Names of Parts and Functions

Charging (Earphones)

Place the earphones into the charging cradle. Charging will begin automatically.

The LED indicator on the earphones shows the charging status:

• Red LED: Charging

The earphone battery level is indicated by 4 levels on the LED.

Ensure the earphones are correctly positioned in the cradle's grooves and check that the earphone LED is illuminated.

Charging (Charging Cradle)

Wired Charging:

1. Insert the USB Type-C cable into the cradle's USB Type-C port.
2. Connect the other end to a power adapter to begin charging.

The charging cradle's battery level will increase from 0% to 100% during charging.

Wireless Charging:

Place the charging cradle on a wireless charging pad (sold separately) to charge it without connecting a cable.

It is recommended to charge the cradle periodically and ensure it is fully charged to 100% for accurate battery readings.

When using wireless charging, place the cradle on the pad and check if the earphone LED lights up.

Charging (Smartphone)

The charging cradle can function as a power bank to charge your smartphone.

1. Insert the USB cable into the cradle's USB Type-A port.
2. Connect the cable to your smartphone.

While charging your smartphone, the cradle's battery level will decrease from 100% to 0%.

Note: The cradle limits the output current to 1.5A. If the cradle's battery level is too low, it may not be possible to charge smartphones that support fast charging.
