Procedure † One- or two-*1 digit number @ Rate*2 @ max. six digits (0.0001 - 99.9999%) M max. four digits @ T max. three digits @ Q max. five digits @ Minimum breakpoint max. five digits @ Repeat until the MAX point is entered. Ç *1 First figure: The first figure to be entered depends upon whether the difference between a minimum breakpoint to be entered and the preceding minimum breakpoint is not less than $1.00 or more than 99¢. When the difference is not less than $1.00, enter "1," and when it is not more than 99¢, enter "0" or nothing. Second figure: The second figure depends upon whether your tax table is to be programmed as tax table 1, 2, 3 or 4. When your tax table is to be programmed as tax table 1, enter "1"; when it is to be programmed as tax table 2, enter "2"; when it is to be programmed as tax table 3, enter "3"; and when it is to be programmed as tax table 4, enter "4". *2 If the rate is fractional (e.g. 4-3/8%), then the fractional portion (3/8) would be converted to its decimal equivalent (i.e. .375) and the resulting rate of 4.375 would be entered. Note that the nominal rate (R) is generally indicated on the tax table. Note If you make an incorrect entry before entering the M in programming a tax table, cancel it with the c ı key; and if you make an error after entering the M, cancel it with the key. Then program again from the beginning correctly. • Limitations to the entry of minimum breakpoints Your register can support a tax table consisting of no more than 72 breakpoints. (The number of breakpoints is 36 maximum when the breakpoint difference is $1.00 or more.) If the number of breakpoints exceeds the register's table capacity, then the manual entry approach should be used. Example Programming the sample tax table shown on the previous page as tax table 1 Key operation Tax rate ¡ M ¡ T ¡ Q ¡ The first cyclic portion M1 (MAX point)¡ † 1 @ 6 @ 100 @ 1 @ 11 @ 23 @ 39 @ 57 @ 73 @ 89 @ 111 @ a Print Note You do not need to enter the trailing zeros of the tax rate (after the decimal point) but you do need to enter the decimal point for fractions. 79
