it needs some extra force to separate
it from the B-cover with the SRT-6.

plastic clips. Start with the clip near
to the system connector.
8. Loosen the clips anti-clockwise by

Re-Assembly Instructions
Assembly of B-Cover Module
1 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 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 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.

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.
6 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
