How to Clear Your Computers CMOS to Reset BIOS Settings

What seems to be the problem with the date and time?

If you want to change the date and time settings, then you can click on the time on the bottom right corner of your screen. There you can change the time and date settings.
Or if date and time are always changing whatever you do then you would need to change the CMOS battery of your computer.

IS your TimeZone is Correct?
Right click on your clock, choose Adjust Date/Time.
Click Time Zone Tab. Make sure your Time zone is correctly set.


Boot into the BIOS (setup) screens and check the date and time there. If the date is off by years then that verifies you need a new CMOS battery. Do not confuse the CMOS battery with the large external battery you run the computer with.

If some connections were changed then the ALWAYS ON +12 volt to the clock circuit back up is not powered all the time . check if while the battery was changed if there was any link that was disconnected that is the continuous supply to the clock.

it has to be the battery contacts, the motherboard is loosing contact with the battery which is why it keeps resetting itself

most of the cases the main reason behind the date time reset problem occurs due to weak CMOS battery on the motherboard. So, you just need to change your CMOS battery on your motherboard to resolve this problem.

Change the mother board battery it is flat when you change battery you will have to reset BIOS to your time and date
. Also your CPU and memory settings may have to be reset as well

It is really NORMAL that the date will be reset to the Manufacturer's date whenever you are changing batteries.

For you not to keep on changing the date and time of your camera, use Rechargeable batteries for a longer battery life span but make sure that you will be setting the battery type of your camera for the Rechargeable ones.

To set the correct battery type.
- Press on MENU button
- Press on the right button until you see SETUP 2
- Scroll down until you see BATTERY TYPE
- Select ALKALINE if you're using NON-RECHARGEABLE
- Select Ni-MH if you're using RECHARGEABLE
- Press on OK/MENU button for changes to be saved

Turn off camera after the settings
have been changed to refresh the camera.

RESETTING THE CLOCK AFTER A TOTAL MEMORY LOSS

If you do not change the built in lithium battery within a reasonable period of time after you see the ‘flashing’ LOW BATT. warning indicator, the lithium battery may become exhausted and will no longer be able to supply back up power to the SmartSet internal computer.

If the unit is disconnected from the AC outlet after the battery is exhausted, or if a power interruption occurs, the SmartSet memory will be lost and the clock will need to be reset when the power is restored. Be sure to install a fresh lithium battery before you reset the clock, otherwise the clock will need to be reset each time the power is interrupted.

If the lithium battery is exhausted and you experience an interruption in the AC power supply, the clock will reset itself to its initial default setting when the power is restored.

The initial default setting is “12:00 AM, Saturday, January 1
(1 1), 2005”.

If you notice that the time on your SmartSet clock radio is completely incorrect, and the day indicator is also wrong, press the MONTH/DATE button to see the date. If the date display is showing “1 1” (January 1 ), you probably experienced
a total memory loss. To reset the clock after a total memory loss, proceed as follows:

1.) Install a new CR2430 lithium battery in the battery compartment.

2.) Connect the radio to your AC outlet and let the clock set itself.

3.) Depress the MONTH/DATE and TIME buttons together. The display will change from ‘time’ to ‘year’. While holding the MONTH/DATE and TIME buttons, press the UP button to
set the display to the correct year, then release the buttons.

4.) Depress the MONTH/DATE button. The display will change from ‘time’ to 'month/date’ (mm/dd). While holding the MONTH/DATE button, press the UP button to set the display
to the correct month and date. The Day indicator will change automatically as you adjust the month/date settings. When the correct month and date appear on the display, release the buttons.

5.) Depress the TIME button and the UP button to set the display to the correct time. Be sure to confirm that you have set the time correctly to ‘AM’ or ‘PM’ by observing the AM indicator.

6.) After you set the time, reconfirm that the Day, and Month/Date displays are still correct. Make final adjustments if necessary.

The SmartSet clock memory is now reset and the new lithium battery will maintain it for the next 5 to 8 years, depending on the number and duration of the power outages you experience.

IMPORTANT NOTE:
After resetting the clock, don’t forget to reset your wake up times, and alarm mode settings, and sleep timer settings as well.

The manual states that when you change the batteries, you will have to reset the date and time; this is normal operation for this camera (though it is a pain!!!)
