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.
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 supporting structure, 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 Article 820-40 of the NEC that provides
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 entry 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.

4. Test & Alignment
According to the requirement of order, we suggest take the below steps to finish the appropriate settings.
Note:
All tests and measurements mentioned hereafter have to be carried out at a normal mains voltage
(100 ~ 240 VAC)
All voltages have to be measured with respect to ground, unless otherwise stated
All final tests have to be done on a complete set including LCD panel in a room with temperature of
25+/-7°C
The Picture Performance assessment such as White Balance (luminance and colour temperature)
has to be performed into subdued lighted room after at least 60min of warm-up in order to avoid any
temperature drift influence (colorimetry vs time).
4.1 Pre-Conditions and Power Supply 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 be less than 5%, for example, the voltage for main chip
(+3V3, +2.5V, VDDC1V15, 1V5_DDR, etc.), the voltage for TUNER (TU_3V3), the voltage for amplifier
(AMP_VCC), etc.
4.2 Project ID Modification
There are different ID stored in the EMMC depending on different Panels settings and Models features,
but there’s only one key branching Project ID able to ensure normal display. And when you power on the
TV set, you should make sure the Project ID is accord with the BOM description. If not, you need to
modify the ID. There is two methods to modify the ID:

Change Project ID in Design Menu
In case of “Design mode hotkey” is enabled, press “Back”button to enter Design Menu. To modify
Project ID, you need to go through “Service menuProject ID”, then press Left or Right key to
select suitable ID (Project name is dynamically refreshed). Finally restart the TV set.
In case of “Design mode hotkey” is unabled, you can enter the Design Menu easily with reference
to 3.1 Design Menu.
Change Project ID with RCU
Press “062598”+”Menu”+”XXX” (XXX represents project ID you’d like to switch to) in the remote
control and wait about half an hour, When the set restart automatically, you have successfully
changed project ID.
Here below is none exhaustive ProjectID table for reference:

4.4 LAN/WLAN Test
MAC Address Upgrade
Upgrading MAC address needs to use the tool in factory and through serial command. The specific
method is according to the operation of the factory guidance.
DeviceID (DID) and UserID (UID)
Purpose is to allow Other Network Download (OND) and further specific services over dedicated portal
based on AP.For such, specific DID (32 bytes) and UID (8 bytes) needs to be paired and overwritten into
memory for internal client encryption,as below:
Device ID
User ID
BE4F255BBD106BC8F806AE456350D91F
3546187
Those DID/UID codes can only be set using UART commands following enclosed SIACP requirements
(rev. v3.9).
LAN Test
A rough LAN test can be done by connecting Ethernet to TV’s RJ45 and check that IP, subnet mask, DNS
addresses, which are visible on “HomeSettingsNetwork SettingWired settingsAuto Get IP
Address” (ensure that “Internet Connection” is Enabled at first). More in-depth test can be performed
faster using suitable UART/IR commands following SIACP requirements. SW will internally manage
Network ID (NID) flag controlling all MAC/DID/UID integrity to facilitate PA screening further.
See Appendix 3 “Network Connection”
4.5 SHOP INIT
At final process stage, it’s necessary to perform Shop init before any packing to leave Factory mode and
restore User default presets according to the requirement of order.
This function is accessible by selecting “Factory MenuShop”, then pressing RCU “Right ”or” Left”key.
Other faster methods are available on above enclosed SIACP requirements (rev. v3.9).
