The calculator has only six soft menu keys, and can only display 6 labels at
any point in time. However, a menu can have more than six entries. Each
group of 6 entries is called a Menu page. The TOOL menu has eight entries
arranged in two pages. The next page, containing the next two entries of the
menu are available by pressing the
L (NeXT menu) key. This key is the
third key from the left in the third row of keys in the keyboard.
In this case, only the first two soft menu keys have commands associated with
them. These commands are:
@CASCM A CASCMD: CAS CoMmanD, used to launch a command from
the CAS by selecting from a list
@HELP B HELP facility describing the commands available
Pressing the
L key will show the original TOOL menu. Another way to
recover the TOOL menu is to press the
I key (third key from the left in the
second row of keys from the top of the keyboard).
Setting time and date
The calculator has an internal real time clock. This clock can be continuously
displayed on the screen and be used for alarms as well as running scheduled
tasks. This section will show not only how to set time and date, but also the
basics of using CHOOSE boxes and entering data in a dialog box. Dialog
boxes on your calculator are similar to a computer dialog box.
To set time and date we use the TIME choose box available as an alternative
function for the
9 key. By combining the red right-shift button, ‚, with
the
9 key the TIME choose box is activated. This operation can also be
represented as
‚Ó. The TIME choose box is shown in the figure below:
