Precautions

•This product is used as the antenna integrator of the receiver, which is not recommended to be used with a transmitter.

• For the coaxial cable with antenna and UC-900RX, standard 50Ω coaxial cable must be used.

• When the antenna is connected to the unit with the coaxial cable, it is recommended to use Booster to compen sate for

cable loss or use 5D-FB coaxial cable.

• It is not advisable to place the antenna in the same space or where there are too much reflecting planes as they cause

multipath interference of the signal and affect the reception quality.

• When the antenna input signal is too large, it may cause distortion of the unit or receiver signal. If this is the case, try

adjusting the antenna input attenuation.

• When the power supply is abnormal, the panel light will flash and the machine will force to shut down all the corresponding

functions. Please turn off the power switch immediately.

Caution : To reduce the risk of fire or shock hazard, do not expose this appliance to heat or moisture.
Warning : To prevent electric shock, do not remove the cover. Refer all servicing to qualified service personnel or distributors.

1.

Read this instruction manual before using.

2. Keep this instruction manual.

3. Use the device in a well ventilated area. Do not block any ventilation openings.

4. Do not install the device near heat sources, Ex : Oven, furnaces or any other

apparatus that produce heat to prevent fire.

5. Do not place the device in humid or dusty environment to prevent short circuit.

6. Choose proper place to place the device to avoid product failure or personal

injury caused by accidental drops.

7. Do not use the device under lighting to avoid personal injury or equipment

damage caused by strikes.

8. Stop using and turn off the power when encounter abnormal situation. Contact

qualified service personnel or distributors.

> Machine has smoke or burning smell

> Water or any liquid has been spilled

9. Keep the machine outlet or plug clean. Dust gathering may result in bad

connection or electric fire.

10. Pay attention to the cable usage

> Hold the plug when unplugging. Breaking the wire may result in electric fire.

> Do not cut or twist the wire. Place the wire in a well ventilated area without

inflammable objects.

Instruction Manual

The UC-900RX is designed for receivers. It provides 2 x 4 antenna inputs to minimize RF dead zone on a stage or any
venue. It also feature RF input ON/OFF, input attenuation from -31 to 0 dB and input signal ON/OFF control. The
UC-900RX makes RF engineers’ job easy.

Installation

• Connect the antenna through the coaxial cable to the antenna input. If the cable length is long, add the antenna booster or use

active antenna.

• Connect the antenna A / B output to the receiver or antenna distributor with coaxial cables.

• When the installation is complete, turn on the power. Depending on the situation, the user can set the relevant parameters

according to the operating instructions.

• When not in use, turn off the UC-900RX power.
