Google "DT 9205A schematic" buddy. You'll get all the info you need there.

Try to download a schematic of the DMM.
On the schematic, trace the switch functions vs positions and which components they go to.
Follow the same paths on the PCB switch-tracks.
Now you can see which circular tracks should be bridged when.
From there you can align the contacts correctly.
Some meters also have a 'key', or matching hole/bump for correct alignment.

Actually you can simply try and discover the correct position to match the writing on the case.
The switch is a 360 degrees rotatory one,turn it and try to find the diode/continuity position.

Do this:
Insert test leads and short them permanently together.
Rotate the switch till you hear the continuity beep sound.
Congratulations your meter is oriented.:)
