Bluetooth connection interface:

After opening the Bluetooth interface of the mobile phone, after displaying VHM-314 V3.0, click the name to connect and use. After the connection is successful, a "ding dong" prompt will sound, and when you disconnect, there will be a "deng deng" sound.

Instruction and Warm Tips:
  1. Please use a maximum of 5V power supply for the BAT interface, which can be directly powered by a 3.7V lithium battery.
  2. The maximum charging voltage of the MICRO interface must not exceed 6V.
  3. The toggle switch can only control the battery switch, and the power supply can only be switched after the USB is inserted, whether it is battery power or MICRO power supply.
  4. When there is only MICRO power supply, toggle the switch to the MICRO terminal to avoid the sound quality damage due to insufficient power supply current.
  5. VHM-314 does not have a charging version, you cannot directly charge a lithium battery without a lithium battery protection chip
