SECTION 2 -- CONTROLS, INSTRUMENTS AND OPERATION
2--61
Setting the Implement Width
In order that the micro-processor may calculate the
cumulative area, the working width of the implement
must be entered into the memory. For example, to
enter an implement working width of 4.5 metres
(14.76 ft.) carry out the following procedure.
• With the key--start in the ON position, depress
and hold the Menu/Enter key for 3 seconds. The
DMD will read SETUP_MENU, this will change
to CAL after 2 seconds. Using the Menu
Up/Down keys, scroll through the menu until the
implement width symbol is displayed.

• Depress the Menu/Enter key again to select the
set--up screen, a flashing cursor will appear at
the first number to be set. Using the Digit Value
key enter ’0’ then move the cursor one space to
the right with the Digit Select key and enter ’4’.
Move the cursor to the right of the decimal point
and enter ’5’. The reading displayed should now
be 04.50 mtrs (14.76 ft.).
• Touch the Menu/Enter key to store the setting
and return to the main menu.
NOTE: The micro--processor cannot calculate the
area worked unless the correct implement width is
entered.

Calibrating for Wheel Slip
(where fi tted)
Before setting the slip alarm point, a zero wheel slip
factor has to be determined. This calibration must be
carried out on a hard level surface where wheel slip
is unlikely to occur .
NOTE: The Electronic Draft Control auto slip
function (see EDC operation) will not operate unless
this procedure is carried out.
• With the tractor stationary and the engine
running, depress and hold the Menu/Enter key
for 3 seconds. The DMD will read
SETUP_MENU, this will change to CAL after 2
seconds. Using the Menu/Enter key, scroll
through the menu until the wheel slip symbol is
displayed.
• Drive the tractor at a constant speed above 5
Km/h (3.1 MPH). When a steady speed has been
reached, depress the Menu Enter key, CAL ON
will appear in the display. After a short distance
touch the Menu Enter key again, the display will
change to CAL OK.
• Touch the Menu/Enter key to store the setting
and return to the main menu.
