Initially calibrate after 1,200 operating hours, then once a year or
after 4,000 operating hours, whichever comes first. The initial
calibration should not occur before 720 hours of use. If the initial
calibration is done before 720 hours of use, the module will reset
to require its next calibration after 1200 hours, instead of after
4000 hours.
