5.1 Charging the Microphone
Before initial use, fully charge the microphone. Use the provided USB charging cable to connect the microphone's Type-C port to a standard USB power source (e.g., computer USB port, USB wall adapter).
- Connect the Type-C end of the cable to the microphone's charging port.
- Connect the USB-A end to a 5V/1A power adapter or a computer's USB port.
- An indicator light (if present) will show charging status. Refer to the specific model's indicator behavior for full charge notification.
5.2 Pairing with Your Radio
The microphone connects to your compatible radio via Bluetooth. The pairing process may vary slightly depending on your radio model. General steps are:
- Power On Microphone: Press and hold the Power button on the side of the microphone until the indicator light turns on.
- Enter Pairing Mode: The microphone should automatically enter pairing mode upon first power-on or if no previous device is found. If not, consult your radio's manual for specific instructions on how to initiate Bluetooth pairing on the microphone (e.g., holding the power button longer, or a dedicated pairing button).
- Activate Bluetooth on Radio: Turn on the Bluetooth function on your compatible car radio (e.g., VR-N7500, N7600, ZASTONE D9000APP).
- Search for Devices: On your radio, search for available Bluetooth devices. The microphone should appear as 'BHM-78' or 'BHM-79' or a similar identifier.
- Select and Connect: Select the microphone from the list of found devices on your radio to establish the connection.
- Confirmation: A successful connection is usually indicated by a steady blue light on the microphone or a confirmation message on your radio's display.
