Step 3. (Option 1CM/Option 1CP). Remove the four bottom feet of the E4990A (lift
the bar marked TAB on the inner side of the foot and slide the foot towards
the bar).
Step 4. (Option 1CM/Option 1CP). Mount the E4990A on the rack.
If the installed front handle becomes damaged, replace it with a new one
immediately. A damaged handle may break while moving or lifting the
instrument and cause personal injury or damage to the instrument.
Use both a front handle and a rack-mounting flange in the same time
certainly. Do not attempt to install flanges or handles separately with
hardware provided. Serious electrical damage will occur to the instrument.
