Using the mouse pointer on the UI, click the Work Offline

Step 9. Close the leaf cuvette
Once the RCS program loads the LED light unit will self-
calibrate in a process called “tuning” (see
on page 25). This automatic function begins each user session when a LED light unit is attached.
Close the cuvette to ensure successful tuning of the LED light unit. If you forget to close the cuvette an
error message will appear prompting you to perform the LED tuning manually from the RCS
Utilities
menu. Close the leaf cuvette by pushing down the lever on the top of the cuvette handle.
Step 10. Start CIRAS-2 RCS program on your computer
Launch the PC version of RCS from your computer‟s Start Menu or Desktop shortcut icon. Once you
have established a connection, CIRAS RCS will automatically load default settings and begin LED tuning.
Within several minutes the CIRAS-2 system will come to its normal operating temperature of 55 °C.
During this time you can begin familiarizing yourself with the Parameters Editor and optimizing the CIRAS-
2 system for your needs.
If you see the following Communications Error dialog as the RCS program attempts to establish
communications with CIRAS-2, check that each of the four listed conditions are satisfied. Click on the
Com Port button and select or enter the Com Port number in the CIRAS Com Port field that corresponds
to its assignment in Device Manager (see Step 7 above). There are 99 selectable COM ports.
If your laptop battery is undercharged the following CIRAS-2 RCS error dialog may appear on your
computer screen. You can avoid this by beginning the session with a fully charged battery or by switching
to AC power from a wall outlet.
