Modern smartphones and tablets should not require a pin code to connect the product, but if they do, use pin code 0000.

As of iOS 11.2, when you are using a Bluetooth headphone and receive a phone call, the button that you use to pick-up the phone call, determines which device is used for the audio.

If you pick-up the phone call with the green button on the iPhone display, then all the audio will be handled by the iPhone microphone and speaker (and not with any connected Bluetooth device).

If you pick-up the phone call with the call pick-up button on the Bluetooth device (headphone or speaker), then all the audio will be handled by the Bluetooth device.

If the person that is calling you cannot hear you – or the other way around – it may be possible that you picked up the phone with one device and are talking via another.

Use the audio icon on the iPhone display during the phone call to change the audio device.

• Make sure the device is set to "findable/pairing mode". Refer to the manual of that device to find out how.
• Make sure the device is located close to your computer.
• Connect like described in the manual of your bluetooth adapter.

Note: some devices like headsets and mice may stay findable for a short time, so connect to them quickly!

• Follow the instructions in the manual carefully.
  • First put the speaker or headphone in pairing mode.
  • Then go to Bluetooth settings on your phone/tablet and select the right name from the list of detected devices.
• If your Bluetooth product is already in the list of Bluetooth devices in your phone, but you still can't connect, remove it from the list and pair it again.
• On Android smartphones you may need to restart your phone after removing the Bluetooth device from the list.

Please follow the installation trouble shooting guide.

• The product in your list of Bluetooth device may be from a physically different product (even though it has the same Bluetooth name).
• Remove the product from the list of connected Bluetooth devices on your phone/tablet/computer and pair it again.
• On Android smartphones you may need to restart your phone after removing the Bluetooth device from the list.

• First check if the volume is not set very low. Check the volume setting on the phone/tablet/computer AND on the speaker/headphone.
• Make sure the speaker/headphone is in the list of Bluetooth devices on your phone/tablet and that the status is shown as 'Connected'.

• Make sure the battery is charged properly. When the battery is almost empty, the sound quality may be affected.
• Make sure the phone/tablet/computer is within range of the Bluetooth product.
  The maximum wireless range is 10 meters, but this will be affected by objects in your surroundings (especially the construction of your house) and the status of the battery.

• Increase the volume on the phone/tablet/computer as well as on the speaker/headphone.
• Note that on computers there can be multiple volume settings, both in Windows as well as in the music player software.
