Q12: Why is there a delay with Bluetooth adapter?

1. It is recommended that the distance is within five meters, please try to be closer to your

computer to see if it is better.

2. Please keep Bluetooth adapter away from the Wi-Fi signal source, because the 2.4GHz Wi-Fi

signal will affect the Bluetooth signal.

3. USB 3.0 introduces radio frequency interference in the 2.4GHz to 2.5GHz range, which is the

same radio spectrum used by Bluetooth and Wi-Fi. Therefore, it is not recommended to use USB

3.0 port, and the Bluetooth adapter should not be too close to your router or working USB 3.0

devices.

Q13: Why my UB400/UB4A cannot find or pair my PS4 PS4TM controller?

For most Bluetooth devices, a computer can find them after UB400/UB4A installed successfully.

But when you want to pair your PC and PS4TM controller, you need to install the extra

application RemotePlayInstaller.exe from Sony. For more detailed content, please refer to the
