Seems you mean *Friend* level.
From the help files, which seems to be a bit unclear:

<quote>Menu: Game – Levels – Friend mode

In this mode the program automatically adjusts its level of play to match that
of the opponent. When you start, it asks you for your “Handicap”. This is
similar to golf and is measured in 100ths of a pawn. If you give a high value
(e.g., 200 = two pawns) the program will reduce its strength considerably.
Afterwards the program will adjust your handicap to reflect your real playing
strength. The smaller your handicap, the stronger you are. Top players will
indeed achieve a negative handicap. If after about six games the program sets
your handicap to below –400 (= minus four pawns), you are advised to practice
elementary chess tactics and to concentrate on avoiding material loss. You
should consider using the coach functions “Threatened squares” and “Show
threat”.

The “Friend mode” can be used by beginners and strong players alike. The chess
clock only records the time and has no further relevance, so you can think for
as long as you like.

The "below -400" is wrong. That must be "above 400" or so  Your handicap is -as
in golf- positive. So when playing a lot of losing games your handicap will end
at some +700 or 900 or so.

Friend mode is a modern form of "odds".

Try playing some rated games. Roughly calculating your own level, add some
150-200 points and start playing rated games. After appr. 20 games you will have
a rating by Fritz and can use it to be roughly on par with Fritz at that
handicap and fun level.

Good luck.
