Features
 Hold
L AB E L S
{7} to toggle on or off the function key labels located at the bottom of the
screen, just above the function keys (Pages 11 and 12).
 Tap
M E N U
{7} and use the
SELECT
knob {8} to scroll through the list. You can tap or
hold one of the function keys {3-6} to assign the currently-displayed function to the key. If
the function key labels are on, the label for that key will change to show the selected
function (Page 11).
 Tapping the SELECT knob {8} while the menu is active causes the currently-selected
menu function to execute. Select LCD Brt from the menu and tap the knob. The knob now
adjusts the brightness of the LCD display backlight. Tap the knob again to exit the
selection or tap MENU {7} to select a different menu item. Some menu items are toggle
functions. Instead of changing the parameter by turning the SELECT knob, it changes
automatically whenever the knob is tapped. The new value is displayed briefly near the top
of the spectrum display. Menu items are listed on page 33.
 Tap
M K R A
{9} or hold
M K R B
{9} to turn on marker A or B. Rotate the
SELECT
knob to place the selected marker at a desired frequency on the display. Markers may be
used to measure the frequency of an interesting signal and, if the transceiver is a K3,
tapping the knob will QSY (change the frequency of) the K3 to that frequency.
M K R A
controls the K3's VFO A and
M K R B
controls VFO B. The marker colors match the
corresponding VFO cursors to emphasize the correspondence. Whichever marker is
currently selected is the one that causes the K3 to QSY (Page 11).
 To return from the last QSY ("undo" function), hold the
SELECT
knob pushbutton. To
turn off marker A, tap
M K R A
{9} while marker A is selected. To turn off marker B,
hold
M K R B
{9} while marker B is selected.
 Tap
S P AN {10}
to set the frequency span of the display. The start and stop frequencies are
displayed at the top (left and right edge respectively) of the spectrum window (Page 11).
 Hold
C E N T E R
{10} to set the center frequency of the display (Page 12). This function
may be disabled when in tracking mode via the MENU:CenterEn function.
 Tap
R E F L V L {11}
to set the amplitude reference level of the display, both spectrum and
waterfall. The term "reference level" means the signal level that corresponds to the bottom
of the spectrum display (Page 12).
 Hold
S C AL E {11}
to set the scale, or range, of both the spectrum and waterfall displays.
For example,"60 dB" means that the bottom of the display is 60 dB below the top (Page
12).
 Hold
AV E R AG E {12}
to turn on display averaging and allow adjustment of the averaging
time (Page 12).
