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

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:
