Panasonic C-D3100ZM-S - Flash-off infinity lock mode; Slow shutter speed to bulb

Flash-off / Infinity lock mode
When you wish to take a picture of a distant view or through a glass
window, select the infinity symbol on the LCD panet by pressing the
Flash mode / SELECT button before pressing the shutter release
button. The flash will not operate in this mode to avoid reflection in
windows and because it's unnecessary for distant subjects.
* If the green LED blinks slowty when the shutter release button is
pressed halfway, it means that there is a risk of camera shake. If
so, use a tripod or brace yourself against a wall,
* If the "B" mark appears on the LCD, it means that the shutter is set
to "Bulb" (see the section "Slow shutter speed to Bulb”.)
Stow shutter speed to bulb
In the three modes shown above, the shutter speed is adjusted
automatically from slow to “Bulb” depending on the light level. For
example, when you take a picture in the dark such as a night view,
the camera shutter changes to “Bulb” automatically.
In this case, "B` appears on the LCD panel when pressing the shutter
release button halfway. This means that the shutter will be open as
long as pressure is maintained on the shutter release button (max:
99 seconds)
. There will be a risk of camera shake so it is best to use a tripod (not
included).
