VIDEOMED DC 6
• Set the camera rotation to the 0° position and mark the position of the VIDEOMED DC
relative to the rotating I.I. optics.
• Switch the system OFF and wait approximately 3 minutes for the anode voltage of the I.I.
mini voltage supply to drop.
• Disconnect the I.I. anode cable from the I.I. mini voltage supply.
• Make sure to short out the residual charge to ground.
• Ensure the correct high tension cable lengths by marking the position of the mounting
cap nut on the anode cable with a colored pencil or electrical tape.
• Remove the O-ring and the cap nut from the anode cable.
• Disconnect the cable from the VIDEOMED DC and the Compact optics.
• Cut the cable ties securing the cable.
• Replace the VIDEOMED DC. Ensure that the VIDEOMED DC is at the 0° position rela-
tive to the rotating I.I. optics.
• Reconnect the VIDEOMED DC - Compact optic cable and secure it with a cable tie.
Make sure that the cable does not protrude past the edge of the board. It must lie in the
recess of the VIDEOMED DC board.
• Reroute the anode cable to the I.I. mini voltage supply.
• Reinstall the cap nut (as marked).
• Reinstall the O-ring.
• The distance from the cap nut to the beginning of the white insulation of the anode cable
should be 70 mm.
• Reconnect the anode cable and secure it.
• Check the camera rotation and adjust it if necessary.
The camera should rotate + 220°+ 3° or - 220° -3° (check this using the display).
• Check the dose rate and adjust it if necessary.
• Check the image sharpness with the IQ Quick test and, if necessary, adjust it at the I.I.
optics.
• Perform the IQ Quick test.
Power supply M14, +5 V / +15 V / -15 V 6
• Replace the power supply.
• Check the power supply voltage and adjust it if necessary. Refer to Chapter 3 of these in-
structions and check the operating voltages.
