2.7 Battery Pack Installation & Removal
The battery pack is held into the communicator by two standard 6-32 screws with hexagonal sockets that
require a 7/64” hex key wrench.
To install the battery pack set the communicator enclosure with the display downward on a flat stable
surface. Rest the battery pack in the battery pack compartment of the enclosure leaving a ½” gap between
the battery pack and the connector on the communicator enclosure. Slide the battery pack upward along the
enclosure until the connectors mate completely and the screws are aligned with the threaded inserts on the
communicator body. Thread the screws into the insert to complete the installation.
For disassembly, reverse the order of the operations.
Over-tightening the battery case screws when assembling can cause damage to the communicator.
Maximum torque should not exceed seven in-lb.
Battery should be charged completely (10 hours) before using the communicator the first time. See Section
2.9 for detail on using the charging cradle.
