Disk Space
Hard disk drive and floppy disk file space can be recovered by
deleting old images that are no longer needed, or those that have
been backed up to an external hard drive, ZIP disk or CD-R. Use
the

option in Windows Explorer for this purpose.
Charging Batteries
It is recommended that unused and spare batteries be recharged
every month while in storage. The Imager and controller batteries
can be recharged by connecting the external power adapters when
they are not in use. There are two different battery chargers for
the DeWalt XR200 battery. One will only work on 110 Vac, 60 Hz,
and the other will only work on 220 Vac/50 Hz. Attempting to use
the battery charger with the wrong AC supply is very likely to
damage the battery charger and possibly the battery. Please
verify compatibility before connecting the charger to a power
source. Batteries should be disconnected from the charging once
they are fully charged.
Charging the Source Battery
The source battery is charged on an external battery charger.
Remove the battery from the source and plug it into the charger
to charge. A fully discharged battery can be charged in
approximately one hour. However, observe the LED indicator on
the charger to monitor battery charging progress. Be sure to
remove the battery when it is fully charged.
Charging the Imager Battery
The battery in the imager can be charged while it is in the imager
unit. Connecting the external power adapter to the Imager,
whether in use or not, will charge the battery. Observe the LED
indicator to monitor battery charging progress.
Imager batteries may also be charged using the external
imager-battery charger provided. The red and green LEDs on the
charger unit will indicate the condition and charge of the battery.
Replacement Integrated Imager batteries must meet or exceed
the specifications for a DR-35S 10.8Vdc 3800 mA/hr battery.
Nickel metal-hydrate (NiMH) is the only acceptable battery type.
Charging the Notebook Controller Battery
The RTR-4 Controller internal battery must remain charged to
ensure that the set is always ready for deployment. Connecting
