muy buen manual por lo completo de este algunos esquemas estan muy divididos lo que hace algo dificil el seguimiento.
;
very good manual, with detail and clarity in esquematic diagrams and waveforms .
 ;
Very quality copy of original service manual, which contains the circuit diagrams, PCB and lists of components, well as recommendation for calibration procedures of device, also everything else, that need for repair, tuning and use this oscilloscope.
All presented copies have high-resolution, so you can view all in detail.
This manual will very useful for simple owners and for repairers.
I recommend these manual, because myself is owner of Philips PM3216 and I need sometimes servicing these oscilloscope (principally calibrating).
Also, these document is an example of excellent design of technical documentation.
;
Excellent printing quality.
A complete and very usefull service manual with all details.
GREAT SERVICE AT VERY LOW PRICE!

7. GENERAL INFORMATION
7.1 SINGLE OPERATION METHOD
Single operation method and inputlevel.
The procedure and the input level of a single operation are shown below. 1. R85 are shorted by 1k�. 2. A point of the figure below in four places is connected. GND is not common because it is independent with chassis GND (GND of the amplifier), B1GND, B2GND, and B3GND. The potential of B1GND, B2GND, and B3GND is done by connecting A point in four places as well as chassis GND. 2. The power supply of the product is turned on. 3. the terminal CONT (2 pin of CN3332) are controlled respectively by the following voltages. CONT 5V ON ON
12V RY MUTE ON OFF
0V OFF ON
4. The signal of 10mV is input from input terminal (JA3333), and the output is confirmed with speaker terminal (CN3331). Note : If the music signal is input directly to input terminal (JA3333) with CD PLAYER etc. , the output becomes a large volume because there are 40dB GAIN of the amplifier.

R85 � 1k�
Caution when disassemble. Even if the power supply code is pulled out from the outlet, neither C11 nor C12 of AF ASSY are discharged. Please discharge C11 and C12 of AF ASSY by the resistor of 100 � or more before removing AF ASSY or POWER SUPPLY ASSY. There is a possibility to destroy the transistor, and Please discharge by the resistor of 100 � or more.
