CC640 Digital Camera
9.1 Lithium Battery
The Camera is equipped with a Lithium Thionyl Chloride Battery. The battery
maintains the clock functionality for periods when power is not connected to
the camera. The expected battery life is 2 years. If the camera is in operation
and connected to a power supply, the battery life may be extended up to 10
Years.
It is recommended that the battery be replaced by a certified repair facility.
The sticker on the bottom of the camera indicates the date of battery
installation.
9.2 Lens Cleaning
If the filter or lens requires cleaning, it is very important that only a proper lens
cloth (like those included with your CC640 camera) or lens tissue be used. The
use of inappropriate materials to clean the lens can permanently damage or
reduce the effectiveness of the filter or lens.
10. Setup and Interface Guide
10.1 Trigger Mode
Determine how the camera will be triggered to initiate an image acquisition.
There are 2 different trigger sources. The first is using the external trigger
input and the second is self-timed mode, which uses the cameras own real time
clock. A combination of external trigger and self-timed mode can be used also.
10.1.1 External Trigger
If the camera is being triggered by an external signal provided by another
device then:
• Set the parameter Self-Timed Interval to zero
• Connect the external signal to the Ext input of the camera
10.1.2 Self-Timed Trigger
A camera that is used in self-timed mode should be set up as follows:
• Set the parameter Self-Timed Interval to a non zero value
• Change the Start Minute and Stop Minute values accordingly
• Leave the Ext input of the camera unconnected or connected to ground
10.1.3 Combination of External and Self-Timed Triggers
A camera that is used in this configuration should be set up as follows:
• Set the parameter Self-Timed Interval to an non zero value
• Change the Start Minute and Stop Minute values accordingly
• Connect the external signal to the Ext input of the camera
