This setting is reserved for future use.
Memory Test: Off
The Memory Test validates that the memory is working okay. It takes
longer to boot up the Allegro when it is on, so it is best to only turn it
on occasionally and leave it off most of the time.

This fi eld displays the current setting for battery capacity in
milliamp-hours. This setting effects the gauging circuitry and
should be set to accurately refl ect the capacity rating of the NiMH
rechargeable battery pack in use. It can only be set in the popup
window that is invoked when the battery is replaced. Refer to
Chapter 2, Hardware Features, Batteries for details.
