Calibrating Batteries
When used under normal operating conditions, where the battery goes
through a cycle of being charged, fully discharged and recharged again,
you should not have to calibrate your Hammerhead batteries.
Periodically, however, batteries may require calibration to improve
accuracy of the battery gauge, particularly if they go through continual
cycles of shallow discharges without ever achieving a fully discharged
state. To ensure that the batteries are operating accurately and at their
best performance levels, we offer a Smart battery charger that will
perform the calibration procedure for you. (DRS Model Number 9800-
17019-0000
)
This Smart battery charger is based on Intel’s System Management Bus
(SMBus) interface for Advanced Configuration and Power Interface
(ACPI). In addition to calibration, the charger can fully charge two
batteries in less time, compared to the current Hammerhead external
battery charger. Typical Charge Time per battery is 1.7 hours.
Note: Only calibrate batteries when they need it. Calibrating a battery
unnecessarily will increase the cycle count and thereby reduce the
battery life.

Removable hard drive
The hard drive compartment allows field upgrades or repairs without
opening the Hammerhead. Some customers may have IT Departments
that will be trained to replace hard drives at the customer location. You
should not open the hard drive compartment without the proper
training from DRS Tactical Systems, Inc. Please contact our technical
support department at 888-872-1100 before removing the cover plate of
the hard drive compartment. Any tampering of the hard drive will result in
a void warranty.
Connectivity
Most often, connectivity with the Hammerhead is via the docking
connector on the backside of the unit. Most customers also purchase a
port replicator, desk dock, or Hammerdock vehicle dock that provides
standard ports for communications, keyboard, and power supply. Port
replicators and docking stations may be customized to your
requirements and may not be configured exactly as described below.
Port replicators
There are several variations of port replicators (flat, angled, custom, etc.)
New connectivity options are constantly in development. The following
features are available on the standard port replicator.
