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.

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.

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

introduced due to the addition of a HF detection circuitry

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.
