Battery Power
A 10.8Vdc rechargeable battery is located in the hinged
compartment below the keyboard of the controller. A fully
charged battery allows about 60 minutes of continuous operation.
The battery in the controller automatically begins recharging as
soon as the unit is plugged into a line power outlet, and takes
approximately eight hours to completely recharge. The controller
does not need to be powered up for recharge, but it does need to be
connected to a standard line power source.
An optional external battery charger can charge optional spare
batteries. Fully recharging a discharged battery with an external
charger takes about three hours.
A red LED on the CU-4 controller display panel will begin to flash
when battery power is low. When this occurs, images should be
saved and the system should be shut down as soon as possible, or
the controller should be connected to a standard line power
source.
