Installation Note E4406-90278 15
Installation Procedure
Step 11. Install the Top Brace and Outer Case 
1. Carefully position the top brace on the deck. Reference the two alignment pins and the two 
alignment holes. Make sure that no coaxial cables will get pinched underneath the brace.
2. Using the T-10 driver, replace the 7 top screws first, and then the 10 side screws after the top 
screws are tightened. Torque to 9 inch pounds.
3. Slide the instrument cover back onto the deck from the rear. The seam on the cover should be on 
the bottom. Be sure the cover seats into the gasket groove in the front frame.
4. Using the T-20 driver, attach the four rear feet with the four screws to the instrument. Torque to 21 
inch pounds.
5. Using the T-20 driver, replace the handles. Torque to 21 inch pounds.
6. Replace the four bottom feet by pressing them into the holes in the case and sliding in the opposite 
direction of the arrows until they click into place. Note that the feet at the front have the tilt stands.
Step 12. Test the front panel keys and knob 
1. Plug in the instrument and turn it on.
2. Wait for the instrument to completely boot up and run through its internal alignment routine.
3. Start the front panel key test by pressing 
Mode, More until (3 of 3), Service, More (1 of 2), Front 
Panel Test
.
4. Test all of the front panel keys by pressing each of the keys (in any order, with the exception of the 
ESC key, which must be pressed last). The first time you press a key a “1” will replace the “0” for 
that row that originally appeared to the right of the key column. (Note: The up and down arrow 
keys are described as the 
Rpg Dn and Rpg Up keys.)
5. Rotate the front panel knob (RPG knob) clockwise and counter-clockwise to test its functionality. 
Rotating the front panel knob will result in a rapidly incrementing or decrementing value 
appearing to the right of the RPG knob entry. 
6. Press the 
ESC key to exit the front panel test.
