3 General Information
The SL10 is he firs Siemens mobile GSM elephone using
he new MCM chipse echnology. I fur her consis s of a
slide mechanism, he so called ProSLIDETM system, which
e.g. suppor s ON-Hook and OFF-hook func ion. As in
S10ac ive, he SL10 also fea ures a real ime clock.
Addi ionally i is equipped wi h an infrared in erface e.g. for
da a ransmission.
Mechanical Concept
Note: All part numbers refer to mechanical drawing in section 4 1! These numbers are not
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 consis s of wo major par s: The slide uni and he base uni . User in erface
compared o o her Siemens mobiles is no realised by jus one MMI board con aining all
necessary componen s, bu is separa ed in o a MMI board (1010) inside he slide uni which
carries display and a par of he keypad (1250), and a second keypad (1240) inside of he base
uni . Microphone (1200) also is loca ed in he base uni .
The connec ion be ween MMI board and RF&Con rol board is no es ablished by a normal
connec or wi h plug-in con ac s or an in erconnec or (e.g. like in S6), bu by a flexible cable.
The same kind of cable is used o connec he keypad (1240) and microphone (1200) inside of
he base uni o he RF&Con rol board (1000). The one end of hese cables is soldered o he
appropria e board, he o her end is plugged in o a ZIF-connec or (ZIF= Zero Inser ion Force).
Attention:
The flexible cables are very sensi ive o any kind of mechanical mis rea men . Please be
careful no o damage hem during he repair process of he elephone! Various kinds of
failures can come up even if hese cables are only bended.
The shielding concep is similar o he one of S6. The upper case (1040) of he base uni is
coa ed wi h a conduc ive ma erial and conduc ive rubber. This es ablishes he shielding of he
one side of RF&Con rol module (1010). On he opposi e side of his board here is a shielding
screen (1160) above he relevan area, which is fixed by four screws (1280). The an enna
(1230) is direc ly screwed in o he lower case (1050) of he base uni .
The keypad (1240), he loudspeaker (1220), dus pro ec ion frame (1070) and MMI board
(1010) are moun ed in o he upper case (1020) of he slide uni . Please make sure while
assembling he slide uni ha he me al con ac s of he dus pro ec ion frame (1070) are
properly ben up when moun ing.
When urning in he screws (1270, 1280, 1290) make sure ha he righ orque is used
(1280, 1290: (0,08+0,02)Nm; 1270: (0.2+0,05)Nm).

5.2 Hardware Description
The handse consis s of five major in egra ed circui s. Some of hem - beside o hers - are
in egra ed in o jus one single IC, he so called Multi Chip Module (MCM)
1) HiGOLD PMB 2800 (inside MCM)
This IC is a combina ion of microprocessor and signalprocessor.
The microprocessor is responsible for con rolling he keyboard, SIM-Card, EEPROM, Flash
and RAM.
Fur hermore i con rols he power up/power down of he RF module and se s he amplifica ion
of he PA.
The signal processor is responsible for processing he Rx I/Q signals (fil ering, equalizing,
speech and channel decoding).
Fur hermore i does he speech and channel encoding and he GSMK modula ion of he Tx
I/Q signals.
3) GAIM PMB 2905 (inside MCM)
The GAIM provides he in erface be ween he analogue signals (I/Q, voiceband, PA-con rol)
and i s digi al represen a ion.
4) Receiver Circui (PMB 2409)
This circui provides he following main func ionali ies:
Low Noise Amplifier (LNA) wi h a fixed amplifica ion of +20dB o amplify he
inpu RF signal.
Mixer o mix down he RF signal o he In ermedia e Frequency (IF)
Programmable IF amplifier wi h a dynamic range of 60dB ( -10dB o +50dB in
s eps of 2dB)
Mixer o mix down he IF signal o he baseband, genera ing and inphase (I) and a
quadra ure (Q) signal.
Offse compensa ion for he I/Q signals.
5) Transmi er Circui PMB 2240/45
This circui provides he IF syn hesizer, he I/Q modula or, prescalers o regula e he RF
syn hesizer and a buffer s age o feed he PA.

5.3 Power Supply Concept
The SL10 has wo main power inpu s (see blockdiagram):
1) Ba ery Vol age (3.6 Vol s) connec ed a he ba ery con ac s
2) Charging Vol age (6.5 Vol s) delivered by he desk op charger (using he charging con ac s
a he bo om of he phone)
Since he ba ery vol age is supplying he power supply asic, i is a mus o have he ba ery
(or service adap er) inser ed o opera e he phone.
You cannot switch on the handset if the battery voltage is not present.
From he 3.6V ba ery vol age, all o her supply vol ages of he SL10 are derived, con rolled
by he power supply ASIC.
The RF module needs 6.0V for i s PA: This vol age is genera ed by a s ep-up conver er.
The logic module, MMI and IrDA circui use 2.8V, genera ed by a linear regula or inside he
ASIC. The opera ing vol age for he display illumina ion (100Vpk) is derived from his 2.8V
also.
Fur hermore he ASIC genera es he supply vol age for he Chip-card and he supply vol age
for he Flash.

Mobile Phones
Service Manual SL10 V1.1 PN MP ST
R. Fleuren
sm_sl10_lvl2_v11.doc Page 17 of 22 05/98
The ASIC also checks he presence of he wa chdog signal from he µP and provides he
swi ching on-func ionali y (ON/OFF bu on or imer signal).
The 2.8V power supply of TCXO, Receiver and Modula or is derived direc ly from he
ba ery vol age by a separa e linear regula or.
During es ing is is advisable o use he service adap er, connec ed o a power supply
delivering +4V, max 3A. Make sure ha you connec he service adap er wi h he righ
polari y, he red plug o +4V and he blue plug o ground.
CAUTION!
If you use a voltage higher than +7V, or with wrong polarity, the phone can e destroyed!
5.4 Limits of Voltage and Current
a) Battery Voltage:
If he ba ery vol ages rises above 6.2 Vol s, he phone will swi ch off and i canno be
swi ched on again before he vol age is lower han 6.2 Vol s.
If he ba ery vol age rises above 7 Vol s he phone can be des royed.
b) Charging Current:
The charging curren mus no rise above 1 A or he phone (fuse) will be inoperable.
Be careful wi h foreign accessories or chargers!
Make sure ha he charging curren is limi ed o a value below 1A!

6 Battery
6.1 Specification
The SL10 ba ery is a Li hium-Ion ype wi h a vol age of
3.6 Vol s and a capaci y of 550mAh.
The connec ions BATT+ and GND are used o supply he
mobile, while RCODE is used o de ec he ba ery
echnology. BATT_TEMP is used o measure he ba ery
empera ure.
Charging he ba ery can be impossible, if he empera ure of he ba ery cells is oo high (e.g.
in car use during summer) or oo low. This is o preven he ba ery from being damaged
during fas charge process. To enable he charging process again, he ba ery only needs o
cool down/warm up. A replacemen of ba ery is no necessary.
6.2 Short Circuit Protection
The ba ery is shor -circui pro ec ed by an elec ronic fuse.
The rese ing of he fuse can be done by he following procedures:
Plug he ba ery in o he desk op charger.
or
Apply +5 Vol s be ween he BATT+ and GND con ac s (see drawing!)
Caution! Limi he curren o 10mA.
6.3 Deep Discharge
If he ba ery is deeply discharged i can be recharged by he following procedure:
• Inser fla ba ery in o handse and connec ravel charger. The charging symbol
will no be visible. Wai for appr. 1 hour and disconnec charger af erwards.

symbol mus be visible on he handse display.
6.4 attery Datecodes
The da ecode prin ed on he ba ery will give you he following informa ion:
Example: TOS 8 G9 VA 1
TOS = Ba ery cells supplied by Toshiba
8 = Revision level
G9 = Datecode (see below)
VA = Var a (ba ery manufac urer)
1 = Place of manufac uring (1=Germany ,2= Novibor, Czech Republic)
Datecode:
Charac er 1: Year of produc ion (J= 1997, K= 1998)
Charac er 2: Mon h of produc ion
(1-9 means January o Sep ember; O=Oc ober; N=November ;
D=December)
Example: TOS 8 K4 VA 1 This ba ery was produced in april of 1998!
