Receiver Installation Method
03
Installation:
① For better operation the receiver should be at least 3ft (1m). above the ground and at least
3ft (1m). away from a wall or metal surface to minimize reflections.
② Attached a pair of UHF antennas to the antenna input jacks, the antenna are normally
positioned in the shape of a “ V ” (both 45° from vertical) for best reception.
③ Keep antennas away from noise sources such as computer, digital equipment, motors,
automobiles and neon lights, as well as away from large metal objects
④ Keep open space between the receiver and transmitter for better reception.
⑤ The transmitter should be at least 6ft (2m). from the receiver

1. After connecting the antenna and the power cable, press the power button to turn on the
receiver. When the display is lit, the power is turned on successfully. (As shown below)
The searched channel automatically calculates the interference-free frequency. The “RF” light on the
receiver display is 0 grid. If not, you can repeat this action until a clean channel is found. (As shown
below)
2.UR-111D Long press “ ” button on the receiver, UR-111S Long press “ ” button on the
receiver to enter Automatic Frequency Search (AFS) function. (As shown below)
