2.4. High Pot. and Insulating Resistance Tests
At the end of the process, a “High Voltage” and an “Insulating Resistance” tests are required to fulfil Safety
Electrical requirements (CEI 65065).

Insulating Resistance requirements
-
“Voltage”
3500
VAC
-
“Voltage”
500 VDC
-
“Max Leakage Current”
10 mA
-

2.5. SHOP-END Test
At final process stage, it’s necessary to perform “
Reset shop
” before any packing to leave Factory mode and
restore User default presets.
This function is accessible by selecting
“
Factory menu
Reset Shop
”, then pressing RCU “
OK/
►” key. Other
faster methods via UART/IR commands are available on enclosed SIACP requirements (rev. v5.9) .
While USB3.0
as the Serial port,
Reset Shop
also can close the Serial port function, and it is very necessary to perform
“
Reset
shop
”
“ResetShop” presets should follow “
MT5531_EU_OOB_MenuSetting_step1_Base_01.doc
” document.
Note:
A password might be required in case of Parental Control function is locked, use default “
1234
” password
or “
0423
” super password to clean-up existing ones if forgotten.

“
How to upgrade SW FLASH using MTK tool
”
Connect UART interface to suitable manufacturing TV input connector (note that PC connector requires
TVs on “Factory mode”)
Launch MTK tool with version above v0.6.7
Set right SoC template (ex: MT53xx)
