ADJUSTMENTS
5V
When replacing IC1, LM3578, on PCB2, Switch-Mode Power Supply, the supply
voltage may have to be adjusted to 5V ±0.25V by means of R2 and R10:
- If 5V is above level, install R2 (R1//R2).
- If 5V is below level, install R10 (R3//R10).

SPEAKER
Adjustment of bass/treble sound level.
To be carried out only when replacing a speaker unit or PCB36, Microcomputer.
TEST MODE 01
This test mode permits manual adjustment of speaker bass and treble levels and
can only be executed from stand-by with a Beo4.
- Press MENU 0 1 GO.
The display reads SPK.CAL. to indicate that the product is ready for speaker
calibration.
- Press GO.
The display shows the present adjustment:
‘X X X X’ = left bass (LB).
‘X X X X’ = left treble (LT).
‘X X X X’ = right treble (RT).
‘X X X X’ = right bass (RB).
The value that can be changed is flashing. Press >> or << to change unit of
adjustment, and change the value by pressing the digit keys. When all four
speakers have the desired encoding, press STORE, and abandon test mode by
pressing STOP.
2.
Adjustments
Replacement of PCB36, Microcomputer
The bass and treble levels of the speakers are stored electronically in the
Microcomputer (PCB36). When replacing PCB36, the original bass and treble level
values must be restored:
- Install the new Microcomputer (see section 4, Disassembly, if necessary).
- In TEST MODE 01, enter the values printed on the label in the socket well:
LT (left treble) : X LB (left bass) : X
RT (right treble) : X RB (right bass) : X
- Press STORE STORE when all four speakers have been encoded as desired.
Replacement of a speaker unit
A rated value in dB is printed on the back of the new speaker unit. This value is
used for adjusting the sound level, which is done in TEST MODE 01:
- Note the value on the back of the new speaker unit
- Replace the old speaker unit.
- Execute the point TEST MODE 01.
- The rated value printed on the back of the speaker may be either positive or
negative:
Positive:
If the rated value printed on the back of the speaker is positive, the unit in
question must be damped by X number of steps. Press >> to select speaker, if
necessary (the active speaker is flashing), and enter a new digit (see table).
Negative:
If the rated value printed on the back of the speaker is negative, the other three
units must be damped by X number of steps. Press >> to select the three speakers
in question, and enter new digits (see table).

REPAIR TIPS
BeoLab 3500 can be brought into TEST MODE from stand-by with a Beo4, giving
access to the following functions:
TEST MODE 00
Display of: Software version number and time of operation in Audio mode, Video
mode and stand-by.
- Press MENU 0 0 GO.
The display reads: SW X.Y, which is the software version number.
- Press m
The display reads: A: XXXXX, which is the Audio mode operating time in hours x 10.
- Press m
The display reads: B: XXXXX, which is the Video mode operating time in hours x 10.
- Press m
The display reads: C: XXXXX, which is the stand-by operating time in hours x 10.
Press m or p to scroll in the scroll menu, and abandon test mode by pressing STOP.
TEST MODE 01
Electronic adjustment of the bass and treble levels of the speakers. See section 2,
Adjustments.
SERVICE SET-UP
BeoLab 3500 is connected to a Beomaster as an ordinary Master link installation.
As regards option programming, see User’s Guide.
TEST MODE 02
Display of Master Link error types. Gives an identification of the error types that
may occur in the Beolink installation.
-
Press MENU 0 2 GO
The display reads:
ML OK

ERROR 4
=
The Master Link connection is OK.
Master Link is not connected.
Address configuration impossible.
Master Link data pulled low.
Master Link data pulled high.
Data collision on Master Link.
- Press STOP to abandon display of Master Link error types and to delete registered
errors.
The Master Link error system is a part of the software in the product. It registers
communication errors between the microcomputer, the data transceiver circuits
(PCB35) and the products connected to BeoLink. The error types will be described
below, and tips will be given regarding how the cause of the error can be found:
3.
Repair tips
ERROR 1:
Error during address configuration. No address has been allocated because too
many units are connected to the BeoLink.
- Remove all products from BeoLink, and connect them again one at a time until the
error code occurs. Disconnect that product from BeoLink.
ERROR 2:
It is not possible to transmit on BeoLink, because it has been pulled low. The error
may occur if there is no Master Link driver circuit, or as a result of a physical shortcircuit on BeoLink or in the data transceiver circuits.
- Disconnect one product from BeoLink at a time, and see if it starts up.
- Reset the faulty product, and check the connection (cable/plug) and signal path
(the data transceiver circuits).
ERROR 3:
It is not possible to transmit on BeoLink, because it has been pulled high. This
error is caused either by the pull-up resistance in the system having become too
small or by an error in the data transceiver circuit.
- Disconnect one product from BeoLink at a time, and see if it starts up.
- Reset the faulty product, check whether the Master Link cable is too long, and
check the signal path (the data transceiver circuit).
ERROR 4:
The data traffic on BeoLink has been excessive, or a product has jammed and will
not receive telegrams.
- Press the operating sequence again.
- Disconnect one product from BeoLink at a time to determine which product has
jammed. Reset the faulty product, and check the Master Link connection (cable/
plug) and signal path (amplifiers in the data transceiver circuit).
TEST MODE 0 3
Direct selection of Master Link input. Permits the Master Link signal path to be
tested without having a BeoLink master connected.
- Press MENU 0 3 GO
The display reads:
ML SEL.
=
Opens the Master Link signal path.
- Press STOP to close the Master Link signal path.
Disassembly
4.
DISASSEMBLY
Front fabric frame
- Push the front fabric frame to the side and lift it off.
When both front fabric frames have been removed, PCB35, Display, Keyboard & IR
receiver, PCB36, Microcomputer, and PCB32, Cross field, are accessible:
- Remove the display glass (two screws) and the two plastic covers (four screws).
PCB35 can now be tilted out into service position, thereby also providing access to
PCB36 and PCB32.

Disassembly
Service position
Important!
The display glass and cabinet must be protected against scratches by placing them
on a soft base.
- Remove the sixteen screws, A, behind the front fabric frames.
- Place the front face down.
- Remove the socket well by first removing the two Allen screws.
- Lift the cabinet up and off carefully. Place the cabinet parallel to the electronics
block, and remove the two woofer plugs (22P4) if necessary.
- When assembling the product, lower the electronics block carefully down into the
cabinet. Place the woofer leads at the centre of the cabinet so that they will not
rattle against the cabinet sides.

Insulation test
5.
INSULATION TEST
Each set must be insulation tested after dismantling. The test is to be performed
when the set has been re-assembled and is ready for delivery to the customer.
Make the insulation test as follows: Short-circuit the two plug pins of the mains
plug and connect one of the terminals of the insulation tester. Connect the other
terminal of the insulation tester to the chassis of the 8-pin DIN socket.
N.B.!
To avoid ruining the set, it is esential that both insulator test terminals are in really
good mechanical contact.
Now turn slowly the voltage control of the insulation tester until a voltage of 1.3kV
is obtained. Hold it there for 1 second, then turn slowly the voltage down again.
At no point during the testing procedure any flash-overs are permissible.
