In the cellar, I had an old projector: Sanyo PLC XF 10E, which is an age-old professional device (in this country rather an exotic one). For this device I have no remote control. In this case, that was not a problem: the remote control has found and programmed the correct record right away, that I can now also control the projector again!
If you nevertheless times would allow for special commands, it is of course also possible.
Conclusion: great device, simple operation / programming - all for little money! Now at last it's over with the many remote controls on the coffee table. Even his wife and daughter get along again and are able to switch on the television audio DVD home theater system (via collection command) and to use.
Kudos to Logitech !!
