CSA7404B, TDS7704B, TDS7404B, TDS7254B & TDS7154B Service Manual

6- 17

1.

Remove the left and right covers:

See Figures 6--5 and 6--6, pages 6--18

and 6--19.

H

Trim (all)

Bottom cover

2.

Orient the instrument:

Set the instrument so its rear is on the work surface

and the front of the instrument facing you.

NOTE

. All mounting screw holes are indicated by a star etched around the

mounting hole.

a.

Remove the eleven T-15 Torx screws that secure the covers to the top
and both sides of the chassis.

b.

Remove the twelve T-15 Torx screws that secure the covers to the
bottom of the chassis.

c.

Pull the bottom-right cover down and slide to the right to remove from
the instrument. Pull the top-left cover upward and slide to the left to
remove from the instrument.

CAUTION.

Take care not to bind or snag the covers on the instrument internal

cabling as you remove or install.

3.

Reinstallation:

Do in reverse steps a through c to reinstall the cabinet covers.

When reinstalling the bottom cover, ensure that the cover key enters the key
socket as the cover is put in place. When reinstalling the bottom cover,
ensure that all sides of the covers are snug against the instrument before
installing the screws.
