Page 3: General Technical Description
The antenna phase SMART switching diversity technique was front ends, this was a daunting task. Lectrosonics has always used chosen in order to keep the receiver compact enough for camera front ends with more sections and much more selectivity than any mounted or shoulder bag applications. - Page 4 The UCR310 is unique in that it uses a state of the art SAW filter in present at the time. If the RF level is weak, then the filter becomes the IF section.
- Page 5 +8dBm with no front panel control. POWER SUPPLY The UCR310 may be operated from an external DC source (see Specifications and Features section for allowed voltages.) The power supply has a built in Poly-Fuse to protect the unit. This fuse resets if the power supply is disconnected for about 15 seconds.

Page 8: Antenna Use And Placement
Be careful about the length of cabling from antenna to receiver. This may alleviate the drop-out problem on that antenna. If Long cable runs can have serious signal loss. Lectrosonics has in- drop-outs are still a problem, try moving the antenna to an line RF amplifiers suitable for compensating for long cable runs. -
Page 9: Installation And Operating Instructions
If the output is too low, you may hear steady noise (hiss) along with the audio. The UCR310 audio output is designed to drive any audio input device from microphone level to +8dBm line level. -
Page 10: Frequency Blocks And Ranges
The usable bandwidth of the A8U antennas are +/- 50 MHz from the center frequency, so it is acceptable to Each UCR310 receiver is built to cover a pre-selected range of use an antenna from an adjacent block above or below the frequencies (a “block”) as shown below. -
