How change day on which 7 day exercise occurs for 45KW Generac…

Here is what the tech manual says about,

NORMAL EXERCISE MODE
To select this mode, place DIP switch position 3 in
the ON position.
In Normal Exercise Mode the 2.4L and 3.0L generators
will exercise at 3600rpm.
The R-200 controller will start and run the generator
once every seven (7) days for approximately 12 minutes.
If the utility fails during the exercise period, this
exercise period is aborted and the R-200 Controller
transfers the load to the generator output, assumes
automatic operation and continues to run until the
utility is returned.
The weekly exercise cycle is set as follows:
1. Place the AUTO/OFF/MANUAL switch in the
AUTO position.
2. Press and hold the "Set Exercise Time " switch for
five (5) seconds and then release.
At this time all five (5) red LED's will flash for 10
seconds, then the engine will start and run for it's
12 minute exercise period, then shut down. The generator
will now start and run each week at approximately
the same time.
If battery power to the R-200 Controller is lost, the
weekly exercise time setting will be lost. This is indicated
by all five (5) red LED's continually flashing in
ATS mode. In this state the generator will still start
and run in MANUAL mode, or automatically start
and run if utility voltage is lost while in AUTO mode,
but it will NOT perform a weekly exercise cycle.
In the event of a failure while running in this mode,
the five (5) red LED's will stop flashing, the individual
fault LED will turn on and the engine will be
shut down. Once the AUTO/OFF/MANUAL switch is
switched to OFF, the individual fault LED will turn off
and the five (5) red LED's will begin flashing to show
that the exercise mode has not yet been setTo test the whole system all you did to do is make sure it is in auto and shut off the utility power to the transfer switch>
