DISASSEMBLY/ASSEMBLY PROCEDURES
Figure 1. Locking Tab Screw Location
Note: Refer to the Figures (2 and 3) for the
following procedures.
1. Top Cover Removal
1.1 Remove the four screws (two located
at the rear of the unit and one located on
each side of the unit) that secure the top
cover to the chassis.
1.2 Lift the rear of the top cover slightly
and slide it forward until the front of the top
cover is clear of the switches.
2. Top Cover Replacement
2.1 Align the front of the top cover with the
switches and LED's and slide the cover into
place.
2.2 Secure the top cover into place.
3. 302EQ ("piggy-back") PCB Removal
Note: The original 802C has two PCB's.
The following procedure will discuss the
removal of the "piggy-back" PCB.
Note: The "piggy-back" PCB does not
need to be removed when removing the
main PCB.
3.1 Perform procedure 1.
3.2 Locate the four plastic stand-offs (three
are located in the corners of the PCB and
one is located between C125 and C225).
3.3 With small needle-nose pliers, squeeze
the retaining tab of each stand-off while
gently lifting up on the PCB to release the
lock. Grasp the PCB at the middle of each
side and lift the PCB off of the connectors.
5.5 Lift the front of the PCB up slightly.
Gently pull the PCB out while pushing on
the center of the XLR jacks.
6. Main PCB Replacement
6.1 Carefully slide the PCB into the chas-
sis while aligning the XLR jacks into their
housing.
6.2 Lock the XLR jacks into place by
inserting a small screwdriver into the small
hole in the XLR jack and rotate the screw
clockwise 1/8 turn.
6.3 Replace the 5 screws that hold the
PCB into place in the chassis.
6.4 Perform procedure 2.
4.2 Perform procedure 2.
5. Main PCB Removal
5.1 Perform procedure 1.
5.2 Remove the 6 knurled nuts securing
the input and output jacks to the chassis.
5.3 Remove the 5 screws that secure the
main PCB to the chassis.
5.4 On the rear of the unit, at the XLR
jacks there is a small hole with a locking
screw inside (see Figure 1). Insert a small
flathead screwdriver into the hole and
rotate the locking screw 1/8 turn counter-
clockwise to release the locking tab.
4. 302EQ ("piggy-back") PCB Replace-
ment
4.1 Replace the "piggy-back" PCB (on the
original 802C controller) by placing the
board over the connectors and pushing the
board down onto the stand-offs.
