Getting started cont. Setting Up on Stage If you will be using the UHF-6800 with stage monitors and/or a P .A. system, try the following: • Place the stage monitor directly behind the microphone. • Locate the P .A. loudspeakers so that they point away from the rear of the microphone. (With the speakers located in these positions, the possibility of feedback is greatly reduced).

Operations cont. Frequency By locking a frequency, you can prevent the user from accidentally changing the frequency. To lock the frequency on the Receiver 1. Choose which mic channel that you are changing the display for, either Microphone Channel A or Microphone Channel B.
Operations cont. Adjusting the Squelch If you are experiencing signal interference, try turning the squelch higher to eliminate unwanted interference signals. Squelch isolates the strongest signals and cuts out the weaker ones. To adjust the squelch: 1. Using a small flat-head screwdriver, adjust the squelch by turning clockwise to increase it and counter-clockwise to decrease it.
