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.

Clean the object lens by an applicator with neutral detergent when the signal level is low than specified value with the following checks. 5. Check the focus bias check when optical block is replaced. FOCUS BIAS CHECK

Confirm that the oscilloscope waveform is as shown in the figure below. (eye pattern) A good eye pattern means that the diamond shape (�) in the center of the waveform can be clearly distinguished. � RF signal reference waveform (eye pattern)
VOLT/DIV: 0.2 V (with the 10: 1 probe in use.) TIME/DIV: 500 ns
4. Press the [BASS/TREBLE] button, the model name and distination are displayed. example of display:

5. To exit from this mode, perform the �COLD RESET�. TUNER STEP CHANGE-OVER * Either the 9 kHz step or 10 kHz step can be selected for the AM channel step. Procedure: 1. Set the FUNCTION to AM, and press the I/1 button to turn the power off. 2. While depressing the [TUNING + M > ] button, press the I/1 button. 3. The message �9K STEP� or �10K STEP� is displayed on the liquid crystal display, and thus the channel step is changed over.
