operatIon
The XP2i can be operated from the adapter without batteries installed, although we recommend that batteries remain in the XP2i. The batteries will act as an
automatic backup supply in case of power failure.
To protect the XP2i from power supply failures, or connection of non-approved DC power supplies, the pass-through connector includes a non-serviceable fuse.
