How to operate the Bluetooth headset?

Try charging the headset for about 2-4 hours for the first time, and then charge it for 2 hours. That's what the instructions say. It's best not to exceed 4 hours. Some forums say that there must be a 24-hour charge, which is unfounded. For such a small earphone, 24-hour charging is somewhat exaggerated. Click Bluetooth Settings in phone settings, select Open, and then finish.

This will turn on the Bluetooth support of the phone. When the Bluetooth headset is turned off, press and hold the headset multifunction button MFB3 for more than 3 seconds. When the blue indicator on the headset lights up, please make sure it stays on. The pairing process is always on, not flashing, and some devices flash alternately in red and blue. At this point, the Bluetooth headset is in a searchable state. Turn on the Bluetooth option on your phone to search.

After searching for the headset, the name and model of the Bluetooth headset will be displayed in the list. Click OK. Enter the password on the mobile phone, and the earphone indicator flashes quickly, that is, the pairing is successful. Click the Bluetooth headset name item you want to open, and then select Binding. When finished, the phone is connected to the Bluetooth headset. At this time, the phone may have a beep similar to connecting usb, and turning off the Bluetooth headset may have a similar beep.

It can be judged whether the Bluetooth headset and the mobile phone are normally connected. You only use your mobile phone to communicate with the Bluetooth headset, and do not exchange information with other Bluetooth devices. You can select the Binding check box.
