Adjustment of Data within the NVM memory
To access the NVM memory, press the channel up button on the remote control until the NVM setting is reached. Note that
the NVM address is shown in green and the NVM value is shown in red. Each of the NVM values are stored as a
hexadecimal code, each code comprises of two hexadecimal numbers. Each of these numbers will break down into a four
bit binary code as in the example below.
Hex code                                          A          5
Binary code                                1010               0101
Button on remote to toggle Bit    7654              3210
In the example given above, the hexadecimal code is A5, the binary equivalent is 1010 0101. The remote control button to
toggle each bit on or off (1 or a 0) is shown below the binary code. Therefore to change this  to A6, remote control buttons
1 then 0 would have to be pressed.
Note: In the tables below appear b0, b1, b2,.........,b7, whose indicate the bit number:
         b0 is the Least Significant Bit (LSB).
         b7 is the Most Significant Bit (MSB).
