The AFX100/AFX210's built-in battery has a designed lifespan of over 15 years when no power is applied, so there is no need to replace it under normal use.
When the battery runs out, the real-time clock's date and time information can no longer be retained, and all timestamps when saving logs are saved as 2000/01/01 0:00:00.
The battery cannot be replaced by the customer. Replacement will be available for maintanance service , so please contact our support.
