4.2 using Bluetooth hands-free function

4.2.1 for the first time to use the hands-free function needs the code. The way to code is to turn on the Bluetooth function of the cell phone and search it. When the cell phone searches the Bluetooth machine, it will bind the cell phone. The first binding needs to input the initial password 0000 on the phone. After the connection is completed, the phone can be answered and dialed by hands-free.

4.2.2 if the phone and the hands-free player have been over the code, and the phone set allows Bluetooth to connect automatically, the hands-free player will automatically connect to the phone when it is powered up. (if the cell phone is not allowed to automatically connect to the Bluetooth, the cell phone will be prompted to connect, the different mobile phones will be slightly different)

4.2.3 when your mobile phone Bluetooth MP3 when playing music calls, the player will automatically switch to the mobile phone hands-free state, press the answer key to realization of Bluetooth speakerphone function, after the call is automatically switched back to the music player, can also press the answer key to hang over the phone Bluetooth

4.2.4 explains:

1, A2DP function. The mobile phone with A2DP function, that is, the stereo Bluetooth, can be called by AV connection function (some phones are called music expansion play, etc.), and the connection method is the same as above. Music on the car's sound can be played on the phone.

2, different Bluetooth services for different phones can be connected at the same time, but the same service can only connect a cell phone at the same time. For example, if A mobile phone is connected to the phone call function, B phone must disconnect the A phone if it wants to connect the call function, but if the B phone has A2DP function (A cell phone does not connect A2DP function), B phone can also connect to A2DP function alone. That is, A phones can be free to call, and B phones can play music through the Bluetooth player. At this time, if a caller or a phone is called, the phone will have a priority. The phone will automatically turn to the A2DP playback function after the end of the phone.

3, priority: when different functions are used, the priority is as follows

Mobile phone call >a2dp play, U disc music play, SD card music play

In this priority order, any high priority function is activated, the low priority will be suspended, and the low priority will be restored after the high priority function ends.
