David, Since this is a duplicate problem, I'll give a duplicate answer. :-)
It is easiest to link you to your
camera manual.
Click on:
Kodak CX4230 Manual
Go to page 20 in the manual for instructions.
While you have it open, save a copy to your
computer for future reference.
Here it is if you don't want to do that:
In Capture mode, press the Menu button.
Highlight Self Timer , then press the Select button.
Highlight On, then press the Select button.
Press the Menu button to turn off the menu screen.
Place the camera on a flat surface or use a tripod.
Press the shutter button completely down to take the picture.
The red Self Timer light turns on for 8 seconds, then blinks for 2 seconds. The picture is taken.
Take some good Christmas Pics! Merry Christmas!
