Clock always reset to default upon power up

How do I set the date and time on the FE-170?


To access the clock controls, turn the mode dial to any shooting mode except [GUIDE] and then press the [MENU] button. Next, press the Right arrow on the arrow pad to select the [Setup] icon. Using the Up or Down arrow, navigate to the menu item depicting a clock. Press the [OK] button to access the clock settings feature.
Set the year, month, day, hour, minutes and date format using the following procedure: Use the Up and Down arrows to select values, and press the Right arrow to advance to the next item. (The FE-170 uses a 24-hour clock.) When all information has been entered, press the [OK] button to set the values. Press [MENU] twice to exit the menu.
To set the time precisely, with the cursor on either "minutes" or "date format," press the [OK] button as the time signal strikes 0 seconds.
The date and time settings will be returned to the factory defaults if the camera is left without batteries for approximately three days. Custom settings may be canceled more quickly if the batteries were only loaded into the camera for a short time before being removed. Before taking important shots, check that the date and time are correct.

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.

I probably need more details but, it sound like when you remove the battery to recharge it, the clock loses any power it had. Most people have a second battery. When the first battery begins to lose power, they insert the fully charged battery so the clock is only without power for a few seconds. Try that.

Go to the support section of the Nikon website and e-mail one of their tech people with your problem...I'm sure they can solve it.

On the front panel press "Menu" and enter passcode "4,4,4,4"(Default Admin). you will now be able to change date and time.

setting is not available.
• When there is no daylight saving time in your area,
always select “OFF”.

you'll have to goto settings. choose date/time. then select display date/time.....

The following is from the manual which you can download on the link below: http://world.casio.com/qv/download/en/manual/ So it seems that you must either keep the battery charged or leave the camera connected to the USB dock (with PC on)! If your camera is not keeping the time for the 30 hours stated then it's probably time for a new battery.

There is not an option to remember the date/time when you power off the camera. The camera should always remember the time. If it forgets the setting when you power it off then your backup battery has gone dead. Check your manual to see if it is something you can replace yourself. I am not familiar with this camera specifically but some cameras make the backup battery accessible and some require disassembly. David Millier Advance Camera Repair
