is the

Pressing it in conjunction
with other Orion keys

Tapping the

restarts the speech function at the
point it left off. Pressing any other

Resetting

The Orion can
occasionally get out of
sync with the TI-84. This
usually happens when the
batteries are changed or if
a bug is encountered.
To reset, turn the Orion TI-84 Plus
off by pressing the
2nd
key
followed by the
On
key. When the
calculator is off, press the

keys together on the
Orion. Then, turn the calculator
back on by pressing the
ON
key.
You should hear the Orion TI-84
Plus power on, at which point you
can continue your work from
where you left off. If the Orion
does not come on, repeat the
above steps. You may need to do
this a couple of times. If it still
doesn't turn on, contact customer
service.
