Setup a Bluetooth earpiece (for use with either your cell phone, PDA, or computer) so that it will work with your favorite device. Fortunately, most Bluetooth earpieces are very user friendly, and you should find the process very easy.
Put your Bluetooth-capable device in discovery mode. Most Bluetooth-enabled cell phones, PDAs and computers have a separate Bluetooth utility (generally found in a settings or options area that manages Bluetooth connections). Once you find this utility, look for an icon or link that says, "Find Bluetooth device" or "Enable discovery mode."
Test your connection. If you are using a computer or a phone, the easiest way to do this is to initiate a chat or phone call and see if you can interact with the other party. If you are using your Bluetooth earpiece with a PDA, try performing some basic functions with the earpiece.
