Frequently Asked Questions:
Q1. Why am I experiencing shorter-than-expected range and / or the audio cutting in and out?
The VIKEFON uses a Class II CSR chipset specified at 20m / 60ft in an OPEN FIELD environment without any walls or floors in the way.
Here are some common causes of short range / unstable audio for the device:
  1. The range depends on BOTH the transmitting and receiving device. Please test your receiving Bluetooth device with a mobile phone to confirm the range is acceptable.
  2. Operation range can be affected by physical obstructions (walls, people, etc.), wireless interference (Wi-Fi routers, Wireless TV adapters, etc).
  3. An UNSTABLE Bluetooth connection can cause range and audio issues. Please reset / clear the pairing history of BOTH DEVICES and re-pair / connect them again.
  4. If you’ve plugged the device into a USB 3.0 port, please change to another (preferably non 3.0) USB port. The USB 3.0 standard has known interference issues with Bluetooth.
  5. Audio issues can be caused by a slow internet connection if you are streaming content (video or music) from an ONLINE source. Please check your internet speed is acceptable.
  6. Unstable power output from the USB port can also cause range and audio issues. If you’re using a desktop computer, please try a USB port on the back of the computer using the extension cable. You can also try using a USB hub with a power adapter.
Q2. How can I stream Music and Talk simultaneously?
The FastStream codec allows both music and talk channels to work simultaneously.
The device supports FastStream and if used together with a FastStream compatible headphone will deliver much better stereo sound while in TALK mode.
Currently there are only a few headphones on the market that support FastStream (though this number is increasing).
Q3. Why can’t I connect the device with my Bluetooth device?
In order to connect, BOTH devices must be in PAIRING mode – please check device manual. Note that turning it “on” doesn’t gaurantee it’s in pairing mode. As a rule of thumb most devices’ LED will flash quickly when it is in pairing mode.
Please check if your Bluetooth device or the device have unintentionally connected to another Bluetooth device instead of each other.
A large amount of wireless interference in the environment can disrupt the pairing process. For example if the device is positioned very close to a WiFi router.
Q4. Why is the device not working / being recognized by my PC ?
Please note the device is a USB audio transmitter. When it is plugged into a PC USB port, it should be recognized as a USB sound card / USB speaker. NO BLUETOOTH icon will appear on the Taskbar. The pairing / connection via Bluetooth is between the device and your headphones / speaker, not the PC.
If you see an “unknown device” indicated in Device manager, please try changing to another computer to test.
