Installing and Replacing the Battery Pack

Your Smart Device uses two types of battery: a battery pack and a memory backup battery.
The battery pack is used to power normal operations and to store data, while the memory
backup battery provides the power required to maintain memory contents when the battery
pack power is unable to supply power for some reason.
You can choose either battery pack (HA-R20BAT) or large-capacity battery pack
(HA-R21LBAT) for operating power.
The backup battery is installed inside of the Smart Device.
This guide uses the following terms to refer to the batteries.

battery pack.
You can charge the battery pack using the AC adapter, four-bay battery charger, four-cradle
battery charger, USB cradle, or LAN cradle. See the relevant sections in this guide for the
