You can access the .pdf manual for your particular calculator here:

Page 1 for how to set date/time:

“RATE SET”: To set the date, time, and tax rate, set this switch at the “RATE SET” position.
Date:
• Enter in the order of month, day and year, then press to complete the entry.
• Use to separate month, day, and year.
• When is pressed, the number entered is evaluated and displayed as “date” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
date is restored.
Month: 1 - 12; day: 1 - 31; Year: 2000 - 2099 (in 4 digits) or 00 - 99 (in 2 digits)
Time:
• Enter in the order of hour, minutes, then press to complete the entry.
(There is no entry available for the seconds value. The clock starts at zero second.)
• If the hour/minute digit is less than 10, it is not necessary to enter the first digit “0”.
• Use to separate hour and minute values.
• When is pressed, the number entered is evaluated and displayed as “time” if the
value is within the following range; “Error” is displayed otherwise, and the previously set
time is restored.
Hour: 0 - 23 (24-hour system for the hour entry), Minute: 0 - 59

It's very simple: the calculators have a default base 10 so that log x it's log x base 10 so here is some logs:
log x base y = log x / log y
log (x*y) = log x + log y
log (x/y) = log x - log y
Hope it's helped

### I don't know how to change the batteries. it seems there is no place to pull out...

When you change your batteries don't take all four out at a time. There is a chance that your back up battery is and you might ruin your calculator. So when you change your batteries, do it one at a time. Try to do it with stealth. This will not reset your calculator, and this will make sure nothing will go wrong.

### Cant find the Log function on the EL 733A

There is no common logarithm function on this calculator. However, you can calculate it easily enough using the natural logarithm function (ln). The log of x is equal to ln(x) / ln(10). In words, calculate the log of a number by calculating its ln then dividing by ln of ten.
