SECTION I - VEHICLE KEY OPERATIONS
these options is described below:
• COMMERCIAL SYSTEMS: The entry is not verified, which means that no
matter the entry, it is accepted and recorded without regard to accuracy. In
addition, since any number is accepted, this entry cannot be locked-out (de-
authorized). [DEFAULT]
• VMN SYSTEMS: The entry is verified against an authorization list stored in the
FMU. If the entry is invalid, a total of 5 attempts to enter a valid USER ID are
afforded the user. Upon failure to enter a valid USER ID, an error message is
sent to the on-site printer stating that an invalid user id was entered and the
process begins again. This method requires entry of an authorized number and
allows these numbers to be locked out (de-authorized).
If the ODOMETER/CHRONOMETER option is enabled for this
Vehicle Key, the following prompt will appear:
Enter the miles or hours (without tenths) on the FMU keypad. Once
entered, press ENTER/YES on the keypad.
What occurs next is very important and causes much user
confusion. When the Vehicle Key is first inserted, the FMU looks at the
MILES/HOURS range that was encoded on the key. The FMU then looks
at the miles/hours that were entered and written back to the key during the
previous 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:
**
**ENTER CHRONO/ODOMETER ---> **
***** FUELMASTER
* ODOMETER TOO LOW! PLEASE TRY AGAIN.
