my 600x time slow down everyday

[wchen10]

Hi, Folks

Is there somebody can help me this question? My 600x (4eu)'s time clock is slowing down everyday, usually 10 to 15 minutes slower everyday. The battery of 600x working fine, no idea which battery I should change, or some other parts I need to fix it.

Thank you, and sincerely yours,

Change the CMOS battery. It is under the memory cover on the bottom.

Cool, guys; then what kind of battery is it? Where can I buy it from? Is there any manual so that I can get such kind of info for myself? Appreciate ...
