To ensure proper use of the control gestures on your CMF Buds Pro 2, please follow these steps:

1. locate the touch sensor area:
- The touch sensor area is located at the circular graphic position above the earbud stem. Refer to the instruction manual inside the packaging for the precise location.

2. proper touch technique:
- Make sure you accurately touch the sensor area to trigger the control gestures.

Tips:
- Due to the sensitivity of the touch sensor area, ensure your fingers do not touch the sensor area before you intend to activate a gesture. This helps prevent accidental triggers or misinterpretation of your intended action.

1. When the earphones are connected to two devices, and neither device is in a call state:
1) The earphones will output the ringing sound from the device that's receiving a call.

2. When the earphones are connected to two devices, and one of the devices is already in a call:
1) The earphones will play the incoming call alert and the earphone buttons will prioritise controlling the device that's receiving a call. If the earphones hang up the current call, the audio channel will switch to the other device that's receiving a call.

Note:
Please refer to the product instructions on the official CMF website or get in touch with our Customer Support.

1. When the earphones are connected to two devices, and both mobile devices are in an idle state:
1.1 The earphones will output the sound corresponding to that phone if there is an incoming call or notification on either device.
1.2 If one device starts playing music first, the earphones will output the sound of the corresponding phone.

2. When the earphones are connected to two devices, and only one device is in the music-playing state:
2.1 Incoming or outgoing calls on the device that is not playing music will mute the current music on the earphones (without pausing) and switch to the sound of the incoming or outgoing device. After the call is ended, it will switch back to the connected device playing music.
2.2 If the device not playing music starts playing music, there will be no sound channel switching. Both devices will remain in the playing state and the device that started playing music later will be in a muted state.

1. Reconnection on Lid Open:
1) When dual connection is enabled and the earbuds are powered on, if the earbuds are connected to fewer than two devices, they will attempt to reconnect to the last two connected devices. If dual connection is enabled for the first time with no previous reconnection records, the earbuds will maintain a single-device connection (in single connection mode, the earbuds will not automatically enter pairing mode; pairing a new device requires a manual long-press of the button). If reconnection to other devices fails, the earbuds will stay connected to a single device and will not enter pairing mode.

2) If the earbuds and the terminal device exceed the connection range and then return within range, the earbuds will only reconnect to the phone that was disconnected due to distance.

3) Reconnection will not be triggered when the earbuds are in a call or music state.

4) If the earbuds are in a reconnection state and a call or music scenario occurs, the earbuds will pause reconnection for 5 seconds. If the call or music ends within the reconnection timeout period, the earbuds will resume the paused reconnection until the timeout. After the reconnection timeout, the connection can only be initiated from the device end.

2. Connection Priority:
When the earbuds are in dual connection mode, connection priority follows these principles:
1) If neither of the two phones is in a music state, the earbuds will disconnect from the first connected phone and connect to the device initiating the snatch.
2) When the earbuds enter pairing mode and are already connected to two devices, they will disconnect from one of the devices to be searchable and connectable.
3) If the earbuds are already connected to two devices, and a third device with a connection record initiates a snatch, the earbuds will disconnect from one of the devices and connect to the third device.

Tips:

Music State:
1. If one of the two phones is in a music state, the earbuds will disconnect from the phone that is not in the music state and connect to the device initiating the snatch.
2. If both phones are in a music state, the earbuds will disconnect from the phone whose music is not outputting through the earbuds (i.e., disconnect the device in the muted music state) and connect to the device initiating the snatch.

Call State:
1. If any phone is in a call state, connection snatch is not allowed.
