picklist values. Pressing the left keypad arrow moves the item selector one
picklist value to the left and pressing the right keypad arrow moves the
item selector one picklist value to the right. When the last picklist value is
reached, and the right keypad arrow is pressed, the item selector will move
to the first picklist value. Likewise, when the item selector is pointing to
the first picklist value, and the left keypad arrow is pressed, the item
selector will move to the last picklist value. An example of a picklist entry
in progress (picklist entry active) is illustrated below:
When the item selector is pointing at the desired picklist value, press the
ENTER key to accept the picklist 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.
If the ESC key is pressed while picklist entry is active, the setting will
revert to the previous value and picklist entry will be 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
