-The 201776 Backlight/PSU driver can be flashed over the AVR’s ISP programming interface in the following steps:
+<note>Where no shake proof washer is fitted, Thread lock is to be used.</note>
-  - Connect the programming device to a PC with AVR Studio
-  - Connect the AVR Programmer to the ISP interface PL3 of the 201776 board.
-  - Power board up.
-  - In AVR Studio select “Tools” -> “Device Programming”, select the Tool you are using, press “Apply” and check the “Target Voltage” by pressing the “Read” button next to it. If the target voltage is less than 4.7 V, turn the ISP connector to opposite position.
-  - Select the “Fuses” menu from the left panel and set up the following values (see the figure below): <code>
-a.	BOOTLEVEL = 2V7
-b.	Spien = checked
-c.	CKDIV8 = Uncheck
-d.	Bootsz = 4096_7000
-e.	SUT_CKSEL = EXTXOSC_PLLIN_EXTXOSC_16KCK_14CK_64MS (last selection)

-**Programming the main program via ISP:**
-  - Select the main program by clicking on “Memories” menu on the left side.
-  - Push “...” button next to the path of the “Flash (64KB)” file. Choose the hex file, where x is the latest released revision as per : <code>S:\Code\Production\4165 4161 Dual Engine Portrait Display\201578.hex</code>
