Removing the Rear Panel Assembly
Use the following procedure to remove the rear panel assembly:
1 Remove the shroud (see "Removing the Shroud" on page 3-8).
2 If the Battery Option is not installed, remove the four 4-40 self-locking hex
nuts that attach the battery opening cover to the rear panel (these nuts
are accessible from inside the chassis). Then, remove the battery opening
cover, and skip to step 5.
3 If the Battery Option is installed, remove the battery sled from the
Counter (for instructions on removing the battery sled, see Appendix C
of the Agilent 53150A/151A/152A Operating Guide).

self-locking flathead machine screws that attach the rear panel assembly
to the Battery Option chassis as shown in Figure 3-11 (two screws on each
side of the opening, and two more screws at the bottom of the opening).
