3.1.3.3. MB & Touch Controller Assembly

Refer to Fig. 3-4. Follow the steps below to assemble the

motherboard to the system chassis. Make sure the CPU with

cooling fan and SDRAM are already properly installed to the

motherboard before the motherboard is attached to the

display metal plate.

1. Reverse the display module with the rectangle openings at

the right bottom side. From your point of view, the

motherboard module is to be installed to the right upper

side of the metal plate.

2. Tape the motherboard insulator to the motherboard (C)

first. The insulator is to separate the electronic

components on the reverse side of the motherboard from

the metal plate to prevent short circuitry caused during

system operation.

3. Fix the motherboard with an insulator to the chassis with

nine PMS M3*6 screws.

4. Fix the touchscreen controller (D) to the lower side of the

metal plate with four PMS M3*5 screws.
