Thank you. I did that but it does not work.
I did take apart as I had no choice. It seems there is no contact you are tight but I spent 2 hours doing all sorts of things but the battery compartment is very weird and difficult. Doesn't line up properly

Does the remote’s LED light green?
Else, orange, red or blue, read manual page 18 for how to set it.

And of course it’s covered by your country’s usual warranty.

Ok...I managed to fix it!! I took your advice and cleaned the contact and then slightly bent them enough to make it touch properly.
Thank you everyone but to be honest, the remote does NOT reflect the rest of the unit adequately. Hopefully this will be slightly upgraded to have a better contact.
Cheers

Yeah I have a hard head. Spent the majority of the afternoon changing a battery haha!!

Why shouldn’t it?
This is something with your dealer trying to cop out of responsibility.
Report to RME!

ADI´s remote is in my opinion too not so good.

It has audiophile nervosis -generating EQ, B/T, Loudness and Balance -buttons waiting for accidential presses (and can´t be disabled), its transmit power is mediocre at best, and its general key feel is somewhat crappy.
It uses some rare (NEC?) IR-protocol which some universal remotes may have difficulties to learn. At least my old universal had, it didn´t get ADI´s power command in any way.

Fortunately replacing universal remote to another model worked well, an now ADI is finally under good remote control. I ended up to this model, it learned ADI´s commands, even that power command, without problems

Needless to say, I didn´t teach EQ, B/T, Loudness and Balance -buttons.. Transmit power and key feel is excellent, and ADI responds now in lightning manner.

With this improved remote, general "ADI-usage-experience -index" is now clearly better. Recommend same procedure for everybody having remote issues.

I also had some problems with IR after some months, already discussed here, bad contact on volume keys
.
I replaced it with some programmable universal remote and programmed it and now it is much better than original one. You can program much more functions for you DAC then original one, there is doc with functional codes https://www.rme-audio.de/downloads/adi2 … mmands.zip . You can switch even different setups and filters for immediate comparing.
And reliability is also better. I don't use original IR anymore.

The Remote that is supplied with the ADI-2/4 Pro SE does feel sturdy, even has some weight.

Works nice so far.

Maybe so, it´s typical "TV-remote" -sized, and looks cheap because it IS cheap.
Quite a bargain in my opinion though, I couldn´t believe how good remote controller one can get with 11 €. 8 devices, fully teachable universal remote, with good remote controller general-properties. Using ADI with this new remote is more enjoyable now.

Of course actual main reason to switch universal remote is ability to use multiple devices with the same remote, which I also happened to need.

UPDATE!!
The dealer has sent out a new one for me and I return the original. The original person I talked to was in error about it not being under warranty. It works but still intermittent and it's annoying.
I would like to eventually get an aftermarket one but I would probably lose some functions. Unless someone knows otherwise.

I did not noticed that you have bad link on page https://rme-audio.com/adi-2-dac.html tab Downloads, part Additional downloads, IR commands.
Here you have link http://rme-audio.de/downloads/adi2pro_ir_commands.zip
The same link is on ADI2 Pro page.
So it should be corrected.

I have changed my original post.

I too bought one of these for my ADI2-DAC FS and am really pleased with it. I bought the 4-device version for only £9 in the UK. Currently <£8 - remarkable value for money:

https://www.amazon.co.uk/dp/B077J5YXNH/ … 81_TE_item

It's functionally excellent - ability to learn, ease of use, range, simplicity of batteries. Buttons' tactility is good-enough.

I was fortunate-enough to buy a second-hand Logitech Harmony 300 so that I could get the full set of RME commands. I used the  Logitech to programme the One-For-All - we are fortunate that Logitech's programming software is still available and still works nowadays.

So, I've spent an extra £30 and gone to a load of trouble but now have a good solution to remote-control of my RME.

These remotes like a hard reset every so often. Take the battery out wait a minute, put it back in. If the battery measures 3 volts or above it should work fine.

I have an ADI-2 DAC FS which is working great for 13 months - have even recommended it as an ideal DAC for a regular Hi-Fi setup. However, I cannot say the same about the Remote and the Support that I received. The Remote kept on flashing Green about a week back - and refused to activate any function on the unit. In fact the only function that worked (irrationally) is the Treble change on Line Out which was on active window. I checked in the various forums, and users say this is the death knell for the remote! I changed the battery, but no point.

Sent an email support request to RME - who just sent me their India Dealer's name - who I redirected the support request to - and of course they did not even bother to respond. VERY POOR QUALITY OF SUPPORT RESPONSE. I am not planning to buy another remote as its not very useful and the on-unit controls work very well. But RME is only diluting their brand by using the cheapest remote in the OEM market while promoting a premium engineering product!

Thanks for the suggestion - MC! I just called Ansata (India Disti). They acknowledged receiving my mail along with Invoice and complaint - and now they sent a response mail. They will look into it and confirm resolution, if any.

UPDATE 09OCT23: The support engineer from Ansata (India Disti) interacted with me over phone and email. His intents were honorable and he tried his best - but his repertoire was limited to asking me to RESET the DAC (did it twice) and Change battery (already done). The condition did not improve at all as the green LED keeps blinking and then dies, without any action on the DAC. Finally he informed that RME has responded that the equipment is out of warranty (as I had mentioned earlier, its 13 months old), and that the faulty Remote needs to be shipped back to RME HK for repair. The cost of postage is not worth it to ship from India to HK. Also, that I could buy a New Remote for INR 1900 (23 Euro). This was a no-brainer resolution and frankly the remote is not worth even that amount. So a waste of 1 month of useless communication. As MC had suggested, I am sending the above content to RME Support by email as well. My take remains as earlier - a very good piece of audiophile grade equipment being saddled with a cheap remote. So those who are shy of using the unit controls - and overly dependent on remotes - should think twice!!

If it hasn´t need to be special-fancy i.e. without touchscreen/bluetooth/wlan/home automation integration does, my recommendation is still One For All Contour 8.

https://www.amazon.de/-/en/One-Contour- … 1&th=1

Excellent basic IR-remote. Learns ADI´s original remote without problems.

There is (not unreasonably) no working preset codes for this special professional device like ADI-2. Its commands must be teached manually, key by key, from ADI´s original remote.

The manual of One for All tells procedure to be like this:

To learn, firstly make sure you have all your original remote controls to hand, and that they
have working batteries in. To learn functions, the original remote should be
approximately 3cm from the OFA remote, pointing towards it...

1. Hold down MAGIC until the LED under the device blinks twice. The LED
under the current mode will stay lit.
2. Using the DEVICES key, make sure the LED for the device you want to learn
functions on is lit.
3. Press 975 – the LED will blink twice.
4. Press and release the key you want to learn a function onto (for example
the FAV key) – The Watch TV and Listen To Music LEDs will light up.
5. Press and release the key on the original remote.
6. The LED under the device will blink twice to indicate the key has been learned correctly.
7. Repeat steps 4 and 5 for each key you want to learn – remember you can learn from multiple
remotes, but only one function per key.
8. When you have learned all the functions you require, press and hold the
MAGIC key until the LED blinks twice and turns off

As you see, the model I praised before and wrote about, was different: Contour 8 (URC1280), a plain basic model. Model you have, is more advanced, but also more error prone and complicated, model Smart Control 5 (URC7955).

I didn´t have anything specialities, neither difficulties, during process of learning with my Contour 8. Everything went exactly like instructions told and intuition guided.

ADI´s power button was learnt same way as other buttons. It doesn´t need to be pressed differently (long or short) during learning. ADI recognises (and acts accordingly) its pressing duration automatically when pressed in use.

My suspection is, your units advanced Activities-, Macro- or automatic App -setup over bluetooth -functions may have gone haywire or totally mixed-up from several preset codes and/or learning attempts you have tried to enter. On who-knows-which -mode...  

So I would suggest to do a complete reset for your remote, and try from beginning from clean slate and keeping things as simple as possible this time: no preset codes, no Macros, no Activities, no automatic App -setup. But only manual learning of ADI´s buttons, pressing them physically with fingers.

OFA instructs to do complete factory reset like this:

1. Hold the MAGIC key down until the LED blinks once and then twice.
2. Enter code 981 the LED will blink four times in total.

You can now setup your remote again.

https://www.oneforall.com/en-gb/support … rt-control

If problems still persist, your Smart Control 5 -unit is quite probably defective and needs to be replaced. These are not lab grade -quality controlled devices after all...

Does learning process of power button complete OK like instructions describe?

Buttons of One for All remotes may have (undocumented) limitations what they can learn. Try teaching ADI´s power button to where it is "intended" to be, the Contour 8´s red power button. This way I have it, and it works.     

You could also swap battery (CR2025) of ADI´s remote to fresh one. Weak ir-signals sent by weak battery could result weird problems in learning process; maybe ADI itself could still interpret them OK and work with them, but universal remote´s learning process not, failing to learn it right.   

ADI´s power button has something unusual in it, evidently a tricky one to deal with for universal remotes. My previous universal didn´t got it, and that´s why I replaced it with this OFA Contour 8 at first place.

Edit will make a new thread

Good to know. Yeah I did search for a Harmony but they're just too difficult to find now apparently. This contour remote will have to do I guess.
