Quad Charger
The Quad Charger is designed to simultaneously charge four Battery
Packs. It may be mounted on a horizontal or vertical surface.
The Battery Pack snaps into the charging slot. The LED above the
occupied bay indicates the charging status of the Battery Pack in the
bay.
A flashing LED may indicate a Battery Pack failure. Verify the
condition of the Battery Pack by the following procedure before
replacing it. First check the Battery Pack in a different bay or
substitute another charger and repeat the operation that caused the
failure. If the same Battery Pack lights a steady LED when inserted
in a different bay or charger, the first charger may be faulty. Contact
your system administrator for service information.
