Setup
1. Charging the Headset
- Connect the USB charging cable to the charging port on the headset.
- Plug the other end of the USB cable into a compatible USB power source (e.g., computer USB port, USB wall adapter).
- The indicator light will typically show red during charging and turn blue or off when fully charged.
- A full charge takes approximately 2 hours. The headset provides up to 6 hours of battery life for calls/music.
2. Pairing with a Bluetooth Device
- Ensure the headset is fully charged.
- Power On: Press and hold the Multi-function button (usually the main button) on the headset until the indicator light flashes red and blue alternately. This indicates pairing mode.
- Activate Bluetooth: On your smartphone or other Bluetooth device, go to the Bluetooth settings and enable Bluetooth.
- Search for Devices: Your device will scan for available Bluetooth devices. Look for "DEVIA" or a similar name in the list.
- Connect: Select "DEVIA" from the list to pair. Once successfully paired, the indicator light on the headset will usually flash blue slowly or turn off, and you may hear a confirmation tone.
- If prompted for a password, enter "0000" (four zeros).
Note: The headset supports dual-point connection, allowing it to be connected to two Bluetooth devices simultaneously. To use this feature, pair with the first device, then disable Bluetooth on the first device. Put the headset back into pairing mode and pair with the second device.
