension structure has been extended to support all 3D capable timings.

All VGA and HDMI structures have their own BIN profile which are part of main SW and uploaded

at power-on into HDMI switch chipset.

For EDID check, it’s needed to check whether the correct EDID is downloaded by checking corresponding EDID NVM Checksum or read them out to check bit by bit if it is in line with the released EDID bin file.

1.7. HDCP Test

Page 5 of 9

Factory Test & Alignment Specification For MS68A-AP Series (V1.0).Doc

For HDCP compliancy, it’s needed to check whether the HDCP key has been well set.

2.2. Warm-up

Following TCL standard and practices, it’s required minimum 15min of Warm-Up that can be considered as Burn-In. Additional Aging for White Balance alignment is no more necessary due to consistent Picture Performance with Cloning usage. This function is accessible by selecting “Factory menu WARM-UP”, pressing RCU “Zoom+” key and then leaving Factory menu. Other faster methods are available on above enclosed SIACP requirements (rev. v3.9).
