I'll try to make a WAV file for you, but we need to know the exact remote you are using. Please use the 983 command to blink back the remote signature. Instructions for non-LCD remotes; probably you can modify these if you have a LCD remote.  If the 983 command doesn't work, please look in the battery compartment.  If the remote is a 9960, we need to know if it is a B00 or B01 version.

Secondly, do you need a WAV file to control the Sky+ or something else?
