When the desired numeric value has been set using the fine adjust knob,
the ENTER key is pressed to store the value. Pressing the ESC key while
the fine adjust knob is live will cause the adjusted value to revert to its
previous setting and make the fine adjust knob inactive. In fact, pressing
any key other than ENTER will cause the adjusted value to revert to its
previous setting and make the fine adjust knob inactive.

change the value to another value in the picklist, first press the ENTER
key; the display will show an asterisk (*) indicating that picklist entry is
active.
While picklist entry is active, the left and right keypad arrows (to the left
and right of the MENU key) move the item selector between the different
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
