output cables from it and remove the unit from the rack. If
the scaler is not rack mounted, you do not need to remove
the input and output cables.

card at an angle with the audio connector protruding
through the rear audio connector opening.

3. The audio card has a 20-pin socket on the underside that
must align with the 20 pins on the main circuit board. Be
sure to align the pins properly, in order to prevent bending
the pins, before pressing the audio card firmly in place
against the standoffs. The four mounting holes on the audio
card should now be directly over the standoffs.

4. Remove the cover by slightly lifting each side alternately
until the cover is free.

Reverse this procedure to reinstall the cover after the audio card
has been installed.

CAUTION

Do not touch any switches or other electronic
components inside the scaler. Doing so could damage
the scaler. Electrostatic discharge (ESD) can damage
IC chips even though you cannot feel it. You must be
electrically grounded. A grounding wrist strap is
recommended.
