Same problem new camera, 4 different sets of batteries. green light beeps 3 times and goes off

The 3 beeping sound as ou call it annoying means that the camera has low battery capacity. the lens is stuck out because there is incorrect battery connection. there is an option on the camera setting for the battery type. try this one:
-turn the camera on
-click on Menu button
-select options using left/right, up/down button
-select Set up 2
-Select Battery type
-Select Alkaline for non-rechargable
or Ni-MH for rechargable
-click OK button

this setting should be done when using camera for the first time and whenever you are switching battery types, from rechargable to non-rechargable and vice versa.

It definitely is a matter of the lens. I am having the same problem and after reading your posts here tried playing with the lens and got it to turn on but the lens remains defective. I need to find a fix before i go on my trip to Guatemala in a week!

It means that the camera is having issues with the zoom and the lens moving outward. Usually the case is that something is stuck between the different levels of the retractable zoom. After it beeps, try pulling the outermost rim of the zoom out a bit, then pressing the power button again.

Just an update, sent the camera out for repairs. Nope batteries were not the issue at all, it was caused by a defective zoom.

A lot of ppl are facing this prob, seems common with all dig cams. try using rechargable batteries even i have the same prob diff model .

Your batteries are dead.
