CHANGES DURING PRODUCTION
FRONT CONTROL BOARD
* From production wk204 onwards the following changes
are made to improve brightness & reliability of the Blue
LED.
3601 change to 33R 5% 0,062W 4822 051 30339
3602 change to 33R 5% 0,062W 4822 051 30339
ETF TAPE MODULE
* From production wk209 onwards a new ETF8 SD Tape
Module was introduced replacing the existing ETF6-LE
Tape Module. Due to this change the undermentioned
changes needs to be implemented together:
On the Front Board
7102 is change to 9965 000 11077 TMP88PU74YF.
This is the OTP version of new IC which can be recog-
nized by the "MC50S52881" printed on the body of the IC.
On the Center Unit (Refer to Set Exploded view)
Pos 198 is change to 3139 114 73930 Door Cassette
A new Chapter of the ETF8 Tape Module is enclosed. It
can be recognized by the the printing mark
3139_113_34552_01 on the pc board.
3DTC MODULE
* From production wk205 onwards a new pc board pt. 5 is

Already published Service Informations: A01-164 3139 785 30023
3139 785 300612002 - 04 - 26
for other set application. Because the existing module
has dedicated circuit diagram for this set, no changes is
required on the circuit. Enclosed is the new pt.5 layout.
COMBI BOARD
* From production wk202 onwards a new pc board pt. 2 is
introduced to improve GSM immunity & cater for other set
application. Due to this new board the following changes
are made:
2542 change to 1nF 10% 50V 4822 122 33197
2543 change to 1nF 10% 50V 4822 122 33197
Add 2650 220pF 50V 4822 126 13883
Add 3673 470R 5% 0,1W 4822 051 30471
Add 3674 470R 5% 0,1W 4822 051 30471
Add 4549 0R Jumper 0805 4822 051 20008
Add 5511 Ind. fxd 100MHz 600R 2422 549 44607
Add 5512 Ind. fxd 100MHz 600R 2422 549 44607
The new pt.2 layout & affected circuitry are enclosed for
reference.
REGULATOR BOARD
* From production wk212 onwards a new pc board pt. 4 to
improve MW/LW sensitivity & noise for other application
sharing the pc board. Added on the board are compo-
nents 2417 and 2420.
The silkscreen printing on the pc board is later changed
to pt. 5 to correct item 3433 & 3434 interchange error.
The new pt.5 layout & circuitry is enclosed for reference.
