Selecting A Clear Frequency, Checking For Interference - Lectrosonics UCR100 Quick Start Manual

Selecting a Clear Frequency,
Checking for Interference
Turn all transmitters OFF. Turn the UCR100 ON. Slide open the door to
expose the frequency select switches. Set the 100 kHz switch to "8." Rotate
the 1.6 MHz switch to a position where the green RF LED on the front panel
does NOT light up. Then, rotate the 100 kHz switch a few detents above and
below where it was originally set while observing the RF LED. The idea is to
find switch settings where the RF LED does not light up, which will be a clear
operating frequency.
NOTE: Video cameras often generate a
significant amount of RF noise (interference). Mount the UCR100
on the camera or in the position it will actually be used with the audio
cable connected, and check the green RF
LED again to see if interference is present.
If the RF LED on the receiver remains
lit when the transmitters are turned off,
find new switch settings or re-position the
receiver. The RF LED should extinguish
when the associated transmitter is turned
off.
