4.4 Storing
Store the equipment in the O state with a fully charged external battery installed. The
external battery always provides power to some system components even when the sys-
tem is in the O state. If the system is stored with the external battery removed, these
components are powered by the system’s internal battery. The internal battery is not de-
signed for extended use and will discharge in a short period of time; this could result in
damage to the internal battery. You can store the equipment in the O state for about 30
days with a fully charged external battery installed. Aer this period, the external battery
pack should be recharged or replaced with a charged external battery.
