3 General Information
With the S25/S2588 is the first dual band, E-GSM and triple rate telephone of the
S-class of Siemens mobiles. The target consumer group of this class is the High-End
customer who requires an attractive telephone capable of high operating times and
equipped with an advanced set of features.
This telephone is a so called Dual band telephone, meaning it is capable of
operating in GSM 00 networks as well as in GSM 1800 ones.
The S2588 is a special version of S25, which is designed for the asian market. The
only difference between S25 and S2588 except the name is the different software
inside.
The software of S2588 supports presentation of
chinese characters on the display, the S25 software
does not.
The mobile offers professional features to the customer, of which some are available
for the very first time in a Siemens phone. Specific features are not available in every
model of S25. The decision is taken by the relevant customer (network operator,
service provider), and the phones he buys are programmed by Siemens in an
appropriate way. This has also an effect on the repair process. Please refer to the
chapter „Customer Specific Initialisations“ in this manual.
4 Mechanical Concept
Note: All part numbers refer to mechanical drawing in section 4.1!
The mechanical c ncept f the S25 differs in vari us p ints fr m the ne f the ther Siemens
m bile teleph nes.
The first thing y u will experience is h w the h using is l cked. The h using c ncept is
similar t the ne f C25, meaning that in S25 n screws are used t keep the h using cl sed.
Als inside the teleph ne n screws are used anym re. T pen the h using, which is kept
cl sed by catches nly, the same pening t l as f r C25 can be used. F r details n
disassembly please refer t the relevant chapter in this manual.
In pp site t C25, in S25 the battery is part f the h using f the ph ne, s there n separate
battery c ver is necessary.
Inside the h using the S25 c nsists f tw separate b ards, the MMI m dule (1010) and the
RF/C ntr l m dule (1000). The b ards are interc nnected n t by a plug r an interc nnect r
as kn wn e.g. in S6 ph nes, but by a flexible cable (1030). This cable n t s ldered t the
b ards, but plugged int tw c nnect rs. Theref re it can be exchanged easily in case f being
damaged.

The ringer (1120) f the ph ne is mechanically fixed n the RF/C ntr l b ard by a special
clip (1190) and electrically c nnected t the b ard by means f a cable and a plug. In the
same way the vibra alert unit (1160) is c nnected, s b th c mp nents can be exchanged
with ut d ing s ldering w rk. In S25 the vibra alert unit is n t a part f the battery but f the
ph ne itself.
Dust pr tecti n frame (1200), c ver f r IR-interface (1280) and l udspeaker (1140) including
spacer (1250) are m unted t th upper h using (1060). The l wer h using (1070) carries
antenna (1150), battery c ntacts (1170), micr ph ne (1130), vibra alert unit (1160) and the
butt ns f r v ice mem (1350) and side keys (1340).
The antenna (1150) is f a plug-in type, as it is used in Siemens m biles since C10/C11.
Attention:
The antenna f C10, C11, C25 and S25 are f different types. Be carefull n t t mix them up.
S25 carries the same type f external c nnect r as it was intr duced with C25. This new
„Lumberg“-c nnect r d es n t feature c nnecting an external antenna, and theref re there is a
separate c nnect r f r external antenna l cated at the back side f the upper end f the
m bile, cl se t the internal antenna (1150). This c nnect r c ntains the mechanical antenna
switch inside. The switch is perated by inserting the appr priate plug e.g. f a car kit
c mf rt.
T perf rm measurements n the S25 and f r s ftware updates the same adapter cable
between b tadapter and m bile can be used as it was f r C25. F r further inf rmati n n the
testequipment please refer t the appr priate d cumentati n r c ntact the technical supp rt
department.

4.5 Handset Datecodes
Siemens is using the industrial standard DIN EN 60062 t indicate the pr ducti n / service
dates. The c de is printed n the IMEI sticker l cated in the battery c mpartment.
YY = Datec de
•The first character f the datec de indicates the year f pr ducti n:
F = 1995
H = 1996
J = 1997
K = 1998
L = 1999
•The sec nd character indicates the m nth f pr ducti n:
1-9 = january t september
O = ct ber
N = n vember
D = december
Example: “L5” means that the set was pr duced in may f 1999.

5.2 Hardware Description
The handset c nsists f the f ll wing maj r integrated circuits:
1) HiGOLD (PMB 2800)
This IC is a c mbinati n f micr pr cess r and signalpr cess r.
The micr pr cess r part f this c mp nent is resp nsible f r c ntr lling the keyb ard, SIM-
Card, Flash and RAM. Furtherm re it c ntr ls the p wer up/p wer d wn f the RF m dule
and sets the amplificati n f the PA.
The signal pr cess r part f PMB 2800 is resp nsible f r pr cessing the Rx I/Q signals
(filtering, equalizing, speech and channel dec ding).
Furtherm re it d es the speech and channel enc ding and the GSMK m dulati n f the Tx
I/Q signals.
2) GOLD-SX (PMB 2709)
The c pr cess r PMB 2709 is used t realize advanced features regarding c ding f the
speech signal. These are:
•Halfrate-Enc ding
•Halfrate-Dec ding
•Enhanced Fullrate Enc ding
•Enhanced Fullrate Dec ding
•V ice Activity Detecti n
•C mf rt N ise
3) GAIM (PMB 2905)
The GAIM (GAIM = GSM Anal g Interfacing Mdule) pr vides the interface between the
anal gue signals (I/Q, v iceband, PA-c ntr l, charging c ntr l signals) and its digital
representati n.
4) Receiver Circuit (PMB 2411)
This circuit pr vides the f ll wing main functi nalities:
•L w N ise Amplifier (LNA) with a fixed amplificati n f +20dB t amplify the input
RF signal.
•Mixer t mix d wn the RF signal t the Intermediate Frequency (IF)
•Pr grammable IF amplifier with a dynamic range f 60dB ( -10dB ... +50dB in steps f
2dB).

•Mixer t mix d wn the IF signal t the baseband, generating and inphase (I) and a
quadrature (Q) signal.
•Offset c mpensati n f r the I/Q signals.
5) Transmitter Circuit PMB 2255
This circuit pr vides the IF synthesizer, the I/Q m dulat r, prescalers t regulate the RF
synthesizer and a buffer stage t feed the PA.
The antenna switch is mechanical, l cated in the c nnect r f r the external antenna.
