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.

A complete and very usefull service manual with all details.
GREAT SERVICE AT VERY LOW PRICE!

The service manual is a good quality scan of the Panasonic NV-850, which is electrically identical to the Philips VR 6920, but mecanically just nearly.

Since detection circuits cannot be unified into one even with the above conversion, turn the IF to 6.0 MHz for all methods by utilizing a frequency difference of 0.5 MHz between each IF. When IF = 5.5 or 6.5 MHz: Mix an oscillator of 0.5 MHz to turn it to 6.0 MHz. 6.0 MHz: Nothing is to be mixed. In other words, by turning a mixer of 0.5 MHz on for methods B, G, H, D and K or off for I, sound detection is enabled with only one detection circuit of 6.0 MHz. The multi-SIF refers to such a method as explained above which enables SIFs of each method (B, G, H, D, K and I) to be detected.
