15 Squelch (Muting)
The EM 3532 receiver is equipped with an adjustable squelch which eliminates annoying noise when the transmitters are switched on and off. It also suppresses sudden noise when a transmitter leaves the reception area and there is no longer sufficient transmitter power received by the receiver.
The adjustment of the squelch is via the “SQUELCH” menu. The adjustment range is between 0 and 134 (on the display), which corresponds to 0 to up to 100 μV. When the squelch is active, the display “MUTE” is lit up on the display panel. If set to position “0”, the squelch is switched off.
Press the / buttons to select the “SQUELCH” menu. Then press the SET button. The LC | |||||||||||||||||||||||||||||||||||||||||
| dot on the left of the text SQUELCH begins to flash and the current value of the squelch | ||||||||||||||||||||||||||||||||||||||||
| is shown on the alphanumeric main display and in the deviation bargraph. For the exact | ||||||||||||||||||||||||||||||||||||||||
| value in μV please refer to the RF level bargraph on the left of the deviation bargraph: | ||||||||||||||||||||||||||||||||||||||||

With the / buttons you can now select a squelch threshold between 0 and 134. |
Only after having been stored does the new squelch treshold become effective. To store a setting, press the SET button until “Sto” briefly appears on the display, indicating that your setting has been stored. The display then switches back to the standard display.
You can discontinue the programming of this menu by briefly (!) pressing the SET button. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.
If you do not press any of the three programming buttons for more than 30 seconds, the setting mode is automatically left. The display briefly indicates “ESC” and then switches back to the standard display. The previous settings are kept.
