Suggest you review the User Manual, which can be found here:

The 42S is a sophisticated and powerful device, and you'll need to spend a lot of time exploring it before you'll understand many of it's capabilities, which is much easier if you follow the manual. If things are still unclear after reading that on whatever topic you are exploring, feel free to post questions, but please respect other peoples time and attention by putting in some effort yourself before asking folks here to answer your questions.
