| IntroductionDiscovery Buzzers can be be connected directly to a free PWM channel on an RC receiver but when using a "one wire" RCInput (OPLink, PPM, SBus, Spektrum or SRXL) receivers, direct connection might not be possible. This function is useful when you lost your mini Quad in a cornfield  In this case buzzer can be connected to a free output port, directly to the board. Here is the HobbyKing® Discovery Buzzer that can be used. | Info |

Please note: the previous method using the Custom tab is depreciated. With custom mixer the vehicle is not know anymore as a multirotor and some functions stop working, like ASWA. |

Some know issues : - Be sure the bank (in this example, bank4 - purple) used for the buzzer output channel uses PWM at 50Hz rate. If channel used for buzzer share a bank already used for motor output at higher rates or Oneshot125, buzzer may not work!!
- Be sure the regulated output that power board is not too high, at 6v the buzzer (from HK) stop working.
