Beside charging the battery?
Read the manual should be the second but... Honestly, who does?
What you should do (Two + 1) is to check the ISO settings (once the battery is charged of course).
Why the ISO setting? Simple, ISO. It is the most important setting of your camera and few are even aware of it.
ISO directly influence the dynamic range (DR) of every single capture. The greater the ISO the greater the loss in DR. High ISO also introduces noise and in some instance can create a chromatic disturbance. I have not seen the last one but it has been reported several times. Another issue is when you use a priority anything with ISO on the loose. The results are basically unpredictable.
Depending on your camera sophistication you can create an ISO 'limited' auto mode by using a minimal or maximal ISO the camera can use. You are essentially creating an ISO range for the camera to use. Too many cameras only offer a set ISO or a 'loose ISO' as auto.
Note that newer cameras, mostly higher priced, use a new technology where the ISO while still important becomes less so.
The next setting? I do not intend to create yet another 'fight' as this post is enough...
