Editing the
Current Value To change the current value of a parameter by edit-
ing, you can use either the cursor control key or the
rotary data knob.
Using the Cursor Control Key
Using the < and > pads of the cursor control key,
move the cursor under the digit where you want to
begin editing. Then increase or decrease the value of
the parameter using the
Ù
or
Ú
pad of the cursor
control key. The unit size of the increase or decrease
that occurs each time the
Ù
or
Ù
pad is pressed is de-
termined by the cursor position.
Using the Rotary Data Knob
You can also increase or decrease the value of the
parameter using the rotary data knob. Once you
have positioned the cursor under the digit where
you want to begin editing, slowly turn the knob
clockwise or counter-clockwise to increase or de-
crease the value of the parameter by the unit size.
Turning the knob rapidly changes the value of the
parameter in larger steps.
Using a Set Increment
When editing frequency, power level, and time pa-
rameters, you can increase or decrease the parame-
ter’s value by a set amount each time the
Ù
or
Ú
pad
is pressed or the rotary data knob is turned clock-
wise or counter-clockwise. For instructions on set-
ting the increment size, refer to paragraph 3-13.
Now, try changing the current value of the CW fre-
quency displayed on your synthesizer from 2.0 GHz
to 6.395 GHz. Use both the cursor control key’s
Ù
and
Ú
pads and the rotary data knob to make the
value changes. When you are finished, your menu
display should look like the example below.
To close the open parameter when you are finished
editing , press
Edit F1 or make another menu selec-
tion.
