Page 4 of 5 1) 2) 3) 4) fixed the antenna to the SMA connector for standard operation, connect a DC power +7.5V ~+24V to pin 2 & 1 if need advanced operation, like the pairing operation, please connect a switch between the Pair signal(pin5) and the GND (pin1) switch on the power Now the LED on the transmitter will blink about every 4s. that indicates a ready good working status. B) Recei ver: VW320TSBR Insert the receiver to a DC +5V powers supply which with USB-A female socket. A standard mobile phone charger or the USB port on a PC all can service this job. When being inserted to the USB port, a short beep sound will be heard, as well as the green LED light will be ON. All these give the good ready status of the receiver. If the pai red receiver and the transmi tter within the signals coverage range, the recei ver will give beep sound alert, as well as LED blinks. 11 DD33--441155//441166
