17. Pack the old power supply in the new supply’s shipping container, and return it to Ross
Video Technical Support . The supply will be inspected to determine the cause of the
failure.
18. Verify all connections. It is not necessary to remove the labels from the ten power supply
cables.
19. Re-connect all AC power cords and turn on the control panel power.
This completes the procedure for replacing a control panel power supply. Next, you can calibrate the
power supply voltages.
Calibrating the Control Panel Power Supply
Although each control panel power supply is calibrated at the factory, it is highly recommended that
you check the supply’s voltages and re-calibrate the supply (if required) — once it has been installed
in the control panel.
Use the following procedure to check and calibrate the control panel power supply:
1. Ensure that you have access to a digital voltmeter.
2. Ensure that only the newly installed power supply (or the one that you want to test) is
turned on. If both power supplies are installed and turned on, turn the old one (or the one
that you do not want to test) off. This step ensures that correct voltages will be measured.
3. If the top of the control panel is up, lower it momentarily in order to place the panel in
the “ Lamp Test ” mode. This diagnostic mode ensures that a suitable load is placed on
the power supply.
4. Navigate to Lamp Test Menu as follows:
• Press HOME (to display the Main Menu 1-2 ).
• MORE (to display the Main Menu 2-2 ).
• Setup (to display the Setup Menu ).
• Panel Diagnostics (to display the Panel Diagnostics Menu ).
• Lamp Test (to display the Lamp Test Menu ).

5. Press any button in the Pattern Control Group — to light all of the buttons in the
group. Leave the system in “ Lamp Test ” mode for now.
6. Raise the cover of the Synergy control panel to access the Panel CPU circuit board.
Note Do not lower and secure the control panel cover until you have
completed the calibration procedure.
