I got my HAG Re 4/4 III lok (will post some pictures soon) in the mail this week and I got it set up to run with with my MS2 easy enough. It has a loksound inside. But here is the thing that foxes me - how do I find out what functions it has ? Will post a picture of my MS2 screen if that helps. The MS2 shows me the headlights (F0), then F1 (which appears to be lok operating sounds), F2 and F3 which both appear to be the whistle, F4 has the ABV symbol but seems to be another sound function which I haven't figured out yet. I read in another thread how I have to set up the symbols correctly to get the functions going - but how do I know what functions the lok has . The manuals with the lok mention nothing.

I believe that the Hag Re 4/4 with OEM ESU sound decoder is not different than the Re 4/4II sounds offered by ESU for their decoders.

F1 activates sound
F2 long horn
F3 short horn
F4 accel/braking

There are likely other sounds that can be accessed by F5 to F8. If you have the ESU lokprogrammer, it may be possible to select the Motorola Second Address option, which would allow you to access F5 through F8 by selecting the adjacent address and then F1 through F3. This is useful if you are still using the older 6021. If you have the CS, you should be able to access more sounds directly (maybe also with the MS).
The Hag lok should have come with an ESU Manual. The manual contains general information about the decoder, but not about the particular sounds. According to the esu.eu website, here are the sounds for the Re 4/4II (52742): (F4 was listed as compressor. This function is usually used by Maerklin/Motorola for accel/braking. F5-57 would include the sounds listed, but not necessarily in the order given by ESU.)

Key Function
F0/Function Light off/on
F1 Sound on/off, Fan Sound
F2 Long Horn
F3 Short Horn
F4 Acceleration/brake time, Shuting Mode/Shunting speedcompressor (ESU lists this as F6 and compressor as F4)
F5 pantograph up
F6 compressor
F7 pantograph down

With the Lokprogrammer, individual sounds can be listened to, modified (or replaced)

I replaced the horn on one of my Loksound decoders with a Station Announcement on my Roco Re 460.

Specific questions regarding the decoder can be sent directly to ESU in the USA:

Thanks a ton Mike, that list of functions and the link is super helpful. I do not have a lokprogrammer. No CS or 6021 either, just the 60653 MS2. I think with the info you have provided, I should be able to set things up (phew!).

One of the things I struggle with MMR (and now HAG) is the lack of clear documentation and manuals. Just setting up the functions on the MS2 is such a challenge, even with a manual. Much trial & error. While I enjoy it to an extent as many people on this forum do, I would guess that this is one of the barriers that keeps more people from taking up this hobby beyond their first starter set.

The second address can even be activated with CU 6021 and MS 1.

Since MS 2 supports DCC, there's no need to use the second address - via DCC f0 through f15 are available with one address.
