6.2.3. Squelch level setting
The WT-5800/5805 tuner has the squelch function that virtually eliminates ambient noise and unwanted audio
signals from other wireless microphone systems by silencing the output when the signal received is lower than
a certain level of signal strength. This strength level can be varied by means of the squelch control.
Step 1. Press the Set key for over a second to place the unit in setting mode.
Step 2. Select the setting item "SET SQ LEVEL" with the Up or Down key.
Step 3. Press the Set key, and the squelch level adjustment display "RF >" appears on the screen.
Step 4. Set the squelch level referring to the on-screen bar-graph meter (6 segments) which can be changed
with Up or Down key.
Step 5. Press the Set key to register the selected value.
This terminates the Squelch level setting, and the display returns to the "SET SQ LEVEL" indication.
Note
When leaving the original value unchanged, select "Exit" with Up or Down key and press the Set key.
Then, the display returns to the "SET SQ LEVEL" indication.
Step 6. When any other setting is not needed, select "Exit" with the Up or Down key and press the Set key.
The unit returns to the normal operating state.
The squelch level ranges from "0" to "6." The wireless tuner's sensitivity is the highest and radio signals can
be received in wide areas when the "0" level is selected, while the "6" level makes the sensitivity the lowest,
limiting signal reception only to narrow areas.
The wireless microphone's signal transmission distance varies largely depending on its ambient conditions.
The table below provides guidelines on the squelch level vs. transmission distance.

Note: Transmission distance is a relative ration with respect to 100% at "0" level.
Tips
• Set the control to the "0" position in locations free from interference.
• Set the control to the position that does not cause any reception loss of wireless microphone signals.
