2General Information
After the S6 PCN and the S6 Power PCN, the S11 is the third model of the new
handset generation for GSM-1800 in 3 Volt technology. Mechanically and technically
it is very similar to the S10.
In addition to the normal S11 another version called S11 E is available which offers
Enhanced Fullrate speech coding to improve the speech quality.
3Mechanical Concept
Note: All part numbers refer to mechanical drawing in section 4.1!
The S11 consists of two boards, the RF & Control module (1000) and the user
interface (1010).
The connection between those two boards is made by a normal connector with plug-
in contacts.
The RF connection from the display module to the RF & Control module is made by
an RF cable (1150) which is soldered onto to RF & Control module, which is covered
by two shieldings (1060, 1050).
The antenna (1130) is directly screwed into the lower case shell.

The keypad (1020), the loudspeaker (1120), the microphone (1110), the dust
protection frame (1190) and the microphone gasket (1220) are mounted into the
upper case shell (1030). Make sure that the microphone contacts are properly bent
up when mounting.
When turning in the screws (1070, 1080) make sure that the right torque is used (25
Ncm), because this will have an effect on the funtionality of the handset.
The only removable part on the user interface is the ringer gasket (1170) which is
needed to increase the ringer volume.

3.4Handset Datecodes
Siemens is using the industrial standard IN EN 60062 to indicate the production /
service dates. The code is printed on the IMEI sticker located under the simcard
reader.

The first character of the datecode indicates the year of production:
F = 1995
H = 1996
J = 1997
K = 1998
The second character indicates the month of production:
1-9 = January to September
O = October
N = November
= ecember
Example: K2 means that the set was produced in february of 1998.
