The battery is installed in pointer position 3. The battery receptacle requires a
user-installed CR1220 lithium coin cell battery that provides power to the Real
Time Clock. Installing a battery preserves the Real Time Clock setting in the
event power to the drive is lost or cycled. Approximate battery life is 4.5 years
with drive unpowered, or lifetime if drive is powered. Install the battery with “+”
facing out.
