Hi everyone.

My company have an 4 CH Network support avtech 760 dvr.

and the time and the date are not correct on that device.
i need to change time and date due to the security issue.
but anyway when i changed date time everythings is fine but when i restart the dvr all my setting are set back to default.

i try to look for "battery" something like (Bios battery on PC)
but i can't find any where to insert battery too.

Please i need help. i need to change it to correct date and time.

Please some one help.
Thanks alot

note( this DVR we bought it since 2006 and already over warranty)
