If the earbuds are mounted in the charging case while plugged in, the UVnano process will commence for ten minutes.

Once this process is complete, the charging case's battery status will be displayed.

How to charge

Wired Charging

When the charging cable is connected, the charging status is displayed in the charging case.

NOTE: The earbuds and the charging case are charged at the same time.

Wireless Charging

Align the bottom center of the charging case with the center of the wireless charger.

NOTE: The wireless charger is not provided. HBS-FN4 does not support wireless charging. The wireless charging function may not work in some wireless chargers. Wireless charging feature charges at a slower rate due to less power being transmitted to the charging case.

UVnano Description

UV-C LED process operates for ten minutes and begins when charging case (with earbuds) is plugged in. UV-C LED does not operate while device is charging wirelessly such as on a pad or third party wireless charging device (this only applies to HBS-FN6).

- Independent testing shows the UVnano charging case kills 99.9% of bacteria (Staphylococcus aureus and Escherichia coli) on the speaker mesh of the earbuds in ten minutes while charging. The UV-C LED function works only when the charging case is connected to the power cable.

- For best result, it is recommended that the full 10 minutes of UV-C LED operation be performed while charging.

NOTE: The status indicator light blinks slowly during the UV-C LED operation.

The light will slowly illuminate on and off until the UV-C LED function is complete (10 minutes). Once completed, the indicator light will switch back to the always-on battery indicator, see "Battery Status".

HBS-FN4 does not have a UV-C LED and mood light.

Performance may vary based on usage conditions.

A white product may slightly differ in the color of the UV-C LED contact area, but there is no problem with the product performance.

UV-C LED does not operate while charging wirelessly.

CAUTION: Be aware that the temperature of the earbuds may rise while the UV-C LED is operating.

Avoid direct eye and skin exposure to UV light.

Keep out of reach of children.

Out of Range

If the device connected to the product is out of effective communication range, the communication signal becomes weak and the communication is lost. The effective communication range may vary depending on surrounding and other conditions.

If the device comes back within effective communication range, the product automatically reconnects to the device. If the device is not automatically reconnected, touch the left or right earbud once to connect them.
