Step 2 Establish Bluetooth Connection
Turn on the Bluetooth on the phone, search for the Bluetooth device, find the device, connect
the device and confirm "pairing". At this time, "Pairing Request" pops up in the status bar at the
top of the device screen, click "Pairing and Connecting" to confirm pairing.
Step 3 Mute and Volume Adjustment
Use the "Mute button" on the device panel to switch the mute or pickup state of the built-in
microphone.
Press the volume key on the device panel to adjust the volume of the built-in speaker. Use
the Bluetooth audio gain control in the "Audio Console", adjust the Bluetooth audio input

5.3 Connect Gooseneck Microphone
Gooseneck microphones are required for some usage scenarios. The device can be connected
to an external gooseneck microphone, so that the built-in microphone and gooseneck
microphone can pick up sound at the same time, or only the gooseneck microphone can be
used to pick up sound. The specific steps are as follows:
Step 1 Connect Gooseneck Microphone
Connect the gooseneck microphone to the 3.5mm interface on the right.
Step 2 Interface Configuration
Short press the floating ball on the system desktop to open the Audio Console application.
Browse the upper right corner "Audio Settings"> "Advanced Settings"> 3.5 interface
settings on the right and select "MIC" as the input type.
Enable audio loopback (optional). If audio loopback is enabled, the sound picked up by the
gooseneck microphone will be output from the built-in speaker of the device. At this time,
the device is used as a local loudspeaker.
Step 3 Adjust Input Gain
Please adjust the input gain of the gooseneck microphone in the Phone3.5 gain bar in the
Audio Console. For details, please refer to the "Phone3.5 & Bluetooth" section of the "Audio
Control" section of this document.
