•
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 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.

•
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.
Electrical voltage!
See Chapter 1, Safety Information.
Switch the system power supply off and disconnect the power
plug.
