Ideally you should look in the manual for the scope to figure out
exactly where the cells are.

As a poor hobbyist i bought it on a second hand market.
No manual.

Without a manual, you'll have to peel up a few Pc boards for better
seeing.

No battery found.
I have just looked inside again.
With a mirror i could see (almost) everything.
Only a extremely small battery would not be noticed.
I see no batteries, of the penlight type, nor any other type of battery.

Has anyone a idea how the current settings are stored in this Philips/Fluke
PM3070/021 oscilloscope ?

I just noticed you can get the channels back by pushing the A/B button.
Not only by pushing the AUTO SET button.
The channels are then on the most sensitive scale.
Maybe this info helps to identify the problem.

Take care.

Wise words :-)
I was nervous :-)
Everything went well, the scope still works :-)
