There are a few issues that could cause the BTD300 to have trouble pairing to a device, like hardware issues, driver issues, and interference. Follow the guide below to troubelshoot these issues or help determine the cause of the failure.
Pairing
Double-click the device you’re trying to pair, then wait for Windows to complete the pairing process. Confirm or type any pairing codes, if asked. If you are asked for a pairing code for a device like a headset or speaker, and no pairing code has been provided, use “0000” as the pairing code.
Device Conflicts
There may be additional Bluetooth hardware installed that could conflict with the BTD-300.

Reboot the computer and try to pair a device to it.
Interference Isues
Bluetooth is a low-energy transmission mode, which makes it fairly easy to interfere with or block. If the BTD-300 is plugged into the back of your computer, try moving it to a front or side port. If you are trying to pair to a device that is under your desk or in another room, try pairing to a closer device to see if it can be found. If you have a Wi-Fi router, cordless phone, baby monitor, or any other wireless devices near the BTD-300, try unplugging or moving them while testing, as they can all be major contributors of 2.4Ghz interference.
