Operation Using 8008 CDU
The 8008 CDU is of ABS construction with graphics LCD and backlight, membrane keys and integral battery
compartment. The unit is sealed to IP67 (10 seconds at 0.3 metres).
The 8008 CDU is designed to allow real time display of data from an underwater unit, and to enable the
setting of parameters for a Model 106. It is possible to connect the 8008 to a printer for a permanent record
of the data, and it has an optional logging facility of its own. However, this does not allow uploading of
logged data from the memory of the fish; a PC is required for this function.
CDU express is software supplied on a CD with the 8008 unit to allow for easy extraction of logged data
from the 8008 to a PC. Please refer to the CDU express manual for details on operation
4.1.
