1. Specifications

C. Push down the corners of the PCB until all 4

adapter bracket snaps (not shown) engage.

Make sure that the J5 connector pins are

completely inserted into the mating connector

housing.

D. Plug in the flat, 16-pin cable (13) to the PCB.

E. Secure the PCB to the adapter bracket with 3

screws (6).

F. Place the connector gasket (7) over the

connector panel.

5. Adapter Bracket and Heatsink Removal

NOTE: It is only necessary to remove 3 screws

(10) to remove the adapter bracket (8). These

screws are located on the same side as the

module's labels. The bracket hooks onto a flange

that is part of the heatsink (9). If further

disassembly of the unit is required, then all 6

screws (10) should be removed.

A. Remove 6 screws (10) that secure the adapter

bracket and the heatsink to the module.

B. Pull the bracket and heatsink away from the

module.

NOTE: The Amplifier PCB Assembly (11) may be

stuck to the heatsink with thermal grease.

6. Adapter Bracket and Heatsink Replacement

A. Lower the heatsink (9) into position on top of

the Amplifier PCB (11). Make sure that the side

of the heatsink with smaller fins is aligned with

the module's label side.

B. Align the screw holes on the heatsink with

those on the transformer cup (19).

C. Hook the adapter bracket (8) onto the heatsink

flange. Lower the adapter bracket into position.

The bracket has screw holes only on one side.

These should be aligned with the screw holes on

the module's label side.

D. Secure the heatsink and adapter bracket to

the module with 6 screws (10).

7. Amplifier PCB Assembly Removal

NOTE: It is not necessary to completely

disassemble the unit to access the Amplifier PCB

(11). Follow the simplified steps A-D below if

direct access to this PCB is required and you

have not already disassembled the unit.

A. Remove the cover (3) using Procedure 1.

B. Unplug the flat 16-pin cable (13) connecting

the Main PCB to the Amplifier PCB.

C. Remove 6 screws (10) that secure the adapter

bracket (8) and heatsink (9) to the module.

D. Lift the Main PCB (5), adapter bracket and

heatsink away from the module.

NOTE: The Main PCB should remain connected

to the transformer primary side. It should also

remain secured to the adapter bracket with 3

screws (6).

E. Lift up the Amplifier PCB (11) and unhook

connectors J1 and J4 from the PCB. J4 is

connected to the woofer and J1 is connected

to the transformer assembly's (18) secondary

side. Pull the PCB away from the unit.

F. Remove the two transistor spring clips (14)

that rest on the transformer cup (19).

8. Amplifier PCB Assembly Replacement

A. Place the two transistor spring clips (14) on

the transformer cup (19).

B. Connect the J4 connector to the safety-

controlled woofer cable (24) and connector J1 (5

pin) to the transformer assembly's (18)

secondary side. When facing the module's label

side, the transformer's secondary side is on the

right.

NOTE: The large capacitors on the Amplifier

PCB (11) fit into one side of the transformer cup

(19).
