must be baked before use gen.

[Medis1]

Notes
1. Packages that are not sensitive to moisture do not require DRYPACK.
2. MSL 6 packages must be baked before use, after which they have a 6-hour floor life.

MSL здесь moisture sensitivity levels

но я не пойму что здесь может означать " must be baked before use"
