2.3.3  Memory PCB Board 

Disassembly 

1. Remove the Battery Pack. (See section 2.3.1 Disassembly)
2. Remove the Rear Cover. (See section 2.3.2 Disassembly)
3. Slight lift up the “Memory PCB Board” from the “PDA Memory PCB Board connector”. (Figure 2-6)
4. Now you can separated the Memory PCB Board from the PDA. (Figure 2-7)

Reassembly

1. Carefully connect the memory PCB Board back to the PDA M/B. (Figure 2-6)
2. Reassembly the Rear Cover. (See section 2.3.2 Reassembly)
3. Reassembly the Battery Pack. (See section 2.3.1 Reassembly)

Figure 2-6  Lift up the Memory PCB Board
