This equipment has been tested and found to comply with the
limits for a Class B digital device, pursuant to Part 15 of the FCC
rules. These limits are designed to provide reasonable protection
against harmful interference in a residential installation. This
equipment generates, uses, and can radiate radio frequency energy
and, if not installed and used in accordance with the instructions,
may cause harmful interference with radio communications.
However, there is no guarantee that interference will not occur in
a particular installation.
If this equipment does cause harmful interference to radio or
television reception, which can be determined by turning the
equipment off and on, you can try to correct the interference by
one or more of the following measures:
• Reorient or relocate the receiving antenna.
• Increase the separation between the equipment and receiver.
• Connect the equipment into an outlet on a circuit different
from that to which the receiver is connected.
• Consult the dealer or an experienced radio/television
technician for help.
Caution: Any changes or modifications to this equipment not
expressly approved by Texas Instruments may void your authority
to operate the equipment.

Generally, the keyboard is divided into these zones: graphing keys, editing
keys, advanced function keys, and scientific calculator keys.
Graphing keys access the interactive graphing features.
Editing keys allow you to edit expressions and values.
Advanced function keys display menus that access the
advanced functions.
Scientific calculator keys access the capabilities of a
standard scientific calculator.
