Replacing the coin-cell battery
Attention: Do not open your storage product or attempt any repair before reading and understanding “Safety

Your storage product has a special type of memory that maintains the date, time, and configuration
information for built-in features. The coin-cell battery keeps the information active when you turn off the

including passwords, are lost and an error message is displayed when you turn on the storage product.
