4.1 Set Disassembly

4.2 Assembly / Board Removal

4.3 Set Re-assembly

Note: Figures below can deviate slightly from the actual

situation, due to the different set executions.

4.1 Set Disassembly

Follow the disassemble instructions in described order.

4.1.1 Rear Cover Removal

Warning: disconnect the mains power cord before you remove

the rear cover.

1. Remove all the fixation screws of the rear cover.

2. Now, pull the rear cover backwards and remove it.

Figure 4-1 Rear Cover removal

4.2 Assembly / Board Removal

4.2.1 Power Switch and Control Panel removal

1. From the mono carrier disconnect the main power and the

keyboard circuit cables. Release the main power cord and

the keyboard circuit cable from it’s strain reliefs.

2. Then, remove the two fixation screws [1] of the power

switch and control panel and remove the board.

4.2.2 Side I/O Panel removal

Figure 4-3 Side-I/O panel removal

1. Disconnect the side panel cable from the mono carrier and

remove the cable from it’s strain reliefs.

2. Then, remove the two fixation screws [1] and remove the

board.

When defective replace the whole unit.

4.3 Set Re-assembly

To re-assemble the whole set, do all processes in reverse

order.

Be sure that, before the rear cover is mounted:

• The mains cord is positioned correctly in its guiding

brackets (make sure that the strain reliefs are replaced in

its correct position and that it will function correctly!).

• All wires/cables are returned in their original positions.
