ADJUSTING THE SQUELCH
The purpose of the Squelch it to mute the speaker when
no signals are present. With the squelch level correctly
set, you will hear sound only when actually receiving
signals. The higher the squelch level selected, the
stronger the signals must be to receive. The appropriate
squelch level depends on ambient RF noise conditions.
Turn the SQL control when no signals are present, and
select the squelch level at which the background noise is
just eliminated.
SELECTING A FREQUENCY
1 Press [VFO] to select VFO mode.
2 To increase the frequency, turn the Tuning control
clockwise or press Mic [UP]. To decrease the
frequency, turn the Tuning control counterclockwise
or press Mic [DWN].
• Pressing and holding Mic [UP]/ [DWN] causes the
frequency to step repeatedly.
•To change frequencies in steps of 1 MHz, press [MHz]
(Tuning control) first. Pressing [MHz] again cancels this
function.
•To change frequencies in steps of 10 MHz, press
[F]+[MHz] first. Pressing [F] cancels the 10 MHz
function; pressing [MHz] starts the 1 MHz function.
When using a MC-58DM, you can also use its keypad to
select frequencies. See “DIRECT FREQUENCY ENTRY
(WITH MC-58DM ONLY)” {page 61}.
