03.01 TYPENUMBER(S): GENERAL
INFORMATION : Service Information A99-572 (3140 785 22022) is published to
introduce the survey of service spareparts for those typenumbers in
category 1, for which no Service Manual has been published.
In this additional issue, the following typenumbers are new:
Portable radio : AE2180, AE6776, AE6780
Clock radio : AJ3141, AJ3142, AJ3143, AJ3144, AJ3145
Radio Cass. Recorder: AQ4150/..S, AQ5150/..S
Headphone Stereo : AQ6411, AQ6412, AQ6413, AQ6414, AQ6682
REMARKS :
03.02 TYPENUMBER(S): AZ1120
INFORMATION : In course of production, the following parts have been changed to
improve DBB perfor mance:
• Capacitor 2503 and 2504 changed to 68nF (5322 121 42465)
REMARKS : Modification has been implemented in production from week 9921
onwards.
03.03 TYPENUMBER(S) : AZ2000, AZ2010
SYMPTOM :
Sets are not working on some batteries (e.g. Energizer batteries)
because the battery plate fails to contact with the batteries.
CURE : The cabinet wall holding the battery plate is too thick.
The simplest service solution is to add a washer (of 0.5 - 0.7mm
thickness) behind the battery plate to compensate the tolerance.
On long term, the battery plate will be modified to increase the height
of the contact point.
REMARKS : Modification has been implemented in production from week 9926
onwards.

03.04 TYPENUMBER(S): AZ2402, AZ2407
SYMPTOM :
No FM reception at the higher end frequencies of the FM-band, when
Volume is set to maximum and MODE button is pressed.
CURE : Problem can be solved by changing following parts:
• Capacitor 2322 and 2326 changed to 22µF (4822 124 81151)

of the Front board will be modified and following par ts will be changed
or added:
• Resistor 3456 changed to 15kΩ (4822 116 52244)
• Resistor 3457 changed to 5.6kΩ (4822 116 52289)
• Resistor 3516, 47Ω (4822 116 52195) added
• Diode 7483 and 7484, 1N4148 (4822 130 30621) added

03.07 TYPENUMBER(S): AZ7381, AZ7382, AZ7383, AZ7481, AZ7482, AZ7483
INFORMATION : In course of production, the PCB Assembly was changed to PB2 (for
details please refer to Service Manual 4822 725 26021).
In the PB2 assembly a smaller headphone jack was used and thus
the hole for h/p jack on the cabinet was also made smaller.
The cabinet (4822 449 80201) of the sets produced in earlier stage is
no longer available and the new cabinet (4822 449 80266) with
smaller jack hole will be delivered as substitute.
As a service solution, for repairing sets with bigger headphone jack,
we suggest to enlarge the hole by use of files (see drawing below).
REMARKS :
03.08 TYPENUMBER(S): MC165, MC175
