General Information
The TI-10 has two power sources — battery and solar. It
operates in well-lit areas using the solar cell, and it operates
in other light settings using the battery.
Examples: See the "Examples" page for problems with
keystroke sequences that demonstrate many of TI-10
functions and capabilities. Before starting each problem set,
reset and clear the TI-10 by pressing
ensure that your displays are the same as those shown in
the examples. In Problem Solving AUTO mode, however,
displays will vary from those shown in the examples
because the problems presented by the TI-10 are random.
On/Off

To turn the TI-10 on, press
−
If the TI-10 is on, press to turn it off.

Two-Line Display and Scrolling
The TI-10 has a two-line display that shows up to 11
characters at a time on each line. Entries that do not fit on
the first line wrap to the second. When the second line is
filled, the characters scroll up.
Entries can be up to 88 characters. Exceptions : For Op1
(Stored Operation), the limit is 44 characters. For ‹
(Problem Solving) MAN (manual) mode, entries do not
wrap; entries cannot exceed 11 characters.
When a result exceeds the capacity of the display, it is
shown in scientific notation. However, if the result is greater
than 10 , an OVERFLOW ERROR is displayed; if the result
99
is less than 10 , an UNDERFLOW ERROR is displayed.
