PT300A Whole Machine
PT300A does not require any interface cross-linking with the aircraft. It has its own independent battery compartment and antenna for signal transmission and reception. A full charge of the battery compartment can allow the transmitter to work continuously for 20 hours.PT300A also has an external power supply interface, which can be connected to other power supply equipment for long-term continuous operation as needed.
PT300A is compact and comes with an LCD user control panel, which allows for quick and easy parameter configuration according to user needs, effectively reducing the complexity of operations during business conversion and improving user business efficiency.Simple parameter setting operation can be performed by referring to the instruction manual without special training.
