SF-24D Flash Questions (and does anyone have the Manual please)

Hello 

I'm posting this here as I use this flash with my M6 TTL , but I wasn't sure where in the forum to place a couple of questions. 

1) Today I was using my SF24-D in Auto mode (ISO set at 250, aperture set at F8 if it matters).  The display (with no exposure compensation) read 2.4m .  However, when I dialled in -1 flash exposure compensation, the readout increased to 3.4m.    Assuming that this readout tells us the reach of the flash,   I would expect the figure to decrease with negative flash compensation, and increase with positive flash compensation.   But in fact the readout suggests the opposite ... Can someone please explain to me why this is the case ?

2) Does anyone happen to have an electronic copy of the Manuel for SF-24D.  I can only find other languages online, I am yet to find the English one 

3) Finally, can anyone recommend a good small wireless trigger that would work with this and other flashes to use it wirelessly off camera. I presume Auto mode will still work perfectly as the settings are dialled in on the flash itself and it has a sensor. 

Cheers for any help !

Thanks @Graham (G4FUJ), Thanks @Al Brown ....  from the manual I have answered my question #1 also

My Metz 34 CS-2 auto flash works like that too.  The distance indicates the maximum distance that the flash has enough power to light the scene, given the f-stop in use.  So, if I added -1 stops of exposure compensation, the flash must generate on-stop less light level, hence the maximum range increases.

Thanks . I think I understand , so in Auto mode the weaker intensity output of the -1 adjustment means more reserves to reach subject if its full power is needed (as determined by the sensor on the flash > subject distance) ?

Leaves me to wonder how manual mode works, because that one works as I originally expected (i.e. a "-1" adjustment means less max distance).   I think it may be because in Manual mode the flash always fires at its max intensity.  So maybe it fires quicker at -1, hence covering less distance  🤔
