date/time on the DV-1 unit.
Setting the date/time of the unit forward reduces the number of
Loaner days by the number of days the date/time was set ahead.
Setting the date/time of the unit back does not affect the remaining
number of Loaner days. The number of Loaner days remains the
same.
Press Extend on the MAINTENANCE UNIT screen to start the
process to extend the loaner time period on the DV-1 unit. The time
extension can be from 1 to 99 days.
