Time date

i know i set this model before but i recently tried to again and it didn't work right for the time for some reason... but i do remember that you flip the middle switch to rate set, the you put in the date 12.10.08 seperated with a "." then you hit the time date button once. then you do the same with the time, hours(militarytime).minutes.seconds all seperated by a period I.E if it were 1:30 PM you woud put 13.30.00, then you hit the time button again.. the date and time should be set, might have to do it in the opposite order... but i know that is generally how its set
