Hi Rado,
Hi and
to IIS. A great place to learn and get your questions answered.
I'v had my G11 with gemini II for about 3 yrs and I am very happy with it.
As has been said before, its doesn't come with a manual but Rene has put together a great online manual here.

The G11 was my first foray into this hobby and found it fairly easy to get to understand how to work it.
