			== Overview - Decoder Lock ==
			The Decoder Lock feature is used to change CVs in only one of several decoders with the same short address ([[CV 1]]) or long address ([[CV 17]] and [[CV 18]]). Typically this becomes a concern only when multiple decoders are installed in the same locomotive. An alternative reason to use Decoder Lock is if you fear that another person may attempt to program your decoder on accident (or on purpose), and you want to prevent that from being possible.

			Fun Fact: The WOWSound Version 5 decoder includes an exclusive new feature which will play an audible warning if you attempt to program a CV while Decoder Lock is active.

			=== To Lock a Decoder: ===

			# Program a number between 1 and 6 into [[CV 16]] in each decoder (see the chart below for the standard values) '''before''' the decoders are installed in the locomotive.
			# Set [[CV 15]] to a value which does not match [[CV 16]], or use a value of 7 to ensure the decoder is locked.
			# The decoders will individually compare [[CV 15]] to [[CV 16]] and, if the values are NOT equal, the CV values of that decoder may NOT be manipulated.

			=== To Unlock a Decoder: ===

			# To change a value in another CV of one of the installed decoders, first write the corresponding number into [[CV 15]] which matches the value in [[CV 16]] for the decoder you wish to program.
			# Set [[CV 15]] to a value which matches the [[CV 16]] value for the decoder you want to program. You may also use a value of 0 in [[CV 15]] if you want to program all of the decoder simultaneously.
			# The decoders will individually compare [[CV 15]] to [[CV 16]] and, if the values are equal, the CV values of that decoder may be manipulated.

			=== Important things to know about decoder lock: ===

			* By default, a DCC decoder will be unlocked, but may or may not have a value set in [[CV 16]]. The Value in [[CV 15]] must be equal to [[CV 16]] in order to read or write CV values.
			* If Decoder Lock is active, only [[CV 15]] and [[CV 16]] can be manipulated. When a decoder is locked, all CV values ''other than'' [[CV 15]] and [[CV 16]] will report "Cannot Read CV" or similar on your Command Station.
			* If the values in [[CV 15]] and [[CV 16]] are different, the decoder is considered locked, and programming request will be ignored.
