Pairing Your Earphones with a Bluetooth Device
Your earphones can be paired with most Bluetooth devices. In order to pair your earphones with
a phone, follow the steps below:
1. Press and hold the “POWER” button until your earphones turn on. The LED indicator light will
start alternately flashing red and then blue repeatedly. This indicates that your earphones are in
pairing mode.
2. Go to the Bluetooth Manager of your Bluetooth device.
3. Search Bluetooth devices and select your earphones (most frequently listed as “ Glow on the
Go”) to start connecting.
4. Enter “0000” if your device asks for the PIN code.
5. Once paired, the LED indicator light will slowly blink blue every few seconds.
Note: If pairing is not completed after an extended period of time, the earphones will power off. If
this happens, repeat the pairing steps above.
Charging Your Earphones
Your earphones have a built-in, rechargeable lithium-polymer battery. To avoid damage, do not
attempt to remove the battery. The full performance of the battery is only achieved after a few
charging-discharging cycles. Charge the battery fully before first use. To do so, follow the steps
below:
1. Connect one end of the included USB charging cable to the charging port on your earphones.
Then plug the other end of the USB charging cable into a USB port on your computer or a
suitable power adapter in order to recharge the internal rechargeable battery.
NOTE: The internal battery of your earphones takes approximately two hours to charge when
completely drained.
2. When the battery is charging, the LED indicator light will turn red. The LED indicator light will
turn blue when the battery is fully charged. Unplug when charging is complete.
NOTE: Overcharging could reduce the life of the battery. A charged battery will lose its capacity if
it is not used on a regular basis.
Important!
To avoid a complete discharge of the battery, charge your earphones at least once every six
months.
