2.1.3 Work with the ASCII table
Sometimes, you might need to send some
control characters that can’t be typed, or
enter characters without a keyboard. You can
do it using ASCII codes.
In Appendix B, you'll find the ASCII table. Both
column and row numbers are hexadecimal.
The ASCII code of a character is the
combination of a column and a row number,
where the column comes first. For example,
the ASCII code of BEL is "07" and the number
sign (#) is "23." You can use the bar codes in
Appendix D to scan ASCII codes.
2.1.4 Search your scanner
Sometimes you might leave your scanner
somewhere and can’t find it. In this case,
press and hold the RESET button at the
bottom of your cradle, until you receive a
long beep from your scanner, and you can
locate it by the beep sound.

AI-6821/AI-6821HD contains a lithium-ion
battery that is partially charged at the factory.
You might want to charge it to full before your
use it. The battery life varies depending on
