Mechanical Disassembly/Assembly
The instructions contained here are for disassembly. Re-assembly is performed
by reversing the order of the steps used to disassemble the instrument.
WARNING. Unplug Power Cord:
Before attempting any disassembly of the instrument be sure to disconnect the
power cord.
CAUTION. Rear Panel Screws:
Do not re-insert screws in the rear panel when the instrument is removed from
the cabinet.
NOTE. Screw Types:
All screws, unless otherwise noted, are TORX screws and can be removed with
a T15 screwdriver tip (Tektronix part number 003–0966–00). The exception is
#2 Pozidrive screws which can be removed with a #1 Pozidrive tip
(003–0443–00).
1. Remove the two bezel screws. See Figure 6-3.
2. Grasping the bottom of the bezel, pull straight out and upward. There are
two hinges at the top of the bezel that hold it in place. Once the bezel is at
an approximate 45° angle with the front panel they will disengage.
3. To replace, reverse the procedure.
