I am receiving the error message: Invalid Start Date (33795). How do I fix this?

This is usually due to using old software to communicate with a data logger launched by newer software. This can be fixed by downloading the latest version of MadgeTech software from the MadgeTech website. Invalid start date may also indicate a battery or environmental problem; try restarting the data logger, then stop it to clear out the invalid date. When you start the data logger again and identify it, it will have the correct start date.
