Adjusting the saddle height is easy - just use an Allen key (hex key) on either side of the string to raise/lower.
The intonation is a little unusual, in that there is no screw to move the saddle back or forth. But - with the string loosened, it will slide back or forth easily, and stay in that position once the string is back under tension.
Bit of a pain, as you'll have to guess where it'll end up while the string is tuned, loosen it, slide the saddle to where you guess, tune up again, check against the 12th fret, and keep doing that until you're happy that it's in the correct place. Once done, though, it'll stay there until the string gets changed, and shouldn't need moving even when that happens, if the same gauge is used. Worth double checking though...
If it was my bass, I'd be swapping that bridge for a more comprehensive and easier to use bridge, which shouldn't break the bank, and be far less frustrating to set up.
