keystroke examples that demonstrate many of the TI

functions. Examples assume all default settings.

turns it off and clears

the display. APD™ (Automatic Power Down™) turns off

the TI

automatically if no key is pressed for about 5

minutes. Press

after APD. The display, pending

operations, settings, and memory are retained.

2-Line Display: The first line (Entry Line) displays an entry

of up to 88 digits (or 47 digits for Stat or Constant Entry

Line). Entries begin on the left; those with more than 11

digits scroll to the right. Press

and

to scroll the line.

Press

to move the cursor immediately to

the beginning or end of the entry.

The second line ( ) displays a result of up to 10Result Line

digits, plus a decimal point, a negative sign, a “x10”

indicator, and a 2-digit positive or negative exponent.

Results that exceed the digit limit are displayed in scientific

notation.

Battery Replacement

Replace protective cover. Place the TI

face down.

1. Using a small Phillips screwdriver, remove screws from

back case.

2. Starting from the bottom, carefully separate front from

back. Caution: Be careful not to damage any internal

parts.

3. Using a small Phillips screwdriver, if necessary, remove

old battery; replace with new one.

Caution: Avoid contact with other TI

components

while changing the battery.

4. If necessary, press

and

at the same time to

reset the TI

(clears memory and all settings).

Caution: Dispose of old batteries properly. Do not

incinerate batteries or leave where a child can find them.

In Case of Diﬃculty

Review instructions to be certain calculations were

performed properly.

Press

and

at the same time. This clears all

memory and settings.

Check the battery to ensure that it is fresh and properly

installed.

Change the battery when:

¦ &

does not turn the unit on, or

The screen goes blank, or

You get unexpected results.

To continue using the TI

Ö†

until you can change the

battery:

1. Expose the solar panel to brighter light.

2. Press
