Before you start using the earphones, you must charge the battery and pair the earphones with a compatible device.

Charging the earphones and charging case

The BH406 charging case has an internal, rechargeable battery that must be fully charged before being used for the first time. It takes about 2 hours to fully charge the battery for the first time. If you do not use the device for a long period of time, please charge it once every 2 months to avoid damage to the battery.

• Put the earphones in the charging case and close the cover to charge. During charging, the indicators will show a steady red colour. When the battery is fully charged, the red light will turn off.
  
• You can charge the charging case by using the wall charger, car charger or micro USB charging cable. When the charging case is fully charged, all four LED lights will turn solid white.
• Battery status of the charging case: click on this button on the charging case and you will see the battery status, as indicated by the four white LEDs. The LEDs will turn off automatically after 4 seconds.
  

	LED light	Battery level
	1	0~25%
	1.2	25~50%
	1.2.3	50~75%
	1.2.3.4	75~100%

Fully charged earphone batteries have the power for up to 2 hours of talk time (4 hours more from a portable charger). When the batteries are running out of power, the red indicator light will start to flash every 20 seconds on both earphones. This indicates that the earphones need to be charged as soon as possible.

Tips for TWS pairing

TWS pairing is a technical term for using the Bluetooth product. Make two Bluetooth enable devices to be in wireless connection. The left and right channel earphones will be automatically distinguished. The left earphone is the main one and can be paired and connected with a Bluetooth mobile phone. After making a TWS connection, you can play and pause music through both earphones, but only the left (main) earphone has a call function. When the TWS earphones are in an on state, press and hold the power (multifunction) button of one earphone (left or right) for 3 seconds to power them both off. However, when they are in an off state, you need to separately power them on at the same time to reconnect them.
