If you really want to reset the chF alarm manually:

Press and hold the Select button until you get to the historical data.  Tap
the Select button until you get to DSC (days since charged).  Press and hold
Reset until the number resets to 0.

However, the alarm is an warning for a reason.  If inaccurate programming is
causing this problem, fix the programming.  If caused by inadequate charging
capability or too short charge times, "fixing" the problem by resetting the
alarm is like driving your car with duct tape over the gauges to keep from
being annoyed by that pesky low oil light.

Batteries need to be charged to truly full at least once a week.  If the
customer is not achieving this, what is the cause?  Is the charging source
going to float but the meter not resetting?  If so, are the inverter charger
settings adequate?  Or are the TM settings too conservative?  Or is the
customer not allowing the generator to fully charge the batteries (200a
charging into 3500ah = a heck of a lot of genny runtime)

For setpoints for this situation, I would begin with 14.4, 70a, 95-96H, PO1,
3,000-3,500ah, 7dSC, 90dSE, 11bLO.
