You may verify the hand calibration by performing the following homing procedure. Note : After the analog clock firmware has been successfully updated it is suggested to perform the following procedure.
Note: If the clock is not installed in a permanent location or if the clock can be easily removed then perform the Homing procedure. However, if the rear of the clock cannot easily be accessed, then skip the homing procedure and proceed to the hand calibration procedure.
Homing Procedure:
Note: The Red LED status indicator on the face of the clock should flash ON and OFF once per second.
If the clock hands are at the 12:00:00 position (+/- one half of a second tick mark), then the hands are properly calibrated.
The following three images show the clock homed with proper hand calibration.
Note: If the clock hands are not at the 12:00:00 (+/- one half of a second) position it is necessary to recalibrate the clock hands.
