Explanation of diagram
Explanation of diagram
Component print and coordinate system
Control circuit
Wiring connections
Type numbers of transistors and ICs are indicated on the diagrams. If the position
is followed by an asterisk the spare part number must always be used because the
component in question has been specially selected, e.g. TR102*.
The largest PCBs have component prints and a coordinate system on both the print
and the component side.
On the diagrams every component has a coordinate number. This indicates in which
coordinate on the PCB the component is situated. The coordinate numbers are
written in smaller print types than the position numbers.
In certain control circuits the active mode is indicated by a function term or by an
abbreviation. This may be e.g. ST.BY. = low in the stand-by mode or ST.BY. = high
in the stand-by mode.
The wiring connections on the diagrams are assembled in ‘bundles’. The individual
wires are provided with one of the following codes:
INTERNAL CONNECTION ON ONE DIAGRAM PAGE
12
Internal connections on a diagram page are indicated by a number.
The bend of the wire indicates in wich direction the other end of the wire is found.
CONNECTION TO ANOTHER DIAGRAM PAGE
DIAGRAM A
C3
C32A32
A connection to another diagram page is indicated by a number as well as by a
letter of the diagram to which the connection leads.
Supply Voltages
All supply voltages in the diagrams are indicated by an arrow and a voltage indication.
Ground symbols
Three different ground symbols are used in the set.
= RF - OSC - SH - IF1 - IF2 - A
= Chassis
20
DIAGRAM C
1220
A3
Symbol of safety components
= D
When replacing components with this symbol, components with identical part
numbers must be used. The new component must be mounted in the same way
as the one replaced.
Page 10
Measuring conditions
Caution
Explanation of diagram
All DC voltages have been measured in relation to ground with a voltmeter with
an input impedance of 10 Mohms.
The DC voltages are stated in volts (V), e.g. 0.7V.
All oscillograms and AC voltages have been measured in relation to ground with
an oscilloscope or a voltmeter with an input resistance of 1Mohm.
AC voltages are stated in millivolts (mV), e.g. 660mV.
The use of any controls, adjustments or procedures other than those specifi ed
herein may result in hazardous radiation exposure.

Test of Master Link DATA receiver/transmitter
Test of the circuits 12TR30, 12TR31, 12TR52, 12TR53, 12TR55, 12TR56 and 12IC6.
- Lift P107.
- Mount on P4.
- Connect a square-wave generator 10kHz 0-5 V to P107-4 (transmit).
- Measure P107-2 (receive) with an oscilloscope; it should produce the same signal
as the one transmitted by P107-4, only here it is delayed by 10-15 µS.
To prevent that products connected via the Master Link socket destroy the data
communication in the case of an error in the data interface, the data interface
circuit has been designed so that components can be defective without causing a
malfunction.
For example, the diodes mounted in connection with Data- and Data+ are protection
diodes which will protect against static electricity.
Consequently, when making a repair, it may be necessary to replace/check several
components.
If 12TR55 is defective, both 12TR55 and 12TR56 should be replaced and the
diodes 12D4, 12D5, 12D19, 12D20, 12D21 and 12D22 should be checked.
If 12TR56 is defective, both 12TR55 and 12TR56 should be replaced and the
diodes 12D4, 12D5, 12D19, 12D20, 12D21 and 12D22 should be checked.
If one of the diodes 12D4, 12D5, 12D19, 12D20, 12D21 and 12D22 is defective,
all of the diodes should be replaced, and 12TR55 and 12TR56 should be checked.
CD laser current
Across 80R3121 (4.7 ohm) the measurement in mV will show the current in the
laser beam. Typical measure; ap. 300 mV. If over 450 mV the laser-head is defect.
Eyepattern
The eyepattern can be measured between 80P1001 pin 5 and 80C2116 (1.3Vpp).
Exchange of microprocessor module PCB3
When exchanging PCB3 remember to insert the EEPROM from the defective
module, because it contains valuable data (serial no., type no., PIN-code etc.).
The data is not transferred to the new module untill you have been in contact with
the theft protection or after 12 hours connected with mains. This means that you
can try out a new PCB3 without transferring the products serial no. Etc..
Note !
When the serial no. has been transferred to the micro-processor it can only be
used for this specifi c product; it must go back to Bang & Olufsen’s module repair
department as an exchange module to be erased again.
If the product functions are OK the theft protection is also OK; there is no need for
testing the functionality of the theft protection.
When the product is connected to mains, wait 20-30 sec. before operating.
All addresses in ML has to be updated after disconnecting mains voltage.
Page 63
Theft protection
Service code
Service- and pin code, English 5.15
The theft protection is a 4 digit PIN-code, of the user’s own choice, which must be
entered if the product has been disconnected from the mains for 15-30 min.
The theft protection is always deactivated from the factory, it is up to the user to
activate it.
If the theft protection is activated, and the product has been without mains for
15-30 minutes, the user will be asked to enter the 4 digit PIN-code.
Before the product is handed in to service it is a good idea to ask the customer to
deactivate the theft protection.
If the PIN-code is activated and the product is in a service situation, there is a
possibility of 12 hours service by entering a 5 digit Service code which is 11111.
This gives 12 hours of full functionality to service the product and make module
changes without naming/registering the exchanged modules to the Customer’s
product. The 12 hours are only running when the product is connected to mains!
If the customer’s PIN-code or Master-code is entered the exchanged modules will be
named/registered to the product. Registration of the modules cannot be changed.
The service code must be entered when a source is selected and the product asks
for the PIN-code “PIN _ _ _ _” press down the
and the display now writes “PIN _ _ _ _ _”, and the Service code 11111 can be
entered.
l (rewind) button for three seconds
Master code
If the PIN-code has been forgotten (5 tries every 3 hour with mains connected),
the only way to unlock the product again is by entering the 5 digit Master code.
The Master code can be ordered at Bang & Olufsen.
When a source is selected and the product asks for the PIN-code “PIN _ _ _ _”
press down
of 4: “PIN _ _ _ _ _” ; enter the 5 digit Master code.
How to order Master code
The Master code is ordered by sending a request either via the Retail System or on
the Master code formula, if non of these options are available please contact Bang &
Olufsen.
Exchange of microprocessor module PCB3
When exchanging PCB3 remember to insert the EEPROM from the defective
module, because it contains valuable data (serial no., type no., PIN-code etc.).
The data is not transferred to the new module untill you have been in contact with
the theft protection or after 12 hours connected with mains. This means that you

Exchange of software EEPROM on PCB3
When exchanging the EEPROM on PCB3, the data from the micro-processor will be
written into the EEPROM when selecting any source e.g. RADIO.
It is possible to borrow an EEPROM from another BeoSound 3000 to test if there is
suspicion of a fault in the original EEPROM. The EEPROM will always adopt the
data from the main micro-processor.
Exchange of both micro-processor module PCB3 and software EEPROM on PCB3
If both the micro-processor and the EEPROM need to be exchanged it is necessary
to have them pre-programmed from Bang & Olufsen with the correct serial number,
otherwise they will not work.
Please contact Bang & Olufsen.

When the product is reconnected to mains, wait 20-30 sec. before operating.
All adresses in ML has to be updated after disconnecting mains voltage.
It is your own choice whether or not to activate the PIN code system. However, if
you choose to activate the system, your BeoSound 3000 is protected against theft
with a four-digit PIN code.
The use of a PIN code means that if your BeoSound 3000 is disconnected from the
mains for more than 15-30 minutes, the system can only be activated again by
keying in your own personal PIN code.
If the PIN code is not entered, the BeoSound 3000 automatically switches to

To avoid damaging the set it is essential
that both terminals of the insulation
tester have good contact.
Slowly turn the voltage control of the
insulation tester until a voltage of 2.5kV
is obtained. Maintain that voltage for
one second, then slowly turn it down
again.
Isolationsprüfung
Nach der Zerlegung muß bei jedem
Gerät eine Isolationsprüfung
vorgenommen werden.
Prüfung vornehmen, wenn das Gerät
zusammengebaut und zur Auslieferung
an den Kunden bereit ist.
Während der Prüfung dürfen keine
Überschläge auftreten!
Isolationsprüfung folgendermaßen
vornehmen:
Beide Stifte des Netzsteckers
kurzschließen und mit einer der Klemmen
des Isolationsprüfers verbinden. Andere
Klemme des Isolationsprüfers am
Masseanschluß der Kopfhörerbuchse
anschließen.
ACHTUNG!
Um Beschädigungen des Geräts zu
vermeiden, müssen beide Klemmen des
Isolationsprüfers unbedingt einen
einwandfreien Kontakt haben.
Spannungseinstellung des
Isolationsprüfers langsam auf eine
Spannung von 2,5 kV erhöhen. Diese
Spannung eine Sekunde beibehalten,
anschließend langsam verringern.
Test d’isolement
Il convient de soumettre l’appareil à un
test d’isolement après l’avoir démonté.
Ce test est effectué après avoir
réassemblé l’appareil et avant de le
remettre au client.
Aucune étincelle ne doit se produire
lors du test !
Procéder au test d’isolement comme suit :
Court-circuiter les deux broches de la
fi che secteur et les raccorder à l’une
des bornes du testeur d’isolement.
Raccorder la seconde borne du testeur
d’isolement à la broche de masse de la
fi che femelle du casque.
ATTENTION !
Pour éviter d’endommager l’appareil, il
est important que les deux bornes du
testeur d’isolement soient en parfait
contact.
Tourner lentement la commande de
tension sur le testeur d’isolement
jusqu’à arriver à 2,5kV. Maintenir cette
tension pendant une seconde, puis la
diminuer lentement.
