4 Step III. Pair your headphones to your device(s) The HX110 is a wireless headphone and needs to be paired to your computer or mobile device before using (see compatibility list for a list of supported devices). Even better, the HX110 is equipped with Bluetooth 4.0, allowing it to be connected to two devices at the same time! To pair the headphones with the first device, 1. Make sure the HX110 is turned OFF. If your headphone is ON (LED light blinking), turn it off by pressing and holding the Multifunction Button (S1) for 5 seconds. 2. Place the HX110 in pairing mode by pressing and holding the Multifunction button for 8 seconds. After 5 seconds, the headphone will turn on and the LED will flash blue. It is important to continue to hold down the button until the LED flashes blue and red rapidly. At this time, the headphone is in pairing mode. 3. On your computer or mobile device, make sure that Bluetooth is turned ON, and that your device is discoverable. 4. On your computer or mobile device, search for available Bluetooth devices. Find and select HX110. Most devices don’t require a password for pairing, but if prompted, enter “0000”. 5. Your device should be paired to the HX110 without any problems. If pairing is unsuccessful, repeat steps 1 - 4. If you are still unsuccessful, contact Alpatronix Customer Service for help. Note: The HX110 is programmed to turn off after 3 minutes of being disconnected from a mobile device. This is a power-saving measure designed to keep your headphone battery from draining in the event that you forget to shut it off before leaving. To pair the HX110 to your second device, repeat steps 1 - 4 with your second device. Once finished, go back to the Bluetooth settings on your first device and manually connect the HX110 from the list of trusted devices. For NFC enabled devices, the HX110 includes NFC function allowing easy and speedy pairing. Make sure the NFC function on your mobile device is on, and touch the headset with your mobile for 5-8 seconds. The LED indicator will flash Red and Blue rapidly to indicate entering into pairing mode, and the headphone will pair with your device after a few seconds. After pairing, the headphone will not need to be paired again. It will search and pair with your device after turning on. To clear the Bluetooth pairing history of your HX110, place the headset into pairing mode at which point the LED will flash blue and red alternately. At this point, press the power button twice. The headphone will emit two beeps to indicate that the pairing history has been successfully emptied.
