Warning: The R400, R600 and R700 series of presenters are attack vectors and considered harmful. While Heise made an article that detailed that Logitech would exchange the receivers, it did actually not. They sent out a pair of incompatible C-U0014 receivers which could not be paired with R-R0004 presenters and then stopped their program, claiming only to exchange the presenter if it was under warranty, which is a security nightmare (I just tried to get the correct receiver, but Maven M. from Logitech wanted to have the receipt for the module which I obviously do not have anymore). In other words: The hardware is extremely vulnerable, Logitech accepts that it is like that but does not want to get this fixed, so I can only recommend to dispose of the presenter line and do not buy from Logitech anymore. Here is the security write up with the proof of concept to that attack: https://seclists.org/fulldisclosure/2016/Oct/60
To pair an old R400 presenter with a new dongle (or vice versa), try to get the right dongle for your presenter version first:
As stated here, there are two versions of dongles for the presenters - and they are not interchangable:
"There are two versions of presenter receivers that can't be interchanged.
C-U0005
Use the C-U0005 receiver with these presenters:
Wireless Presenter R400 with M/N = R-R0004
Professional Presenter R700 with M/N = R-R0006
Professional Presenter R800 with M/N = R-R0003
C-U0014
Use the C-U0014 receiver with these presenters:
Wireless Presenter R400 with M/N = R-R0008
Professional Presenter R700 with M/N = R-R0010
Professional Presenter R800 with M/N = R-R0009
You can find the model number (M/N) of your presenter inside the battery compartment."
After that, download the Logitech Presenter Connection Software from here (Sorry, only Windows...), start the file and unzip the content.
Update again to this post from 2015 now in 2021: Logitech removed the links from its website, but you still can find the file on its ftp server: ftp://ftp.logitech.com/pub/techsupport/mouse/presenter_connection_zipped.exe ;).
Start the file and unzip the content.
Then, connect your dongle, find the logitech_presenter_connection.exe and start it. After that, the software will ask you to power up your presenter while holding down the to the left and to the right keys of the presenter. 3+ seconds after powering up and holding down the keys, you can release the keys, turn off the presenter again and click Ok in the software. Power on your presenter again and see if it works, if not - try the procedure again.
Update (2019): Had to update the links as they were from 2015 and have changed due to Logitech deciding to changing their design (Thanks Michael!). Also please note the R400, R700 and R800 presenters are considered insecure and the dongles are now replaced by Logitech: https://www.heise.de/security/meldung/Angreifbare-Logitech-Presenter-Hersteller-tauscht-gefaehrliche-USB-Empfaenger-aus-4423627.html
Update (2021): Had to update the download link again, thanks Christopher for asking. But I guess you need to start the software with admin rights (maybe even Win XP, Win 7 "emulation"?), I could not pair my second dongle right now, but the battery is also nearly flat, so that should be an issue.... the software as what I had back then... Maybe it helps some one 🙂
Thank you , awesome repair instructions works great.
Glad it worked for you :)!
Please add the fact that you must Click "Specifications", and then it is the link next to "Software Support". I got a little lost trying to find the right program to install.
Thanks, I updated both links 🙂
Looks like Logitech has removed the software altogether now. There are a number of sketchy looking sites that seem to have it, but I hesitate to download it from a site clearly pretending to be Logitech support...
Yeah, you're right. Never download from such "sources".
Bout you're so in luck, I found the file on Logitechs FTP Server :D!
ftp://ftp.logitech.com/pub/techsupport/mouse/presenter_connection_zipped.exe
(You need to use whatever tool available, probably WinSCP as browser have no ftp support anymore included...)
Cheers

This version from FTP not opens under Windows 10.
But you can open on Logitech site: https://support.logi.com/hc/de/articles/360024692074--Downloads-Wireless-Presenter-R400
There under Downloads you will see nothing. But you should change the Windows Version to Windows 8. You will see the program for Presenter. If you choose "Show all downloads" there will be "Pairing-Funktion für Präsentationsgerät" Program (Don't know how it is in english). This you can run on Windows 10 and pair your presenter and receiver.
Direct link for the program: https://download01.logi.com/web/ftp/pub/techsupport/keyboards/PresenterPairingUtility_1.0.38.exe
Thanks for the infos and direct ftp links, Logitech's support is just terrible.
Totally works! i have 4 extra receivers, wasn't aware of the Part number on the Pointer as well as the receiver (2 of each) - downloaded the pairing (you have to choose more downloads options) - works like a charm! thank you all - gold stars for everyone!!!
For me, it even worked without the software. Pressing up and down while powering on and keeping them down for 3 seconds. Immediately worked after that.
Thanks for reporting back, I really need to get some fresh batteries for my old Logitech controller and try this myself :)!
the windows 10 link worked for me, thanks
@Volodymyr,
Thanks!!! a lot, your last link worked for me in windows 10.
I have several remote controls and receivers - I tried to pair them but without success. I read somewhere that pairing is only possible if the receiver is new (replacement) and has never been paired with any remote control before. Is it true?
Sorry I cannot confirm nor deny that, as I never heard of it.
So theoretically I should be able to pair old receivers (from R400 presenters which i lost) with other R400 presenters (receiver lost) ?
Could work,
but you do need to know which kind of presenter / dongle the lost part was.
C-U0005 receiver only works with M/N = R-R0004 R400 Presenter
C-U0014 receiver only works with M/N = R-R0008 R400 Presenter
So trying to use an R-R0004 Presenter with a C-U0014 receiver will not pair and not work
Other than that, I only got two pairs of these logitech presenters and I discontinued them - the receivers are basically backdoors, without much hardware you can easily use them to attack a computer that has such a receiver plugged in, I can only recommend to throw them away.
