Precauções para uso

1. Atenção: Please connect only one of 110~240V and 28V on the transmitter. Please connect only one of 110~240V and 12V on the receiver.
2. o DC power supply of the transmitter is 28V, 4UMA, and the receiver is powered by 12V.
3. o power switch on the front panel of the transmitter controls 110-240V AC. The DC power supply of the transmitter rear panel is connected to the car battery or battery for direct power supply. (28VDC has no power switch control)
4. The 110-240V and 28V of the transmitter cannot be powered at the same time, choose one of them.
5. A1/A2 on the front panel of the transmitter switches the front microphone input or the rear panel microphone input. Pressing the button is the microphone audio input of the front panel of the transmitter, connected to the built-in amplifier. For non-powered microphones.
