performed with the CTCSS and DCS squelch function activated, scanning stops only
when a signal containing the specified CTCSS tone or DCS code is received.
z Pressing the programmable key on the MH-48A6JA Microphone that is assigned "SQL
OFF" allows signals that do not contain a tone or DCS code, and signals with different
tones, DCS codes, digital mode signals to all be heard.
z Set Mode "DCS INV 11" (see page 29) allows to receive the DCS code of the inverted phase.
