What Happens When I Remove the BIOS (CMOS) Battery?

Issue

My console is being transported via air and the BIOS (CMOS) battery must be removed during transport. 

Explanation

The BIOS (CMOS) battery stores persistent memory for BIOS and the Date/Time/Location settings for your console. Removing this battery and putting it back in will cause these features to reset to defaults. Unless otherwise altered by an end user, the BIOS settings on your console are also the default settings. 

The BIOS (CMOS) battery does not store data for the Show File Archive, however it is highly recommended that the Show File Archive is backed up onto an external drive before the console is transported.  

Replacement Battery

New BIOS (CMOS) batteries can be purchased at your local hardware store. Correct model is: CR2032.
