The Set-Up Mode
Another feature of modern calculators is the Set-Up mode. You can manage many
aspect of the calculator from here. Initially this may feel a bit unusual, but once you
get use to this idea you should be alright.
Here are some of the things you can manage in Set-Up:
(i) Setting Date Mode
In both 100V and 200V, the default for day calculation is the 365-day year. If you are
likely to use the 360-day year frequently, you might want to set this as the default.
As you turn on the calculator, tap on .
Scroll down to select [Date Mode :365], then press .
The ‘360’ indicator will appear on top of screen, and the 360-day year will be the
default setting even after you turn off the calculator.
(ii) Setting Date Input Format
In Example 4, we were required to key in dates into 100V/200V. To some people,
inputting date in the Month/Day/Year format is a bit awkward. If you prefer the
Day/Month/Year format, you can set this as your default input format.
Tap on , scroll down to select [Date Input :MDY], then press .
The ‘DMY’ indicator will appear on top of screen, and this input format will be your
calculator default input format.
(iii) Setting Interest Calculation for Partial Month
If your interest calculation involves a period with partial month such as 6 months and
12 days, you can decide on the type of interest calculation for the partial month.
The default setting calculates the interest in a compound manner. If you prefer the
calculation to use simple interest
Tap on , scroll down to select [dn], then press .
The ‘SI’ indicator will appear on top of screen. Calculation done with simple interest
will of course be different to when using compound interest. We will discuss this in
an example in Part 2.
