SECTION 2

DISASSEMBLY

IMPORTANT NOTES :

1) Disassembly of the RF/Logic Assembly, including the Lower Shield (on which the IMEI sticker is mounted) and all other shielded elements attempt to do so may lead to non-compliance with GSM as well as CE specifications, and in extreme cases it can cause interference problems.

2) When replacing cosmetic parts, verify if all spacers are mounted on the new cosmetic; if necessary transplant them from the old to the new cosmetic part.

3) When reassembling, make sure all screws are tightened fully.

• Remove the SIM Card Holder (1).

• Remove the Antenna (2) using the Antenna Jig; also remove the Antenna Ring (3) which is pressed over the

top/bottom cosmetic part. Note the position (top/down side) of this ring for correct reassembly.

• Remove the Battery Lid (4) and the Battery (5).

• Unscrew four screws (a) on the Battery Compartment.

• The Lower Case Assy (6) can now be lifted; however, it is still tightened as the top side is held together with

claws. Lifting the Lower Case Assy is preferrably performed gently on the antenna side. When reassembling this

•

part, first insert the REC/PLAY button side.

• The RF/Logic Board (7) along with the Microphone Arm Assy (8) can now be taken out. Note, however, that

the RF/Logic Board is still held onto the Display Board through a connector located at the bottom/left side between the two boards, so at this point still invisible.

• To remove the RF/Logic Assy (7), including the Microphone Arm Assy (8), first of all put the Microphone Assy

to an angle of 90° versus the set. Next, push the Microphone Assy gently upward while at the same time pushing the Microphone Holding Part of the Upper Housing Assy downward (b). This should release the RF/Logic Assy from the rest of the set.

• The Microphone Arm Assy can be released by unscrewing one screw (d).

• When reassembling this board, gently push in the bottom/left corner to insert the RF/Logic side connector

into the display connector side.

• When disassembling the RF/Logic Board, three Plastic Sleeves (10) will come loose; note their position for

correct reassembly.

• The Display Board (11) can now be taken out of the Upper Housing Assy (12).

• The Jog Mounted PCB (13) can be taken out of the Lower Case Assy after unscrewing four screws (c). Note

that one of these screws has a large head.

• Underneath the Jog there is a Jog Shielding (14).
