Operating the VersaDoc
4.1 Starting the VersaDoc System
Both the VersaDoc and the camera module must be connected to the computer prior to
using the VersaDoc system.
To turn on the VersaDoc press the power switch located on the right-hand side of the rear
panel of the instrument. The green LED on the front will illuminate indicating that the
system is ready and to confirm that power is being supplied and all the internal light
modules are functioning properly. The start up initialization process takes approximately 30
seconds. After this time has elapsed the host computer can be turned on. At this time you
can also power up the power supply or CEU if you have a VersaDoc 3000 or 5000 system.
Note: If the LED indicator fails to illuminate and the instrument is inoperative, check that all power cables
are firmly attached and that power is being supplied to the unit. If the unit still remains inoperative or the
VersaDoc acquisition window cannot be opened on the host computer, please contact the Bio-Rad
Technical Service Department for assistance.
The VersaDoc should be switched on at least 30 seconds before the host computer, to
allow for complete initialization. If the VersaDoc is not fully operational before the computer
is turned on, the system will not be recognized as an attached Serial/USB device and the
camera may not be recognized by the digitizing card thus you will not be able to
communicate with the VersaDoc from the Quantity One acquisition window.
For best imaging results it is recommended that the VersaDoc be allowed to warm-up for
10 minutes before use.
