4. Oppsett
4.1 Lade øretelefonene
- Connect the micro USB end of the charging cable to the charging port on the inline control module of the earphones.
- Connect the USB-A end of the charging cable to a USB power source (e.g., computer USB port, wall adapter).
- The LED indicator on the control module will illuminate, typically red, during charging.
- Once fully charged (approximately 1-2 hours), the LED indicator will change color (e.g., blue) or turn off.
Merk: Sørg for at øretelefonene er fulladet før første gangs bruk for optimal batterilevetid.
4.2 Bluetooth-paring
- Strøm på: Press and hold the multi-function button (usually the center button on the inline control) for approximately 3-5 seconds until the LED indicator flashes blue and red alternately. This indicates the earphones are in pairing mode.
- Aktiver Bluetooth: Gå til Bluetooth-innstillingene på smarttelefonen eller en annen Bluetooth-aktivert enhet og sørg for at Bluetooth er slått på.
- Søk etter Enheter: Your device will scan for available Bluetooth devices. Look for "KD-904" or a similar name in the list.
- Koble til: Select "KD-904" from the list to initiate the connection. Once successfully paired, the LED indicator on the earphones will typically flash blue slowly or turn solid blue, and you may hear an audible confirmation.
- Koble til på nytt: After initial pairing, the earphones will automatically attempt to connect to the last paired device when powered on, provided the device's Bluetooth is active and within range.
