valid for ordering spare parts. For appropriate ordering numbers please refer to the official
spare part list. If you have questions regarding spare parts, please contact your service
manager.
The SL10 consists of two major parts: The slide unit and the base unit. User interface
compared to other Siemens mobiles is not realised by just one MMI board containing all
necessary components, but is separated into a MMI board (1010) inside the slide unit which
carries display and a part of the keypad (1250), and a second keypad (1240) inside of the base
unit. Microphone (1200) also is located in the base unit.
The connection between MMI board and RF&Control board is not established by a normal
connector with plug-in contacts or an interconnector (e.g. like in S6), but by a flexible cable.
The same kind of cable is used to connect the keypad (1240) and microphone (1200) inside of
the base unit to the RF&Control board (1000). The one end of these cables is soldered to the
appropriate board, the other end is plugged into a ZIF-connector (ZIF= Zero Insertion Force).
Attention:
The flexible cables are very sensitive to any kind of mechanical mistreatment. Please be
careful not to damage them during the repair process of the telephone! Various kinds of
failures can come up even if these cables are only bended.
The shielding concept is similar to the one of S6. The upper case (1040) of the base unit is
coated with a conductive material and conductive rubber. This establishes the shielding of the
one side of RF&Control module (1010). On the opposite side of this board there is a shielding
screen (1160) above the relevant area, which is fixed by four screws (1280). The antenna
(1230) is directly screwed into the lower case (1050) of the base unit.
The keypad (1240), the loudspeaker (1220), dust protection frame (1070) and MMI board
(1010) are mounted into the upper case (1020) of the slide unit. Please make sure while
assembling the slide unit that the metal contacts of the dust protection frame (1070) are
properly bent up when mounting.
When turning in the screws (1270, 1280, 1290) make sure that the right torque is used
(1280, 1290: (0,08+0,02)Nm; 1270: (0.2+0,05)Nm).

The SL10 is the first Siemens mobile GSM telephone using
the new MCM chipset technology. It further consists of a
slide mechanism, the so called ProSLIDE
e.g. supports ON-Hook and OFF-hook function. As in
S10active, the SL10 also features a real time clock.
Additionally it is equipped with an infrared interface e.g. for
data transmission.
