LimitW: Used to change the maximum
default value for power limit.
8. Select the time mode Use the soft keys to select a time mode and
the keypad to enter the run time. Press EDIT.
HRS: Run time is in units of hours.
VHOURS: Run time is in units of volt-hours.
UNTIMED: Run is continuous. Note that steps
