Cingular IV Digital Camera User Manual


 
Appendix C - Power Supply Considerations and Power Switch Settings
The camera can be powered externally with an AC adapter or internally via 5 AA batteries.
Internal batteries
Remove the four machine screws holding the bottom plate to access this area. When internal
batteries are used, the switch on the battery tray must be in the upward (towards the red dot)
position. Make sure the batteries are installed with the correct polarity, the flat end of the battery
(negative) faces the spring within the holder.
The duration of operation obtained from a single set of batteries depends on several factors; the
operating mode selected, the image size and compression level, the type of battery, the
temperature, and the rate of image delivery. The following table depicts typical performance for
different battery types when the camera is configured to deliver 1 image every 15 minutes. The
images are Large size with Medium compression setting, and the camera is operating in the Auto
mode at room temperature.
Battery Type Images Delivered
Alkaline 350
Rechargeable 325
NiMH
Lithium 650
External power
An AC adapter is available which will supply power to the external connector. When the external
power connections are used, the internal power selector switch must be set properly (away from
the red dot), and no batteries need be installed. The external power requirements are listed in the
Appendix B.
Power mode selection
Two power modes are available when operating the camera. The power switch on the back panel
selects these modes. The ON mode keeps the camera constantly powered. The AUTO mode
allows the camera to turn on only in response to a scheduled time or to a signal on the external
trigger. The only operational difference between the two modes is that in the ON mode the
camera can receive and respond to text messages from a cell phone. Since the camera is off most
of the time in the AUTO mode, this capability is not available. However, the AUTO mode is
useful for minimizing power usage, an important feature for remote operation.
Generally, the availability of external electric power at the remote location will determine the
power mode, ON or AUTO, in which the camera will be operated. The camera operation and
required settings associated with the two modes is summarized in the following table
