7. "SCAN (DS)" button: With this control, you can automatically seek for a busy channel.
Turn the Squelch clockwise until the background noise is no longer heard.
Press the "SCAN" button: the transceiver will scan automatically all the channels.
If you switch on the unit and push "SCAN" and "AM/FM"(LCR) at the same time, you
will select the operating band, which will be visualised on the display.
DS (Digital Automatic Squelch): differently from the standard squelch, the D.S.
automatically detects the squelch level that allows a clear reception of all incoming
signals, there's no need to make any further adjustment. This function also eliminates
the unwanted background noise in absence of incoming signals.
To select the automatic squelch:
• Turn on the radio.
• Press briefly the SCAN (DS) button. As confirmation of your selection, the display
shows AS in the top right corner, in place of the frequency band in use.
8. "Squelch" Control: For the maximum receiver sensitivity, the control must be regula-
ted exactly where the receiver background noise disappears.
9. "ON/OFF Volume" Control. In "OFF" position your transceiver is OFF. Turn this con-
trol clockwise to switch on the unit. Turn the knob clockwise a little more to set the audio
level, until you get a comfortable reception.
10. Microphone jack: Insert the mic connector into this jack.
