by contacting Syn-Tech Systems Product Support.) Once the USER ID is
entered on the FMU keypad, press the ENTER/YES key to receive the
next prompt.
The Central Controller is capable of encoding selected Vehicle Keys to
require the entry of a User or Miscellaneous value at the time of fueling.
This entry is not verified. This means that entries are accepted and
recorded without regard to accuracy. In addition, since any number is
accepted, locking out (de-authorizing) the user is not possible.
If the ODOMETER/CHRONOMETER option is enabled for the key, the
following prompt is displayed:
Enter the miles or hours (without tenths) on the FMU keypad. Once
entered, press the ENTER/YES on the keypad.
What occurs next is very important and causes much confusion.
When the Vehicle Key is first inserted, the FMU looks at the
MILES/HOURS range that was encoded on the key and compares it to the
miles/hours that were entered and written back to the key during the last
fueling transaction. The FMU then calculates the miles/hours elapsed and
compares it to the value just entered and sends the appropriate prompt to
the FMU display screen.
One of the following three messages will appear:
This error message indicates that the entry made is lower than the entry that was
written to the key during the previous fueling transaction on this vehicle.
This error message indicates that the entry has an elapsed mileage or hours that
are greater than the MILES/HOURS range encoded on the key. One of the
following may have occurred:
NOTE:
