I bought the Cinema 7 because it was mentionned on the
back that it could control a 'Grundig'. I have a Grundig TV from Europe.
There is no device code for it in the book. I have been able to teach the remote some basic functions,
but I was wondering if there are pre-set advanced
code for it.

Would appreciate help.

Tks

I will keep you informed if they respond !

Grundig uses an unusual signal, I don't have a match on my files of OFA codes. If I find one I'll let you know.

Technical note:
Grundig uses a bi-phase LSB signal. It appears to have an 8-bit device code sent once and an 8-bit command code which is repeated. The TV signal appears to have a device code of 255 (or possibly 0). IR freq=30.5KHz. Time units = 0010 and 0020 (in hex).

OK, I have an English One For All remote here (URC-7550) and it has 8 device codes for Grundig, but none of them are in the URC-7800.

However, two of them have the same format as the Philips TV code 0054, so give that a try, you might get lucky. Try all the buttons and if you can get any reaction from any button, then you can probably fix the rest with advance codes, but if not, it means that your TV probably uses the European signal and that can't be created in the C7.

I just got an email from the OFA support:

'It seems that your TV uses the european signal, so the code should be 0195...if it doesn't work, it means that your remote does not support your TV.'

I tried code 0195 but it didn't work. The LED doesn't blink twice after I type in the code, it only blinks once. So I think I have to teach my URC-7800 the signals by myself. Very sad !!!!!!!!!!!

Ralf,
One option would be to get an upgradeable remote such as the Producer 8 and have the code added, but these remotes are expensive. However, you can sometimes find deals on eBay, I recently picked up a URC-8080 for $15.

The C7 should have enough learning memory to store somewhere between 24 and 30 commands, which should be more than enough to operate the main functions of your TV. If you have used learning for any other devices, you should probably clear out the remote (using the 980 commands) and then re-program the buttons that you had learned using advanced codes. One unfortunate side effect of having to learn the TV functions is that the volume punch through won't work, so if you want the VCR's volume buttons to work the TV volume (for example) you will have to learn the buttons in the VCR mode too, using up valuable learning memory.
