With the C1x (C10, C11 and C12) the first series of the new C class of Siemens
Mobiles are offered to the customer. The intention of this class is to offer entry-level
mobile phones for the mass consumer market.
One of the main differences is the new type of display used: It is an alphanumeric
display which offers 3 lines of text (12 characters
each) plus a dedicated icon-line to access the
different menues.

Mechanical Concept
Note: All part numbers refer to mechanical drawing in section
4.1!
The mechanical concept of the C1x mobiles is similar to the one of S6 and E10.
The C1x consists of two boards, the RF & Control module (1000) and the user
interface (MMI board, 1010).
The connection between these two boards is not established by a normal connector
with plug-in contacts, but by a special interconnector (1210) embedded into a
shielding frame (1080). This interconnector is upholding the connection through the
pressure implied on it by the housing.
Caution:
Be careful when assembling the interconnector. Avoid any kind of dust or
dirt because it will affect the contacts of the interconnector.
On the MMI board there are no exchangeable components. In opposite to the MMI
board of S6 and E10 there is no ringer on the MMI. The ringer (1220) is placed in the
shielding cover (1090) and connected to the RF&Control module (1000) by a plug
and a cable.
Because the Molex connector is not located at the bottom of the telephone but on it’s
top, there is no need anymore for RF cable mounted to the MMI board and for a RF
plug neither.
The antenna (1150) is not screwed into the lower case shell, but it is a plug-in type.
The keypad (1050), the loudspeaker (1140), the microphone (1130), the dust
protection frame (1070) and the display window (1060) are mounted into the upper
case shell (1020). Make sure that the microphone contact springs are not damaged
when mounting.
When turning in the screws (1160 and 1170) make sure that the right torque is used
(0.25
0.05)Nm, because this will have an effect on the contacts of the
interconnector.
