Using the A1016 With New Hardware
One of the biggest problems with using older wireless and wired devices is that when you try to use them with newer computers and hardware, you get an incompatibility signal. This is true with older MP3 players and today's modern devices just as it's true with really old games and new gaming systems- if you don't stay current on hardware then you can't keep using your old devices. One of the biggest problems the A1016 has is its seeming incompatibility with the latest craze in touch screens, the iPad.
Using With The iPad
If you're like anyone else out there with one of these Apple wireless keyboard (1st gen), you've probably noticed that- for whatever reason- it won't show up in your iPad's Bluetooth registry. This isn't some sort of one time glitch, however, because Apple has been negligent enough not to update the iPad's firmware, or the keyboard's compatibility (partially due to the fact that it's an old keyboard that they aren't selling anymore). This means that, if you want a wireless keyboard for your iPad, you're going to need to upgrade to one of the newer models.
Using With New Computers (MacBook Pro, Mac Pro, etc)
But what about new Apple computers? Can the old keyboard sync to those? Thankfully, the answer is a resounding "Yes!", though that's not to say people haven't run into issues. Many users report that initially, they had trouble setting up the keyboard because- like the iPad- it didn't seem to show up in the Bluetooth registry. Thankfully, this is fairly easy to fix, and in most cases was the result of a mishap on the users' side.
First, make sure your batteries are fully charged. Many people end up feeling rather silly because they simply forgot to keep the thing fully juiced, and after giving it a few hours to rest, didn't have any more problems.
If this doesn't help you, try making sure Bluetooth is enabled both on your computer and on the keyboard. To do this on the computer end of things (the hard of the two), click the Bluetooth icon in the upper right of your screen and scroll down to activate it by clicking "Turn Bluetooth On". Once done, your device should show up in the list, and if it doesn't, you may need to try a few other things.
