We could possibly encounter various kinds of problems when using UB400/UB4A with
Windows PC. This article aims to teach you how to do the troubleshooting.
Q1: Do you have any installation tips to get this Bluetooth adapter works well?
1. UB400/UB4A supports Plug & Play on Windows 10 computer. If not, please download the
driver from the official website and install it manually.
2. DISABLE the built-in Bluetooth before using UB400/UB4A if your computer has the
built-in Bluetooth.(Open Device Manager and right click on the built-in Bluetooth adapter
of your PC and then click Disable device)
3. To properly use UB400/UB4A, please remove all third-party Bluetooth driver or program,
especially CSR harmony software.
Q2: My Bluetooth adapter is successfully installed but I cannot see the Bluetooth icon in
the lower right corner of the Desktop
Please follow the below steps to find the Bluetooth icon.
1. Go to Control panel > Network and Internet > Network and Sharing Center
2. Click on Change Adapter Settings. Then right click on the Bluetooth network > Properties
3. Select the Bluetooth tab, select the Bluetooth Setting, and tick up Show the Bluetooth icon
in the notification area.
4. The Bluetooth icon will be recovered and you can see it in the lower right corner of the
Desktop.
Q3: What if my PC can’t recognize UB400/UB4A when I plug it in? (There is no Bluetooth
Radios symbol in Device Manager)

(1) UB400/UB4A only supports Windows OS. For windows 8 and above system, there is no need
to install Bluetooth driver, but for Windows XP and Windows 7, you need to install the
Bluetooth driver first.
(2) Try to insert UB400/UB4A into a different USB port on your computer. For Windows XP/7,
try to restart the computer after installing the driver. If it still doesn’t work, please try to
uninstall and reinstall the driver.
(3) Make sure there are no other Bluetooth devices on the computer. If there are, disable all existing
Bluetooth devices in Device Manager, then insert the adapter and try again.
(4) Click Computer Management > Services and Applications > Services > Bluetooth support
Service, double-click on the Startup type to change to Automatic, and the service status to
Start.

Q4. There is a Bluetooth Radios in Device Manager, but displays a yellow exclamation point.
Please disable the PC's own Bluetooth adapter and then reinsert UB400/UB4A.
Q5: What can I do if the Bluetooth adapter has a weak signal? How can I improve the
Bluetooth range?
1) Change to another USB port or use a USB extension cable

We see complaints of short-range or cut off often because the adapter is connected to the back of
a desktop computer, where there is a lot of random radio noise generated by the processor and
system parts.
Moving the adapter to the front of the computer often helps, or using a USB 2.0 extension cable
to move the adapter away from the computer.
An Intel white paper also confirmed that poorly shielded USB 3.0 ports will cause radio
interference. If your device is having range issues when plugged into a USB 3.0 port, a USB
extension cable can help with this.
2) Ensure the Bluetooth receiver has a good signal
The Bluetooth range also depends on BOTH the receiving and the transmitting devices. Please
test your receiving Bluetooth device with a mobile phone to confirm its range is acceptable.
3) Eliminate possible interference
Operation range can be affected by physical obstructions (walls, people, etc.), wireless
interference (Wi-Fi routers, Wireless TV adapters, etc.).
4) Stop high traffic applications
If you're watching videos or streaming music from an ONLINE source, please make sure the
audio dropout issue is not caused by slow network speed.
Q6: Why my Bluetooth devices can’t find my PC after UB400/UB4A is installed successfully?
Make sure your PC has enabled the Bluetooth function. Please follow the steps below: right click
on the Bluetooth icon on your PC > Open Settings > More Bluetooth Options
Note: Similar process for the other windows OS.

And then check if Allow Bluetooth devices to find this PC has been selected. This item is
unchecked by default. Only after this item is checked, the phone can find the PC.
Q7: Why my PC can’t find my Bluetooth devices after UB400/UB4A is installed
successfully? / What should I do if there is no search result after I click Search Again after
a search?
1. Make sure your Bluetooth device is set to be discoverable.
2. Please unplug the UB400/UB4A and reinsert it. Or you can also disable it in the Device
Manager and enable it again.
3. The device that was once paired cannot be scanned again unless you delete it. So please try the
following steps on your PC before another scan:

Go to Control Panel > Hardware and Sound > Devices and Printers, and then you will find
the devices that was previously connected to your UB400/UB4A on the Devices page. Right
click on that device and select Remove device. And then try to scan one more time on
UB400/UB4A and you will be able to find the device.
4. For the devices with non-standard Bluetooth protocols, there may be some compatibility
problems. Please refer to Q8 to check out the compatibility list.

problems.

Note: If you are unable to open the service of audio device (e.g. Windows 10), or you cannot
always establish an A2DP connection, please try to delete the current audio device and re-pair it.
Q10: Why is the audio quality so terrible?
Method 1:
1) Go to Control Panel > Devices and Printers.
2) Find your Bluetooth device and if you see an orange alert, go ahead. If not, you can continue
to Method 2.
3) Right click on your device and choose Troubleshoot. Windows will try to fix your problem
Method 2:
1) Go to Control Panel > Devices and Printers.
2) Find your headphone/audio device.
3) Right click on your device and go to Properties.
4) Go to Services tab and uncheck Handsfree Telephony.

5) Hit OK, then restart your machine.
For Windows 7 users:
Go to Control Panel > Hardware and Sound > Manage Audio devices > Right-

Q11: Audio is intermittent when listening to music
Please remove the Bluetooth headphones from devices. (Right click on the Bluetooth symbol in
the lower right corner of the desktop and select Show Bluetooth Devices. And then in
the Audio section, you will find the headphone that has already been connected. Please
click Remove device)
Then re-pair the headphones and add them back as a device. Sometimes you must do this a
couple of times and then the audio starts smoothly playing music and streaming video.

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
