Quick Keys
There are two dedicated adjustment keys on the front of the unit (refer to Figure 3) that become
active when accessing a menu item. These keys change choices of a menu item while that item
is highlighted on the display. The left adjustment key will decrease the value of an item, and the
right adjustment key will increase the value of an item. If there are no choices available for a
particular menu item, or if that menu item is for reference only, the adjustment keys will have no
effect.
The item data will be automatically saved when either of the

/

soft keys are used to highlight
a different menu item, or when the

(
ENTER
)
soft key is pressed. Pressing the ESC soft key
while the menu item is still highlighted will discard changes and restore the item to its last saved
value.
NOTE: When programming a numerical menu item, continuously pressing a quick adjustment
key will scroll through the values faster than if they key is repeatedly pressed and
released.
