Menu Navigation
The various menus are invoked by pressing the menu selection keys adjacent to the
associated functions of the front panel. The P400 has no submenus.
Within any menu, the cursor may be moved by using either the up (
), down (
),
left (
), right (
) keys or by pressing and turning the spinner knob. Although within
any menu there are only four lines visible in the display, actual page lengths vary.
One may scroll up and down to see the entirety of any menu page.
There are two kinds of user-settable fields: Numeric and non-numeric.
Non-numeric items are altered by positioning the cursor anywhere within the field,
and rotating the spinner to make selections.
To alter numeric values, locate the cursor beneath the digit of interest and then either
rotate the spinner knob or begin entering digits with the numeric keypad. Keypad-
entered digits will flash until installed by pressing the ENTER key. Digits entered
using the spinner knob will roll over to the next digit when 9 or 0 is reached. Pressing
the clear key (CLR
ι
) will clear all of the digits at and to the right of the cursor.
