for as long as the key is held down. This lets you vary the length of time that
the horn or whistle blows, just like the prototype.

#)$ & key operates Function 3 and is labeled with a #)$ & icon to
remind you that this is the preferred function key for coupler operation.
The DCS51 treats Function 3 is a normal on/off function unless you set it up as
a non-latching function like Function 2. This means that F3 can be used either
as a normal function or to control a function that requires a momentary activa-
tion like some couplers.

The DCS51 has a MUTE key that is an alternate to the F8 key that is common-
ly used to mute sound decoders. This key also indicates the current state of
F8/MUTE for the adressed locomotive, and when the indicator light is on, F8 is
ON and a sound decoder will be muted.
Note: Some Sound decoders may use functions other than F8 for mute. In
the case of these decoders, the DSC51 MUTE key will operate F8.
To set up Function 3 as a non-latching function, set the DCS51’s
Option Switch 6 to closed as follows: (or follow instructions of sec-
tion 28)
1. Press the $&# key. The last programming mode used by the
DCS51 will be displayed.
2. Press the '+( key. The display shows the last switch used by
the DCS51.
3. Use the numeric key pad to enter . This tells the system that you
want to change Option Switch 6, the OpSw that controls whether
F3 is latching or non-latching.
4. Press the 1 key to make F3 non-latching. OR Press the A key to
make F3 a normal latching on/off function.
5. Press the Exit key to complete the set up of F3 as a non-latching
key. This will cause the #)$ & key to operate Function 3 as a
non-latching function for this particular DCS51 and any attached
Jump Throttles. Other throttles (including other DCS51s) in the sys-
tem will not be affected.
