Canon PowerShot A80 loses date/time settings when turned off

how long has it been since you had it serviced

The world of compact digital cameras is fast and furious blink and you'll miss the new model. These pocket point and shooters are cram packed full of features that most people neglect to utilize. So it's uncommon for the problem you describe to occur however it's simple and fairly inexpensive to repair. What you need is to replace the camera's internal battery which holds the custom functions and date time settings after the camera has been shut off. Normal internal battery life is greater then five years and a lot of my cameras go ten years before replacement. A camera store not your big box type but one that actually sells cameras and does film and print processing. I don't know where you are to even suggest someone. However at the bottom of the camera where you would place the memory card and batteries there is another slot for the internal battery. This link half way down the page will show the open battery door and where the internal battery is located.

There has been few complaints or problem with this camera except for the very weak internal flash.

Have you tried pressing the set/ok button twice at the end of your entering the date and time?

try these:-

• connect it to pc and on it
• vaccum the barrel of lens
• changing mem. card and batt. for 2min.
• shake it.
• on and off in different positions

The menu on the camera controls the date and time stamp. Turn on the menu i camera mode, there are three choices, Camera, Settings and customize. Time stamp should be in the middle menu. Look for time settings and turn it off. All pictures have time and date always. The time/date stamp just makes it visible in the image.

For the A80, this feature only works when direct printing from the camera. Read the section of the A80 User Guide dealing with DPOF printing to set this feature up (Page 141 and above). Here's the user guide direct from Canon:

It may be that the camera is out dated so if you go onto the canon website and find a plug in to down load to your computer then you should be able to run it
