There's a negative button and a minus button. I think you're accidently pressing the negative button. The actual subtraction button is the red "-" button above the "+" button. I hope this helps, but if all else fails, you can always add a negative!

If you want to set the time, the button that has a picture of the calendar and clock (just to the right of the arrow key) until it shows the time. Then press and hold the date/time set button (just tor the right of the red minus button) for three seconds until it begins to blink. Then use the arrow key and enter appropriate digits and the am/pm button for am or pm. If you need to set the date, press the calendar/clock button again until it shows either the date or the time, and then hold the date/time set button down for three seconds until it begins to blink. Then use the arrow key and enter appropriate digits.

I'm not sure about this so if it doesn't work, do not accept my answer so you won't get charged.
First, remove the batteries if it has any, then unplug.
Second, check all of the buttons - make sure that none are stuck down.
Let me know.

Obviously, we do not stay in the same vicinity, so I wouldn't know precisely where you can get this part that you are looking for in your area.

I would suggest you contact Canon via phone or email, and they should be able to direct you to their office near you or the nearest dealer close to your vicinity.

To contact Canon, visit www.canon.com, at the top of the page, select your continent and a canon site will open. Scroll down the page, and you should find "Contact Us", Click the "Contact us and you should find Canon's contact there.

This I believe is a good way by which you can get to parts required.

I hope this is helpful.

Good luck.
