The “Remote Control” App Will Not Learn Certain Operations - Sony Xperia Tablet S Help Manual

The "Remote control" app will not learn certain operations.
Your tablet may not be able to learn some remote control operations depending on the kind of IR remote
control. This does not indicate a malfunction.
The IR data port of your tablet may not be facing that of the remote control. Check the position of the IR data
port of your tablet, then try again to match the IR data ports of the tablet and remote control at a distance of
about 20 mm to 50 mm (0.8 in. to 2 in.) [Details].
