UX800R SQUELCH
(rear panel)
The SQUELCH setting is used to reduce interference by rejecting background RF signals that fall
below the SQUELCH level. Increasing the SQUELCH setting will increase the level of RF signal required to pass an
audio signal through the receiver. If the SQUELCH is set too high it may cause elimination of the audio from your
transmitter. Also check the RF power setting on the microphone.

00R RECEIVER SETTINGS
»
EDIT SETTINGS: Press the MENU button until only the setting you want appears on screen. Adjust the setting
with the UP/DOWN buttons. Set the receiver and the microphone transmitter to the same Group and Channel
(or Frequency). Each transmitter must be set to a different frequency and matched to the receiver it will work
with.
»
IR SYNC: Automatically matches the operating frequency of the receiver to the transmitter. 1. On the receiver,
press the front panel MENU button 4 times until “IR” is displayed on the top line of the display. 2. Hold the
microphone transmitter within 8 inches of the receiver, so the IR port on the microphone transmitter points
toward the IR port on the receiver (inside the white circle above the “IR.))))” symbol). 3. On the receiver, press the
UP button to start the sync, holding the transmitter in place until the sync is complete and “IR” is not shown in
the display.
»
GROUP and CHANNEL manual setting: 1. Press MENU once and select a GROUP with the UP/DOWN buttons.
2. Press MENU again and SCAN will show on screen (see SCAN). 3. Press MENU again to manually select a
channel with the UP/DOWN buttons, or press the UP button to SCAN for an open channel.
»
SCAN: The SCAN feature skips over busy or noisy frequencies and is helpful when using the UX800 system in
the same area as other wireless devices. To use the SCAN function press MENU twice. When “SCAN” is
displayed, then press the UP button. The next open frequency channel is chosen.
»
FREQUENCY: (example: 471.100 MHz) If a GROUP and CHANNEL is selected, the FREQUENCY is automatically
set and should not be changed. NOTE: The GROUP-CHANNEL method is recommended when using multiple
systems. Frequencies can interfere with each other due to combinations of carrier signal waves.
The GROUP-CHANNEL presets are calculated to avoid this type of interference between wireless channels
operating within the same group.
»
MASTER MODE: Allows you to select any of the 400 frequencies available. The microphone transmitter must
also be set to MASTER MODE. IR SYNC can still be used. Select a Group that displays a “U” in the Channel area,
then press MENU again. Press the UP or DOWN to change frequency in 0.050 MHz (50kHz) steps.
Hold the UP or DOWN button to scroll faster through frequencies. NOTE: The GROUP-CHANNEL method is
recommended when using multiple systems. Frequencies can interfere with each other due to combinations of
carrier signal waves.
»
LOCK MODE: Prevents accidental changes or tampering when engaged. To LOCK the controls, hold MENU and
press UP. The lock symbol will appear on the screen. To UNLOCK is the same, hold MENU and press UP.
