Honestly, I think Recalibration Mode is activated after a certain amount of years (example: Five years after the original series), it recalibrates the first five years after the Omnitrix is obtained and will recalibrate every five years until said Omnitrix is deactivated or destroyed.

OR...

Azmuth is able to know what Ben and co. are doing through the Omnitrix, so there's no way he shouldn't be able to send recalibration updates from Galvan Prime to the Omnitrix.
