Soft Keys
The soft keys (3) are the six physical keys that are located immediately beside the LCD. Soft keys (3) are used in order to operate the function that is shown on the soft key label that is located to the left of the soft key.
Soft Key Labels
The soft key labels (2) are graphical keys that appear at the right side of the screen. In order to activate the displayed function, press the soft key that is directly beside the soft key label. For example, in order to change the blade focus, press the soft key that is located directly beside the soft key Label that contains "Blade: Left" or "Blade: Right".
Soft key functions relate to the particular screens or dialogs. These functions are only available when these screens or dialogs are accessed. For example, "New Level" only appears on the "Design Selection" screen, as that function relates only to that screen.
If a soft key has no function in a screen or a dialog, the label for the soft key is blank.
The text on a soft key label can show one of the following details:
- A description of the operation that is performed is shown when the soft key is pressed once.
- The setting that is currently selected. The text on the soft key label changes when you press the soft key to switch between options. The top line of this soft key label ends with a colon and the bottom line shows the current option or setting. For example, the soft key labels "Blade:Left" and "Blade:Right" shows the side of the blade that is selected for horizontal guidance on Three dimensional systems. The current end (Left or Right) shows on the bottom line of the label.
Some soft key labels (2) will appear in more than one dialog. The function of the soft key is the same function.
Guidance Soft Key Descriptions
| "Blade:Right/Left" - This soft key allows the operator to choose the left side of the blade for focus or the right side of the blade for focus. The current focus (Left or Right) shows on the bottom line of the soft key. |
| H. Offset - This soft key allows the operator to choose a line from the Plan View. Additionally, this soft key allows the operator to set an offset to the horizontal alignment. |
| "V. Offset" - This soft key allows the operator to change the vertical offset of the working surface. The remote switches can also be used. |

"+" Key
The "+" key (7) is used in order to zoom in the current view. When you zoom in you see more detail on the screen. As you zoom in, less of the design and linework are shown. You can zoom in until the blade fills the screen.
Holding down on the "+" key (7) allows the operator to zoom to the machine in order to resize the current view around the machine symbol. This feature is only available in the "Plan View" and "Cross-Section View" when a design is loaded. In "Plan View", zooming the machine will display five blade-widths around the machine. In "Cross-Section View", zooming to the machine will display 2 blade-widths on either side of the machine.
"-" Key
"-" key (9) is used in order to zoom out the current view. When you zoom out, you see less detail on the screen. As you zoom out, more of the design and linework are shown. You can zoom out so far that the machine is barely visible on the screen. When you zoom out to this degree, the machine symbol is no longer drawn to scale. Keeping the machine symbol makes sure that you can always see the machine symbol in the current view.
Holding down on the "-" key allows the operator to zoom to the whole design. This feature is only available in the plan view and cross-section View when a design is loaded.
Display Brightness
The display brightness can be adjusted by holding the menu key and pressing the "+" key or the "-" key.
Data Card Slot

| Illustration 3 | g01295064 |
The display has a slot for a data card (12) that allows the use of a CompactFlashTM card. The data card slot (12) allows the user to perform the following tasks:
- Restore machine and display configuration data
- Store machine and display configuration data
- Load design data
- Save design data
Data Card and Data Storage
Construction designs are developed in the office and translated to a format that is easily read by the display by using AccuGrade Office Software. The designs are then saved onto a data card in order to be read by the the AccuGrade System. The AccuGrade System interprets the designs above the blade cutting edge or below the blade cutting edge in order to provide guidance.
When the door for the data card is opened, a red screen appears on the display that prompts you not to remove the card. Do not remove the data card until the red screen is not present. If the data card is removed while the screen is red, the data card may be corrupted.
In order to insert a data card, complete the following steps:
- Press the tab that is located below the data card slot (12) in order to open the flap. The slot is below the LCD on the display. Refer to Illustration 3.
- Insert a data card.
- Lower the flapuntil the flap latches.
You can use the AccuGrade display in order to perform the following tasks on a data card:
- retrieve files
- save files
- retrieve files
Working with Dialogs
The "system setup", "alignment selection", "horizontal offset" selection, "vertical offset" selection, "design selection", and the "Setup Menu - Configuration" option screens are called dialogs. Use dialogs in order to enter data. Use the dialogs in order for the AccuGrade System to be set up according to your requirements. The selected field in a dialog is identified by the blue background color.
Press the next key (5) on the display in order to move to different fields within the dialogs.
Press the arrow keys (8) on the display in order to enter data:
The up arrow steps through the upper case letters "A through Z", the numbers "0 through 9", the decimal point ".", the negative sign "–", the positive sign "+", a space, and back to "A".
Note: Available values will depend on the type of field that is selected. For example, the only values that are available for number fields are 0 through 9, the decimal point ".", "–", and "+".
The down arrow steps through the same character set, but in reverse.
When you change a character in a field, the up arrow and the down arrow start stepping from the existing character.
The right arrow steps to the next character to the right. In fields that allow spaces, press the right arrow twice in order to insert a space.
The left arrow is used in order to move back one character to the left. This deletes the character in the space to the left.
Dialogs may contain any of the following items:
Text fields - Use the text fields in order to enter your own information. For example, when you set up the name of your level surface design or sloping surface design, use the Arrow keys (8) in order to enter this data.
Number fields - Use the number fields in order to enter required values. For example, when you set up the vertical and horizontal offset, use the Arrow keys (8) in order to enter values into these fields.
List boxes - Lists options or possible selections. Use the Arrow keys (8) in order to select the listed item.
