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.
