Question edited for clarity.
Question moved to Victor Calculators.

They have an interesting history.

I don't see anyone listing repairs or restoration. Surprisingly they don't fetch a lot of money, just $60 to $400 depending on model and condition. You might like to restore it yourself?

I have changed block of tvs victor gx and timing chain also but there some sound come from engine

Akkam jirtu fayyaa keessanii abbee abi baayyee akka malee isin yaafaan ture garuu isin ammoo naaf hin yaaddan malee

Immediately after entering the year part of the date, the display should revert back to a blinking first digit (in this case, the 0 to the left of the 8) while retianing all the following digits just entered. Simply press the Time/Date key again to lock in that date and stop the blinking. The same process applies for the time.
To clear the display of the time/date when using the calculator to actually compute something, press the C or CE button. This will result in a 0 appearing on the display. The unit is now ready for data entry.

My machine goes this way-
Hit time/date button.
then enter in date (ie) 11.16.2009--INCLUDE DECIMAL!!!
Then hit time/date button again,

I am still working on the time issue, I just cant seem to remeber, I know it is done off military time.

press the CA button to get your time/day from being displayed. For your date... whenever you press the time button to edit your time, press it again & your date shouold come up. the time/date button are both done with the TIME key.

For the UF-595 here's how you turn the fax stamp on:
Function + 7 + copy/set for enter
scroll to option 4 + copy/set

Hit 04 + copy/set and enter number 2 to turn the fax stamp on. 1 turns it off.
Scroll to or enter 28 and choose 2 to turn the fax stamp on for faxes stored in memory for later use.

You hit the "clear" button to wipe out the current number before you enter 2 or 1 for the new entry.

Hi,
Please change the Leithium battery fixed inside your fax machine, usually this the problem.
If the Date time is running in different date & time.

Please press Menu, then scrolle left of right arrow key. When you find set Date/Time enter the key mentioned in the Display key and change to your date & time.

After some time see if the date/time working normally. If not change the above mentioned battery.

regards.
