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.

Button on remote to toggle Bit
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.
