5. Unscrew Antenna screw. Use a new
Torx Plus screw and a torque of 26
Ncm for assembly.
6. The Corner Piece fits very tight, so
it needs some extra force to separate
it from the B-cover with the SRT-6.
7. The A-cover is fixed with several
plastic clips. Start with the clip near
to the system connector.
8. Loosen the clips anti-clockwise by
using the SRT-6 as a lever. Do not
twist the SRT-6 because this could
cause damage to the cover.

Re-Assembly Instructions
Assembly of B-Cover Module
1. Assemble the Handsfree Speaker
into the GSM antenna housing mak-
ing sure to apply even pressure
around the circumference of the
device. Ensure the alignment feature
on the device is aligned to the rele-
vant feature in the antenna housing.
Note: Ensure the contacts are
avoided and the speaker gauze is first
fitted to the GSM antenna module.
2. Snap the GSM antenna module
onto the B-Cover module ensuring
the clip nearest the camera window is
engaged first, whilst taking care to
ensure the speaker contacts are
aligned inside the B-Cover aperture
before all clips are assembled to avoid
any damage to them.
Note: The GSM antenna module will
not sit parallel to the B-Cover when it
is assembled. There will be a gap next
to the speaker - this is normal.
3. Fit the camera window gasket/
boot onto the B-Cover moulding
ensuring first that the B-Cover is
internal side up so you can see the
alignment of the gasket with the
three alignment clips into the B-
Cover recesses.
Note: Ensure that the annulus of the
camera boot is concentric with the B-
Cover camera annulus.

4. Turn the B-Cover over once the
boot is aligned and push the boot
retention clips into the recesses in
the B-Cover so they are visible from
the outside of the B-Cover.
5. Assemble the camera window
adhesive to the camera window
annulus on the B-Cover, ensuring it is
centrally fitted and the yellow back-
ing tape is removed.
6. Align the camera window to the
B-Cover using the alignment feature
in both the window and the B-Cover.
Press down on the edges of the win-
dow (taking care not to damage it)
until all three clips snap home to the
B-Cover.
Note: Ensure the B-Cover is supported underneath when the window is assembled. Assembly
force must be at least 60N/cm² for at least 6 seconds.
7. Take an IR window and snap it into
the B-Cover ensuring that it is orien-
tated the correct way around. Assem-
ble the right hand side clip first into
the B-Cover then snap the second
clip into place.
Note: Ensure the front and back of
the window is not cosmetically dam-
aged by wearing soft gloves when
pressure is applied to the window.

into the B-Cover module ensuring the
antenna is engaged under the clip
nearest the battery bay wall before
the external clip is made by pushing
down on the antenna to clip it to the
B-Cover.
Note: Ensure the clips are engaged
by checking the clip is within the clip
aperture of the outside of the B-
Cover. Ensure also that the metalliza-
tion on the antenna is not scratched
or contaminated.
9. Assemble all electromechanical
devices into their specific apertures
provided for them in the B-Cover
module, including the vibra, micro-
phone and DC Jack. Ensure each
device is fully assembled into their
individual cavities and in the correct
orientation as illustration opposite
indicates.
Note: Ensure the contacts on each
device are avoided and the DC Jack
snapped home.

flange with no gap.
Note: Ensure the Class I faces of the
keys are not touched or damaged
during the assembly sequence.
Assembly of UI Module
1. Place the earpiece into the LCD
frame, ensuring the alignment fea-
ture on the device is aligned with the

The PWB must be LED’s up and care
must be taken not to touch the board
to board connector pads.
Note: Ensure the datum pins on the
shield are not deformed.
3. Assemble the LCD module onto the
UI shield assembly, ensuring the clip
at the top & middle of the frame near
the ear piece is assembled first and
then the bottom frame location hole
is assembled over the shield pin.
Note: Ensure the LCD is kept flat at
all times and only ever handled from
the sides. The protective tape must be
kept on the LCD during handling and
assembly.
4. Clip the male LCD connector on
the LCD module into the female LCD
connector on the UI PWB, ensuring to
align the devices first. The connector
should snap into place.
Note: The connector must be assem-
bled keeping it flat and applying even
pressure across the top of the rigi-
diser.

UI PWB, ensuring the alignment pips
on the bottom of the Navi key assem-
bly are located into the holes in the
UI PWB.
Note: Ensure the Class I surfaces of
the Navi key are kept clean and
undamaged. These must be checked
before assembly.
6. Place a lightguide assembly onto
the UI module assembly, sliding the
top right lightguide tab under the
LCD frame first, then clipping the
right then left clips to the engine
shield and finally placing the top left
lightguide alignment hole over the
top left engine shield alignment pin.

distorted and the side clips are fully
assembled and not cracked. Also
ensure that all LED’s are within the
recesses in the lightguide provided for
them.
Assembly of ATO Module
1. Assemble the engine PWB onto
the UI module (making sure the mod-
ule is first placed LCD down). Ensure
the engine is located onto the engine
shield alignment pins.

2. Assemble the camera into the
camera connector using the SRT-11
Camera Assembly tool.
Note: Ensure the alignment pip on
the SRT-11 Camera Assembly tool is
aligned with the pip on the camera
which is in turn aligned with the dot
on the camera connector assembly
before location and assembly. Also
ensure that the camera has all three
clips connected to the shield.
3. Assemble the B-Cover module
onto the UI & PWB modules. Locate
the top of the phone first to avoid
damage to the camera and camera
shield and so the two alignment pins
on the engine shield find their loca-
tion holes in the B-Cover.
Note: Ensure the alignment of the B-
Cover module is correct by aligning it
gently before the clipping of the two
modules. Take extra care as this is a
blind assembly.
4. Clip all three UI module to B-Cover
module clips together ensuring the
top clip is made first followed by the
clip by the system connector and
then finally the clip on the side.
Note: Ensure pressure is only applied

5. Assemble the 7th screw into the
back of the B-Cover making sure not
to damage the B-Cover. This screw
must be a new 5.3mm x 1.6mm T6
(IP6) machine screw (NMP 6150905)
with an orange threadlock patch
applied with a torque of 26 Ncm.
Note: Only use a hand torque driver.
6. Assemble the 6 screws into the
ATO in the order indicated opposite.
Using new 9.0mm x 1.6mm T6 Rem-
form screws (NMP 6150903). A
torque of 19 Ncm must be applied to
these screws when an old B-cover is
re-used and 22 Ncm for a new cover.
Ensure the screws heads are sitting
flush on the lightguide or LCD frame.
Note: Only use a hand torque driver.
Assembly of Transceiver
1. Assemble the A-Cover module
onto the ATO module using the clip-
ping sequence outlined opposite,
ensuring clip number one is slid onto
the lightguide clip (pressure must
only be applied to the edge of the A-
Cover over the clips and NOT over the
LCD).
Note 1: Each of the clips must be
checked for correct assembly in
which case the clip must be fully visi-
ble within the A-Cover aperture.
Make sure the blind clip over the sys-
tem connector (9) is also assembled.

ponent is the correct way around.
4. Assemble the D-Cover module to
the ATO module by firstly removing
the protective tape from the adhesive
at the back of the D-Cover and then
clipping the D-Cover clips to the ATO
in order shown opposite.
Note: Apply light pressure across the
D-Cover once assembled to ensure
the adhesive takes. Ensure gloves are
used and the cosmetic Class I painted
