Fine Adjust Knob Operation

asterisk (*) indicating that numeric entry is active. An example of a

numeric entry in progress (numeric entry active) is illustrated below:

Once the numeric value has been entered, press the

ENTER

key to accept

the numeric value. Values are not applied to the operation of the Model

430 Programmer until the

ENTER

key is pressed and the asterisk

disappears from the display. Attempts to set a parameter to a value

outside of the valid range are ignored, and if attempted the Model 430

Programmer will beep once indicating an error and revert to the previous

setting.

If the

ESC

key is pressed while numeric entry is active and digits have

been entered, the entered digits will be cleared and the cursor will remain

for reentry of a new desired value. If the

ESC

key is pressed with no

entered digits on the display, the setting will revert to the previous value

and numeric entry will be made inactive. Thus, if digits have been entered,

the first time

ESC

is pressed, the entered digits are cleared, but numeric

entry remains active; if

ESC

is then pressed again (with no entered digits

displayed), the setting reverts to its previous value and numeric entry is

made inactive. Note that if the

ESC

key is pressed when numeric entry is

not active, the current submenu will be exited and the next higher level

submenu will be entered.
