Disassembling the Universal
Header Subassembly

Note: The next step requires the use of both hands. Do not
push on the purple pocket eject button (27), since this
will prevent the pocket from latching in place. Do not
apply excessive force on the kicker (4) as this may
cause permanent damage to the kicker spring (3).
8. While pressing inward on the pocket lid housing (26), rotate the
kicker lever (4) at the end of the pocket by deflecting the kicker
arm until the pocket is free to move. Continue to push on the
pocket actuator until the pocket latches.
Note: If the reason for disassembly is to use the NTN8982_
Troubleshooting Kit, skip the steps below and proceed
to the "XTVA Troubleshooting Kit Procedure" on
page 36 for appropriate instructions.
9. Remove the RF connector (part of 31) from the chassis (8) by
lifting it out of the chassis. This may require slight rocking of the
connector to dislodge it. Make sure to apply force to the
connector body only and not to the crimped cable connection or
the cable itself. Do not pull on the cable.

While performing the next step, make sure not to pull on
the flex circuit ribbon cable.

10. The universal coax subassembly (31) is now exposed. Gently twist
(in a clockwise direction) and pull outward on the header until it
clears the pocket lid housing (26). Then, pull the entire assembly
upward, being careful not to pull on the flex circuit ribbon cable.
Set the subassembly next to the unit.
11. Gently lift the chassis subassembly (8) away from the back
housing (14), and set it on a flat working surface for further
disassembly.
12. Gently press the purple pocket eject button (27) to disengage the
pocket housing (5), and guide it out of the chassis. The eject
spring (10) will fall off during this step. Set the pocket housing
subassembly aside.
13. A contact insulator is located on the back side of the chassis,
above the rectangular opening, and is attached to the chassis with
adhesive. The insulator may be removed with a flat-head
screwdriver, but this should not be done unless replacement is
intended.
14. Referring to Figure 8, gently lift up the opening frame on the ZIF
flex circuit connector, located on the PC board assembly (11), and
slide the flex circuit ribbon out of the connector.
15. If necessary for replacement, remove the link (2) from the
universal subassembly by twisting the link and prying it out of
the float bracket holes.
16. The universal header assembly should not be disassembled any
further.
