Well as far as the Nintendo Wii problem you have goes, all i know is that the remote control has a reset/ pairing button on the inside near the battery, This will pair the remote device to the Wii console. The console also has a pairing button on it, and this will need to be pressed as far as i know.
Referring to your user manual is probably a good place to start as the manufacturer most certainly is likely to include the instructions on pairing your remote to your console. If however you are prone to mis-placing manuals/ instructions (like i often do) then there is some help on offer here from the boys at http://www.retrevo.com
they have a website for user manuals, so check out the follwing link for stufff related to your gaming console at this link
Now be warned, i did check out the file size for your manual and it is pretty large, so it might be best to avoid using a 56K line to pull your manual down from the FTP server ((you could be better off running down the pub for a few swift pints or 20 of stella artois while you wait for a 56K download in PDF format.
Now once you got your manual, dont forget to open the manual using adobe reader/ adobe acrobat. You get this tool from the internet and going to http://www.google.com
will provide you the option of searching for a free download. Now for some strange reason, if you type the words "adobe reader free download" or "adobe acrobat free download" you will get given a link on where to go for your PDF reader ((wonder how this can be .lol)) and then the download is just a clickie bit away.
Well I hope that this is the fixya for you and please do let me know how you got on with this solution, in addition to this, if you have any further questions please do not hesitate to contact me at earliest opportunity.
