Quick Start
The Tl-84 Plus CE is an easy-to-use graphing calculator
that provides function graphing and data plotting as well
as function and data analysis.
Turning the Tl-84 Plus CE Power On and Off
Press [QNJ to turn the power on; ~ [OFF] to turn it off.
Note: All settings and memory contents are retained by
the Constant Memory™ function.
Using the~ Key
The second function of each key is printed above the key

key. The third functions enter alpha characters, special
symbols, and
access SOLVE:
• Press !ALPHA! [T] to enter T.
• Press~ [A-LOCK] to lock the alpha key in the on
position and enter several alpha characters.
•
Press !ALPHA! [SOLVE] to solve equations entered in the
