Function changes will change the operation of the unit. The ability to change functional parameters
from the keypad may be disabled depending on fleet requirements.
Pressing and holding the FUNCTION key for more than 3 seconds will initiate the Pretrip Function.
The Function Parameters control selected operating features of the unit. When multiple choices are available, the
display will show the function description on the left side with the corresponding function choice on the right side.
With a function parameter displayed, the data choice can be changed by pressing ENTER then pressing either the
UP or DOWN arrow keys. The displayed choice will then flash to indicate that the choice has not been entered.
Depress the ENTER key to activate the new choice. The display will stop flashing to indicate that the choice has
been entered.
All functional parameters are retained in memory. A description of the function is displayed on the left side with the
corresponding data on the right side. Press the FUNCTION CHANGE key or use the UP/DOWN arrow keys to dis-
play the functional parameter list.
With each press of the FUNCTION CHANGE key, the list advances one. If the FUNCTION CHANGE key is pressed
and held for one second, the list advances one item at a time. The function list loops, which means that once the end
of the list is reached it goes back to the first entry.
While the functional parameter is displayed, the data can be changed by pressing ENTER and then pressing the UP or
DOWN arrow keys. If the value is changed, the displayed data flashes to indicate that the value has not been entered.
If the new value is not entered in five seconds, the display reverts to the last entered value. If the ENTER key is
pressed, the display stops flashing to indicate that the value has been entered. The new value will continue to be
displayed for five seconds before reverting to the default display. Each time a key is pressed, the five second delay
is reset. To select a different functional parameter the FUNCTION CHANGE key must be pressed first.
The following sections describe the list of functions which can be modified via the keypad.
